Title: Achieving 80% Reduction in Transport Greenhouse Gas Emissions, Using The USA as a Case Study
Abstract: This paper will investigates the potential for reducing United States (US) transportation greenhouse gas (GHG) emissions in the long term (50-80% below 1990 levels by 2050). The paper uses scenarios to envision how such a significant decarbonization might be achieved with changes in vehicles, fuels, and vehicle use. A Kaya framework that decomposes GHG emissions into the product of four major drivers is used to analyze emissions and mitigation options. All major transportation activities are included in this paper—cars and trucks, aviation, rail, marine, agriculture, off-road, and construction. The authors confirm the notion that a portfolio approach is needed to achieve deep cuts in transport. Light duty vehicles offer the greatest potential for emission reductions. Deep reductions in other subsectors are also possible, but are more limited in the types of fuels and propulsion systems that can be used. Reduced travel demand will help to reduce emissions.
