Methods & Results Rpt (MRR) and Worksheets


The Methods and Results Report (MRR) is a comprehensive discussion of the methodology, process of gathering and analyzing the production data, and estimating the emissions for each Carbon Major entity. The MRR was written by Richard Heede (Principal of Climate Mitigation Services), peer-reviewed by experts in the carbon inventory field, and published on 7 November [...]

New Study Traces Two-Thirds of Industrial Emissions to Just 90 Institutions

New peer-reviewed research has found that just 90 entities are responsible for extracting most of the fossil fuels that have been burned over the past 150 years. These “carbon majors” include 50 investor-owned companies, such as Chevron and Exxon-Mobil, 31 state-owned companies, such as Saudi Aramco and Pemex, and nine government-run industries in the former [...]

Welcome to the Carbon Majors Website

The Carbon Majors website is based on ground-breaking research on 90 entities (investor-owned, state-owned, and government-run fossil fuel and cement producers) that are responsible for producing the fuels that have resulted in 63 percent of the global cumulative emissions of industrial carbon dioxide and methane between 1751 and 2010.
