July 30, 2018—A draft proposal by federal regulators would reduce societal costs by roughly half a trillion dollars through 2029, while increasing U.S. fuel consumption by 500,000 barrels per day, reported Time.

The assertions are detailed in an undated draft of the National Highway Traffic Safety Administration and Environmental Protection Agency forthcoming joint proposal to halt higher auto efficiency requirements after 2020, according to the report.

The draft was obtained and published earlier by the New York Times. Sources familiar with the administration’s planning say the document appears to be a version sent to the White House for review in May, and cautioned that its contents could change somewhat by the time it’s released next week, reported Time.
