But that calculation rested on an assumption that the world would reduce emissions by about 7% a year during the 2020s.Īs emissions have continued to rise, the annual rate of decline for emissions will now have to be much steeper to stay within the 1.5C limit. The Intergovernmental Panel on Climate Change calculated in 2018 that the world must nearly halve greenhouse gas emissions by 2030, compared with 2010 levels, in order to stay within the 1.5C threshold, and reach net zero emissions by 2050. Greenhouse gas emissions have continued to rise, despite a sharp fall in 2020 when Covid lockdowns were in place in many countries. That stocktake is likely to show the world is far off track, as the paper published on Thursday also shows. Campaigners remain unconvinced, however, and are planning a protest in Bonn on Thursday against the perceived conflict of interest in Al Jaber’s role.Īt Cop28, nations will undertake a “global stocktake” for the first time since the Paris agreement was signed in 2015, to assess whether they are on track to meet their commitments to cut emissions. Major figures in the talks, including John Kerry of the US and Frans Timmermans of the EU, have praised him. While heading the talks, Al Jaber has retained his role as head of UAE’s national oil company, Adnoc, which is planning to increase its oil and gas production capacity.Īl Jaber has previously told the Guardian that his dual role is a benefit to the talks, as he will bring a “business mindset” and galvanise the private sector. Sultan Al Jaber, the president-designate of Cop28, will arrive at Bonn on Thursday, under pressure to produce a plan for the talks that will achieve the “course correction” he has called for. Cop28 is seen as one of the last opportunities for the world to get on track to meet the goals of the 2015 Paris climate agreement, and stay within 1.5C. Governments are meeting in Bonn to prepare for a major UN summit on the climate, Cop28, this November in the United Arab Emirates. “We need to change policy and approaches in light of the latest evidence about the state of the climate system. He said the rate of annual increase in emissions had slowed down, but far stronger action was needed. Decisions made now will have an impact on how much temperatures will rise and the degree and severity of impacts we will see as a result.” Prof Piers Forster, the director of the Priestley Centre for Climate Futures at the University of Leeds, and lead author of the paper, said: “This is the critical decade for climate change.
That is down from 500bn tonnes just a few years ago, and at current annual rates of greenhouse gas emissions, of about 54bn tonnes a year over the past decade, it would run out well before the end of this decade. Only about 250bn tonnes of carbon dioxide can now be emitted, to avoid the accumulation of CO2 in the atmosphere that would raise temperatures by 1.5C.
