Four years later, global emissions still increased: by 1.7% in 2017, and a further 2.7% in 2018. Under the Paris Climate Agreement of 2015, 196 countries committed to taking steps to limit the rise in global temperature this century to well below 2 degrees Celsius. During this period, while some noted oil giants and household names chose climate change denial and funded organizations that questioned climate scientists, others transitioned from being called an oil or coal producer to an “energy” company, projecting a cleaner profile. Half of these emissions were produced in the past 25 years, when globally, the awareness of climate change, GHGs, global warming, and rising sea levels has increased. The top emitter was China’s state-owned coal and cement production company. Unsurprisingly, the companies most responsible for climate change included Saudi Aramco, Chevron, ExxonMobil, BP, Gazprom, and National Iranian Oil Company-companies spread across the Middle East, Europe, Russia, and the United States. The remaining are cement and building material manufacturing companies. Each slide also summarizes the best practices employed by the company and the country to reduce emissions and move toward a sustainable future.Ĭoal, oil, and natural gas are produced by 83 of these companies. All values included in this story are taken from estimates using the “best,” or middle scenario, the model described in Millar et al. In its study, the research team wrote that “the emissions traced to these 90 carbon producers contributed ∼57% of the observed rise in atmospheric CO2, ∼42–50% of the rise in global mean surface temperature (GMST), and ∼26–32% of global sea level (GSL) rise over the historical period, and ∼43% atmospheric CO2, ∼29–35% GMST, and ∼11–14% GSL since 1980.” Stacker analyzed the study to rank the largest emitters by their atmospheric carbon dioxide contributions from 1880 to 2010.
The news comes in stark contrast to efforts to slow down the pace of global warning-and amid several of ExxonMobil’s competitors, including BP Plc and Royal Dutch Shell Plc, announcing plans to reach net-zero emissions.ĭespite the onus put on consumers to reduce their carbon footprints, just 90 companies around the world have been responsible for nearly two-thirds of greenhouse gas (GHG) emissions from 1880 to 2010, according to a 2017 Climate Change study by Brenda Ekwurzel of the Climate & Energy Program at the Union of Concerned Scientists and a team of researchers. ExxonMobil, the fifth-leading producer of greenhouse gas emissions in the world from 1880 to 2010, has been planning since 2018 to raise its yearly carbon dioxide emissions by as much as 17% by 2025, according to internal documents reviewed by Bloomberg.
