Some point to the Financial crisis of 2007–2008 and the Province of Ontario closing its coal power plants as the reason for the reduction of greenhouse gas emissions during the premiership of Stephen Harper, factors that were outside his control.
[8] In 2012, the Conservative government revised the Canadian Environmental Assessment Act, reducing its scope to facilitate the approval of projects that would contribute to economic growth.
Foreign Affairs Minister John Baird explained the government's position: "Why should taxpayers have to pay for more than 10 reports promoting a carbon tax, something that the people of Canada have repeatedly rejected?
Quebec's Environment Minister Claude Béchard vowed to encourage the Tory government to continue with the $328 million funding previously committed for the province.
[14] According to an Environment Canada document, reported by the Montreal Gazette, "Media coverage of climate change science, our most high-profile issue, has been reduced by over 80 per cent" from 2007 to 2010.
In 2002, Harper wrote a letter to members of the former Canadian Alliance party, mentioning that the Accord is a "socialist conspiracy" and questioning climate science, and in a meeting with other Commonwealth countries in Uganda commented that Kyoto was a mistake that should not be repeated.
"[22] Harper considered the objectives implemented by Canada to meet its goals were not realistic and later criticized further the accord which did not set any targets for the world's biggest polluters.
Drummond, who has been consulted by political parties of all stripes, said that the "economic cost [of implementing Kyoto] would be at least as deep as the recession in the early 1980s", agreeing with the results of a study compiled by the environment department.
The Conservatives had appealed the Speaker of the House, Peter Milliken to make the bill invalid citing it was forcing them to spend money against its will, which was denied.
[33] In the 2007 Throne speech, the government officially abandoned the Kyoto objectives in favour of their policies and accords with Asian and Pacific countries in which Harper joined the US-led the Asia-Pacific Partnership on Clean Development and Climate on September 24, 2007, the United States, China, Japan, India, South Korea and Australia, several among them being among the biggest polluters.
The APP's plans goals are lower than the Kyoto Protocol and consists on the introduction of newer and cleaner technology including solar, coal and nuclear power.
Harper mentioned that these measures would "move industry from voluntary compliance to strict enforcement; replace the current ad hoc, patchwork system with clear, consistent, and comprehensive national standards, and institute a holistic approach that doesn't treat the related issues of pollutants and greenhouse gas emissions in isolation."
[40] However, critics including the World Wildlife Fund said that the greenhouse emissions in 2020 would still be higher than the 1990 levels, and Canada would not meet Kyoto targets before 2025, 13 years after its objectives.
[43] On December 20, 2006, Ambrose and Agriculture Minister Chuck Strahl announced $345 million of funding and other measures to promote the use of biodiesel and ethanol in policies related to the Clean Air Act.
[47] Harper later proposed a discussion with NDP leader Jack Layton in the light of growing concerns made by the United Kingdom government of Tony Blair as well as a report by Sir Nicholas Stern, a former chief economist World Bank who predicted a 20% drop of the global economy.
[55] John Baird who was also at the meeting mentioned that any agreements would have to include reduction targets in which the biggest polluters such as the United States, China and India must comply.
A last-ditch agreement, after difficult discussions, was made late in the Summit which consisted of a two-year plan which would lead to a new treaty replacing the Kyoto Protocol as well as additional negotiations until 2009 that would force countries to set basic parameters of greenhouse reduction goals.
[56][57] Climate changes was also a topic at the G8 meeting in Japan in July 2008 where the organization had agreed to fix an objective on reducing greenhouse emissions by 50 cent by 2050 although it was not clear whether the goal was based on either 1990 or current (2008) levels.
[61] However, on January 4, 2007, Ambrose was replaced by the President of the Treasury Board John Baird[62][63] In 2011, Canada's commissioner of the environment and sustainable development, Scott Vaughan, stated that the government was not only failing to meet Kyoto standards, but also those of other agreements it had signed.
