The bosses of some of the world’s biggest oil companies discussed adopting much more ambitious carbon targets at a closed-door meeting in Davos, a sign of how much pressure they’re under from activists and investors to address climate change.

The meeting, part of a World Economic Forum dominated by climate issues, included a debate on widening the industry’s target to include reductions in emissions from the fuels they sell, not just the greenhouse gases produced by their own operations, people familiar with the matter said on Wednesday.

The talks between the chief executive officers of companies including Royal Dutch Shell Plc, Chevron Corp., Total SA, Saudi Aramco, Equinor ASA and BP Plc showed broad agreement on the need to move toward this broader definition, known as Scope 3, the people said, asking not to be named because the session was closed to the press. The executives didn’t take any final decisions.

Shell declined to comment. Media representatives for Chevron, Total, Aramco and BP weren’t immediately able to respond to requests for comment. Equinor confirmed its CEO Eldar Saetre attended the meeting.
