"New clean diesel technology across all applications has now transformed to achieve near-zero emissions, while still maintaining an efficiency advantage over other energy sources. "As we work toward a sustainable future, the utilization of advanced renewable diesel fuels enhances all diesel performance and ensures diesel's long-term suitability for helping achieve environmental, energy, climate and sustainability goals of nations, states, cities and fleets." Renewable Diesel Lowers GHG Emissions by 40-90 Percent Renewable diesel fuel produced by companies like Neste Corporation is made from 100 percent renewable raw materials and results in a 40-90 percent reduction in greenhouse gas emissions over the fuel's lifecycle when compared with traditional fossil diesel. Cities like San Francisco and Oakland have transformed their fleets to renewable diesel as a cost-effective policy to immediately lower emissions in their regions.
