US greenhouse gas emissions fell in 2015
After two years of increases, greenhouse gas emissions fell in 2015, reducing America’s overall climate pollution to below 1994 levels, according to the Environmental Protection Agency. The decline in 2015 was mainly because that year’s mild winter reduced demand for heat across the country, and electric power companies were using less coal and more natural gas to generate electricity than in previous years, the report says. Emissions fell 2.2 percent overall. The draft report is required to be produced annually under an agreement with the United Nations. It is open for public comment and scheduled to be finalised in April, according to an EPA statement.
