Brown announced yet another plan Wednesday, July 12, 2017, to keep the United States on track to reduce greenhouse gas emissions under the international Paris climate agreement. This time, he's teaming up with former New York City Mayor Michael Bloomberg to launch "America's Pledge," an initiative to compile all of the climate change-fighting commitments of states, cities, businesses and universities in one place where they can be easily tracked and shared.
