Decarbonizing Combustion Vehicles: A Portfolio Approach to GHG Reductions

Date: July 5, 2023 PDF: 19.5 KB

Reducing greenhouse gas (GHG) emissions from internal combustion engine vehicles (ICEVs), while transitioning to zero-tailpipe emissions vehicles (ZEVs), will deliver the greatest environmental benefits in both the near- and long-term. This report evaluates the viability and emissions reduction potential of a variety of technology and energy options that can benefit the ICEV market and concludes that adopting a portfolio approach that matches low carbon strategies with different vehicle types and use cases is the most effective path for decarbonizing the transportation sector.   

The report presents a portfolio of options available to policymakers and market leaders seeking to achieve meaningful emissions reductions from the transportation sector. The report evaluates: 

  • The benefits and importance of early GHG reductions considering the atmospheric life of GHGs and the slow pace of fleet turnover 
  • The life cycle emissions of various ICEV energy options 
  • The low carbon potential, scalability and feedstock availability of biofuels 
  • The factors that will affect the market’s transition to each evaluated option 

While there is no silver bullet to the reach immediate carbon reductions, there are many near-term opportunities in the goal to reach net-zero. This report is an extensive look at the challenges and practical approaches that can be taken to address emission reduction in all vehicles.
