20/20 climate vision?

EU leaders at a Brussels summit have agreed a plan to cut emissions. This will involve the 27 EU countries cutting greenhouse gas emissions by 20% by 2020 compared with 1990 levels. The aim is also to try to raise renewable energy sources to 20% of total energy use. The package has become known as the 20/20/20 package, but scientists have already argued that these measures may not be sufficient to prevent serious climate change.
