Exxon’s Plan for Surging Carbon Emissions Revealed in Leaked Documents

Exxon Mobil Corp. had plans to increase annual carbon-dioxide emissions by as much as the output of the entire nation of Greece, an analysis of internal documents reviewed by Bloomberg shows, setting one of the largest corporate emitters against international efforts to slow the pace of warming.

The drive to expand both fossil-fuel production and planet-warming pollution has come at a time when some of Exxon’s rivals, such as BP Plc and Royal Dutch Shell Plc, are moving to curb oil and zero-out emissions. Exxon’s own assessment of its $210 billion investment strategy shows yearly emissions rising 17% by 2025, according to internal projections.

The internal estimates reflect only a small portion of Exxon’s total contribution to climate change. Greenhouse gases from direct operations, such as those measured by Exxon, typically account for a fifth of the total at a large oil company; most emissions come from customers burning fuel in vehicles or other end uses, which the Exxon documents don’t account for.

That means the full climate impact of Exxon’s growth strategy would likely be five times the company’s estimate—or about 100 million tons of additional carbon dioxide—had the company accounted for so-called Scope 3 emissions. If its plans are realized, Exxon would add to the atmosphere the annual emissions of a small, developed nation, or 26 coal-fired power plants.
