Coal, Gas and Ozone

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

SEPTEMBER 8, 2011

Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The situation is further complicated by uncertainty over the amount of methane that leaks from natural gas operations. Methane is an especially potent greenhouse gas. —Tom Wigley.

AUGUST 21, 2009

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
