Emissions connected to top oil and gas firms may cause millions of heat deaths by 2100, study finds

Global witness analysis suggests 11.5 million deaths could be caused by burning of fuel produced by 2050

The emissions from burning oil and gas produced by the world's leading fossil fuel companies could cause millions of excess heat deaths before the end of the century, according to a new analysis.

The study from Global Witness found that the combined emissions from fossil fuels produced by Shell, BP, TotalEnergies, ExxonMobil and Chevron up to 2050 could result in 11.5 million excess deaths from heat by 2100.
