Reuters: Russia’s greenhouse gas emissions rose by a tiny 0.3 percent in 2007 to the highest since the 1990s economic downturn caused by the break-up of the Soviet Union, according to data submitted to the United Nations. Emissions edged up to 2.192 billion tons of carbon dioxide equivalent in 2007 from 2.185 billion in 2006, according to official figures filed to the U.N. Climate Change Secretariat in Bonn. The level was the highest since 1994.
