Since 1990, GHG emissions from these sectors had similar overall changes than what is observed since 2005, except for the transport sector that showed an increase (+32%) for the period from 1990 to 2020.From 2019 to 2020, GHG emissions from all individual sectors decreased by 4% to 14%, except for the agriculture sector where emissions grew by 3%.In 2020, the oil and gas sector and transport sector were the largest GHG emitters in Canada, accounting for 27% and 24% of total emissions, respectively.Indicators focusing specifically on the oil and gas, transport, agriculture and electricity sectors follow. This indicator shows GHG emissions reported by economic sector in which they are generated. the energy-based emissions from around 16 150 000 homes for 1 yearĮconomic sectors Greenhouse gas emissions by economic sector.removing over 21 000 000 gas-powered passenger vehicles from the roads for 1 year, or.These impacts contributed to the GHG emission decrease, especially in the transport sector where a 14% decrease was observed between 20.Īccording to the greenhouse gas equivalencies calculator developed by Natural Resources Canada, the 69 Mt CO 2 eq emission reduction for the period from 2005 to 2020 is equivalent to: The confinement measures introduced in 2020 due to the pandemic created an industrial slowdown and important reductions in trade and travel by air and land. The 9.3% decrease in GHG emissions between 20 was mainly a result of emission reductions from the electricity and heavy industry sectors. While the overall trend between 19 was an increase in GHG emissions there were certain sectors that saw a growth in GHG emissions over the time period whereas others saw a decrease.Ĭanada's overall emissions growth over the 1990 to 2020 period was driven primarily by increased emissions from oil and gas extraction as well as transport.

Emissions and removals from the land use, land use change and forestry sector (LULUCF) are excluded from national totals to allow for a focus on greenhouse gas released from human activity only. Emission levels for some years have been revised in light of improvements to estimation methods and availability of new data. The national indicator tracks 7 greenhouse gases released by human activity: carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, perfluorocarbons, hydrofluorocarbons and nitrogen trifluoride. Note: Data are presented as rounded figures. Note: Data are presented as rounded figures. The long-term trends presented must be interpreted with caution as the economic slowdown influenced results from 2019 to 2020. The latest year reported (2020) coincides with the 1st year of the COVID-19 pandemic which strongly affected a wide range of economic sectors, including the energy and transport sectors. Historically, following the Canada's ratification of the Kyoto Protocol, the base year was 1990. In 2021, Canada committed to reduce its GHG emissions by 40‑45 percent below 2005 levels by 2030. Since 2015 and the signing of the Paris Agreement, Canada adopted 2005 as the base year for its GHG emission reduction target. The indicators report estimates of Canada's emissions of GHGs over time. This changing climate has impacts on the environment, human health and the economy. These increases are primarily due to GHG emissions resulting from human activities such as the use of fossil fuels or agriculture. Climate change is caused by the increase in concentrations of greenhouse gases (GHGs) in the atmosphere. Climate change is one of the most important environmental issues of our time.
