BLOOMBERG: "As the 2020 presidential campaign gets underway, I believe every candidate that wants to be president of the United States should put forward a plan for fighting climate change. And I believe every voter should ask the candidates not just what do you promise to do, but also what have you done, what have you delivered, and how can we implement in a practical ways your proposals? There are plenty of leaders in our country who have taken action and are already proving that progress is possible. And I hope we send more of them to Washington in 2020."
