Yes, we have a CO2-law, which is based on the aim to reduce the CO2 emissions by 10% from 1990 till 2010. This aim has not been reached. The CO2 emissions are same like in 1990, they didn't increased, what is kind of good, but they also didn't decreased, what is not really good. The CO2-law lasts till 2012. After 2012 there will be a revision of the law. This one will last till 2020 and the aim is to reduce the CO2 emission by 20%. This law affects just the CO2 emissions, because they make up 80% of the greenhouse gases.
