The U.S. Climate Alliance, a bipartisan coalition of governors that support climate action, applauded the new target and pledged to work toward it, with or without help from the White House.

New York Gov. Kathy Hochul, the alliance’s co-chair, said climate-conscious governors “will carry the torch forward” after Biden leaves office. Hochul, a Democrat, said governors will use the new U.S. goal to “keep America on track toward a cleaner, safer future.”

“By continuing to stamp out climate pollution together, we’re safeguarding public health, protecting the environment, growing the economy and creating good jobs across the U.S,” said New Mexico Gov. Michelle Lujan Grisham, another alliance co-chair.

Biden, in his remarks, called the new goal “ambitious” and said it would lead to thousands of well-paying jobs, more affordable energy, cleaner air, cleaner water and a healthier environment for all Americans.

“It is also creating real momentum because we’re unleashing American ingenuity and innovation. And together, we will turn this existential threat into a once-in-a-generation opportunity to transform our nation” for decades to come, Biden said. “I know we can do this.”

The proposal would require sustained changes across the economy, from power generation to transportation, buildings, agriculture and industry, including significant increases in renewable energy such as wind and solar power and steep cuts in emissions from fossil fuels such as oil and coal.

The U.S. pledge includes methane reductions of at least 35% from 2005 levels by 2035, Biden said. Cutting methane emissions is among the fastest ways to reduce near-term warming and is crucial to reducing greenhouse gas emissions.

Debbie Weyl, U.S. acting director of the World Resources Institute, a global research organization, said the new emissions target is “at the lower bound of what the science demands,” but said it was “close to the upper bound of what is realistic if nearly every available policy lever were pulled” in the next decade.

“Assertive action by states and cities will be essential to achieving this goal,” she said, adding that the United States needs to swiftly expand renewable energy and electric vehicles, modernize the electric grid and decarbonize heavy industry.

The nonbinding but symbolically important pledge is a key part of the Paris agreement, which calls for countries to submit so-called Nationally Determined Contributions every five years. A country’s NDC, or climate goal, outlines how it plans to reduce greenhouse gas emissions to help meet the global goal of limiting temperature rise to 1.5 degrees Celsius since pre-industrial times.

The Paris Agreement requires that NDCs are updated every five years with increasingly higher ambition, taking into consideration each country’s capacity. The next deadline is February 2025, although Brazil, the United Kingdom and the United Arab Emirates have already submitted their proposed NDCs.

“As the world’s largest producer of oil, the largest producer and exporter of fossil gas — and the largest historical climate polluter — the United States has an outsized responsibility to press forward in the climate fight no matter the political headwinds,” said Manish Bapna, president and CEO of the Natural Resources Defense Council, a leading environmental group.

He called the new climate goal a clear signal for governors, mayors and CEOs who support climate action to “step up” and defend climate progress.

“While the incoming administration has vowed to turn its back on the world — again — the majority of Americans want climate action, and the clean energy boom is unstoppable,” Bapna said.
