Climate change in Canada

Climate change in Canada has had large impacts on the country's environment and landscapes. These events are likely to become even more frequent and severe in the future due to the continued release of greenhouse gases into the atmosphere. The number of climate change–related events, such as the 2021 British Columbia Floods and an increasing number of forest fires, has become an increasing concern over time. Canada's annual average temperature over land has warmed by 1.7 degrees Celsius since 1948. The rate of warming is even higher in Canada's north, the Prairies, and northern British Columbia. The country's precipitation has increased in recent years and extreme weather events have become more common.

Canada is currently the world's 10th largest greenhouse gas emitter, and has a long history of producing industrial emissions going back to the late 19th century. In 2019 transport and oil and gas extraction together emitted over half of the total. Canada's fossil fuel extraction industry has increased its greenhouse gas emissions by 21.6% since 1990.

Canada is committed to reducing its greenhouse gas (GHG) emissions by 30% below 2005 levels by 2030 under the Paris Agreement. In July 2021, Canada enhanced the Paris Agreement plans with a new goal of reducing emissions by 40–45% below 2005 levels by 2030. Several climate change mitigation policies have been implemented in the country, such as carbon pricing, emissions trading and climate change funding programs. In 2019, the House of Commons voted to declare a national climate emergency in Canada.
