A new analysis found Utah oil and gas companies waste an estimated $48 million worth of natural gas per year, enough to meet the annual needs of more than a fifth of residential customers in Utah, according to the Environmental Defense Fund.

The large majority of the gas, 87%, is lost due to leakage from producers.

Ashley Miller, executive director of the nonprofit Breathe Utah, said leakage needs to be addressed to ensure better air quality and protect the overall health of Utahns and the environment.

"Getting a handle on leaks from oil and gas; I really do feel like that is pretty close to low-hanging fruit that is left to do," Miller contended. "There is technology available that, you know, this isn't new stuff. For the most part we aren't talking about huge capital infrastructure projects."

Miller recognized it likely will not be an easy fix, especially for smaller operations but stressed it is necessary. She urged stakeholders to look at the financial, health and environmental consequences of not addressing the issue. The analysis found in 2019, the state of Utah lost about $6.7 million dollars in tax and royalty revenue, including more than $1.2 million in lost revenue for the tribal governments in the state.

The Environmental Protection Agency is set to finalize a proposed rule this fall to address methane pollution.

Miller pointed out while national guidance and regulation can help all states around the country, she encouraged Utah policymakers to find ways to build on the rule with Utah specifics in mind.

"If you take something where this will actually move the needle in terms of air pollution, public health, economy, climate; all of these things, you couldn't pick a better recipe for progress," Miller asserted.

The analysis called for "strong, common-sense rules" to cut methane waste and pollution which will not only help slow the rate of climate change, but will also protect public health, create jobs, generate additional tax revenue and prevent the needless waste of energy sources.

As Cleveland tightens its air quality standards for the first time since 1977, health officials are urging residents to take simple steps at home to reduce their exposure to harmful pollutants.

The Environmental Protection Agency reported Americans spend about 90% of their time indoors, where air pollution levels can be two to five times higher than outdoor air.

Richard Stewart, public information officer of the Department of Public Health for the City of Cleveland, said the city's push is part of its efforts to engage local residents with new monitoring tools and resources through its "CLEANinCLE" initiative.

"A lot of folks don't realize small changes inside the home can really improve your quality of life," Stewart pointed out. "For example, taking your shoes off before you come in the house, checking for lead paint dust, cracking windows. Just regular cleaning can make a big difference in improved air quality in your house."

CLEANinCLE is a community air monitoring project, including sensors in multiple neighborhoods. The health department hosts two public meetings this week, one Wednesday from 6 p.m. to 7:30 p.m. at the Frederick Douglass Recreation Center and another on Thursday at the Community of Faith Assembly. Both events include free in-home air assessments and raffles for air purifiers and electric stoves.

While many cities face water-related lead risks, Stewart noted one of Cleveland's biggest concerns is still old paint. Officials are asking residents to look out for cracking or peeling paint surfaces, especially in older housing and report issues which could expose children to lead.

"There's no amount of lead that's acceptable in a child's bloodstream," Stewart emphasized. "If you see that 'alligator paint,' where it's cracking and kind of fizzling on the house, contact your landlord. And if you're not getting any results, contact us."

The city also has a Lead Hazard Control Grant Program to help eligible property owners remove lead paint.

A new study shows trees in mid-city Los Angeles absorb up to 60% of carbon dioxide emissions during spring and summer when the trees are most active.

In 2021, researchers from the University of Southern California placed 12 sensors in central L.A. to monitor carbon dioxide levels.

Will Berelson, professor of earth sciences, environmental studies and spatial sciences at the University of Southern California-Dornsife, said trees are surprisingly effective at lowering carbon dioxide levels in the air.

"The input of CO2 from cars is predicted to be a certain level," Berelson explained. "But when we look for CO2, we find much less. This difference is due to uptake of CO2 by trees."

Berelson pointed out emissions are like passengers on a train, as wind moves pollution through the city, where some get picked up and dropped off. The sensors measure the pollution in real time. The research published in the journal Environmental Science and Technology found trees absorb about 30% of carbon dioxide, averaged over 24-hour periods over a year. So clean energy, improved public transit and broader emissions reductions are still needed.

Berelson noted the sensors, called a Carbon Census Array, will track carbon dioxide levels for years to come.

"The City of L.A. is always committed to reducing emissions and it isn't clear how they're going to keep track of whether their emissions have actually lowered or not," Berelson observed. "But we've got a way to now track emissions and quantify emissions."

The sensor network is now being expanded, with 12 additional sensors reaching out to Santa Monica on the west side of the city.

The negative effects on air quality from industrialized animal facilities in North Carolina stick around for a long time, according to a new study.

The research showed the effects are felt most by communities of color.

Sally Pusede, associate professor of environmental science at the University of Virginia and lead author of the study, said her team used satellite measurements of ammonia pollution associated with industrialized swine operations in eastern North Carolina.

"Those ammonia air quality impacts are disproportionately experienced by residents in eastern North Carolina who are Black and African American, Hispanic and Latino, and Indigenous," Pusede reported.

Compared to white communities, the study found ammonia concentrations were 27% higher for Black communities, 35% higher for Hispanic communities and 49% higher for indigenous communities between 2016 and 2021. Pusede noted satellite data from 2008 to 2013 showed the trends have largely remained unchanged.

Weather conditions can also increase the effects of ammonia pollution, with warm conditions and calm winds amplifying disparities. Pusede pointed out contrary to claims industrial swine operations only affect nearby communities, ammonia in warm conditions can travel quite far.

"Ammonia is emitted into the atmosphere, it travels downwind and then eventually that ammonia will deposit," Pusede explained. "The next day when the sun comes up, the air temperature warms, that ammonia can be reevaporated or revolatized into the atmosphere, and then can be transported even further downwind."

Pusede added broadly speaking, there are no protections from the air quality effects of industrial agriculture, not just ammonia but other pollutants as well.

"In North Carolina, there's a history of people not being protected by the state regulatory agencies," Pusede observed. "There's also not been regulations at the federal level from the EPA, and so that's a problem."
