Trudeau takes carbon pricing debate to the global stage at COP26

Prime Minister Justin Trudeau pushed the world to have 60 per cent of the world's greenhouse gas emissions covered by a price on pollution in 2030, during a speech at the COP26 climate talks in Glasgow on Tuesday.

Trudeau started his second and final day at the annual climate negotiations by co-hosting a carbon pricing event, showcasing Canada's carbon price as one of the most ambitious and, in his words, stringent in the world.

"What a strong carbon price does, when it's properly designed, is actually drive those price signals to the private sector, transform the economy and support citizens in encouraging them to make better choices," he said.

He started the first day with a speech calling on the rest of the world to follow Canada's lead and negotiate a global minimum carbon price.

Trudeau compared the idea to the 15 per cent minimum corporate tax more than 130 countries have now signed on to implement in a bid to stop big multinational corporations from avoiding taxes by funnelling their profits through low-tax countries.
