EnvironmentBurning up: Four nations increase flaring to reverse global industry trendUS, Russia, Libya and Iran responsible for biggest increase in gas flaring during 2023An image from an optical gas imaging thermal camera shows a plume of heat from a flare burning off methane and other hydrocarbons next to an oil pumpjack in the US Permian basin in 2021. According to a satellite observation data-based study, increased flaring volumes in the US, Libya, Iran and Russia reversed the global oil and gas industry’s slow reduction in greenhouse gas emissions in 2023.Photo: AP/SCANPIXVladimir AfanasievEuropean Correspondent
