CN announces enhanced calculator to estimate greenhouse gas-emissions for multi-modal shipments

Canadian National unveiled an upgraded online greenhouse gas-emissions calculator that estimates total carbon emissions for shipments across multiple modes of transportation. The new calculator, located at http://www.cn.ca/ghg_calculator, generates carbon-emission estimates for shipments using a combination of vessel, rail and truck - such as containers moving internationally from Asia to North American destinations along CN's network - or domestic shipments using a combination of rail and truck or a single mode of transportation.
