Now that the U.S. has officially affirmed its international pledge to combat climate change by slashing greenhouse gas emissions by up to 28 percent by 2025, the White House is looking to the next step— getting everyone else on board.
While the pledge itself is about domestic emissions, U.S. officials know that a global deal is toothless without other governments on board, and so the rhetoric has turned abroad.
And Obama has made climate change one of the centerpieces of both domestic and foreign policy in his second term—helping to bring about a final agreement at the United Nations talks in Paris this year would be a monumental capper. Getting international participation is also crucial to selling the the climate plan at home.
The White House hasn't been shy about heaping attention on governments who sign on—or its role in getting them on board.
When Mexico on Friday announced its pledge to peak carbon emissions by 2026, the White House came out with a statement commending the country for setting an "example for the rest of the world," along with a separate joint statement reaffirming a commitment to "jointly addressing climate in their integrated economy."
Most major countries—including major emitters like China and India—hadn't filed official climate plans. Negotiators aren't sweating the rollout, since countries accounting for more than 50 percent of global emissions have made public commitments, but the White House says it's going to keep working with countries until the ink is dry on a deal.
