Global emissions of carbon dioxide from energy use rose 1.4 percent to 31.6 gigatons in 2012, setting a record and putting the planet on course for temperature increases well above international climate goals, the International Energy Agency said in a report scheduled to be issued Monday. The agency said continuing that pace could mean a temperature increase over pre-industrial times of as much as 5.3 degrees Celsius (9 degrees Fahrenheit), which would be a disaster for all countries.
The energy sector accounts for more than two-thirds of greenhouse gas emissions, so energy has a crucial role to play in tackling climate change.
The United States was one of the few relatively bright spots in the report. Switches from coal to shale gas accounted for about half the nation’s 3.8 percent drop in energy-related emissions, which fell for the fourth time in the past five years, dipping to a level last seen in the 1990s. The other factors were a mild winter, declining demand for gasoline and diesel, and the increasing use of renewable energy.
Emissions also fell in Europe.
But they rose 3.8 percent in China. That was one of the slowest increases in the past decade, and half of 2011’s rate of increase. The level of carbon dioxide emissions per unit of electricity generation has fallen about 17 percent. But China remains the largest contributor of carbon dioxide into the atmosphere, with about a quarter of global emissions.
Japan’s emissions jumped 5.8 percent as the country imported and burned large amounts of liquefied natural gas and coal to compensate for the loss of electricity production from nuclear plants that have been idle since a tsunami damaged the Fukushima Daiichi nuclear complex. (Wash Post, 6/10/2013)
