About 90% of the environmental impact caused by a conventional diesel powered bus arises when it is on the road. In order to reduce the environmental impact of our products, we are working on a number of fronts. Product development focuses both on reducing emissions of air pollutants and on reducing fuel consumption. Over the past twenty years, emissions of hazardous compounds in the exhaust fumes have been reduced by between 60% and 85%. At the same time, fuel consumption and carbon dioxide emissions have been cut by about 30% for heavy buses.

Consistent and uniform environmental work
In order to ensure that environmental work is consistent and uniform, environmental control systems are being swiftly introduced throughout Volvo. So far, six of Volvo Buses' plants and units have been certified according to ISO 14001. Operations at Volvo Buses' production facilities are regularly inspected by an audit team under the leadership of the Group Environmental Auditor.
