Between 1980 and 2000, roughly 58 territories decreased their annual carbon dioxide emissions. Together these territories reduced annual emissions by 1.9 billion tonnes; carbon emission increases from other territories were 3.5 times greater than this decrease.
Almost half of the decrease was in territories formerly in the Union of Soviet Socialist Republics, followed by Germany at 15%, Poland at 8%, and France at 6%. Decline in industrial production and factory closure contributed to some decreases. Nevertheless, the Russian Federation emitted the third largest quantity of carbon dioxide in 2000.
