“We have to get the emissions numbers right early on,” says Shakeb Afsah, a former World Bank environmental economist who founded data-analysis company Performeks LLC. (The Carbon Numbers Game, Bloomberg Markets, January 2011)

"...analysts at CO2 Scorecard argue that the United States will likely need new policies — say, a price on carbon pollution or further support for clean energy sources—if it wants to keep driving emissions down." (The Washington Post, 14-Sep-2012)
