Overall, average annual temperatures are expected to increase.Examples include how people commute to work, where businesses decide to locate their manufacturing facilities and the decisions made to increase the efficiency of industrial processes or to manufacture more energy-efficient products. Other important factors influencing GHG emissions include the adoption of more efficient practices and equipment by consumers and industry as their knowledge about their choices and the impacts of those choices on the environment is improving. Over this period, technological improvements and regulations have been adopted and implemented in various economic sectors, particularly for electricity generation, to help reduce emissions. In addition, Canada had the fastest population growth and its economy showed the second fastest growth among the G7 countries from 2005 to 2019.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 tabled the Canadian Net‑Zero Emissions Accountability Act in November 2020 to establish a legally-binding process to achieve that goal. Canada is committed to implementing its strengthened climate plan, A Healthy Environment and a Healthy Economy, to ensure Canada not only meets, but also exceeds its 2030 emissions reduction goal. Therefore, immediate action to reduce these particular GHGs can have significant benefits for curbing near-term climate warming.Ĭanada aims to reduce its GHG emissions to 30% below its 2005 emission levels by 2030. 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. GHGs have different global warming potentials and different lifespans in the atmosphere. During this period, Canada's share of total global GHG emissions remained at less than 2%. Global GHG emissions grew by 23% between 20, Footnote 1 with the bulk of the growth occurring in developing countries. In 2019, about 26% of Canada's total GHG emissions came from the oil and gas sector, 25% from transportation, 12% 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.
