In 2024, just over thirty companies affected the global climate more than the entire population of many countries. According to an update of the Carbon Majors<\/a> database, exactly 32 companies are responsible for more than half of the carbon dioxide emissions<\/a><\/strong> from fossil fuel and cement production. That’s a number that’s down from 36 in 2023, but it’s not good news: it means that emissions are being concentrated on a shrinking pool of large producers, while overall production continues to increase. <\/p>\n\n

The report links 34.7 gigatonnes of greenhouse gases in 2024 to 166 of the largest oil, gas, coal and cement companies, a 0.8 percent increase over 2023. “Each year, global emissions become increasingly concentrated in a shrinking group of high-impact producers, while production continues to grow,” notes Emmett Connaire<\/strong>, senior analyst at InfluenceMap<\/a> <\/strong>and lead author of the study. It’s a picture that makes it clearer where to take action and, at the same time, more urgent to do so. <\/p>\n\n

The top ten emitters<\/strong><\/h3>\n\n

The composition of the largest emitters is striking: the top 10 emitters are all full or majority publicly controlled companies, and they alone generated 27.6 percent of global fossil fuel-related emissions<\/strong> in 2024. Widening the view, the 70 state-owned companies considered in the analysis produced 54.4 percent of fossil emissions, while 93 privately held companies stop at 23.7 percent. It is not just a matter of numbers, but of governance and national policies: five of the top 10 state-owned companies are Chinese<\/strong>, two are Russian<\/strong>, and the others belong to Saudi Arabia, India and Iran.<\/strong> <\/p>\n\n

Topping the list is Aramco<\/strong>, the Saudi national company, which alone contributed 4.3 percent of global CO2 emissions<\/strong> associated with fossil fuels and cement in 2024. In the transition between 2023 and 2024, the majority of state-owned companies increased their emissions: 38 up, 29 down. In contrast, among privately owned companies, reduction prevails: 54 have recorded a decrease, 39 an increase. Yet their weight remains significant, with names that need no introduction: ExxonMobil, Chevron, Shell, BP, and ConocoPhillips<\/strong> lead the pack. Rounding out the Top 10 are Coal India<\/strong> (3.9 percent of global emissions), CHN Energy<\/strong> (3.9), National Iranian Oil Company<\/strong> (3.1), Gazprom<\/strong> (2.7), Jinneng Group<\/strong> (2.6), China Cement (<\/strong>2.4), Rosneft <\/strong>(1.8), CNPC <\/strong>and Shandong Energy<\/strong> (1.7). The first Italian company is 38th: it is Eni<\/strong>, with 0.55 percent of world emissions. Small percentage, but a lot. <\/p>\n\n

New forms of accountability<\/strong><\/h3>\n\n

Historical tracking of corporate emissions is fueling new forms of accountability. In the United States, more than a dozen states have invoked these numbers to support proposals for“climate superfunds<\/strong>“: funds financed by large fossil fuel companies to protect communities from damage already underway, such as extreme heat waves<\/strong> and flooding<\/strong>. The logic is simple: those who have contributed more to the crisis must share more in the costs of adaptation<\/strong>. <\/p>\n\n

The availability of detailed data is also crucial for climate attribution, that discipline that quantifies the link between individual events or trends and specific emission sources. A study published in Nature <\/em>in September 2025 estimated that so-called“carbon majors<\/strong>” contributed half of the increase in heat wave intensity compared to the period 1850-1900. This is not only a widespread responsibility, it is a measurable one. <\/p>\n","protected":false},"excerpt":{"rendered":"
