Ontario's Emission Reduction Targets
Ontario’s share of the global carbon budget can be calculated based on various sharing strategies: the main ones are:
- percentage of the global population (Ontario's share of the global population is 0.19%).
- annual emissions (Ontario's share of global emissions is 0.39%)
- percentage of Canada's emissions (Ontario's share of global emissions is 23%)
If Ontario reduces their annual emissions after 2017 by approximately 10 MtCO2e each year the target emissions reductions would be as follows:
- 2020 30%
- 2025 65%
- 2030 100%
If we do this, Ontario will have achieved zero carbon emissions before 2032 and not exceeded our fair share of the global carbon budget for a keeping the temperature increase around 2 degrees C.
