The country's first auction of emissions permits set the price of releasing carbon dioxide into the atmosphere at $3.07 per ton. The Regional Greenhouse Gas Initiative, a consortium of 10 states in the Northeast, held the first U.S. cap-and-trade auction last week and announced the results today, the Associated Press reports. Under the program, companies buy permits to emit a certain amount of greenhouse gases, and if they reduce their emissions they can sell the permits to other companies for a profit.

The City of Chicago wants to cut its emission of greenhouse gases to three-quarters of 1990 levels by 2020, and one-fifth of 1990 levels by 2050. The Associated Press reports that the plan includes updating the city's building code to improve insulation and heating and cooling systems in all buildings, increasing recycling and carpooling, and promoting alternative fuels. Chicago emits 34.6 metric tons of greenhouse gases each year.

Chemists at Brandeis University in Massachusetts have found a way to separate fluorine from carbon compounds, opening the door to eliminating one of the most potent types of greenhouse gas. Science News reports that, so far, the scientists only have a proof of their concept, but hope to develop it into a practical process for breaking up hydrofluorocarbons. The volume of HFCs is much lower in the atmosphere than carbon dioxide, but they trap more heat and do not break down easily.
