The Association of European Rail Rolling Stock Lessors (AERRL), with support from Akiem, Beacon, Cargounit, Crédit Agricole CIB, ING, KfW IPEX-Bank and Societe Generale has launched the first phase of a study to identify and promote technologies to cut the climate impact of existing diesel-powered rail fleets in the near future. Although rail is already by far the most sustainable mode of land transport, this initiative aims to help rail transport on non-electrified lines transition to low-carbon technologies that provide even greener passenger and freight transport.
