Memorandum for the Petitioners 1115 1,023 GtC02, or 66% of all anthropogenic CO2 from 1751 to 2016; The direct and product-related emissions of the 50544 investor-owned companies total 368 GtC02e (21.4%), the 36 state-owned companies total 357 GtCC e (20.8%), and to government-run industries total 408 GtC02e (23.8%); historical emissions not traced to the 90 Carbon Majors total 585 GtCC e (34%); c) ^ ^ d) The carbon fuels produced by the top twenty investor-owned fossil fuel companies contributed to 30% of all global industrial C02e from 1751 to 2016; The carbon fuels produced by the e) investor-owned fossil fuel companies contributed to one-third of all global industrial C02e from 1751 to 2016; and r f) Half of all industrial CO2 emissions since 1751 have been emitted since 1989.545 r 8.126. According to Mr. Heede, respondents Royal Dutch Shell, Chevron, Statoil , Total, Hess, BP, and ConocoPhillips do estimate and submit to the carbon accounting non-profit organization Carbon Disclosure Project (“ CDP” ) their product-related emissions (respondent ExxonMobil only estimates emissions for products sold in New Zealand, USA, and Quebec).546 Although each company’s methodology differs, they are roughly comparable to Mr. Heede’ s internally consistent methodology 547 CDP and CAI collaborated on a “guidance methodology report for calculating emissions from carbon production by fuel.»548 , 8.127. Significantly, though not subsequent to Mr. Heede’s results, respondent Shell estimated in a 1988 confidential report,549 which came to See supra note 17.
