The European Union has established carbon limits for the second phase of the carbon trading scheme, a key step in cutting greenhouse gas emissions. The European Trading Scheme (ETS) aims to cut emissions by 8% of 1990 levels. Critics say that nations involved in the scheme had set their carbon allowance levels too high, and have not been aggressive enough in cuts. The EU set allowances for the 2008-2012 period to an average of 7% below the levels proposed by member states.

Electricity prices could double in Europe if power firms are to meet emissions reduction targets under the Kyoto protocol, says a report. Carbon prices are set to surge, and firms might pass this rise on to the wholesale market, says a report by consultancy Global Energy Decision.
