President-elect signals intent to undo Obama efforts at curbing greenhouse emissions

Donald Trump has signalled his intent to undo Barack Obama’s efforts to curb climate change by choosing as his chief environmental regulator a conservative state law enforcer who is currently battling to overturn the president’s legacy.  Scott Pruitt, Oklahoma’s attorney-general, has been selected to lead the Environmental Protection Agency, as the president-elect turns to a man who, like himself, has questioned the science of climate change, the Trump team said. If confirmed by the Senate he would be catapulted from the US’s oil-producing heartland to the centre of global policymaking on climate change, a position from which green groups worry he would wreck progress to stem carbon emissions.  Mr Pruitt, 48, has railed against the EPA for meddling in state affairs and played a leading role in a lawsuit that has frozen the centrepiece of Mr Obama’s climate policy pending a court judgment.  His nomination sparked a fierce reaction from the left. Senator Jeff Merkley said he would turn the EPA into the “Polluter Protection Agency” and Eric Schneiderman, New York attorney-general, called him a “dangerous and unqualified choice”.
