At the Earth Day 2021 Summit, Canada declared its intent to reduce emissions to 40 to 45 per cent below 2005 levels by 2030.
Key Points:
- At the Earth Day 2021 Summit, Canada declared its intent to reduce emissions to 40 to 45 per cent below 2005 levels by 2030.
- This action is based on the assertion in the United Nations Intergovernmental Panel on Climate Changes (IPCC) 2018 Special Report on 1.5C Warming, which showed such measures would yield net benefits to society.
- It argued that 2C warming would have bigger impacts than 1.5C, but it did not say that the policies to hit the lower target would be worth the cost.
- Research by leading economists, including Nobel laureate William Nordhaus, has shown such policy targets fail standard cost-benefit tests, says Robert P. Murphy, senior fellow at the Fraser Institute and report co-author.
