ExxonMobil is exploring innovative fuel blends with the potential to reduce greenhouse gas emissions from road transportation up to 75% compared to conventional fuels available today.

The U.S.-based energy major is teaming up with Japanese automaker Toyota Motor Corp. to test fuels with a lower carbon footprint. 

Estimates of reductions in carbon intensity (CI) are based on the lifecycle greenhouse gas emission of the fuels tested at Toyota’s Research Center, compared to petroleum gasoline. 

Estimated CI values are based on either GREET 2021 estimates, or feedstock Proof of Sustainability documents.  

GREET (Greenhouse gases, Regulated Emissions, and Energy use in Technologies) is a life-cycle analysis (LCA) tool, structured to examine systematically the energy and environmental effects of a wide variety of transportation fuels and vehicle technologies in major transportation sectors (i.e., road, air, marine, and rail) and other end-use sectors, and energy systems.

Toyota said it has determined that these innovative formulas are compatible with older vehicles, as well as its current model line-up. These lower carbon fuels are also compatible with existing fueling infrastructure.

Both companies agree that multiple solutions and supportive policies are required to reach a lower emission future for transportation.
