While major oil producers Saudi Arabia and the United Arab Emirates are touting carbon capture and storage as a cure for global warming, some experts warn that the emerging technology is unproven and expensive and should not replace efforts to phase out hydrocarbons. "Renewables are not and cannot be the only answer," argued Al Jaber, who is both the head of state oil giant ADNOC and the country's climate envoy. "If we are serious about limiting industrial emissions, we need to get serious about carbon capture technologies," he said at the United Arab Emirates' Climate Tech event in Abu Dhabi. “In any realistic scenario that gets us to net zero … carbon capture technology will play a role. Without it, mathematics simply does not work. "We need to phase out emissions," Al Jaber added, reiterating his position that oil remains irreplaceable for the global economy and key to energy financing. (Kareem Sahib)
