UN report urges bold climate action

With global temperatures soaring and greenhouse gas emissions (GHG) reaching unprecedented levels, dramatic 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 last week by the UN Environment Program  (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 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 said.

To get back on track for the 2°C temperature rise above pre-industrial levels, emissions must be cut by at least 28 percent compared to current scenarios. Bringing it to within the 1.5°C limit will require a 42 percent cut.

If nothing changes, in 2030, emissions will be 22 gigatons 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.

Andersen’s message from Africa received unequivocal support on the other side of the world, in New York, where Secretary-General António Guterres issued a powerful appeal to world leaders.

“The emissions gap is more like an emissions canyon―a  canyon littered with broken promises, broken lives and broken records,” he said, stressing that change must begin at the top. 

“All of this is a failure of leadership, a betrayal of the vulnerable, and a massive missed opportunity.”

Reiterating that renewables have never been cheaper or more accessible, he urged leaders “to  tear out the poisoned root of the climate crisis: fossil fuels.”

He called on countries to commit to phasing out fossil fuels with a clear time frame aligned to the 1.5°C limit, as well as for those that gave yet to do so, to announce their contributions to the Green Climate Fund and the new Loss and Damage fund to “get it off to a roaring start.”

The appeal comes with just 10 days to go before the COP28 climate change conference in Dubai gets underway, where the first  Global Stocktake  of the  Paris Agreement  implementation is to conclude and inform the next round of  National Determined Contributions  that countries should submit in 2025, with targets for 2035.

Global ambition in the next round of NDCs must bring greenhouse gas emissions in 2035 to levels consistent with 2°C and 1.5°C pathways.

In the most optimistic scenario, where all conditional NDCs and  net-zero pledges  are met, limiting temperature rise to 2.0°C could be achieved.

However, net-zero pledges are not currently considered credible: none of the G20 countries are reducing emissions at a pace consistent with their net-zero targets. Even in the most optimistic scenario, the likelihood of limiting warming to 1.5°C is only 14 percent.  UN News
