'Cut the theatrics', UN official on deadlocked COP29

The UN's climate chief told countries at the deadlocked COP29 summit on Monday to "cut the theatrics" as pressure mounts on G20 leaders to deliver a breakthrough.

As the UN climate talks limp into a second week in Azerbaijan, the world is no closer to a finance deal for poorer countries that will determine the success or failure of COP29.

UN climate boss Simon Stiell said that "bluffing, brinkmanship and premeditated playbooks burn up precious time and run down the goodwill needed".

"Let's cut the theatrics and get down to business," he told delegates assembled in a cavernous football stadium in Baku.

Nations have until Friday to break the impasse over how to raise $1 trillion a year for developing countries to cope with global warming.

"A successful outcome at COP29 is still within reach, but it will require leadership and compromise, namely from the G20 countries," UN Secretary-General Antonio Guterres said Sunday in Rio de Janeiro.

A fight is also brewing at COP29 over whether countries should recommit to last year's landmark pledge to move the world away from fossil fuels.

Saudi Arabia has been accused of obstructing efforts to address this and other measures to reduce record-high emissions of planet-heating greenhouse gases.
