Environmental activists were quick to react, warning that the involvement of a major figure from the oil industry could slow progress in the fight against global warming.
The head of the United Arab Emirates' national oil company was named as president of this year's COP28 climate talks, prompting fierce criticism from environmental activists.
Sultan Ahmed al Jaber, who heads up the UAE's Abu Dhabi National Oil Company (ADNOC), will be the first CEO to take the role at the UN summit, said a statement carried by the official WAM news agency.
"We will bring a pragmatic, realistic and solutions-oriented approach that delivers transformative progress for climate and for low carbon economic growth," Jaber said in the statement.
"I sincerely believe that climate action today is an immense economic opportunity for investment in sustainable growth," he added.
Jaber's appointment "poses an outrageous conflict of interest," said Harjeet Singh, head of the global political strategy at Climate Action Network International.
"The ongoing menace of fossil fuel lobbyists at the UN climate talks has consistently weakened outcomes of the climate conference, but this takes it to another dangerous and unprecedented level."
COP27, held in Egypt in November, concluded with the adoption of a hotly contested text on aid to poor countries affected by climate change, but failed to set new ambitions for lowering greenhouse gas emissions.
The UAE's hosting of this year's edition in Dubai in November and December has provoked concern from activists urging a shift away from oil, which produces greenhouse gases.
Too hot for humans
The UAE, one of the world's biggest crude producers, argues that oil remains indispensable to the global economy and is pushing the merits of carbon capture, removing carbon dioxide, the main greenhouse gas, as fuel is burned or from the air.
"Limiting global warming to 1.5C will require significant reductions in emissions, a pragmatic, practical and realistic approach to the energy transition and more help for emerging economies," the UAE's statement said, referring to the goal set at previous COP summits.
"The UAE is committed to multilateral cooperation and an inclusive process that brings together emerging economies with developed nations, civil society, and business to achieve the solutions and the pace of change required."
The UAE is one of the countries at the sharp end of climate change as it lies in one of the world's hottest regions, with summer temperatures nudging 50 degrees Celsius (122 degrees Fahrenheit).
