Utilities can lower emissions and make money as well. According to Reuters:
U.S. utility Entergy Corp. on Wednesday said it made a new commitment to lower greenhouse gas emissions from its power plants.
The company said it plans to voluntarily cut emissions from its plants and stabilize them at a level 20 percent lower than in 2000 for the period of 2006 to 2010.
Entergy made its first plan to reduce its greenhouse gas emissions in 2001 in partnership with U.S. green group Environmental Defense.
Under that plan, which covered the period of 2000 through 2005, Entergy said it cut its greenhouse gas levels by 23 percent.
