Sultan Al Jaber, the oil executive who is leading the COP28 climate summit in Dubai, sent shockwaves through the gathering by claiming in the days before the UN-backed talks that there is “no science” that says phasing out fossil fuels is necessary to keep global warming under a critical threshold — comments Al Jaber said were misinterpreted.

Al Jaber held a surprise news conference Monday where he fiercely defended his commitment to climate science, after an increasing number of scientists and advocates expressed alarm at the comments and concern for the direction of the talks.

The future role of fossil fuels is one of the most controversial issues countries are grappling with at the COP28 climate summit. While some are pushing for a “phase-out,” others are calling for the weaker language of a “phase-down.” Scientific reports have shown that fossil fuels must be rapidly slashed to keep global warming below 1.5 degrees Celsius — the goal of the Paris climate agreement, and a threshold above which scientists warn it will be more difficult for humans and ecosystems to adapt.

Al Jaber made the remarks during the She Changes Climate panel event on November 21, which came to light on Sunday in a story published by the Guardian, and in video that CNN has reviewed. Al Jaber was asked by Mary Robinson, former president of Ireland and current chair of the Elders Group, an independent group of global leaders, if he would lead on phasing out fossil fuels.

In his response, Al Jaber told Robinson, “there is no science out there, or no scenario out there, that says the phase-out of fossil fuel is what’s going to achieve 1.5.” He said he had expected to come to the She Changes Climate meeting to have a “sober and mature conversation” and was not “signing up to any discussion that is alarmist.”
