Early warnings and emerging accountability: Total's responses to global warming, 1971-2021

Christophe Bonneuil et al.

Summary: The study reveals that Total was warned about the potential for global warming from its products as early as 1971, and began promoting doubt regarding the scientific basis for global warming in the late 1980s before ultimately accepting climate science publicly in the late 1990s while pushing for policy delay. Exxon, through IPIECA, coordinated an international campaign to dispute climate science and weaken international climate policy starting in the 1980s.
