The United States and Japan have both reported that their greenhouse gas (GHG) emissions rose in 2010, reversing the declining trend of the previous years.
In its annual submission to the UN climate organization, the US said that its GHG emissions were up 3.2 percent in 2010 compared with the previous year after two consecutive year-on-year falls. Emissions hit 6.82 billion metric tonnes in 2010, up from 6.61 billion in 2009 but still below the 7.25 billion recorded in 2007 before the onset of the global recession.
