"CALGARY, Alberta/OTTAWA - Canada’s Supreme Court ruled in favour of the federal government’s carbon pricing policy on Thursday, upholding a central pillar of Prime Minister Justin’s Trudeau’s climate plan and infuriating some provinces that opposed it.

The country’s top court said climate change is a threat to Canada a whole and upheld the legality of the Greenhouse Gas Pollution Pricing Act, which had been challenged by Alberta, Saskatchewan and Ontario.

Carbon pricing, often called a carbon tax by opponents, is the lynchpin of the federal government’s plan to ultimately reach net-zero emissions by 2050. Ottawa will steadily ramp up the price of carbon to C$170 ($135.08) a ton by 2030, from C$30 a ton currently.

Canada is the fourth-largest oil producer in the world and the fifth-largest greenhouse gas emitter on a per capita basis."
