The ACT Expo 2025 kicked off with a keynote address by Cummins Chair and CEO Jennifer Rumsey, setting the stage for a dynamic and unpredictable phase in the clean transportation industry. The keynote highlighted the challenges posed by regulatory uncertainty and shifting incentives but called for continued innovation and investment in cleaner, more efficient technologies. The industry's progress in reducing emissions and improving fuel efficiency was celebrated, with a focus on various solutions including battery electric, fuel cell, hydrogen, and advanced diesel engines. Rumsey outlined essential actions for the industry, emphasizing the importance of smart regulations, considering life cycle emissions, and driving continued innovation to achieve greenhouse gas reductions and economic value. Real-world examples from fleets like WM, UPS, and Gazelle Transportation demonstrated the success of natural gas vehicles and advancements in hybrid technologies. Electric vehicle adoption, particularly in specific applications like school buses, was highlighted, with the need to reduce total cost of ownership for broader market adoption. Cummins' partnership with key players to manufacture lithium iron phosphate battery cells in the U.S. aims to strengthen domestic electrification infrastructure. The keynote concluded with a call for collaboration, flexibility, and a commitment to progress to navigate the complexity of the road ahead towards a more prosperous and sustainable future for transportation.
