Mr. Speaker, our government is committed to addressing the challenge of climate change and has followed through on that commitment with concrete action, both internationally and domestically.
Internationally, Canada continues to work with its global partners to address climate change. Canada is an active and constructive participant in the ongoing climate change discussions under the United Nations Framework Convention on Climate Change. At the same time, Canada is taking a leadership role on a number of international climate change initiatives outside the United Nations. For instance, our government is working with international partners through its chairmanship of the Arctic Council and the Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants, such as black carbon and methane. This work is especially important for Canada, as short-lived climate pollutants significantly impact our north.
Domestically, our government is implementing a sector-by-sector regulatory approach to reducing greenhouse gas emissions while maintaining economic competitiveness. It has started with the transportation and electricity sectors, two of the largest-emitting sectors of the Canadian economy.
In the transportation sector, the Government of Canada continues to collaborate with the United States to develop standards for regulating greenhouse gases produced by passenger automobiles and light trucks and heavy duty vehicles.
Recently, at the September climate summit, the Government of Canada announced the final regulations for 2017-2025 model year light duty vehicles as well as its intent to move forward with further regulations for heavy duty vehicles for the post-2018 model years. As a result of these actions, 2025 model year passenger vehicles and light trucks will emit about half as many greenhouse gas emissions as 2008 models. Greenhouse gas emissions from the 2018 model year heavy duty vehicles will be reduced by up to 23%.
In the electricity generation sector, Canada already has one of the cleanest systems in the world, with 77% of its electricity supplied emitting no greenhouse gases. In 2012 our government introduced a tough new regulatory performance standard for coal-fired electricity generation that makes Canada the first major coal user to ban construction of traditional coal-fired electricity generation units. These regulations will help contribute to reductions of 46% in this sector over 2005 levels by 2030.
At the climate summit in New York, Canada also announced its intent to regulate hydrofluorocarbons, or HFCs. These regulations will align with the regulations recently proposed by the U.S. and will apply to HFCs in bulk and to certain manufactured products containing HFCs.
Our approach is generating results. It is estimated that as a result of the combined actions of all levels of government, businesses, and consumers, Canada's greenhouse gas emissions in 2020 will be 734 megatonnes. This is 128 megatonnes lower than where our emissions would have been in 2020 if no action had been taken since 2005. As we know, no action was taken by the Liberals.
