Prime Minister Justin Trudeau joined world leaders Friday to help formally ratify a global treaty on climate change.
Putting his signature to the Paris accord was the easy part. The hard part comes next: reducing Canada’s greenhouse-gas emissions by 30 per cent over the coming decades.
Canada is nowhere near that target – emissions continue to rise, and a national plan has yet to be worked out.
“Today, with my signature, I give you our word that Canada’s efforts will not cease,” Trudeau told the UN’s General Assembly hall, with dozens of other leaders seated in the crowd.
The agreement enters into force once it’s signed by 55 countries accounting for 55 per cent of global emissions, a threshold it appeared to have clearly surpassed Friday.
The new pact differs from the old Kyoto accord in several important ways:
- Every major emitter has set individual targets under this one – unlike Kyoto which included fast-developing countries.
- It does not include broad global emissions targets, nor is it binding.
- It does include a mechanism that will report on each country’s progress.
The broad goal of the agreement is to keep global temperatures from rising less than 2 C from pre-industrial levels, in an effort to stave off the most catastrophic effects of rising sea levels.
His New York trip concludes today with a meeting with Colombia’s president and a press conference.
The Conservatives said he hasn’t been straight with people. They pointed to the parliamentary budget officer’s finding that hitting that target could shave one to three per cent off the national economy by 2030.
“The Liberals are misleading Canadians by saying everything is a win-win, while not accounting for the true economic costs,” said a statement from critic Ed Fast.
“Fighting climate change is serious business and Canadians need to be prepared to have a frank discussion about who pays for it.”
The Conservatives said they’re not actually opposing the emissions target – which they set when they were in power. They just said the prime minister needs to be more honest about the costs.
