NEW YORK — A long-delayed report from the Environmental Protection Agency finds that requiring ethanol made from corn and soybeans to be part of the nation's gas supply is causing serious environmental harm.

Federal law requires the EPA to assess the environmental impact of the fuel standard every three years, but the new report, issued in July, was four years overdue. According to David DeGennaro with the National Wildlife Federation, the report documents millions of acres of wildlife habitat lost to ethanol crop production, increased nutrient pollution in waterways and air emissions and side effects worse than the gasoline the ethanol is replacing.

"In finding that the Renewable Fuel Standard is having negative consequences to a whole suite of environmental indicators,” DeGennaro said, “the report is a red flag warning us that we need to reconsider the mandate's scope and its focus on first-generation fuels made from food crops.”

President Donald Trump and senators from agricultural states are urging the EPA to allow an increase in the mandated ethanol content of gasoline.

The EPA report indicates that biofuels have a negative impact on air quality. Johnathan Lewis, senior counsel for climate policy with the Clean Air Task Force, said ethanol from corn in particular is linked to increased emissions of nitrogen oxides, or nox.

"Nox contributes to ozone formation when it mixes with volatile organic compounds in the presence of sunlight,” Lewis said. “So in most areas of the country, an increase in nox emissions can result in increased ozone formation."

Ground-level ozone, the main ingredient of smog, is a major cause of asthma and other respiratory illness.

Right now, most gas is E-10, containing 10 percent ethanol. But despite the EPA report's findings, DeGenarro pointed out there is political pressure to raise the biofuels mandate of the Renewable Fuel Standard.

"Just last week, President Trump told an audience in Iowa that he was "very close" to having EPA issue a waiver to the Clean Air Act to allow year-round sale of E-15,” DeGenarro said.

In March, a bill called the GREENER Fuels Act was introduced in Congress to reduce the use of corn ethanol and cap the content in gasoline at less than 10 percent.

As wildfire seasons in Colorado and across the American West become longer, less predictable and increasingly destructive, a new report aims to provide an equitable roadmap for protecting communities, watersheds and wildlife.

Rob Addington, Colorado forest program director for The Nature Conservancy, said engagement with tribal nations, who have been successful stewards of lands for thousands of years, will be critical to address the scale of the challenge.

"Developing tribal partnerships and really looking to tribal knowledge, ecological knowledge that many of the tribes hold from their centuries in many cases of working with the land, working with fire," Addington outlined.

Addington pointed out the roadmap represents a paradigm shift in modern forest and wildfire management. After decades of fire prevention strategies, for example, experts said prescribed burns will be necessary to thin fuel supplies across thousands of acres of dry western lands. The report also called for advanced computer modeling and unmanned drones to improve early detection, help battle fires more effectively, and to reseed and restore scarred forests.

The roadmap, created by The Aspen Institute and The Nature Conservancy, compiled input from more than 250 experts in forest and fire management, federal, state, local, and Tribal Nation authorities, and the private sector, including the forest products and insurance industries.

Addington noted many of the report's recommendations are shovel-ready, due to recent public investments such as the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act.

"But what we need in parallel to complement that funding is this set of policy recommendations," Addington urged. "To really make best use of that funding, and have it hit the ground in the most efficient and effective way that we can."

Addington underscored building successful partnerships will be key for work that needs to happen in metropolitan areas and across tribal, federal, state and privately owned lands. The report also identified some potential roadblocks, and offered policy solutions requiring action from Congress, the executive branch, and partners like states, Tribal Nations, nonprofits, and industry.

Climate-change groups are calling attention to the environmental destruction linked to the wood pellet industry - even as California is considering a proposal to build two plants. The U.S. is the biggest wood pellet exporter in the world - mostly to Europe.

Laura Haight, U.S. policy director for the Partnership for Policy Integrity, wants the European Union and the U.K. to change their policies.

"In Europe, they treat burning wood as renewable energy and heavily subsidize it. And they're importing massive quantities of wood pellets to fuel their power plants," she said. "And a lot of that is coming from the United States. That's where a lot of our forest destruction is happening. "

More than 100 groups recently wrote
to European Union leaders asking them to prohibit subsidies for wood that comes from living trees. Wood pellet companies claim they only use waste wood from logging or dead wood in the forest that fuels wildfire. But investigations have produced proof that companies have clear-cut forests in the southeastern U.S.

Haight added that burning wood for energy is terrible for the climate.

"There's a large release of carbon dioxide emissions into the air when you burn it. And at the same time, you're removing the tree that is helping us lock in our carbon and so you're both increasing emissions and reducing our capacity to store carbon," she said.

Two wood pellet plants -- the first of their kind in California -- are proposed for Lassen and Tuolumne counties. The plants would be built by Golden State Natural Resources, a public benefit corporation whose board members are local county officials.

Elly Pepper, deputy director of international wildlife conservation for the Natural Resources Defense Council, opposes the projects.

"It would be bad for the air, bad for the wildlife and lands, bad for the communities. And it would be basically California assenting to bioenergy as a renewable energy source when it's most definitely not," Pepper said.

The company did not respond to a request for comment but says on its website that the plants would quote "procure and process sustainably sourced excess forest vegetation into a pelletized renewable fuel source to replace the use of coal."

Thousands of lives are cut short every year because of air pollution from coal-fired power plants in Wyoming and across the United States, according to a new Sierra Club report.

Rob Joyce, energy organizer for the Wyoming chapter of the Sierra Club, said harmful toxins released from burning coal have been linked to a number of health issues, including increased asthma attacks and acute bronchitis, and in severe cases can contribute to an increase in heart attacks and premature deaths over time.

"The report also shows that while those living closest to the coal plants typically bear the worst impacts, once those pollutants are in the air they can travel long distances, and impact communities hundreds of miles away," Joyce explained.

Researchers found pollution from America's coal-fired power plants is responsible for 3,800 premature deaths a year.

The report listed PacifiCorp's Jim Bridger facility, operating since the 1970s in southwest Wyoming, as among the nation's most deadly. PacifiCorp has said it will continue operating two of the site's four units at lower capacities to reduce pollution levels, until they are converted to natural gas as early as this year. The other two units will go offline in 2037.

Joyce acknowledged while the transition away from coal-fired electricity will be good for public health, it added economic uncertainty to communities and state agencies deeply tied to the old fossil fuel economy.

"We need to be creative in our approach to prepare for these changes so that families can sustain themselves," Joyce stated. "And also so that the land, water and wildlife that everyone in Wyoming really values can continue to be enjoyed by everyone."

Just 18% of premature deaths from coal occur in the state where the power plants are located, and Wyoming is among the nation's top five exporters of coal-fired air pollution. Joyce added the report exposes just how dangerous the continued use of coal is for communities, public health and the climate crisis.

"The bottom line is that a transition to clean, renewable energy is not only good for combating climate change, but it will also immediately improve public health and save lives," Joyce contended.
