Delegates from almost 200 countries are meeting in Marrakech next week to consider the way ahead beyond Paris. The deal agreed in the French capital less than a year ago commits governments to moving their economies away from fossil fuels.

The report found pledges from governments that have ratified the accord would see the world on track for a rise in temperatures by the end of this century of between 2.9 and 3.4 degrees C.

The Paris climate pact comes into force less than a year since it was agreed. The last major climate deal – the Kyoto Protocol – took eight years to come into force. Paris is the first agreement tying rich and poor nations in a common endeavour to protect the climate. However, the national targets for cutting carbon emissions are voluntary. The UN tried a mandatory approach but countries that were failing to meet their targets simply quit.

The process of the Paris deal is binding, including a commitment for governments to keep returning to the issue to ratchet up the clean energy targets that they all agree are inadequate. Governments that rushed to enshrine Paris in law have had one eye on the US elections. Hilary Clinton has pledged to take President Obama’s emissions cuts further. Donald Trump wants to tear up the agreement.

What was agreed in Paris?

• To peak greenhouse gas emissions as soon as possible and achieve a balance between sources and sinks of greenhouse gases in the second half of this century

• To keep global temperature increase “well below” 2C (3.6F) and to pursue efforts to limit it to 1.5C

• To review progress every five years

• $100 billion a year in climate finance for developing countries by 2020, with a commitment to further finance in the future.
