“The federal carbon pollution price will start low at $20 per ton in 2019, rising at $10 per ton per year until reaching $50 per ton in 2022. The carbon tax will stay at that level unless the legislation is revisited and revised. This is a somewhat modest carbon tax – after all, the social cost of carbon is many times higher – but it’s a higher carbon price than has been implemented in most countries. Moreover, a carbon tax doesn’t necessarily have to reflect the social cost of carbon. The question is whether it will be sufficiently high to meet the country’s climate targets.”
