Heavy goods vehicles

At 30g CO₂ per passenger kilometre the express coach is the most carbon efficient form of motorised transport resulting in less than a quarter of the emissions per passenger than equivalent journey by car. Average number of people in a car is just 1.58, compared to 32 on a coach. Congestion dramatically increases CO₂ emissions from road vehicles. Under heavily congested conditions tail pipe emissions can be increased by as much as 3 or 4 times. Click here to compare CO₂ emissions from different modes of transport over various journeys.

This heavy-duty diesel lorry utilises Clean Air Power’s Dual-Fuel technology to deliver significant greenhouse gas emission reductions and fuel cost savings compared with standard diesel engines. These Dual-Fuel trucks are around 30% more energy efficient than equivalent spark ignited natural gas engines. The engines can use natural- or bio-gas as the main fuel and can also operate on only diesel, an important feature as gas distribution systems face many years of development.

In the UK, a typical truck operator can save around £15,000 a year from retrofitting Dual-Fuel technology which represents a payback on investment of around two years. Volvo is opening a production line for Euro V compliant engines incorporating this technology - they can run on either compressed (CNG) or liquid natural gas (LNG).

The 2011 Bridgestone Eco-Rally convoy includes a Stagecoach double-decker bus with cutting-edge electric hybrid technology. The hybrids are smoother for passengers, quieter for pedestrians and emit ~30% less carbon, particulates and NOx than a standard vehicle. They operate at Park & Rides and on some of the busiest city centre routes. By switching just one journey in twenty-five we can remove 1 billion car journeys from our roads, and avoid 2 million tonnes of CO₂. In addition, new research proves that taking the bus rather than the car can reduce mental stress by a third.

Haulier Harry Wragg is upgrading his food haulier fleet to be powered by CO2 nuetral, renewable fuel - grown in the field just like the foodstock it carries. Sixteen award-winning Mercedes Actros lorries have been converted by Elsbett from new to operate on Verdant Fuel (made from European-sourced rapeseed oil).
