After extending the Cop26 climate negotiations an extra day, nearly 200 countries meeting in Glasgow, Scotland, adopted on Saturday an outcome document that, according to the UN secretary-general is “an important step, but not enough”.

In a video statement released at the close of the two-week meeting, António Guterres said the agreement, known as the Glasgow Climate Pact, “reflects the interests, the contradictions, and the state of political will in the world today”.

But he warned: “We must accelerate climate action to keep alive the goal of limiting global temperature rise to 1.5 degrees”.

Under the Paris agreement of 2015, countries were asked to make changes to keep global warming “well below” 2C – and to try to aim for 1.5C – in order to prevent a climate catastrophe.

The goal is to keep cutting emissions until they reach net zero in 2050.
