Dictionary meaning
the process of eliminating or substantially reducing greenhouse gas emissions from freight rail operations, which currently rely predominantly on diesel locomotives and account for a significant share of transport sector emissions globally; decarbonization pathways include electrification of rail corridors using overhead catenary or third-rail systems, hydrogen fuel cell locomotives for routes where electrification is economically impractical, battery-electric and battery-hybrid locomotives, and the use of biodiesel or synthetic fuels as transitional measures; freight rail is widely regarded as the most energy-efficient surface mode for long-distance cargo transport, and its decarbonization represents a high-leverage opportunity to reduce logistics sector emissions while maintaining economic competitiveness with road freight
