The article reports on the United States' climate-change policies. According to the article, about 13 bills have been introduced in the U.S. Congress that take varied approaches to reducing greenhouse gas emissions such as tax on fossil fuels and a mandatory system in which carbon dioxide emissions are capped. A group of senators has introduced the America's Climate Security Act that combines elements of 12 previous climate-change proposals.

The article discusses the issues that could hinder the formation of a climate-change treaty at the meeting in Copenhagen, Denmark on December 7-8, 2009. Eileen Clausen, president of the Pew Center on Global Climate Change, says that U.S President Barack Obama's negotiators would not carry on the treaty until the U.S. has decided on the greenhouse gases emissions cuts. It adds that the lack of money and forging of political agreements also slows the progress.
