The UN climate change conference in Dubai, hosted by the United Arab Emirates, is on the verge of a significant breakthrough in addressing climate change. The UAE negotiating team expresses 'cautious optimism' that COP28 will commit to gradually reducing and possibly eliminating fossil fuels over the coming decades. This is a remarkable shift, as fossil fuels were rarely discussed at previous climate conferences until COP26 in Glasgow in 2021, where the focus was on phasing down coal. While the commitment in Dubai may not set a specific expiry date for fossil fuel use and will probably allow for ‘abated’ fossil fuels with carbon capture, it represents a historic acknowledgment of the need to address the primary source of climate change. Sultan al-Jaber, COP28 president and head of UAE state oil company Adnoc, has been advocating for a fossil fuel phase-out; this underscores the significance of addressing climate change even in such a major oil-producing country. Interestingly, the number of delegates representing fossil fuel interests has quadrupled compared to COP27: see
