Canada and the Kyoto Protocol

Ratification and Initial Commitments

Canada played a significant role in the negotiations leading to the Kyoto Protocol's adoption in Kyoto, Japan, in 1997. The Liberal government of Prime Minister Jean Chrétien signed the accord that year and, after a period of domestic debate and planning, formally ratified it in Parliament on December 17, 2002. Canada's commitment under the protocol was a legally binding target to reduce its greenhouse gas emissions to 6% below 1990 levels by the 2008 to 2012 compliance period. The 1990 baseline was established at 461 megatonnes of carbon dioxide equivalent, a figure from the Government of Canada's 1994 inventory. This ratification made Canada the only nation in the Americas with a binding emissions reduction obligation after the United States declined to ratify the treaty in 2001. The federal government introduced several plans in the early 2000s, such as Action Plan 2000 on Climate Change and the One Tonne Challenge in 2004, aimed at engaging the public and beginning the work toward the Kyoto target. The governance mechanisms for climate change during this period were later assessed as inadequate, with reporting also found to be insufficient to track progress against the ambitious international goal.

Rising Emissions and Domestic Challenges

Despite the ratification, Canada's emissions trajectory moved sharply in the opposite direction from its Kyoto target. Between 1990 and 2008, the nation's total greenhouse gas emissions increased by approximately 24.1%. Emissions climbed from 461 Mt in 1990 to a peak of 748 Mt in 2007, which was 33% higher than the level required to meet the Kyoto target. This increase was driven by multiple factors intrinsic to Canada's economy and geography. The energy sector, encompassing power generation, transportation, and fugitive emissions from fuel production, was the largest contributor, responsible for over 81.3% of total emissions by economic sector. Canada's status as the world's fifth-largest energy producer and a major exporter created economic challenges in meeting emissions standards, with the industry generating about a quarter of export revenues and employing some 650,000 people. The nation's vast distances requiring significant transportation and its cold climate, where fuel efficiency drops as temperatures fall, contributed to the highest per capita hydrocarbon consumption in the world at 8,300 kilograms of crude oil equivalent per person annually. The constitutional division of powers presented a persistent governance challenge, as provinces hold primary jurisdiction over natural resources and energy policy, making cohesive national action difficult. This tension had historical precedent, as the controversial National Energy Program introduced in 1980 had deeply divided the provinces, and since then no federal government had implemented a long-term, intergovernmental energy plan.

The Harper Government and Policy Shift

The election of a Conservative government under Prime Minister Stephen Harper in January 2006 marked a decisive turn in Canada's approach to Kyoto. Harper had previously denounced the protocol in a 2002 fundraising letter as a socialist scheme to suck money out of wealth-producing nations and advocated for a Made in Canada plan. His government abandoned the Kyoto targets, arguing they were unattainable and economically damaging. At the 2007 United Nations Climate Change Conference in Bali, Environment Minister John Baird stated Canada would not attempt to meet its Kyoto commitments, a position that drew international criticism for impeding progress on the Bali Action Plan. Harper opposed binding targets unless they were also imposed on major emerging economies like China and India, which were exempt from reduction requirements under Kyoto's first commitment period. The government introduced its own regulatory framework, the Clean Air Act in 2007, and in 2009 signed the non-binding Copenhagen Accord, committing to a new target of reducing emissions 17% from 2005 levels by 2020, a reduction of 124 megatonnes. This shift was aligned with a market-centred policy philosophy and a deliberate indifference to the Kyoto framework according to some analysts.

Canada was active in the negotiations that led to the Kyoto Protocol in 1997. The Liberal government signed the accord in 1997 and officially ratified it in parliament in December 2002. Canada's Kyoto target was a 6% total reduction in greenhouse gas emissions by 2012, compared to 1990 levels of 461 megatonnes. In 2011, Conservative Prime Minister Stephen Harper withdrew Canada from the Kyoto Protocol, making it the only country to repudiate the accord.

• January 2006: Harper government takes power and abandons Kyoto obligations. GHG emissions rose to 748 Mt that year.
• December 3-15, 2007: At the Bali conference, Canada argues it will not meet Kyoto targets.
• February 2009: Establishes the Clean Energy Dialogue with the United States for collaboration on clean energy technologies.
• 2009: Canada signs the Copenhagen Accord with a new 2020 target of 607 Mt, a 17% cut from 2005.
• 2010: Canada, along with Japan and Russia, states it will not accept new Kyoto commitments.

Greenhouse gas emissions fell to 690 Mt in 2008 and 2009 due to the global recession. Canada's emissions were expected to increase again with the economic recovery, fueled largely by the expansion of the oil sands. The Canadian Council of Chief Executives argued that a further extension of Kyoto would not be effective, as many countries, not just Canada, were not on track to meet their 1997 Kyoto commitments to reduce emissions. In 2009, Canada signed the non-binding Copenhagen Accord, agreeing to reduce its GHG emissions by 17% from its 2005 levels by 2020.

Withdrawal from the Kyoto Protocol

On December 13, 2011, one day after the conclusion of UN climate talks in Durban, South Africa, Environment Minister Peter Kent announced Canada's formal withdrawal from the Kyoto Protocol. Kent cited the agreement's failure to cover the world's two largest emitters, the United States and China, as a primary reason, stating it therefore could not work and that these two nations were responsible for 41% of the emissions covered by the protocol. He also argued that avoiding potentially crippling financial penalties, estimated by the government at $14 billion for non-compliance, was necessary, though other analyses suggested the cost of compliance could have been 20 times lower. The decision made Canada the first and only signatory to repudiate the treaty, drawing a widespread international response. In June 2012, the federal government passed the Jobs, Growth and Long-term Prosperity Act (Bill C-38), an omnibus budget bill which included the repeal of the Kyoto Protocol Implementation Act, the Canadian law that had codified the country's commitment. This legislative action formally erased the Kyoto targets from Canadian law. The withdrawal was consistent with the government's position that a new binding treaty with targets for all countries, as discussed in Durban for 2020, was needed instead of the existing Kyoto framework.

Emission Profiles and Sectoral Analysis

An analysis of Canada's emissions from 1990 to 2009 reveals the scale of the challenge posed by the Kyoto target and the composition of its greenhouse gas output. The primary greenhouse gas was carbon dioxide, accounting for 78.1% of total emissions, followed by methane at 13.4%, nitrous oxide at 7.1%, and hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride combined at 1.4%. The energy sector dominated emissions, with its 81.3% share broken down into key subsectors including transportation, stationary combustion sources, and fugitive sources. Transportation was a major component, with passenger cars and light trucks alone responsible for about 12% of Canada's total national emissions in 2008, making up 55% of all transportation emissions that year. Fugitive emissions from fuels, such as leaks, venting and accidents from oil and gas operations, contributed 9% of energy sector emissions. The industrial processes sector accounted for 7.2% of emissions, agriculture for 8.5%, and waste for 2.9%. Forecasts from Canada's Energy Outlook at the time indicated emissions were expected to grow by 139 million tonnes between 2004 and 2020, with more than a third of that increase coming from petroleum production and refining.

Canada's total greenhouse gas emissions increased by 24.1% between 1990 and 2008. Emissions rose from 461 Mt in 1990 to 748 Mt in 2007, which was an all-time high. The 2007 level was 33% higher than Canada's Kyoto target. Emissions data shows a trend of increase through the mid-2000s, moving far away from the 6% reduction target.

Canada's per capita greenhouse gas emissions increased by 3.2 percent between 1990 and 2008. A July 2011 report entitled "Environment: GHG Emissions Per Capita" ranked Canada 15th out of 17 countries and gave it a 'D' grade. Canada is one of the highest per-capita emitters in the OECD. The largest contributor to Canada's GHG emissions is the energy sector, which includes power generation, transportation, and fugitive sources.

Factors Affecting Canada's Emissions Trajectory

Several structural and economic factors help explain why Canada's emissions rose despite its Kyoto commitment. The nation's resource-based economy is a major driver, with the energy industry not only producing for domestic consumption but also for export, creating emissions within Canada for products used abroad. Geographic considerations are significant, as the vast distances between communities and the length and coldness of Canadian winters directly increase hydrocarbon consumption for heating and transportation. The Kyoto Protocol's structure, which used 1990 as a benchmark, actually accounted for these factors by setting Canada's target against its already high 1990 emissions, which were inflated by the country's climate, distances, and even lifestyle choices like low-density suburban living. Specific transportation data from 2008 shows light trucks contributed 29.2% of transportation emissions, heavy-duty trucks 27%, cars 25.4%, domestic aviation 5.3%, rail 4.4%, and domestic marine 3.6%. Another 14 percent of national emissions came from non-energy sources like agriculture and industrial processes. The expansion of unconventional oil resources, particularly the oil sands, was identified as a key source of future emissions growth, with upstream emissions from gas fields expected to decline slightly but emissions from unconventional resources and refining projected to soar according to Natural Resources Canada projections.

Legacy and Contemporary Climate Context

Canada's experience with the Kyoto Protocol left a lasting legacy on its climate policy framework and international reputation. The episode highlighted the deep tensions between federal and provincial jurisdictions, the economic pressures of a resource-intensive economy, and the political difficulty of implementing long-term emissions reduction strategies. The governance mechanisms and reporting for climate change were found to be inadequate during this period, lessons that informed later policy development. The withdrawal did not lessen the physical reality of climate change impacts on Canada, which is warming at more than twice the global average rate, with northern regions warming about three times as quickly. By 2026, Environment and Climate Change Canada forecasts indicated the year would likely rank among the four hottest on record globally, comparable to 2023 and 2025. Canada experienced more frequent and intense extreme heat events made two to ten times more likely by climate change, such as the record-shattering heat across multiple provinces and territories in 2025 that fueled the country's second-worst wildfire season on record. These events demonstrate the ongoing and escalating costs of a warming climate, threatening safety, well-being, and prosperity even in historically moderate cities like Vancouver and Halifax. The policy shift from Kyoto to the Paris Agreement represents a continued evolution, but the challenges of meeting ambitious targets remain a central feature of Canadian environmental politics, compounded by the accelerating pace of observed climate impacts across the country. The Canadian Centre for Climate Modelling and Analysis forecasted a global mean surface temperature in 2026 of 1.44 ± 0.09 °C above pre-industrial levels, with a 12% chance of exceeding the 1.5 °C Paris Agreement target in that single year.

Questions about Canada and the Kyoto Protocol

What was Canada's target under the Kyoto Protocol?

Canada's legally binding target under the Kyoto Protocol was to reduce its greenhouse gas emissions to 6% below 1990 levels by the 2008 to 2012 commitment period. The 1990 baseline was set at 461 megatonnes of carbon dioxide equivalent, as reported in the Government of Canada's 1994 inventory. This target was established when Canada ratified the treaty on December 17, 2002. The nation did not come close to meeting this goal, with emissions in 2005 already at 747 Mt, which was 33% higher than the target level required for compliance.

Why did Canada withdraw from the Kyoto Protocol?

The Conservative government of Prime Minister Stephen Harper announced Canada's withdrawal in December 2011. Environment Minister Peter Kent cited two main reasons. First, he argued the protocol could not work because it did not set binding targets for the world's two largest emitters at the time, the United States and China, which together were responsible for 41% of covered emissions. Second, he stated that staying in the protocol would subject Canada to severe financial penalties, which the government estimated at $14 billion, for failing to meet its emissions target, though other estimates suggested compliance costs could have been much lower.

Which sector was the largest source of Canada's emissions?

The energy sector was by far the largest source of Canada's greenhouse gas emissions, responsible for 81.3% of the total according to sectoral breakdowns. This sector includes transportation, stationary combustion sources for heat and electricity, and fugitive emissions from fuels like oil and gas leaks. Within transportation, which itself accounted for over half of the 162 Mt from transportation sources in 2008, passenger cars and light trucks were major contributors, accounting for about 12% of Canada's total national emissions. The nation's high per capita hydrocarbon consumption, cold climate, and resource-based economy all drove emissions in this sector.

What is the connection between Kyoto and current climate extremes in Canada?

While Canada's withdrawal from Kyoto was a policy decision, the underlying issue of climate change has intensified, with Canada warming faster than the global average. The increase in extreme heat events is a direct consequence. A 2025 report noted Canada experienced 12 extreme heat events each made two to ten times more likely due to climate change. By 2026, forecasts indicated the year would likely be among the four hottest on record globally. Events like the widespread heat waves and severe wildfire seasons of 2025 are consistent with climate change projections, showing the environmental challenges the Kyoto Protocol sought to address have become more urgent and costly over time.

How did Canada's emissions change during the Kyoto period?

Canada's greenhouse gas emissions increased significantly during the Kyoto period rather than decreasing. The country's target was a 6% total reduction from 1990 levels of 461 megatonnes by 2012. Instead, total emissions grew by approximately 24.1% between 1990 and 2008, reaching 732 Mt. Emissions peaked at an all time high of 748 Mt in 2007, which was 33% higher than the Kyoto target. A temporary decrease to 690 Mt occurred in 2009 due to the global recession, but the overall trend was one of substantial growth, moving Canada farther from its commitment.

What replaced the Kyoto Protocol for Canada?

Canada replaced its Kyoto Protocol commitment with the Copenhagen Accord. In 2009, Canada signed this non binding agreement, which committed the country to reduce its greenhouse gas emissions by 17% from its 2005 levels by 2020. This target translated to a reduction of 124 megatonnes, aiming for 607 Mt. Domestically, the federal government repealed the Kyoto Protocol Implementation Act in June 2012 through the Jobs, Growth and Long term Prosperity Act, known as Bill C 38. Canada's withdrawal from Kyoto was formally announced in December 2011, making it the only country to repudiate the accord.
