In response to the following week`s withdrawal, the governors of California, New York and Washington created the U.S. Climate Alliance and promised to keep the Paris Agreement within their borders. [74] [75] On the evening of June 1, 2017, Colorado, Connecticut, Hawaii, Oregon, Massachusetts, Rhode Island, Vermont and Virginia announced their intention to achieve the goals of the Paris Agreement with members of the United States Climate Alliance. Governors of other states have also expressed interest in complying with the agreement. [76] [77] [78] As of November 2020, the Alliance had 24 states, as well as Puerto Rico and American Samoa. [79] [80] Former President Bill Clinton wrote: “To depart from the Treaty of Paris is a mistake. Climate change is real. We owe our children more. Protecting our future also creates more jobs. [59] Former President Barack Obama said of Trump`s decision: “Even if this administration joins a small handful of nations that refuse the future, I am confident that our states, cities, and businesses will rise up and do even more to lead the way and help protect the only planet we have for future generations. [70] Former Vice President Joe Biden said he believed the move affected U.S. security. [71] Many major auto and air carriers had already invested billions in reducing emissions and would probably not change course.

General Motors, the largest automaker in the United States, immediately stated, “Our position on climate change has not changed. we are publicly committed to the fight against climate change” and reaffirmed its support for various climate commitments. Analyst Rebecca Lindland also said automakers were not subject to any specific restrictions under the deal and nothing had changed. Even if Trump eased other restrictions on the auto industry, which allowed for the production of less environmentally friendly cars, those cars still had to meet the standards before being exported to other continents, or even some states. Jason Bordoff, an energy policy expert at Columbia University, agreed that a withdrawal would make no difference to the economy, arguing that it would be determined by market conditions like the price of oil and gas.
