CGS's recent report examines how new climate policies will impact Canada's future climate action, looking at 5 climate policy scenarios to analyze current progress and ways to get on track to reach net-zero by 2050: go.umd.edu/Canada203...
A view of a crystal blue lake surrounded by forests and snow-capped mountains. Text on the left reads, "Achieving a High Ambition Pathway for Canada’s 2035 NDC and 2050 Net-Zero Emissions Targets; The Center for Global Sustainability’s new report explores how new policy priorities, including the Building Canada Act, could affect Canada’s climate future as the deadline for 2035 NDCs approaches. Through analyzing five climate-policy scenarios with varying levels of climate ambition, the report highlights that Canada's current policies will not be enough to put Canada on track to achieve its climate targets, including net-zero by 2050, and that more policy action is needed."
