ExxonMobil, the U.S.'s largest oil producer, has not made a commitment to reduce its absolute level of greenhouse-gas emissions, as many companies and governments have. The company instead has said it will reduce the “intensity” of certain emissions relative to previous levels. As intensity is a relative measure, emissions in absolute terms could still increase as overall output increases.
“To tackle climate change total emissions must go down so an absolute reduction is the most relevant measure,” Australia's Climate Council says.
Exxon's emissions goals are framed similarly to those of its no. 2 U.S. rival, Chevron. Both focus on ”upstream” production, accounting for between 5% and 37% of overall fossil-fuel emissions. Their strategies contrast with those of major European producers committing to absolute reductions, and often more explicit shifts away from fossil fuels.
