Royal Dutch Shell vowed last September to reach net-zero carbon pollution in its business by 2050. The goal was vague but notable, and seemed to become more realistic when the corporation announced earlier this month that its crude oil production had peaked in 2019 and would likely never increase again.

While the IPAA does not publish a list of its members, a partial list obtained by the nonprofit Western Values Project in 2018 shows that Shell and other major U.S. oil and gas companies ― including Chesapeake Energy, QEP Resources, Ovintiv and SM Energy ― are all members.
