Following President Donald Trump's announcement that the U. S. government would withdraw from the Paris climate accord, Bloomberg outlined a coalition of cities, states, universities and businesses that had come together to honor America's commitment under the agreement through 'America's Pledge. ' Bloomberg offered up to $15 million to the UNFCCC, the UN body that assists countries with climate change efforts.  About a month later, Bloomberg and California Governor Jerry Brown announced that the America's Pledge coalition would work to "quantify the actions taken by U. S. states, cities and business to drive down greenhouse gas emissions consistent with the goals of the Paris Agreement. " In announcing the initiative, Bloomberg said "the American government may have pulled out of the Paris agreement, but American society remains committed to it. " Two think tanks, World Resource Institute and the Rocky Mountain Institute, will work with America's Pledge to analyze the work cities, states and businesses do to meet the U. S. commitment to the Paris agreement.
