  1. Clean Accessible Transport for Community Health Evaluating the CATCH Project www.cleanaccessibletransport.com Alan Lewis, Transport & Travel Research Ltd

  2. Introduction • Evaluation is governed by the project objectives & expected results. i.e.: • Promote partnership working • Improve urban air quality • Reduce greenhouse gas emissions • Expand use of clean fuels in public transport & local authority fleets

  3. Partnership Working • Ensuring relevant partners are included at the start is imperative to ensure delivery • Institutional framework has a massive impact in determining outcomes • Regulations and guidance help reinforce the message but must be backed up by communication & action

  4. Technical Solutions: Air Quality • Particulate filters on older buses have been extremely effective: • Particulates down 80-95% • CO down 90% • Hydrocarbons down 90% • NOx reduction technologies promise a way of completing the job: • EGR 30-50%, SCR more….?

  5. Technical Solutions: Air Quality • Without forcing a massive fleet renewal, could reduce: • Bus particulate emissions (25% of the total) by a further 40% • Bus NOx emissions (47% of the total) by a further 18%

  6. Air Quality vs Greenhouse Gases • Often find technologies that can address only one of air quality or greenhouse gas emissions at reasonable cost • The hybrid buses now being trialled offer a technical opportunity to address both • But who pays the price in the commercial world?

  7. The Importance of Public Behaviour Change • Cars contribute the majority of CO2 emissions from transport in Liverpool city centre (and elsewhere for ground-based transport) • LCC have trialled 2 hybrid cars to demonstrate a technical improvement • But transfer to other modes (walking, cycling & public transport) gives a much greater impact on CO2 and helps further cut other emissions

  8. Efforts to Influence Behaviour • General awareness raising is first step… • Planning activities and can help influence travel decisions through parking and access restrictions • Partnership working with developers and community groups could have much greater impact than has been seen to date in the city • Fleet managers appear to have good awareness, but are subject to commercial pressures
