World leaders are being urged to set out “very clear ambition and targets” to cut emissions at a climate summit being co-hosted later this week by the UK.

The online summit on Saturday hosted by the United Nations, UK and France marks five years since countries agreed the world’s first comprehensive treaty on tackling climate change, the Paris Agreement.
