OSLO (Reuters) - Citizens of the tiny Mediterranean principality of Monaco can apparently feel less worried that their speedboats, helicopters and cars are stoking global warming.

From being worst in the class -- except Spain -- among about 40 industrial states based on surging greenhouse gas emissions, Monaco has leapt to the ranks of the best after revisions filed to the U.N. Climate Secretariat in Bonn.

Monaco, with 32,000 inhabitants and an area of just 2 sq km (1 sq mile), said that it had previously sharply over-estimated the use of fossil fuels, blamed for stoking global warming.

"Emissions of greenhouse gases for 2004 are 3.1 percent below 1990," Monaco said in its annual submission to the Secretariat, estimating that total emissions of carbon dioxide fell to 104,200 tonnes in 2004 from 107,540 in 1990.
