Union of Concerned Scientists

All told, they represent 56 percent of the US population, generate 62 percent of the country’s gross domestic product, and are responsible for 43 percent of the country’s annual carbon emissions. Just as important, cleaning up the power grid also lowers carbon dioxide emissions.

Four cheap solutions to climate change

Edouard Stenger

At a time where scientists are trying to figure out how to suck the excess carbon out of our atmosphere, Mother Nature has known how to do it for millions of years. Trees are very efficient at absorbing carbon dioxide. It is estimated that one acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen.

New Sabin Center Report Finds NYISO Could Price Carbon in Wholesale Electricity Markets

Law Columbia

Here in New York, for example, we already have three forms of more or less direct carbon pricing. The most direct of these is imposed on certain fossil fuel power plants by requiring them to purchase carbon dioxide emissions allowances as part of the Regional Greenhouse Gas Initiative.
