Major industrial resource projects under provincial jurisdiction that spew massive amounts of carbon emissions will no longer trigger federal environmental assessments — a move that’s angering environmental groups.

The Liberal government walked back the requirement in amendments to its controversial 2019 Impact Assessment Act, parts of which the Supreme Court deemed unconstitutional in the fall.

Environmental groups are raising the alarm and expressing their “disappointment” in a recent letter about the amendments introduced in Parliament on Tuesday.

“We are concerned that the government is not fully living up to its responsibility to protect Canadians and the environment from the climate impacts of major projects across Canada,” says the letter, which was signed by various environmental groups, including the environmental law group Ecojustice.
