Carbon emissions down 11% since 2007 in the U.S.

Carbon dioxide emissions from burning fossil fuels in the United States are declining, according to a report published on the Earth Policy Institute website.
According to the agency, emissions peaked at more than 1.6 billion tonnes of carbon in 2007 but have been falling steadily, dropping to about 1.4 billion tonnes this year.
The recent recession played a role in the decline, combined with new pollution legislation and shifting consumer habits.
Oil, which is largely used for transportation, is the largest source of carbon emissions in the United States, the report states, but "average fuel efficiency, which had been deteriorating for years in the United States, started to increase in 2005 and keeps getting better. Americans are traveling farther on each gallon of gas than ever before," the Earth Policy Institute says.
On top of that, Americans appear to be driving less.
"For many years Americans as a group drove billions more miles each year than the previous one. But in 2007 this changed. Now more cars stay parked because more people live in urban areas, opt for public transit, work remotely, or retire and thus no longer commute to work," EPI writes.
