By their estimations, coal - fired power plants coming online since the turn of the millennium will emit more CO2 than all other human coal burning has since the dawn of the industrial age: 660 billion metric tons over their 50 - year lifetime versus 524 billion metric tons between 1751 and 2000.

That sulfur dioxide market, run by the U.S. Environmental Protection Agency (EPA), has reduced sulfur dioxide levels by 40 percent since 1992 by allowing companies to buy and sell the right to emit the acid - rain forming pollution from coal - burning plants, which has increased the acidity of lake waters throughout the region.

I criticized this statement, noting that the actual emissions from U.S. coal - burning power plants declined only from 16.1 million tons to 12.4 million tons between 1980 and 1998 in the case of sulfur dioxide and from 6.1 million tons to 5.4 million tons between 1980 and 1998 in the case of nitrogen oxides (mostly emitted as NO, not NO2, but by convention measured as tons of NO2 - equivalent).

After all, coal burning is responsible for 40 percent of the 30 billion metric tons of CO2 emitted by human activity every year.

After conducting what he described as «more rigorous» calculations, Gervasi concluded «that the total release of CO2 from producing Natuna gas and burning of the LNG manufactured from the gas would be almost twice that emitted by burning an equivalent amount of coal.»

First, given the events of the past weeks in financial markets, I'm not sure how these groups intend to build confidence in a market trading a ton of carbon that is avoided by protecting a forest acre in, say, Borneo, for a ton emitted by a coal - burning power plant in Boston.

But this is silly, since the atmospheric lifetime of aerosols is just a matter of days, so once we stop burning coal, as we eventually must, the aerosols disappear quickly, unmasking the pent - up warming due to all the extra CO2 we emitted by not switching from coal to natural gas.

He has warned that if all the world's countries fail by 2030 to move away from burning coal for power (at least without capturing the emitted CO2), it will be impossible to avoid a long slide toward Earth becoming «a different planet» from the one human societies have experienced for thousands of years.

The researchers found that wood pellets burned in European and UK power plants, such as the Drax facility in North Yorkshire — which has transitioned some of its coal power generation capacity to wood pellets with the support of UK government subsidies — actually emit more CO2 per kilowatt hour than that generated by coal.

The rise of shale gas has had an environmental benefit as well — greatly reduced carbon dioxide emissions, because generating electricity by burning natural gas emits less than half as much carbon dioxide as burning coal.
