Countries responsible for at least two-thirds of greenhouse gas emissions have voluntarily set targets under the Copenhagen Accord.
China pledged to cut “carbon intensity” by 40-45% from 2005 levels by 2020, while the USA said it would aim to cut emissions by about 17% from 2005 levels in the same period.
India will reduce carbon intensity by 20-25% from 2005 by 2020, and the EU reconfirmed its target of a 20% cut in emissions by 2020 from 1990 levels, and 30% if other nations further improve their targets.
Brazil will aim to cut emissions to 36-39% below projected levels by 2020, and Japan’s emissions will be 25% below 1990 levels by 2020.
In an open letter published on Monday, Prime Minister Gordon Brown said: “They could lead to emissions peaking by around 2020 or before, representing the crucial first step towards the level of reductions required to hold global temperature increases to under 2°C.”
“We will still have to do more − and we must review this in 2015 as the Accord states.”
