Apple joined Nike, PG&E, EXELON and PNM Resources in resigning from the U.S. Chamber of Commerce, citing lack of urgency of action on climate change.

Catherine A. Novelli, Vice President of Apple's worldwide government affairs, in a letter to the President and CEO of the U.S. Chamber of Commerce, Thomas J. Donahue wrote, "We would prefer that the Chamber take a more progressive stance on this critical issue and play a constructive role in addressing the climate crisis... because the Chamber's position differs so sharply with Apple's, we have decided to resign our membership effective immediately." Apple is the latest in a series of high-profile companies to resign from the U.S. Chamber of Commerce due to disagreements on climate policy. 

Other companies to quit the Chamber for similar reasons include Exelon, PNM Resources and PG&E. Nike has also recently resigned from the chamber's board of directors.
