Transportation is the largest source of direct greenhouse gas emissions in the United States. The sector is undergoing rapid transformation. New technologies are creating powerful opportunities to reduce emissions and accelerate the shift to a low-carbon transport system. Manufacturers, fleet operators, and customers each play a critical role in advancing this transition. As clean transportation gains global momentum, companies that lead today will be better positioned to remain competitive, create long-term value, and drive meaningful climate impact. 

Areas of Focus 

• Electrification of vehicle fleets: Advances in battery technology have made large-scale electrification more viable than ever. Our work engages companies across a wide range of fleet types, from long-haul to last-mile delivery, supporting efforts to evaluate forward-looking policies, pilot emerging technologies, and invest in strategies that align with long-term sustainability goals. These actions can reduce operating costs, strengthen resilience, and significantly cut emissions across supply chains. 

• Decarbonizing aviation: Aviation remains a challenging sector to decarbonize, yet the urgency for action is clear. Engagement across aircraft manufacturers, airlines, and other aviation stakeholders focuses on reducing full lifecycle emissions, improving transparency, and accelerating the development of cleaner technologies. Strengthening accountability and innovation in this sector is essential for achieving a low-carbon future for air travel.
