UN: World severely off track to limit planet-heating emissions 

PARIS, Nov 15 — The world is “failing to get a grip” on climate change, the UN warned Tuesday, as an assessment of climate pledges shows only minor progress on reducing emissions this decade.

In a report released just weeks before high-stakes negotiations on limiting global warming, the United Nations climate change organisation said the world was not acting with sufficient urgency to curb greenhouse gas emissions.

With temperatures soaring and 2023 expected to become the warmest year so far in human history, scientists say the pressure on world leaders to curb planet-heating greenhouse gas pollution has never been more urgent.

The UN found that combined climate plans from nearly 200 nations would put the world on a path for 2030 carbon emissions just 2 per cent below 2019 levels.

That is far short of the 43 per cent fall that the UN’s IPCC climate panel says is needed to limit warming to the Paris deal target of 1.5 degrees Celsius (2.7 degrees Fahrenheit) since the preindustrial era.

“Every fraction of a degree matters, but we are severely off track. COP28 is our time to change that,” said UN Climate Change chief Simon Stiell.

He called for climate talks in Dubai this month to mark a “clear turning point” for a world already wracked by increasing floods, heatwaves and storms.

Scientists have warned that humanity is dangerously close to blowing past the 1.5C global heating limit, risking intensifying impacts.

“The world is failing to get a grip on the climate crisis,” said UN Secretary-General Antonio Guterres, warning countries were not acting fast enough to avoid catastrophe.

“Inch by inch progress will not do. It is time for a climate ambition supernova in every country, city, and sector.”

President Joe Biden announced Tuesday billions more dollars in investment to try to make the United States more resilient to global warming, saying “anyone who wilfully denies the impact of climate change is condemning the American people to a very dangerous future.”

“The impacts we’re seeing are only going to get worse, more frequent, more ferocious and more costly,” he added.

Closing the gap

Under the 2015 Paris deal, countries are required to submit ever deeper emission cutting plans, known as Nationally Determined Contributions, or NDCs.

The latest annual UN assessment of these plans includes 20 updated NDCs submitted between September 2022 and September 2023, including from Mexico, Turkey, Norway and COP28 hosts the United Arab Emirates.

Last year’s report used a 2010 benchmark and found that if the world’s NDCs were fully implemented, emissions would be 10.6 per cent higher by 2030.

This time around there has been “only a fractional improvement”, Stiell said, with emissions projected to be 8.8 per cent higher in 2030 than in 2010.

In September, a global stocktake of the world’s progress on averting the worst impacts of climate change warned that the world was far off target.

Global greenhouse gas emissions must peak by 2025 and drop sharply thereafter to keep the 1.5C limit in view, it said, drawing from a major scientific assessment by the UN’s IPCC science advisory panel.

Achieving net zero carbon emissions by 2050 — another Paris goal — will also require phasing out the burning of all fossil fuels whose emissions cannot be captured or compensated.

‘The only chance’

A response to the stocktake will form the centrepiece of the November 30 to December 12 COP28, with crucial debates over the future of oil, gas and coal — the main drivers of planet-heating emissions.

But countries are still failing to match their actions to what scientists say is needed to avoid blasting past the world’s agreed global warming limits.

This month a United Nations Environment Programme report found that planned production increases in major petrostates would result in 460 per cent more coal, 82 per cent more gas and 29 per cent more oil than would be consistent with limiting warming to 1.5C.

And the room to manoeuvre might also be tighter than previously understood.

In October, new research found that the amount of CO2 the world can emit and still have a 50 per cent chance of limiting warming to 1.5C could be used up in six years.

“We are still miles off where we need to be for limiting global warming to 1.5C,” said Tom Evans, policy advisor at the think tank E3G, adding that the response to the stocktake will be “critical”.

“It’s the only chance we have to make sure that the next set of climate targets — due by 2025 — will put us in a place to close this gap.” — AFP
