UN climate talks end with limited progress on emissions targets

Partial agreement at COP25 that countries must be more ambitious to fulfil Paris goals

Climate talks in Madrid have ended with a partial agreement to ask countries to come up with more ambitious targets to cut greenhouse gas emissions in order to meet the terms of the 2015 Paris accord.

Few countries came to this year's talks with updated plans to reach the Paris goals, though the EU finally agreed its long-term target of reaching net zero emissions by 2050. Experts say more ambitious emissions cuts are needed globally if the Paris pledge to hold global heating to no more than 2C is to be met.
