![]() In addition, Canada had the fastest population growth and its economy showed the second fastest growth among the G7 countries from 2005 to 2021.ĭespite these challenges, over the past 2 decades, Canada has seen a decoupling between growth of the economy and GHG emissions. While vast, Canada is also sparsely populated, which leads to longer travel times and higher demand for transportation than in smaller and/or more densely populated countries. This contributes to relatively higher energy use for space heating and cooling in buildings, compared with other industrialized countries. These include Canada's physical geography, demographic changes in its population and economic growth.Ĭanada has a highly variable climate. By doing so, it will help to limit global average temperature rise to well below 2 degrees Celsius.Ī wide variety of factors have an influence on the level of GHG emissions in Canada. In addition, Canada has committed to reaching net-zero emissions by 2050 and adopted the Canadian Net‑Zero Emissions Accountability Act in June 2021 to enshrine this commitment in federal legislation. In 2021, Canada enhanced its initial target and commited to reducing its GHG emissions by 40 to 45% below 2005 levels by 2030. To achieve this long-term goal, the Paris Agreement requires countries to increase their ambition every 5 years. In 2015, Canada and 194 other countries reached the Paris Agreement which aims to limit the global average temperature rise to well below 2 degrees Celsius and pursue efforts to limit the increase to 1.5 degrees Celsius. Therefore, immediate action to reduce these particular GHGs can have significant benefits for curbing near-term climate warming. As such, emission reductions of short-lived climate pollutants can reduce atmospheric levels of these GHGs at a much quicker pace than comparable reductions from longer-lived GHGs. Short-lived climate pollutants, such as methane (CH 4) and hydrofluorocarbons (HFCs), are GHGs known to be very potent with relatively short lifespans. In 2019, Canada’s GHG emissions per capita were 19.6 megatonnes of carbon dioxide equivalent (Mt CO 2 eq), Footnote 2 compared to 6.3 Mt CO 2 eq globally.ĭifferent GHGs have different global warming potential and lifespans in the atmosphere. During this period, Canada's share of total global GHG emissions remained at less than 2%, although it is one of the highest per capita emitters. Global GHG emissions grew by 23% between 20, Footnote 1 with the bulk of the growth occurring in developing countries. In 2021, about 28% of Canada's total GHG emissions came from the oil and gas sector, 22% from transport, 13% from buildings and 11% from the heavy industry sector. ![]() Specific activities include: driving vehicles, electricity production, heating and cooling of buildings, operation of appliances and equipment, production and transportation of goods, and provision of services and transportation for communities. ![]() Globally, almost 80% of GHG emissions from human sources come from the burning of fossil fuels and industrial processes. According to the Intergovernmental Panel on Climate Change, human-driven releases of GHG emissions disrupt the natural processes occurring in the atmosphere and are very likely to be the dominant cause of the observed warming that has occurred since the mid-20th century. Most greenhouse gases (GHGs) can be emitted by both natural processes and human activities. ![]()
