There are no easy answers for how to limit global warming to 1.5C, but the IPCC’s research does clarify the options. In short, what is clear is that Canada and other countries need to implement much higher carbon taxes, and fossil-fuel-producing jurisdictions like Alberta need to develop and legislate plans for phasing out hydrocarbon production over the next number of years. In the case of the oil sands, this most certainly means phasing out production by 2050, and every year that timeline can be shortened gives humanity more of a chance to limit global warming to 1.5C.
Despite this reality, the Big Five all forecast an increase in total emissions in the future due to their plans to increase bitumen production.
