The report shows Manitoba's carbon equivalent (C02e) GHG emissions have hovered around 20 mega tonnes (mt) since 2000. Overall emissions have declined 2% from 20.7 C02e mt in 2000 to 20.3 C02e mt in 2010. Much of this decline is due to the global economic recession and several plant closures in Manitoba.

The Climate Change and Emissions Reduction Act had established an emissions reduction target of 6% below 1990 levels by 2012. But acting Conservation Minister Dave Chomiak admitted in December 2011 that Manitoba was unlikely to achieve this target. Manitoba's 2010 emissions are more than 12% above 1990 levels.

Although the act was first passed in June 2008, several important provisions of the Climate Change and Emission Reduction Act will not come into force until October 2012.

A December 2010 report by Manitoba's Auditor general heavily criticized the Manitoba government for failing to meet or accurately report on the status of its climate change initiatives, carbon inventory, or emissions reductions. The Auditor General specifically said that Manitoba's government needs to move to actual emissions data, and away from estimates and projections.
