President Trump announced at a campaign rally in Iowa that he would lift the ban on summertime sales of a 15 percent blend of ethanol, expected to increase smog levels. Both environmentalists and the oil industry oppose the action.
On Thursday, the U.S. DOT and U.S. EPA announced one of the Trump administration's most consequential rollbacks of environmental and efficiency regulations that will have a detrimental effect on climate change, air pollution, and oil consumption.
New York Times climate reporter, Brad Plumer, comments on California's landmark accomplishment in reducing emissions, observing that with the low-hanging electricity generation fruit picked, reducing transportation emissions will prove formidable.
Normally having the California Air Resources Board and the auto industry in agreement on emissions standards would be enough, but the Trump administration wants to ensure that California plays no role in setting standards.
Environmental Protection Agency Administrator Scott Pruitt had announced the rollback of greenhouse gas emission and fuel economy standards on April 2. While the auto industry supports the move, not all auto executives agreed.
At stake are greenhouse gas emission standards for 2022-25 model year passenger vehicles. Relaxing these standards would likely doom efforts to reduce these emissions 40 percent below 1990 levels by 2030 as required by 2016 state legislation.
While premature to claim victory, a report from the San Francisco Chronicle suggests that the California Air Resources Board will prevail in a looming showdown with the U.S. EPA over whether to allow the state to set vehicle emission standards.
