Latvia has become the sixth EU member to take on the European Commission over CO2 emission quotas. The tiny Baltic state has joined Poland, Hungary, the Czech Republic, Slovakia and Estonia in saying the cap on emissions ordered by Brussels will damage its emerging economy. The Commission has told them to cut carbon emissions to just under 3-and-a-half million tonnes a year between 2008 and 2012. Latvia wants to be able to produce nearly double that amount, and will challenge the limit in the European Court of Justice, saying the way it was calculated was discriminatory. The Latvian prime minister, Aigars Kalvitis, says his country needs extra capacity for industry there to catch up with the rest of Europe.
