FACTBOX: Key issues at the EU summit on climate and energy

(Reuters) - European Union leaders meet in Brussels on Thursday and Friday to discuss a common EU energy policy and new goals to fight climate change.

Below is a summary of the key issues and proposals made by the European Commission on January 10 along with views from member states, environmentalists and industry.

CLIMATE CHANGE

The European Commission proposed the 27-nation bloc commit to cutting greenhouse gas emissions blamed for global warming by 20 percent compared to 1990 levels by 2020, boosting that goal to a 30 percent cut if other industrialized nations join in.

EU governments have supported the targets and urged emerging nations such as China and India to do their part as well.

Some environmentalists say the EU should make 30 percent a minimum target. Industry says 20 percent is tough but realistic.

Carbon dioxide is the main greenhouse gas, which scientists say heats the earth, raising sea levels and melting glaciers. Others include methane and nitrous oxide.

The EU currently produces about 14 percent of the world's greenhouse gas emissions. The United States produces 25 percent.

The 15 EU nations that were members before the bloc's 2004 enlargement pledged under the Kyoto Protocol to cut emissions by 8 percent by 2012. They are behind on that goal. In 2004 their emissions were down 0.9 percent compared to 1990 levels.
