The Paris Agreement's long-term temperature goal is to keep the increase in global average temperature to well below 2 °C above pre-industrial levels; and to pursue efforts to limit the increase to 1.5 °C. This requires countries to cut emissions by 45% by 2030, end fossil fuel subsidies and ban new coal plants after 2020. Most of our parties talk about "reducing" carbon emissions but do not set goals to cut emissions by 45% by 2030.
The Conservative Party climate plan has been almost universally panned by experts for failing to have any reasonable chance of achieving the weak 2030 emissions targets the Harper government set. It is as good as no plan, which is a plan to fail.
Although better than the Cons, the Liberal climate plan is to reduce our emissions by 30% by 2030, compared to 2005 levels. This falls way short and is a plan to fail.
The NDP talk about achieving targets in line with scientific consensus. This definitely sounds better than the Liberals but they support new fossil fuel projects which will make achieving the goal impossible.
The Green Party has the most aggressive plan which clearly heeds the UN’s call for rapid and transformative changes to Canadian society. The plan has faced criticisms for being unrealistic in scope and speed, but there is broad consensus that it would exceed emissions targets if implemented.
If you still don't understand, ask 16 year old Greta Thurman to explain. She gets it.
