Cleaning the Air

摘要

As the United Nations Climate Change Conference approached, the federal government prepared not only to debate the future of the Kyoto Protocol, but also to meet its existing obligations. So on November 21, 2005, Ottawa added the six greenhouse gases (GHGs) specified in the protocol — carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulphur hexafluoride — to the list of toxic substances specified in the Canadian Environmental Protection Act, 1999 (CEPA). Publishing this order was the government's first step in regulating GHGs under Part 5 of CEPA. It was also its first initiative in controlling the GHG emissions of large final emitters (LFEs).
