Shell says it plans to leave the American Legislative Exchange Council (ALEC), an influential political group that advocates against climate policies.
The company said ALEC’s stance on climate change is “clearly inconsistent with our own”.
The UK-Dutch oil giant said it would leave the Washington-based organisation when its membership expires in early 2016, as part of an “ongoing review of memberships and affiliations”.
“We have long recognized both the importance of the climate challenge and the critical role energy has in determining quality of life for people across the world,” the statement added.
Shell’s decision follows that of BP in March this year, and comes off the back of a campaign by the US Union of Concerned Scientists against its continued membership.
Google, Facebook and Yahoo quit the group in the past year.
Critics of ALEC say the group actively promotes the denial of man’s influence on climate change.
