Nancy Pelosi championed climate as House Democrats' leader

"After becoming the first woman speaker in 2007, she set up the Select Committee on Energy Independence and Global Warming in the face of criticism from committee chairs who saw it as encroaching on their turf. Republicans didn't renew the committee after recapturing the majority in 2010. But when Democrats regained House control in 2018, Pelosi resurrected it as the Select Committee on the Climate Crisis, only to have the GOP disband it in 2023."

"Also in 2007, she steered into law an energy bill that raised vehicle fuel efficiency standards for the first time in three decades. Under President Barack Obama, she got the House to pass a bill that would set up a cap-and-trade system for greenhouse gas emissions. But the highly controversial measure never advanced in the Senate, and was seen as a political albatross for at least some of the more than 50 House Democrats who lost their seats in 2010."

"The Pelosi-led House in 2009 also passed the American Recovery and Reinvestment Act, which included $69 billion in clean energy funding. Zoom in: When President Trump first took office in 2017, Pelosi became one of his chief critics. She pushed through a bill in 2019 requiring the United States to remain in the Paris Agreement - from which Trump withdrew the U.S. - and led a delegation to the COP25 summit in Madrid to reiterate commitment to the pact."

Nancy Pelosi elevated climate policy as a central priority throughout her tenure in House leadership. She created and later resurrected select committees on energy independence and the climate crisis, despite Republican disbanding. She steered a 2007 energy bill raising vehicle fuel efficiency standards and led the House to pass a cap-and-trade bill under President Obama, though it stalled in the Senate. The Pelosi-led House approved $69 billion for clean energy in the 2009 recovery act. Pelosi pushed measures to keep the U.S. in the Paris Agreement, led a COP25 delegation, and helped pass bipartisan infrastructure investments that contributed to later enactment of the Inflation Reduction Act.
