Majority of CO2 emissions linked to 57 producers and countries, report says

The vast majority of planet-warming carbon dioxide emissions since 2016 can be traced to a group of 57 fossil fuel and cement producers, researchers said on Thursday.

From 2016 to 2022, the 57 entities including nation-states, state-owned firms and investor-owned companies produced 80% of the world's CO2 emissions from fossil fuels and cement production, said the Carbon Majors report by non-profit think tank InfluenceMap.

The report found most companies had expanded their fossil fuel production since 2015, the year when nearly all countries signed the U.N. Paris Agreement, committing to take action to curb climate change.
