“There will be coal burning.” Negotiators from around the world produced a four-page climate-change accord (pdf) after some sleep-deprived haggling over the weekend in Lima, Peru, but the agreement could be summed up in those five words.

On October 2, the Boundary Dam power plant in Saskatchewan became the first full-sized coal-fired boiler to capture the copious carbon dioxide that had previously billowed from its smokestack, preventing the greenhouse gas from entering the atmosphere. On the resulting invisible stream of hot smoke ride the hopes of combating climate change while still burning [...]

At the beginning of this year, the Golden State officially launched its long-discussed market-based system to reduce greenhouse gas (GHG) emissions.
