The Alberta government acknowledges it likely missed its 2010 greenhouse gas emissions reduction goal and is now revamping the province’s overall climate-change strategy to meet future targets.

Alberta Environment said Tuesday the province didn’t meet its goal of reducing emissions by 20 megatonnes below business-as-usual projections in 2010, although final audited numbers have yet to come in.

The PC government has also been criticized for not being on track to meet its own target for 2020, which calls for a further emissions reduction. Alberta is supposed to start cutting absolute emissions that year, rather than just a reduction per unit of economic production.

With the province responsible for one-third of Canada’s growing greenhouse gas emissions, Environment Minister Diana McQueen said Thursday that Alberta is taking steps to ensure the next target in eight years time is met.
