You mean like the coal plants...

...Dalton McGuinty keeps promising to shut down?

• NATURE - Sunday, Feb. 19, 2012 • One of the world’s top climate scientists has calculated that emissions from Alberta’s oil sands are unlikely to make a big difference to global warming and that the real threat to the planet comes from burning coal.

“The conventional and unconventional oil is not the problem with global warming,” Dr. Weaver said. “The problem is coal and unconventional natural gas.” The paper concludes that burning all the globe’s vast coal deposits would create a 15-degree increase in temperature.

Burning all the oil in the world would only raise temperatures by less than one degree, the paper concludes.
