International promises on greenhouse gas emissions

The Guardian, Thursday 25 June 2009

Scientists, via the UN's Intergovernmental Panel on Climate Change, have said that by 2020 developed countries must make 25-40% cuts in greenhouse gas emissions compared with 1990 levels. This is to give a better than even chance of limiting the ultimate rise in global temperature to under 2C, a level seen as representing dangerous climate change.
Here's what the main players have pledged so far by 2020, compared with 1990 levels:
EU ▼ 20-30%
US ◀ ▶0%
Japan ▼ 8%
Russia ▼ 10-15%
Australia ▼ 3-24%
Canada ▼ 3%
China, India and other developing nations will be asked at the Copenhagen negotiations to commit to reducing their emissions compared with "business as usual", but none has yet made a specific pledge.
