Heavy trucks responsible for 4/5 of total fuel use
Heavy trucks, which are used for long-haul transports and known for their fairly low fuel economy, are responsible for the lion's share of road transport emissions. We were able to reduce these emissions by optimizing aerodynamics, modifying engine control systems, using alternative drive systems and fuels and special driver training programs. Our fleet in England, for example, is already fitted with 1,001 aerodynamic "teardrop" trailers; we also intensified the use of natural gas within our US fleet with the investment of 22 natural gas trucks.
