Democratic presidential nominee Joe Biden on Wednesday vowed to bar from his transition team any \u0022leaders\u0022 of fossil fuel companies, a pledge environmentalists cautiously applauded while urging the former vice president to go further by committing to banning all Big Oil lobbyists and executives from both his transition team and cabinet.\u0022Rejecting fossil fuel influence is a smart move for the Biden-Harris campaign,\u0022 Charlie Jiang, climate campaigner with Greenpeace USA, said in a statement Thursday. \u0022Voters are hungry to elect a climate champion. Joe Biden is running on the most ambitious climate platform in history, but it won\u0026#039;t mean much if his transition team is stacked with oil and gas insiders.\u0022\u0022Voters are hungry to elect a climate champion. Joe Biden is running on the most ambitious climate platform in history, but it won\u0026#039;t mean much if his transition team is stacked with oil and gas insiders.\u0022 —Charlie Jiang, GreenpeaceIn a document titled \u0022Biden-Harris Transition Team Ethics Plan\u0022 (pdf), the campaign states that \u0022in addition to instituting a robust code of ethical conduct, Vice President Biden aims to ensure that those who serve are aligned with his values and policy priorities, and have not, for example, been leaders at fossil fuel or private prison companies.\u0022But the ethics plan falls well short of adhering to a list of demands issued last month by a coalition of nearly 150 climate organizations, which urged Biden to \u0022ban all fossil fuel executives, lobbyists, and representatives from any advisory or official position on your campaign, transition team, cabinet, and administration\u0022 if elected president.While the Biden campaign will require transition team members to sign a pledge promising to disqualify themselves from \u0022involvement in any particular Biden-Harris transition team matter\u0022 if they have \u0022engaged in regulated lobbying activities with respect to such matter\u0022 within the previous 12 months, the requirement comes with a substantial loophole.\u0022Persons who have registered as federal lobbyists within the last 12 months may only serve as transition team members with advance approval of the General Counsel,\u0022 the document states, suggesting that lobbyists for the fossil fuel industry could ultimately be permitted to serve on the transition team..@JoeBiden is making a smart move by asserting that he won\u0026#039;t allow fossil fuel execs on his transition team. He should take it a step further and ban them from his cabinet and administration altogether. https://t.co/io8O2rpUDhw/ @charlieyj12 #Climate2020— Ryan Schleeter (@Ryschlee) October 1, 2020Jiang said that while the Biden campaign\u0026#039;s ethics plan \u0022is a strong start,\u0022 it \u0022is not the end of the road.\u0022\u0022We urge Biden to commit to banning all fossil fuel executives and lobbyists from his cabinet and administration,\u0022 Jiang added. \u0022Personnel is policy, and we need experts in the White House who put climate and environmental justice ahead of corporate profits.\u0022On Twitter, Collin Rees, senior campaigner at Oil Change U.S., called Biden\u0026#039;s move \u0022a key first step\u0022 made possible by constant pressure from grassroots climate activists.\u0022Committing to a fossil-free transition team is exactly what we need to see heading into a new administration with climate impacts mounting rapidly,\u0022 Rees added in a statement Thursday. \u0022Keeping fossil fuel representatives out of the federal government is a position that\u0026#039;s extremely popular with Democrats and the entire American public, and builds on the key improvements Biden has made to his climate plan since the primary. The Biden-Harris campaign is clearly listening to its potential allies, and this willingness to listen and adapt will be critical in the months ahead.\u0022This article has been updated with additional comment from Oil Change U.S.
