How cruise control can decarbonize US railroads

Norfolk Southern, a major U.S. railroad, aims to cut emissions by 42% by 2034, focusing on biodiesel and renewable diesel. The company has seen a 12% reduction in emissions per ton-mile and improved fuel efficiency by 5% in 2025. Norfolk Southern's 'book and claim' scheme allows customers to purchase emissions savings certificates. A proposed merger with Union Pacific could further reduce emissions by shifting freight from road to rail, but critics express concerns about service and pricing.
