(CNN) The Trump administration is taking steps toward an anticipated move to roll back greenhouse gas emissions and fuel economy rules for cars, The New York Times reported Thursday.

The newspaper reported that details of the initiative remain in flux, but noted that the plan "could substantially roll back the Obama-era standards," citing two sources familiar with deliberations over the move. An Environmental Protection Agency spokeswoman confirmed to the Times that EPA Administrator Scott Pruitt has given the White House a 16-page draft proposal to review.

Former President Barack Obama made regulatory efforts to fight greenhouse gas emissions -- and climate change -- a central focus of his second term in office. Those efforts were criticized by some Republicans, who characterized the EPA's environmental regulations as government overreach.

President Donald Trump campaigned on promises to cut back on environmental regulation.
