"Trump Repeal of Climate Rules Means US Paris Target Now Out of Reach"

"The U.S. would have had to ramp up its climate ambitions to help slow global warming to the 2 degrees C goal, but under Trump, it's going in the opposite direction."

"Whether the U.S. meets its emissions-reduction commitments under the Paris climate accord is pivotal to the success of the global agreement, but the Trump administration's policies have all but ensured the U.S. will fall far short. One recent analysis says the country will miss its target by more than 1 billion metric tons.

Under President Barack Obama, the United States pledged to reduce greenhouse gas emissions 26-28 percent from 2005 levels by 2025. That means emissions must be cut about 1.7 billion metric tons, according to figures from the Environmental Protection Agency's latest greenhouse gas inventory. The nation is a third of the way to that target, but the rest was to be achieved via an array of regulations, especially the Clean Power Plan, that are now targeted for elimination by President Donald Trump. Not only was the goal dependent on those rules, it would have also required even more rigorous policies from Obama's successor because reductions from those rules would not have been enough, numerous studies have found.

David Bookbinder, a longtime environmental lawyer and a fellow at the libertarian think tank the Niskanen Center, released a new analysis that puts the shortfall at 1 billion metric tons if Trump succeeds in undoing most of the Obama-era climate rules. Meaning, emissions from the world's second-largest carbon polluter would be virtually unchanged from today. That would jeopardize any chance the world has to set a course of deep and rapid decarbonization over the next critical few years."
