After a summer of climate-related flooding, droughts and heatwaves in parts of Europe, a new ranking by WWF reveals the continent's worst climate polluting power stations.
Dirty Thirty ranks the least efficient among the biggest carbon dioxide (CO2) emitters and finds that 27 of the 30 dirtiest power plants are coal-fired, with Agios Dimitrios in Greece, Frimmersdorf in Germany, and Abo?o in Spain heading the WWF table.
The global conservation organization looked at the absolute CO2 emissions of power stations (million tonnes of CO2 per year) in 25 EU countries and ranked the 30 biggest emitters according to their level of efficiency (grams CO2 per Kilowatt hour). Most of the Dirty Thirty are located in Germany (9 plants), followed by Poland (5 plants), Italy, Spain, and the UK (4 plants each). Greece has two lignite plants ranked in first and fourth place.
According to scientists, CO2 emissions are the main reason for global warming and devastating climate impacts on people and nature.
"The power sector is responsible for 37 per cent of all man-made CO2," said Imogen Zethoven, head of WWF's global PowerSwitch! campaign.
"Coal-fired power stations rank dirtiest, because they use the most CO2-intense fuel. To switch off global warming we have to replace them with cleaner alternatives, such as gas and renewables."
Germany comes off particularly badly in the survey. It is home to five of the ten dirtiest plants, with four of them are run by the German power giant RWE, the biggest CO2 emitter in the European power sector. Dirty Thirty shows that only half a dozen companies account for most of Europe's dirtiest power stations: 19 of the 30 plants analyzed are run by RWE (German), Vattenfall (Swedish), Enel (Italian), Endesa (Spanish), E.ON (German), and EDF (French).
Over the next 20 years many of Europe's worst polluting coal power plants will be decommissioned - a historic window of opportunity to cut CO2 pollution. The Dirty Thirty replacement scenarios show that a switch to highly efficient gas in the decommissioned plants would slash CO2 emissions by 47.8 per cent by 2030. Replacing them with new coal plants would result in a mere 13.5 per cent reduction of CO2, nowhere near the deep cuts required. Replacing the old plants with renewable energy sources would result in a massive 73.4 per cent cut in CO2 emissions.
"A crucial part of the solution to CO2 emissions from power production is the European Emission Trading Scheme," said Zethoven. "WWF is pushing for strong pollution limits and clear incentives to invest in wind, water and sun to be included in the second phase. Only tough limits on CO2 will force the utilities to replace dirty coal plants with cleaner gas or clean renewables."
European governments have a vital role to play by enforcing strict pollution limits under the European Emissions Trading Scheme (ETS). From January 2005, the ETS has placed CO2 limits on the chimney stacks of big companies. Companies that exceed their limits have to pay the penalty by being forced to buy unused pollution allowances from cleaner companies. Tough pollution limits combined with powerful financial incentives to invest in cleaner, more efficient technologies would transform the power sector and reduce its CO2 emissions. Unfortunately, EU governments agreed to weak limits and weak incentives. Now the ETS is being reviewed, opening up a big opportunity to get it right next time.
