Valero has achieved significant emission reductions and invested in producing cleaner-burning gasoline, diesel and ethanol-blended fuels. For example:
-
Valero has invested more than $1 billion at refineries in environmental updgrades such as new-generation flue-gas scrubbers, including the world's largest such facility at its Benicia Refinery, and flare-gas recovery systems that dramatically reduce emissions.
-
Valero’s low-sulfur gasoline and diesel program not only reduces sulfur emissions from cars but allows new automobile technology to reduce emissions of nitrogen oxide and hydrocarbons.
