Canada's GHG emissions on steady upward trend, says report

Okay - I'm confused. The report says this:

The report, prepared by Environment Canada and submitted annually to the United Nations Framework Convention on Climate Change, shows 726 megatonnes of emissions in 2013, still three per cent below Canada’s output in 2005.

However, under the international Copenhagen Accord signed in 2009, Canada committed to reduce its emissions by 17 per cent below 2005 levels by 2020 _ and the trend is now firmly heading the wrong way.

But then goes on to say

All data in the report was also revised upwards following new reporting guidelines adopted by the UN in 2013, making year-to-year comparisons difficult in the absence of the complete revised data set.

So if the second quote is right, how far can we trust the first one?
