Two founding members of the federal government’s Net-Zero Advisory Body have resigned, saying its work is being ignored by Ottawa as it moves away from previous climate commitments and toward new oil and gas projects.

University of British Columbia professor Simon Donner and global climate campaigner Catherine Abreu both resigned from the group this week, leaving the advisory body with just four remaining members.

In a post on his LinkedIn account, Donner says he is grateful for the opportunity to help shape climate policy in Canada. Donner is a prominent climate scientist and was the co-chair of the body.
