Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
None of Canada's past climate targets or plans has been credible. But the math on the latest plan, which relies on a steadily increasing carbon price, could have Canada meet its 2030 goal.
The Paris Agreement set countries on a path to limit global warming. Five years on, some progress has been made, but not enough. Decarbonizing the economy will take leadership and imagination.
If Canada began to reduce its greenhouse gas emissions by about four per cent per year, we could still meet our 2030 climate targets.
Canada is already behind on tackling climate change and catching up will be expensive, but relying on carbon capture technologies is risky and expensive.
