Paris climate change deal: The key points you need to know

The world's first comprehensive climate agreement, with almost 200 countries taking action to tackle the problem, has been agreed.

Here are the key points:

  • Limit temperature rises to "well below" 2C above pre-industrial levels

This long-term goal aims to limit temperatures to a level beyond which the worst impacts of climate change are expected.

Additionally, nations would attempt to limit any increase to 1.5C, which the countries most at risk from the effects of climate change say is necessary to ensure their survival.

  • Five-yearly review of action plans

Under the draft agreement, countries would submit climate action plans for what they will do to curb global emissions.

These would then be reviewed and updated every five years based on growing levels of ambition.

Existing action plans up to 2030 are not enough to meet the 2C target, let alone 1.5C, and countries are being asked to update the contributions they have already made by 2020.

  • Finance for poorer countries

Poor countries will be financially supported so they are able to develop along a low carbon path and cope with the impacts of climate change.

Developed countries will contribute £100 billion (£66bn) a year until 2025, with cash flows scaled up after that.

  • Aim for greenhouse gases to peak and then be reduced

There are no specific figures for emissions cuts, but the goal is for greenhouse gases to peak as soon as possible, be rapidly reduced "in accordance with best available science" and then "achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century".

The latest report by the Intergovernmental Panel on Climate Change warned emissions would have to come down by between 40% to 70% for the 2C goal and 70% to 95% for the 1.5C goal by 2050.

It said that, ultimately, they would have to reach net zero to stabilise the climate.
