Terming bolder climate action as “self-preservation for every G20 economy”, UN climate chief Simon Stiell on Saturday urged the grouping’s leaders headed to Rio de Janeiro to carry out rapid cuts in emissions to prevent climate-driven economic carnage.

In an address at the COP29 here in Azerbaijan’s capital, Stiell, the Executive Secretary, United Nations Framework Convention on Climate Change (UNFCCC), said that G20 was created to tackle problems that no one country, or group of countries, can tackle alone.
