After Canada elected Mark Carney as prime minister, there was hope that the country would continue to back climate policies. That hope has now been crushed, after Carney signed a deal with the oil-producing province of Alberta that promises to roll back or dilute many green regulations. As a result, Steven Guilbeault, Carney’s culture minister has resigned from cabinet. He was the environment minister under Justin Trudeau and responsible for many of the policies at risk of being undone. This week on Zero, Guilbeault tells Akshat Rathi why the Alberta deal was the last straw and why he thinks the Canadian government should admit that it's set to miss its climate goals.
