The commitment that Canada made in the Paris accord is to reduce our emissions from 2005 levels by 30%.
The calculation of emissions changes slightly from year to year, based on the application of internationally accepted and continually evolving modelling methodologies. The most recent report that we submitted to the United Nations Framework Convention on Climate Change indicated that our 2005 emissions were 738 megatonnes, so 30% of that equals 517, necessitating a reduction of 221 megatonnes.
The other number we reported in our most recent report to the United Nations framework convention is that to achieve that target of 517 megatonnes in 2030, relative to what we projected emissions to be in late 2015—which we reported in early 2016 in Canada's second biennial report on climate change to the United Nations framework convention—would have required a reduction of 298 megatonnes. That's because emissions had grown since 2005, so we're trying to bend the curve that was actually going up for a while, since 2005.
