David Suzuki Foundation says Quebec, Ontario and B.C are "very good" regarding climate initiatives while Alberta and Saskatchewan rank as "worst".
On Wednesday the foundation released All Over the Map 2012: A Comparison of Provincial Climate Change Plans.
"In the absence of significant national policies to combat climate change, some provinces are stepping in with their own plans and policies. But those plans vary widely . . ." writes the report authors.
Since a previous study by the foundation, Ontario's rankings have risen due to clean energy initiatives and closing coal-fired power plants.
"Although B.C. still ranked among the top provinces, its rating went down, in part because of a failure to follow through on its ambitious climate change action plan and address emissions from oil and gas companies, including the proposed expansion and development of the shale gas industry."
Alberta and Saskatchewan were put at the bottom of the list due to reliance on oil and gas.
