President Joe Biden invited world leaders to join the U.S. in driving a “fourth industrial revolution” to transform the energy sector, create jobs and overcome the threat of climate change, capping his two-day summit on global warming April 23.

The American Petroleum Institute board voted March 25 to endorse putting a tax or other price on carbon dioxide emissions, a shift for the oil industry that could influence the Biden administration’s plans for a governmentwide assault on global warming.

The Biden administration is revoking dozens of invalid drilling permits issued by agency workers without the approval of political appointees, despite a temporary order for such reviews.

Environmentalists and Alaska natives are challenging the Trump administration’s decision to sell drilling rights in the Arctic National Wildlife Refuge, arguing the government gave short shrift to the impact on polar bears and the region’s other wildlife.

The Environmental Protection Agency notified California in a letter Sept. 24 that it has failed to file complete plans for fighting conventional air pollution and may lose highway funding as punishment.

The Trump administration is seeking to abandon regulations designed to stop methane leaks from oil and gas wells, a move opposed not just by environmentalists but even some energy companies that worry that it will undermine the appeal of natural gas as climate-friendly fuel.
