WASHINGTON (Reuters) - Green groups are split over whether President Joe Biden should step aside for another Democrat in the U.S. election, with some concerned his weakening polling against fossil fuel booster Donald Trump could hamper turnout and jeopardize his climate wins.
Biden, 81, is under pressure and scrutiny from some lawmakers, donors and activists to drop his reelection campaign in the wake of a disastrous presidential debate performance this month that renewed questions about his mental fitness.
Environmental groups are anxious at a potential second Trump administration, after his 2017-2021 term brought sweeping roll-backs of environmental regulation and restrictions on oil drilling, plus withdrawal from an international pact.
A second Trump presidency would almost certainly seek to erase many of Biden's climate policy wins, including rolling back major vehicle and power plant rules and repealing or weakening key parts of the current administration's signature climate law the Inflation Reduction Act, according to his campaign speeches and policy agenda.
Of eight national environmental groups contacted by Reuters, two want Biden to step aside, one wants him to stay, and the rest were undecided or declined to comment.
"Joe Biden's inability to campaign coherently and articulate an alternative to the far right will result in lower turnout among potential Democratic voters faced with a choice between two old white men clinging to power," said Evan Drukker-Schardl, an organizer with Climate Defiance.
DAMPENING TURNOUT
Climate Defiance, which has disrupted events featuring Democratic and Republican officials and lawmakers to protest against weak climate policies and fossil fuel production, plans to blockade Democratic National Committee headquarters on Friday as they schedule a roll call vote to nominate their presidential slate.
Youth climate group the Sunrise Movement, meanwhile, has called for Biden to "pass the torch".
"After speaking with young people across the country over the past few weeks, I am concerned that Joe Biden isn't positioned to mobilize young people and win in November," Sunrise director Aru Shiney-Ajay said.
Friends of the Earth Action said it welcomed "the public discourse surrounding Biden's electability" and was still weighing an endorsement.
Meanwhile, the Sierra Club last week said it would stick with Biden. “No president in history has taken more action on climate than Joe Biden," said its president Ben Jealous. "We will work tirelessly to re-elect President Biden come November."
Natural Resources Defense Council Action declined to comment, while the League of Conservation Voters and EDF (EPA:EDF) Action did not respond to requests for comment.
Third Act, an organization of older people and retirees led by climate activist Bill McKibben, which was influential in urging Biden to halt LNG exports, has also not taken a position. McKibben did not respond for a request for comment.
