Energy ministers, oil executives and green investors gathered this week to mark a half-century since the formation of the International Energy Agency and to assess its new role as the world's shepherd toward a green future from a fossil fuel past. Top OPEC+ oil producers, international oil company executives and some analysts have, however, questioned the IEA's recent policy recommendations and its interpretation of the oil market data it collects from its 31 member nations. That was triggered by a controversial 2021 IEA report in which the agency said there should be no investment in new oil, gas and coal projects if the world was serious about meeting climate targets.
