Highways Agency
• Consists of 7,000km of motorways and all purpose trunk roads
• Largest government owned asset valued at over £85 Billion
• It carries one-third of all traffic and two-thirds of all freight on just 3% of all roads in England
Climate Change and the
Highways Agency
• Mitigation: reduce our contribution to the causes of climate change
Adaptation: adapts to continue to provide a robust strategic road network in a changing climate
Climate Change Mitigation and
the Highways Agency
• UK Government’s commitment to the reduction of greenhouse gases
• Highways Agency obligation to manage and contribute to reduction targets
• Business Plan 08-09 commitment to report carbon footprint
Carbon Accounting - Process
Overview“You can’t manage what you can’t
measure”
• September 2008 - Interim Advice Note 114/08 (standard) requirement for all major suppliers to report on carbon emissions associated with delivering our work
• Excel based system that asks for quantities of resources used, and calculates CO2 based on standard conversion factors

Highways Agency –
Carbon footprint 2008-09
• In region of 550,000
tonnes/CO2 associated with:
• Major construction
• Maintenance and improvement
• HA office and business travel
• Network energy consumption
Published in our annual report for
the first time
Mitigation: CO2 reductions -
Midnight switch off
• At current energy rates the project is expected to pay for itself within four years
• No evidence of an increase in accident rates. Evidence has suggested the accident rate may have dropped while the sites have been active.
• The site selection of additional Phase 2 deployment has begun, which will probably increase the anticipated 400 tonnes of CO2 savings already expected by the end of this year.
Mitigation - manage traffic
flows to reduce congestion
• Enhance capacity where necessary
• Use technology to help traffic flow more smoothly
• Deploy demand management measures:
- High Occupancy lanes
- Ramp Metering
- Travel Plans
• Influence land use development
Mitigation: better information
to improve user decisions
• Most road traffic decisions made by users & CO2 produced from users actions
• Better information about options and route condition
• Internet tools
• Traffic Radio
• Telephone enquiry
• On route electronic message signs
Day After Tomorrow…
• Business Plan targets 2009-10
• Reduce emissions from main HA offices and administrative business travel
• Reduce emissions from energy supply for network lighting
• Factor climatic changes into standards and specifications
• Apply procurement strategy
