OPINION: At first glance the decision to put the chief executive of one of the world’s biggest oil companies in charge of the next United Nations climate summit looks like the very definition of a conflict of interests.

Abu Dhabi National Oil Company (Adnoc) plans to invest $150 billion by 2027, with the lion’s share geared towards increasing its oil and gas production capacity.

To their critics, Adnoc and its peers in Saudi Arabia and Qatar seem to be engaged in a lucrative grab for market share during an energy transition that will continue to require fossil fuels for decades to come.
