A coalition of environmental groups and charities have set out what they want to see from a global climate deal.
The group, including Greenpeace, WWF, the RSPB and Christian Aid, said an international agreement should include ambitious plans by countries for taking action both before and after 2020.
It should also provide a clear legal framework for delivering and monitoring greenhouse gas emissions cuts.
An agreement, which backers want to see signed at the end of 2015, establish a framework with rolling commitments to reduce emissions and support efforts to adapt to a changing climate, they added.
