The debate over the future of fossil fuels, the biggest cause of global warming, is the key battle at the Cop28 climate summit hosted by the oil-rich United Arab Emirates. As neighbouring Saudi Arabia – the world's biggest oil exporter – ruled out phasing down oil, gas and coal, and activists sounded the alarm over fossil fuel lobbying at the talks, the chances of agreeing an ambitious deal looked slim.
The latest version of a potential agreement includes two drastically different options: phasing out fossil fuels or not addressing the issue at all, negotiators said on Tuesday, as they headed back into tough talks due to end next week.
