LONDON (Reuters) - European Union industrial carbon emissions rose by up to 4 percent last year, analysts estimate, still far below 2008 levels and leaving the bloc on course to beat its 2020 climate target.
The EU emissions trading scheme (ETS) caps the emissions of about 12,600 installations, including power plants, factories and oil refiners, and the European Commission publishes emissions data in April of each year.
Analysts already estimate, based on industrial output data, that emissions rose last year by 2-4 percent, compared with a drop of nearly 12 percent in 2009.
"It was a mixed year with some industrial output going up, others down, and not a huge improvement in power demand across the bloc as a whole," said Barclays Capital analyst Trevor Sikorski, who estimated carbon emissions were up 4 percent.
Carbon analyst Matteo Mazzoni at Italy's Nomisma Energia estimated the rise at 2.7 percent. IdeaCarbon analyst Alessandro Vitelli estimated a rise of 2-4 percent.
The scheme accounts for about 40 percent of total EU greenhouse gas emissions.
The European Commission, which oversees the scheme, is under pressure to trim a glut of emissions permits, and has already limited how far polluters can offset their emissions by buying carbon credits from outside the EU from 2013.
The EU as a whole is split on whether to adopt a tougher target to cut total greenhouse gas emissions by 2020. Some governments want a 30 percent cut, more than the present 20 percent goal, fearing the bloc is slipping behind in a global clean technology race.
Total EU greenhouse gas emissions were about 4.6 billion metric tons in 2009, says the European Environment Agency. If these rose in line with industry carbon last year, that would imply the bloc was about 300 million metric tons above its target of 4.5 billion metric tons of greenhouse gases in 2020.
The EU will undercut that target, say EU climate officials, if the bloc meets renewable energy and efficiency goals.
EU ETS emissions rose last year, as power demand and broad industrial output rose, meaning businesses burned more fossil fuels to generate electricity and heat, said Sikorski.
In addition, higher gas prices encouraged power plants to burn more coal, which emits more carbon dioxide, he added.
Within that big picture there were some falls: Cement production was down in the first 11 months of the year, and so was oil refining.
Outside the emissions trading scheme, a slowdown in oil refining suggested that carbon emissions from transport may have fell, while two successive cold winters would have led homeowners to burn more gas and other fuel.
Company results this week have supported the notion of stronger power demand last year, especially from coal.
Drax, operator of Britain's biggest coal plant and largest source of carbon emissions, said that its CO2 emissions rose 13 percent, and Europe's biggest emitter German utility RWE reported CO2 up 11 percent.
In 2009, EU ETS emissions were 1.873 billion metric tons of CO2, down 11.6 percent as a result of the financial crisis.
