A new version of the “global stocktake” is expected today, said UN climate change executive secretary Simon Stiell, who added that “the areas where options need to be negotiated have narrowed significantly”. During a briefing, Stiell said two main areas of focus are the level of ambition parties would show on tackling mitigation, and whether there is a will to “back this transition with the proper means of support to deliver it”. He added: “Let me assure you — from our viewpoint at UN Climate Change — the highest levels of ambition are possible for both.”
