News Update – 11 July 2017
Press Release: CAI, in collaboration with CDP, announces the publication of Carbon Majors Dataset 2017 of operational and product-use emissions attributed to one hundred major oil and gas and coal companies over the period from 1988 to 2015. The Dataset includes a Methodology Report and an Excel workbook of Scope 1 (Operational) and Scope 3 (product-related) emissions attributed to major fossil fuel producers around the world.

News Update – 10 March 2017
CAI, in collaboration with CDP (London), announces the publication of operational and product-use emissions attributed to fifty major oil and gas companies over the period from 1988 to 2015.
The Climate Accountability Institute and CDP jointly announce the publication of the Carbon Majors Dataset. The Dataset points to the central role of the oil and gas sector in global carbon dioxide emissions and highlights the risks and opportunities of the industry to drive the transition to a low-carbon economy. The Dataset updates the Carbon Majors database of operational and product-use emissions attributed to the largest fifty investor and state-owned oil and gas companies from 1988 to 2015. This updates the original work by Richard Heede (2014) Tracing anthropogenic CO2 and methane emissions to fossil fuel and cement producers 1854-2010, Climatic Change, vol. 122(1):229-241; URL: http://link.springer.com/article/10.1007/s10584-013-0986-y?view=classic.
