The UNโ€™s climate chief, Simon Stiell, has urged countries at the COP28 meeting on Monday to lift โ€œunnecessary tactical blockadesโ€, 24 hours before the official end of talks in Dubai that are focused on a deal to phase out fossil fuels.

โ€œFirst, clear the unnecessary tactical blockades out of the way,โ€ said Stiell, citing the need to reduce greenhouse gas emissions and support the transition of less developed countries.

โ€œAny strategic landmines that blow it up for one, blow it up for all,โ€ he told reporters.

He urged countries to remain ambitious as they sought a way to preserve the goal of checking global warming at no more than 1.5 degrees Celsius above pre-industrial levels.

โ€œI urge negotiators to reject incrementalism. Each step back from the highest ambition will cost countless millions of lives.

โ€œThe reality is the highest-ambition outcomes are the only way for all governments to leave Dubai with a win under their belt.

โ€œOne thing is for certain: โ€˜I win, you loseโ€™ is a recipe for collective failure. Ultimately, it is 8 billion peopleโ€™s security that is at stake,โ€ Stiell said.

Talks have intensified over calls to phase out fossil fuels, the top culprit in the planetโ€™s worsening crisis, but oil producers led by Saudi Arabia have put up tough resistance.
