WASHINGTON — The Biden administration proposed June 15 that future planes produce lower levels of greenhouse gas emissions before they can be certified by federal regulators.

California’s carbon market was supposed to be a model for the U.S., harnessing the power of capitalism to fight climate change in the world’s fifth-biggest economy. But nearly 10 years after “cap and trade” began, there’s little proof the system has had much direct impact on curbing planet-warming pollutants.

Companies will need to reveal detailed information about their greenhouse gas pollution under a proposed U.S. Securities and Exchange Commission plan, marking a major shift in how corporations must show they are dealing with climate change.

The Biden administration plans to announce new limits on greenhouse gas auto emissions and new electric-vehicle sales targets at an event with Detroit automakers at the White House on Aug. 5, according to several people familiar with the matter.

A leading private carrier and a tier one supplier recently each announced additional sustainability goals.

The House voted June 25 to rescind a Trump-era rule blocking the Environmental Protection Agency from directly limiting oil industry emissions of the powerful greenhouse gas methane, a move that would restore requirements imposed by the Obama administration while freeing the agency to craft new more stringent rules for the oil and gas industry.

Agriculture giant Cargill Inc. will start selling methane-absorbing wearable devices for cows, putting its support behind an experimental technology that could help the industry cut greenhouse gas emissions.

The Biden administration on April 26 took a key step toward restoring California’s power to limit greenhouse gas emissions from vehicles and overturn a Trump-era policy that pitted the federal government against a state seeking to eventually ban conventional gas-powered cars.

More than a year ago, U.S. Environmental Protection Agency officials announced the agency’s Cleaner Trucks Initiative, an effort to work closely with the California Air Resources Board to develop a more stringent “harmonized” nitrogen oxide-emissions rule for heavy trucks.

A new study by the National Academy of Sciences urges federal regulators to conduct an “interim evaluation” of the federal medium- and heavy-duty truck Phase 2 greenhouse gas and economy rule with an eye toward more stringent standards.
