With more than 39 million people , California is the most populous state in the country. Unofficially divided into northern, central, and southern regions, the state has beaches, deserts, farmland, and mountains.
"California is probably unique in its diversity. It's almost not one state economy. It's maybe 10 or 14 regional economies depending on how you look at how industry sectors are organized," says Tim Rainey, executive director, California Workforce Development Board.
The outlook for the green economy is as far-reaching as the state itself. "We're doing everything in California with an eye toward reducing carbon in the atmosphere. In a way, you could almost define everything we do in California as green jobs," says Rainey.
According to our report Green Jobs Now: California, a new WorkingNation and Lightcast analysis of the green labor market in the state, there are already more than 210,593 workers in California's green economy.
The report projects in the next five years, employment for green jobs in the state will increase by 7.1%, well above the national average of 5.7%.
Assembly Bill 398 - intended to mitigate climate change - also calls for the creation of good jobs.
When passed, the legislation tasked the California Workforce Development Board to report "on the need for increased education, career technical education, job training, and workforce development resources or capacity to help industry, workers, and communities transition to economic and labor-market changes related to specified statewide greenhouse gas emissions reduction goals."
A 2020 report from the UC Berkeley Labor Center offers a breakdown of AB 398, stating, "California has emerged as a national and world leader in the fight to avoid climate disaster, passing a comprehensive and evolving suite of climate measures to accelerate the transition to a carbon-neutral economy."
Putting California on the High Road: A Jobs and Climate Action Plan for 2030 also says, "The state has also emerged as a national leader in embracing economic equity as a goal for state policy."
Rainey notes, "We need to be really clear that when we talk about jobs, we have to focus on quality jobs. And if we want to achieve equity, you can't separate quality jobs from equity. We're not going to put poor people in bad jobs because that's not going to move the needle in equity."
"Our state and federal governments are investing historic levels of funding in infrastructure focused on climate, green jobs. We have an opportunity to put in those investments workforce standards that help set up our ability to put people in good jobs."
Rainey points out, "The employment is going to be in those traditional occupations that largely don't require college degrees. As the demand for apprentices increases, the demand for construction workers increases - filling the pipeline in a way that has real intentionality around impacting equity is our focus. We have really beautiful programs across the state we call high-road construction careers that do just that."
"Our role in is to fill the pipeline with people who don't look like your traditional tradespeople - more women, more people of color, lots of focus on the formerly incarcerated - so we can start getting at those equity goals and showing that in the data."
Green Jobs Growth in The Golden State
"Workers with green skills are also spreading across a wide range of industries - such as utilities, manufacturing, and professional services - illustrating the increasing need for green skills across California's economy," according to Green Jobs Now: California.
California's Green Workforce is Moderate and Growing: As stated, there are over 210,593 workers in California's green economy, and there were 53,587 green job openings in the state in 2022.
By comparison, this is more than twice the number of Pharmacy Technicians and Forklift / Pallet Jack Operators demanded in California in 2022.
Demand for Green Enabled Jobs is Strong and Green Jobs Are Spreading Across Industries: Demand for green enabled jobs, that is, workers in roles that are not considered green by default, but who are required to have at least one green skill or competency, is significant, with 38,455 openings in 2022.
Workers with green skills are also spreading across a wide range of industries - such as Utilities, Manufacturing, and Professional Services - illustrating the increasing need for green skills across California's economy.
What is a Green Job?
We look at four different categories when we break down the opportunities in the green jobs ecosystem.
Core jobs have "a primary responsibility associated with the green economy." The data indicates a top core green job in California is a solar sales representative.
Enabled jobs have "primary responsibilities separate or tangential to the green economy" with building and general maintenance technicians identified as primary jobs.
Not to be confused with enabled jobs, enabling jobs "aren't associated with green tech per se, but they support the green economy."
Green Jobs Now: California finds there are about 5.8 million workers in the state who, with new skills, could be green workers. "These workers come from a variety of different occupations and educational backgrounds and reskilling them could build the pipeline of green workers faster than relying on new postsecondary graduates alone."
"However, doing so will require a mix of training program formats that support the reskilling and redeployment of these workers."
The most in-demand skills related to core green jobs in California are solar sales and solar energy.
The report says, "For workers in many core and enabled occupations, there is a significant salary boost for having green skills and competencies on their resume." For example, a quality inspector/technician commands an average annual salary boost of more than $8,000.
Findings state, "From the most in-demand green skills, workers interested in entering the green workforce can prioritize what skills and competencies to acquire."
Key green skills offer significant annual salary increases of $1,600 for skills related to wind power and $5,800 for carbon management skills.
According to the data, the average green jobs salary in California is $67,252.
California's Agricultural Sector
"Over a third of the country's vegetables and three-quarters of the country's fruits and nuts are grown in California," according to the California Department of Food and Agriculture (GDFA). "In 2021 California's farms and ranches received $51.1 billion in cash receipts for their output."
The farming community increasingly shows strong interest in sustainability, according to Steve Lyle, director of public affairs for the department. "CDFA's climate-smart agriculture incentive programs have continued to grow in popularity such that now they are oversubscribed every year."
"The purpose of our incentive programs is to support them in taking those first steps of trying new sustainable practices in their operations, and hopefully making a business case for continuing those practices beyond the lifetime of their CDFA grants."
Lyle offers advice for the agricultural community, "Take advantage of climate-smart programs, like OEFI [Office of Environmental Farming and Innovation] offers, and the technical assistance its vast network provides to understand which programs and systems will work best for any given farmer or grower in California."
He explains that technical assistance - which is provided to farmers and ranchers at no cost - can include support through the "planning, execution, and closeout processes of our soils, water efficiency, and manure management incentive programs, in addition to funding some programs that offer broader technical assistance for conservation agriculture."
Lyle notes, "Many colleges and universities offer certificate programs in agricultural sustainability." These include UC Davis's bachelor of science degree in sustainable agriculture and food systems and Santa Rosa Junior College's associate degree and two certificates in sustainable agriculture.
Looking forward, he says, "We believe that farmers and ranchers see the challenges of a changing climate and want to pursue strategies that increase their resiliency while being good stewards of the land for future generations."
Pathway into Green Infrastructure
"Since our formation, we've been bringing labor and environmental groups together to really tackle labor and climate issues at the same time," says JB Tengco, vice president of state affairs at BlueGreen Alliance - which includes 10 state-based teams, including California.
Tengco notes that addressing the mission in California is "complicated."
"If you look at California - from the size of its economy, the size of its energy need, the energy diversity that we have here, we have everything you can think about in terms of needs for the economy and to really help the state operate. When you add all that together, the complexity of what we're trying to accomplish with the energy transition is definitely daunting and big."
"I think a lot of folks within the state - from elected officials, to working families, to labor, to industry - are really looking at how do we ensure, that as our energy generation and our energy needs change, that we're doing so in a way that creates good jobs."
Referencing state legislation, Tengco says, "The AB 398 report tries to map out different sets of labor levers to go with climate policy."
He continues, "Climate policy has two components, the climate policy and the proactive labor lever. It's the combination that ensures that you create good jobs. We know there's a difference between a job and a good job."
Tengco notes, "Labor has clearly led on addressing some of those issues around systemic inequality. Historically, you've seen that for a lot of people of color, their abilities to get higher wages, promotion paths, health care have come from working with labor. We've seen a lot of opportunities for people of color to have jobs that are family-sustaining. California has done a lot to recruit from targeted communities - be it people of color, formerly incarcerated, women - into the trades themselves."
Opportunities in the Green Economy
"In the clean energy space, we clearly see the energy generation - from renewables like solar and wind, both onshore and offshore as areas for good job creation," says Tengco.
"As we look at trying to build new energy generation facilities, more and more of that is done with labor. Also, as we move to making buildings more energy-efficient, there's been a lot of good labor work within that. I think increasingly as we look at manufacturing, both California and the country are really thinking through how do we onshore manufacturing? How do we do so in a way that leads to good jobs?"
"What you're seeing is a lot of the crafts continuing work and expanding their work as new opportunities arise. When you really think of what solar generation is, it's energy generation. Electricians who have been working on powering homes, powering buildings, powering industrial sites, solar is just another mechanism to create electricity. You're actually seeing a lot of the trades move that way and have already incorporated a lot of these new technologies in their trainings."
"You see the same with HVAC systems, right? HVAC systems create clean air within schools, hospitals, and whatnot. As that technology changes to become cleaner, they're moving into or expanding their skillset to work on different types of [cleaner] technologies."
An Oakland-Based Nonprofit is Creating Access to Quality Jobs
"Rising Sun as a pre-apprenticeship program is exactly the type of program that the trades partner with to ensure that they are getting people of color, women, local hires into the trades," explains Tengco.
"We've always had this mission that's been at the intersection of equity, climate, and jobs," says Julia Hatton, president and CEO at Rising Sun Center for Opportunity - an Oakland workforce development organization that provides training and employment programs.
Originally founded in 1994, Hatton explains the organization's current Climate Careers program was spearheaded by a student-led effort in 2000. "We had staff who were teaching a class on climate change at Berkeley High. It was actually the students in that class who decided that they didn't want to just learn about this stuff. They wanted to go out and make a difference in their own communities. They went to the homes of their friends and neighbors and took out the old inefficient lighting and water fixtures, and replaced them with new, efficient versions of those things."
"We now run that program across the 10-county area in the Bay Area and Central Valley. The emphasis of that program is the youth employment and the youth development piece - giving young people, not just their first green job, but their first [paid] job. Period."
Climate Careers whose participants are between the ages of 15 to 24 - includes a leadership pathway for the older youth.
After a week of paid training, the participants work during the summer months making green house calls. From September through November, the youth are placed in paid externships with partners working in the climate space. Among them - Redwood Energy, Lawrence Berkeley National Laboratory, and Stockton Service Corps.
"We collect feedback cards from every green house call - to see the feedback that comes back about the young people, 'They were so professional. I'm so impressed I learned this thing that I didn't know. I want to hear more from these kids. The youth are our future.' That can be really transformative. On the youth side, it's empowering to know that adults react in that way."
About 80 youth participate in the program, visiting about 3,000 households during the summer - with wages at about $19 an hour.
Pathway Into Union Membership
Rising Sun's Opportunity Build - an industry-certified construction training program - provides a path to union apprenticeship in the skilled trades. "One of the key things that union membership offers is that ongoing training, retraining, and reskilling," says Hatton.
The organization has three cohorts around the skilled trades training.
"We have an all-women's cohort called Women Building the Bay. We have a nights and weekends cohort that runs in the summer that's tailored for folks who might have a job that they need to be at during the day. And then we have a regular cohort in the fall. Across all the cohorts, at least 55% of our participants are women. About 40% are system-impacted which could include coming home from incarceration or having other interaction with the justice system. All of our participants in Opportunity Build are facing some pretty high barriers to employment" - including housing instability and food insecurity.
"We do 10 to 12 weeks of training, but then it's 12 additional months of services after they graduate to support the job placement, the job retention, and, ultimately, the career advancement."
Participants might receive a stipend of a thousand dollars and support services that can include initial union dues, unpaid parking tickets, rent, and childcare.
The Need for Union Labor
"Wind turbines or our highways and roadways - making sure those are going be resilient to climate change, to heat, to flooding, to whatever it is. That's union labor. That's organized labor. That's the building and construction trades," Hatton points out.
She says IBEW Local 332 is well-suited to provide skills training, "They have whole classrooms, whole labs dedicated to battery storage training to EV charging, all those things. When you think about climate infrastructure, that's union labor."
Regarding UA Local 342, Hatton notes, "They're training their apprentices on heat pumps and that's a huge piece when you're looking at building electrification and decarbonization, right?"
Employment in the green sector must mean - not just a job - but a quality job, explains Hatton. "There is an interesting differentiation between residential sector work and work that tends to be organized and unionized which, not exclusively, tends to be more at the commercial or infrastructure scale. That differentiation is really important when you start thinking about job quality."
One Apprentice's Journey
"I took a liking to construction through my grandfather. I found it interesting watching my grandfather work on the sink or rebuild his kitchen, his bathroom, his roof," recalls Ashley Lewis, now a laborer apprentice, Turner Construction Company in Oakland.
"He would just catch me standing there just watching him and he'd just be like, 'Why don't you come over and help?' I'd help lay tiles on the floor, help him replace a couple pipes underneath the sink. I learned to paint a room with my grandfather."
Lewis initially applied for the Rising Sun pre-apprenticeship program a few years ago but the training opportunity was put on hold due to the pandemic. When programming resumed, Lewis applied for the February 2022 all-women cohort with about 20 participants.
She says, "It was all women. I loved that women empowerment, that unity, that sisterhood. We all built a really great bond."
The Rising Sun training gave the participants a lot of experience, notes Lewis. "We ended up getting lots of hands-on training with different tools you might use in different trades like cementing, woodcutting, leveling, mapping."
Prior to her pre-apprenticeship training at Rising Sun, Lewis did in-home care and worked at various odd jobs. Her laborer apprenticeship with Turner began in February of this year.
Lewis is currently working on a project at Oakland International Airport. She says the company has protocols in place to be environmentally safe. "Because there's a lot of welding, a lot of different equipment and chemicals being used, they have these big filtering fans throughout the [walled-off] areas where we're working. That way the fumes and the dust - everything [is kept] at a minimum."
"We don't know how old certain things in the airport are - so trying to keep things contained and from spreading, we have the air filtration systems constantly going and making sure that not only are we safe, but everyone outside the walls is safe."
She says her company is employing green practices in its work. "I think Turner is definitely keeping that in mind. I see all the different recycling bins for metal, for waste, for miscellaneous items. And making sure, because we're at the airport, it doesn't get into the water because we're surrounded by the water. And making sure other things stay covered, locked, and secured.
She continues, "I see them taking steps, putting signs up around the airport, letting people know that there's construction work going on and how we have restricted zones."
Lewis hopes her union pathway will lead to her becoming a journeyman.
The Green Economy and Quality Green Jobs
"You bring in the workforce training components that skill people up so they can take those jobs. You can do that across these investments in ways that really drive not just improving the infrastructure, but really gets to regional and local economic development that starts to impact employment in regions," says the CWDB's Rainey.
Tengco of BlueGreen Alliance says, "When I first started working with BlueGreen, I talked to elected officials, I talked to companies, I talked to a whole host of different allies and partners. We talked about addressing environmental issues, and we talked about the need to create good jobs. Often, I had to answer the question, 'Why do we need to create good jobs? Why do we have to be proactive? Aren't we creating jobs? Isn't that good enough?' I'd say over the years, that the question is no longer 'Why?' but 'How?' And that is what makes me optimistic about what we do."
Rising Sun's Hatton says, "The quality of those jobs is so essentially important. Not just the wages, but the benefits, the scheduling, the worker protections, all of those pieces. It's not just the training. It's all the wraparound pieces, all the supportive services, making sure there are pathways, and that people are prepared to advance on those pathways."
"You have the climate part of the mission that's so important. It has to happen fast and it has to happen everywhere, but how can we make sure those opportunities are also uplifting economically? That's a big question."
Apprentice Lewis frequently talks with her grandfather about her career pathway. "He says, 'When you enjoy something, it doesn't matter what you're doing. Time doesn't exist and before you know it, your day is over.' My grandpa was at the school district for over 30 years and he retired - now I see what he meant because he stayed there for 30 years."

Broadcast version by Edwin J. Viera for New York News Connection reporting for the Sentient-Public News Service Collaboration
As the calendar flips to a new year, media outlets are once again publishing their annual advice for eating healthier and living better. This year, health reporters continue to be obsessed with the problem of ultra-processed food. And while we are happy to see journalists include research-backed guidance in their coverage, on the whole, our health news feed seems to be missing some vital information.
This year’s crop of healthy eating stories seems to be getting some things right — limiting ultra-processed foods and adding more plants to your diet among them — but journalists and editors continue to miss opportunities to report on health from a broader perspective, one that includes the climate impacts of meat.
Matthew Hayek, assistant professor in the Department of Environmental Studies at New York University, tells Sentient that there’s a general lack of awareness among both the public and the media “about how many resources meat and dairy production really requires,” and “that awareness could really benefit a lot of coverage of this issue.”
Hayek believes there is concern among reporters that “discussing sustainability and diet can feel like piling on to what is already a very fraught, personal and cultural issue.” However, Hayek adds, “what’s really infrequently discussed is that healthy diets and sustainable diets are largely the same thing.”
Trend #1: A Focus on Ultra-Processed Foods
One of the most popular reported topics related to healthy eating in 2025 is undoubtedly ultra-processed foods. Questions about which foods actually qualify as ultra-processed, and how much of them we should and should not be eating, continue to pique reader interest. But while there is a growing body of research raising concerns about ultra-processed foods, not all media coverage is providing readers with a clear picture of the science.
The Washington Post and the New York Times both took on the topic of ultra-processed foods in their New Year’s resolution coverage this year, with the New York Times’ “The Well Challenge: 5 Days to Happier, Healthier Eating” kicking off an entire series on ultra-processed foods. “We’re not just paying attention to the nutrients in our food,” the article reads. “We’re also looking for clues to tell whether a food was processed — and if so, how much.”
What we know: a growing body of studies suggests ultra-processed food consumption might be linked to an increased risk of a host of health problems, including obesity, heart disease and cancer. These foods, which make up more than half of the calories consumed at home in the U.S., are optimized to bypass our body’s natural satiety cues, which can lead to eating more than you intended.
But researchers do not agree on, nor do they know for sure, what it is about ultra-processed food that is the culprit. In fact, there is still fierce debate over the category itself. As the Washington Post reports, “not all ultra-processed foods are created equal.” The Post’s story on “healthier processed foods” explains that some foods deemed ultra-processed by some researchers, such as sliced bread and peanut butter, can be part of a healthy diet.
Kevin Hall, nutrition and metabolism researcher at the National Institutes of Health, said this to the New York Times: “Not all ultra-processed foods are necessarily bad for you,” and not all unprocessed foods are good for you, either. “Just because Grandma made it, doesn’t make it healthy.”
For Teresa Fung, professor of nutrition and dietetics at Simmons University, and adjunct professor at Harvard University’s T.H. Chan School of Public Health, whether a food is ultra-processed matters less to her than what it’s made of. “It really depends on what the food is,” she told Sentient. “The things I would rather look at are the ingredients list, as well as the nutrient content.”
Not only does coverage of this topic tend to confuse people about what’s good for their own health, but the lack of clarity can have major consequences for climate action. The reporting often overlooks or even discourages the very shift that climate experts are encouraging in the global north to reduce environmental impact: plant-based diets.
Case in point: media coverage positioning plant-meats as ultra-processed and unhealthy. This narrative emerged a few years back, with some links to the meat industry emerging even, and continues to this day.
For example, a Lancet study published in 2024, examining how ultra-processed foods affect heart health and mortality risk, led to outlets including the Daily Mail, New York Post and People magazine linking (incorrectly) plant-based foods to increased heart disease risk. In that study, plant-based meats made up only 0.5 percent of participants’ diets, among other “plant-based” ultra-processed foods like biscuits and soda.
More recently (and more accurately), the New York Times summed up the issue of plant-based meats being roped into the processed foods narrative as follows: “If plant based meat must be categorized as processed food, the argument is that they are more like canned beans than Twinkies, and a long way from processed meats, the category that includes hot dogs, bacon and deli meat, which the World Health Organization has classified as carcinogenic to humans.”
However, this broader take on ultra-processed food was part of The New York Times’ climate coverage, not its New Year’s Resolution health coverage; another example of how climate coverage is often siloed from the rest of the newsroom, leading to conflicting information from story to story.
Trend #2: Still Ignoring Planetary Health
One diet often touted by the media as one of the healthiest is the Mediterranean Diet. This diet, according to CNN’s “2025 best diet wins gold for wellness and disease prevention,” focuses on fruits, vegetables, grains, olive oil and nuts, with limited dairy, meat and sweets.
CNN and others get the personal health angle here right. According to Harvard School of Public Health, “research has consistently shown that the Mediterranean diet is effective in reducing the risk of cardiovascular diseases and overall mortality.” But once again, the news coverage tends to leave climate and other environmental concerns out of the discussion of what constitutes healthy food choices, by encouraging a shift to fish from meat without mentioning any of the tradeoffs.
As climate change grows worse, fish will become harder to count on as a food source. According to one paper on the Mediterranean diet, published in the American Heart Journal Plus, which touches on this concern, “rising sea levels and ocean temperatures can disrupt marine ecosystems, affecting fish populations.”
The practice of overfishing also creates serious climate impacts. Oceans can absorb around 31 percent of carbon dioxide emissions and store 60 times more carbon than the atmosphere, with billions of sea creatures, from sardines to whales, sustaining this cycle. As Heidi Pearson, a marine biology professor at University of Alaska Southeast, told Sentient in 2024, “The more fish we take out of the ocean, the less carbon sequestration we are going to have.” According to rough calculations by Sentient, ending the practice of overfishing would store the same amount of carbon as 6.5 million acres of forest each year.
One of the most highly consumed fish, salmon, comes with a host of environmental and ethical issues. An estimated 70 percent of the world’s salmon now comes from fish farms, where crowded conditions promote disease spread, leading to increased antibiotic use and resistance in humans. Escaped farmed salmon can also threaten wild fish populations, and aquaculture waste can pollute surrounding ecosystems. Yet in most healthy eating coverage, you rarely hear more about salmon beyond the fact that it is a healthy source of omegas.
In its “10 Tips to Help You Eat Healthier in 2025,” The New York Times does a little better by mentioning the environmental impact of seafood. It highlights bivalves — clams, oysters, mussels, and scallops — as more sustainable sources of protein, “without the environmental baggage of many other seafood options.”
Worth pointing out, however, that not every researcher agrees. Ecologist Spencer Roberts tells Sentient via email, while bivalve farms may have some environmental benefits, they are “a sad substitute for an oyster reef,” and reintroducing bivalves in restoration projects offers more ecological value than aquaculture operations.
Trend #3: Plant-Based Eating Is in, Fully Plant-Based Diet? Not So Much
With all the talk of health and wellness in the New Year, it’s inevitable that newer diet fads dominate the news. In Newsweek’s coverage of “Food Trends to Embrace in 2025, According to Scientists,” the outlet tackles hot topics like gut health, intermittent fasting, and of course, ultra-processed foods. It also takes on the social media-hyped carnivore diet — eating almost exclusively meat and other animal products — in comparison to a plant-based diet.
First, let’s talk about what Newsweek’s expert, professor and author Tim Spector, gets right. He does not recommend the carnivore diet, which lines up with what most registered dietitians have to say. He also told Newsweek, “You don’t need to become vegan, but adding more vegetables, legumes, nuts and seeds, whole fruits and whole grains while reducing red and processed meats is a winning strategy.” He’s not entirely wrong, especially when it comes to personal health. Eating more plants, and less meat, is both good for you, and it’s also good for the planet. But does continuing to position “vegan” as extreme (like the carnivore diet) give readers useful and accurate information?
In much of the current mainstream news coverage on healthy eating in the New Year, this appears to be a common theme: focusing on plant-heavy diets, without suggesting people eat plant-exclusive. Whether it’s the Mediterranean diet, DASH diet (or the MIND diet, which combines the two), Flexitatianism or Reducetarianism, mindfully eating less meat and more plants continues to be an evolving trend.
Presumably Newsweek wants its readers to know that eating habits don’t have to be all or nothing. If a vegan diet seems too challenging, eating less is certainly progress from decades past. (We’ve made similar points here at Sentient, too.) But people care about climate action and they also care about animal welfare, according to polling research. What to eat is an individual choice, but these choices have impacts, and good journalism has an obligation to include that information.
Eating a vegan diet has well-documented environmental benefits, even at the individual level, including cutting one’s climate emissions by about 75 percent, and water usage by over half. At the global level, a shift to a plant-based food system would reduce global agricultural land use by an estimated 75 percent, freeing up those spaces for the kind of crucial rewilding that can help offset emissions.
As the accelerating effects of climate change are becoming more and more visible, perhaps 2026 New Year’s Resolution coverage will see mainstream media make the connection between planetary health and personal diets — trending or not. “There’s a lot of room for win-wins here,” says Hayek, as “diets that are more healthy are more sustainable, and vice versa.” He suggests that journalists reporting on healthy eating seek out environmental scientists, like himself, to get the bigger picture.

By Seth Millstein for Sentient.
Broadcast version by Mark Richardson for Ohio News Connection reporting for the Sentient-Public News Service Collaboration
In an unexpected but no-less-depressing development, NASA has announced that 2024 was the hottest year on record. This wasn’t an anomaly, as every one of the past 10 years has been one of the 10 hottest years in the planet’s history. Climate change is a serious problem in need of a serious solution — but what counts as a viable climate solution, and what doesn’t?
It’s not an easy question to answer. In fact, you might even say it doesn’t have an answer, at least not a single one. While there is certainly widespread agreement about the need to decarbonize, there is also an ongoing debate among climate scientists about which solutions to prioritize and when. That debate is important, as there’s no single “silver bullet” for bringing down global temperatures, so we have to have these difficult conversations.
“This is pretty hard, right?,” University of Hawaii Oceanography Professor David Ho tells Sentient. “If we’re talking about carbon dioxide removal, basically, you’re talking about the largest thing that humanity has ever done.”
This illustrates the enormity of the task at hand. It’s the “largest thing humanity has ever done” — and Ho isn’t even talking about reducing our emissions across the board. He’s merely talking about carbon dioxide removal, which as we’ll see, is just one element.
Although there’s disagreement around how best to fight climate change, the contours of these disagreements are illuminating, because they’re often about deeper divides and tough decisions.
Climate Solutions, Defined
First, let’s talk about basic definitions. When we talk about climate change, we’re usually talking about rising global temperatures. Greenhouse gases — primarily carbon dioxide, methane and nitrous oxide — are the main reason temperatures are rising.
That’s why Amanda Smith, senior scientist at the climate organization Project Drawdown, argued in a 2024 webinar that any climate change solution must, by definition, reduce the concentration of greenhouse gases in the atmosphere.
This can be accomplished in two ways: by reducing the amount of carbon dioxide we emit in the first place, and by trapping and storing carbon dioxide that’s already been emitted. The first approach is commonly referred to as decarbonization, while the second is known as either carbon capture or carbon removal, depending on the method used.
How to Prioritize the Best Climate Solutions
Here’s where things get trickier. Although many burgeoning climate technologies and innovations have potential, Smith argues that only the ones that can effectively be deployed now can truly be considered solutions. High costs, logistical burdens, legal hurdles and other obstacles mean that many potential solutions aren’t yet ready for prime time.
Smith also argues that a climate solution isn’t much of a solution if it simply offloads carbon emissions to another sector — or causes other environmental damage that isn’t strictly emissions-related, like freshwater pollution. Or, if you advocate for better treatment of farm animals, you might argue that just switching from beef to chicken isn’t a great solution either, because it increases suffering for billions of chickens.
Humanity is facing some tough choices, Ho says. In his opinion, it’s not necessarily a dealbreaker for a climate solution to cause some collateral damage to the environment, so long as the net environmental impact is positive. Climate change will eventually render our planet unlivable if left unchecked, and so we can’t afford to reject effective solutions just because they have negative side effects that, in the grand scheme of things, are less consequential than the consequences of doing nothing.
“It’s the whole trolley problem thing,” Ho says, referring to the philosophical thought experiment that poses a quandary about whether it’s worth diverting a trolley to save five people at the expense of one. “Climate change is going to affect a lot of organisms. If we deploy a solution and it negatively affects, you know, one whale, versus if climate change kills 10 whales, which one do we choose?”
What Factory Farming Has to Do With Climate Change
Climate research suggests there is no way to stave off the worst of global warming without addressing food-related emissions. Our global food system is responsible for around a third of all greenhouse gas emissions, and most of that third is fueled by the meat we eat, especially from cows.
The vast majority of meat comes from factory farms. But to be clear, all kinds of meat production, whether industrial or small-scale, have a negative impact on the environment. Even so-called extensive farming operations, like regenerative or organic, that tout better treatment of animals and reduced use of synthetic chemicals, exact an unavoidable climate cost in the form of enormous land usage — at least, if we’re talking about beef.
Why Beef Production in Particular Has to Be Addressed
Although all types of meat production pollute the environment to some degree, beef is responsible for the largest climate impact, and there are two big reasons why.
Deforestation
First, there’s the removal of trees (and other uncultivated landscapes like peat bogs) that are staving off the impacts of climate change. Agricultural expansion is the culprit behind 90 percent of deforestation, and beef farming in particular is the leading driver of deforestation worldwide.
When trees are removed and peat bogs are drained, the carbon dioxide that’s so helpfully trapped there is released back into the atmosphere. Worse than that, we also miss out on the climate protection these landscapes would have provided for well into the future, something scientists call the “carbon opportunity cost.”
Methane From Cattle Burps and Farm Animal Waste
The biology of the cows themselves is the other factor here, as they are a huge contributor to factory farms’ climate pollution. Cows’ burps, farts and waste all emit methane, one of the most potent greenhouse gasses there is, and so cattle ranches and dairy farms continually release massive amounts of greenhouse gases into the air on a daily basis.
On a more positive note, the flip side of this is also true. Tackling methane emissions, whether by fixing gas leaks or eating less meat, is an opportunity to curb climate pollution quickly.
4 Potential Climate Solutions, and Their Viability
There is plenty of agreement about many of the broad strokes of climate action — curbing dependence on fossil fuels, the need to electrify the grid and even the benefit of plant-forward sustainable diets, for instance. Yet there is also debate about what the path to a better future should look like.
Some favor modest changes to existing systems, whereas others insist on full-scale reform, or even abolition, of those systems. Some focus squarely on one high-emissions sector — for instance, agriculture or fossil fuels — while others support what Smith calls a “tapestry” of solutions across many industries. There are also fierce debates about the role of technology, whether the solution is cultivated meat, nuclear energy or carbon storage pipelines.
Let’s take a look at the debates over a few proposed climate solutions, as each illuminates a deeper philosophical divide.
1. Decarbonization & Carbon Removal
As mentioned earlier, there are two ways to bring down the concentration of CO2 in the atmosphere: reducing emissions at the source, or removing CO2 that’s already been emitted. Both approaches are necessary if we want to eventually reach net-zero carbon emissions, because some emissions — such as those from airplanes — will never be eliminated entirely.
A lot of companies have invested heavily in technology that removes carbon dioxide from the air. That’s one of the upsides to carbon removal as a strategy: it has a lot of buy-in and money behind it, including from major polluters like Exxon. This is largely because it doesn’t require them to actually reduce their carbon emissions.
Carbon Capture Is Slow and Costly
The various methods we have for trapping carbon from the atmosphere don’t do so nearly fast enough to compensate for the amount of carbon we emit on a daily basis. It’s like using a teaspoon to empty out a boat that’s rapidly filling up with water: it won’t work.
For this reason, Ho argues, we first need to dramatically reduce how much carbon we emit before deploying technology to remove it from the air.
“It will always cost more energy to do the removal than to not emit it in the first place,” Ho tells Sentient. “So we really should concentrate our energy on decarbonization, and not putting the CO2 into the atmosphere [in the first place].”
2. Digesters
Digesters are essentially large, oxygen-free containers that take organic waste, like animal manure, and turn it into something else, kind of. The digester, or reactor, contains microbial communities that are specifically designed to break down the manure and convert its emissions into biofuel. This fuel can then be used by cars and other vehicles.
The dairy industry has been a particularly vocal proponent of digesters, which received millions in funding from the Biden administration through the Inflation Reduction Act. Much like carbon removal technology, digesters have buy-in from polluting industries like pork, dairy, oil and gas, and don’t require any large-scale change to how these industries function.
But in practice, digesters come with plenty of downsides that cast doubt on their efficacy.
Digesters Are Expensive and Seem to Entrench Factory Farming
To begin with, the biofuels digesters create are still a form of gas. They still emit carbon when they’re burned. As such, many environmentalists argue that producing them perpetuates our reliance on gas-powered vehicles, and forestalls a transition to zero-emission electric vehicles, and away from factory farms.
Due to their expense, digesters are only practical for use on the largest factory farms, and they rely on the continued use of manure lagoons, which have a host of negative environmental and social impacts themselves.
Rebecca Wolf, a senior food policy analyst at the nonprofit Food & Water Watch, argues against digesters and biofuels on the grounds that they allow the factory farm system itself to continue chugging along without meaningful reform, while continuing to emit significant amounts of greenhouse gasses.
“They require factory farms to continue to produce large amounts of waste,” Wolf tells Sentient. “And so they’re perfect to put on top of a factory farm, and then keep that waste stream going.”
Digesters, Wolf says, “bring together Big Oil and Big Ag,” as they allow both industries to “greenwash their waste products” while continuing to emit prolific amounts of greenhouse gases.
3. Feed Additives
Feed additives are similar to digesters in that they’re designed to reduce methane emissions on animal farms. But while digesters do this by capturing methane that’s emitted from animal waste, feed additives reduce the amount of methane animals emit in the first place by altering the way their bodies digest food.
Although most feed additives haven’t yet been subject to rigorous testing, one exception is a compound known as 3-NOP. Studies of 3-NOP suggest that it could reduce enteric methane emissions by as much as 32.5 percent.
Feed Additives Aren’t So Practical or Effective
In order to work, animals need to eat feed additives every day; this works for cattle who are fed concentrates, but for those that feed via grazing, ensuring that each of them eat enough additives every day is a logistical nightmare.
Moreover, these additives aren’t cheap. While fighting climate change benefits all of humanity in the long run, buying expensive feed additives doesn’t benefit individual farmers in the short run; it hurts their bottom line, and this is a major obstacle to the widespread adoption of feed additives.
Lastly, because most feed additives haven’t yet been sufficiently studied, it’s unclear what other effects they might have on animals or humans. There’s even some research that 3-NOP, ostensibly one of the most promising feed additives, actually increases carbon dioxide emissions.
“Animal agriculture has a lot of negative environmental impacts,” Ho tells Sentient. “It’s not just the CO2 emissions. If you feed some seaweed to cows, you’re still going to get the other negative environmental impacts. Those aren’t going away, and so it does seem like we should do something that will reduce all of those impacts, not just the CO2 or the methane.”
4. Reducing Meat Consumption
There’s an elephant in the room when we talk about animal agriculture as a driver of climate change: our appetite for animal products. Per-capita meat and dairy consumption have been steadily rising over the decades, and with it, our reliance on factory farms as a food source. Climate “solutions” like feed additives and digesters do nothing to stem this appetite. In fact, they seem to help entrench our current food system even further.
Many climate research groups, like World Resources Institute and Project Drawdown, have pointed out that if global north countries simply ate less meat, especially beef, this would make a huge dent in the climate problem. In practical terms, such a reduction would have to take place primarily in middle- and upper-income countries, which consume a disproportionate amount of meat on a per-capita basis.
“The choice of what people eat matters a lot,” Ho says. “If we stop eating beef and cut down on dairy, or just cut out dairy altogether, that would make a huge difference.”
Cultivated Meat Could Help With Meat Reduction
Ho is optimistic about cultivated meat as a potential climate solution. The prospect of being able to create real meat in a laboratory without needing to clear away land, house, feed and slaughter millions of animals is an incredibly appealing proposition in the fight to bring down carbon emissions and reduce global temperatures.
Cultivated meat technology is still in its infancy, though. As it stands, it’s still much too expensive to scale; this means it can’t be deployed now, which means it doesn’t yet meet Smith’s criteria for a climate solution.
Just as significantly, cultivated meat — and any climate solution that entails people replacing traditional meat in their diet — faces cultural hurdles. Many people, including some powerful elected officials, are skeptical of meat that’s created in a laboratory, and in the U.S., some Republican governors have even signed laws banning its sale within their states.
But Ho is supportive of the technology, which may well become more affordable and practical as future research brings down its production costs.
“I know that some people are not really into cultivated meat, but I would get more excited about that than like, reducing methane emissions from cows,” Ho tells Sentient. “It also deals with the animal suffering part of it, which I think is huge.”
The Bottom Line
There are contentious debates happening around climate action — how much should we invest in technologies, versus fundamentally remaking the way we produce things — especially food. There are deep divides, yet there is also a lot of agreement on simpler strategies, like eating less meat and more beans; a diet that remains healthier for the planet and its inhabitants, animals and people alike.

Electric vehicles in North Carolina and around the country are getting love this week.
A coalition of clean vehicle advocates has declared the week leading up to Valentine's Day EV Love Story week.
The week comes in the midst of the Trump administration's suspension of a $5 billion electric vehicle charging station program.
But that hasn't put a damper on the experience of electric vehicle driver Gene Kelly, who is the energy specialist for Rockingham County Schools in North Carolina.
"Do I want to use the fuel in my other vehicle that I have to pay three to four times more for," said Kelly, "or should I just take my electric vehicle and conserve the fuel in my gas vehicle? It's a no-brainer decision."
More than 81,000 electric vehicles were registered in North Carolina as of September 2024, according to state Department of Transportation data.
In 2022, former Gov. Roy Cooper set a goal of having 1.25 million zero-emission vehicles on the road by 2030.
Kelly said there are many advantages to electric vehicles, including technology that makes them safer.
"Safety and I'm improving the environment of the community that I live in," said Kelly, "because that's where I use my energy."
Even if there are policy shifts on the federal level under President Trump, Kelly said car manufacturers are diving into electric vehicles.
"They've already left the starting line and so there are a lot of options," said Kelly, "and I think that with more options the American consumer can feel very comfortable making a decision to move to electric vehicles."
