With global temperatures soaring and greenhouse gas emissions (GHG) reaching unprecedented levels, dramatic climate action is needed to steer the world away from runaway climate change and align it to the objectives of the Paris Agreement, a major UN report has found.
The 2023 Emissions Gap Report, released on Monday by the UN Environment Programme (UNEP), carried a clear message – unless countries step up climate action and deliver more than promised in their 2030 pledges, the world is heading for a 2.5-2.9°C temperature rise above pre-industrial levels.
Presenting the report from Nairobi, UNEP Executive Director Inger Andersen said that no person or economy is being left untouched by climate change, underscoring the urgent need to “stop setting unwanted records on greenhouse gas emissions, global temperature highs and extreme weather.”
“We must instead lift the needle out of the same old groove of insufficient ambition and not enough action, and start setting other records: on cutting emissions, on green and just transitions and on climate finance,” she emphasized.
To get back on track for the 2°C temperature rise above pre-industrial levels, emissions must be cut by at least 28 per cent compared to current scenarios. Bringing it to within the 1.5°C limit will require a 42 per cent cut.
If nothing changes, in 2030, emissions will be 22 Gigatonnes higher than the 1.5°C limit will allow – approximately the total current annual emissions of the United States, China and the European Union (EU) combined.
