German utilities RWE and E.ON and Sweden’s state-owned Vattenfall were the top greenhouse gas emitters in Europe last year, a report by analysts Carbon Market Data said Thursday.

Last year RWE and E.ON together pumped out more carbon dioxide than Scandinavia's total carbon emissions. Norway, Denmark, Sweden and Finland's collective emissions in 2009 were around 234 million tonnes, according to Reuters estimates.

Vattenfall, Europe's fifth-largest electricity producer, emitted 91 million tonnes of carbon dioxide, 6 million tones more than during 2008.

Slightly more than half of Vattenfall’s electricity generated came from fossil-fuels, one fourth from nuclear power, 21 percent from hydro power and only 2 percent from other sources, such as wind, biomass or waste power.

Last year, Vattenfall completed the first step of its take-over on Nuon, by acquiring 49 percent of the shares of the Dutch power producer. Vattenfall will take full control of the company by 2015. 

The three companies, regulated under the European Union's Emissions Trading Scheme, also had the largest credit shortages last year.
