Clean vehicle programme

Sustainability case study

Heathrow’s Clean Vehicle Programme (CVP) was established in 2003 and is designed to help reduce nitrogen oxide (NOx) and carbon dioxide emissions (CO2) from vehicles used within and around Heathrow.

The CVP aims to reduce vehicle CO2 emissions, by:

  • Cutting mileage or hours driven
  • Improving vehicle fuel economy
  • Introducing cleaner, low emission vehicles
  • Reducing the number of commuter journeys that employees make by car.

Forty-seven companies operating at Heathrow have joined the programme, including 26 with fleets of over 30 vehicles.

Those with large fleets complete a self-assessment to identify steps they can take to improve performance. These include tracking mileage, fuel use and driver training.

The CVP collates data and tracks improvements over time. Member companies set performance targets and develop an action plan outlining how they intend to meet them. Periodic audits of vehicle emissions by an independent expert check whether emissions are being reported correctly and can also advise on ways to reduce them.

In 2010, seventeen CVP members submitted an annual vehicle self assessment.  The companies reported the average fuel economy of their ground vehicles at Heathrow falling by 6% compared with the previous year.




  • Number of members: 47
  • Number with fleets of over 30 vehicles: 26
  • Number completing self assessments in 2010: 17
  • Number of vehicles involved: 2,533
  • Number of miles travelled: over 37 million
  • Fuel economy improvement (2009/2010 average of 17 companies): 6%
  • Number of drivers completing Smarter Driving training: 12,000, with average reduction in fuel consumption during training of 14.8%
  • Improvement of the capabilities of drivers at Heathrow
  • Reduced local air pollution and traffic congestion.
