CATCH. ECOtravel and Clean Buses on Merseyside

By News Editor / Updated: 29 Aug 2014

CATCH (Clean Accessible Transport for Community Health) was an EU funded demonstration project which aimed on the promototion of sustainable mobility in order to improve air quality on Merseyside. CATCH was finished at the end of 2005


CATCH (Clean Accessible Transport for Community Health) was a demonstration project in the European Commissions Life-Environment Programme promoting sustainable mobility in order to improve air quality. CATCH was being implemented in Liverpool (UK), Suceava (Romania) and Potenza (Italy).

The beneficiary was Merseytravel, the Partners were: Liverpool City Council, Arriva North West and Wales Ltd, CTP Napoli (Italy), Suceava Municipality (Romania), and Transport and Travel Research Ltd (TTR). The main finances came from the EC Life-Environment Programme (€1.48m) and the project was co-financed by the Energy Savings Trust.


The project was split into 10 separate tasks (covering implementation of measures in Liverpool, Suceava and Potenza) and general tasks

  • Emissions Reduction - Existing Vehicles: The installation of particulate traps on 104 buses in Liverpool with additional exhaust gas recirculation equipment on 16 of these.
  • Emissions Reduction - New Vehicles: The initiation of a city centre shuttle route operated by 6 hybrid buses.
  • Air Quality Management: Declaration of a formal Air Quality Management Area in Liverpool city centre and an associated Air Quality Action Plan.
  • Working with the Market and Citizens: The establishment of a shop for sustainable travel information in Liverpool , known as ECOtravel.
  • Pollution Monitoring: The development, implementation and testing of advanced pollution monitoring techniques in Liverpool
  • Evaluation: Evaluation and reporting of the impacts of CATCH
  • Transferability to Candidate Countries: Implementation of a package of measures to improve air quality in Suceava, including:
  • 1) The closure of a section of one of the main streets in Suceava and it transformation into a pedestrian-only low emission zone
  • 2) Purchase of two LPG cars by Suceava municipality that have been used in day-to-day public activities and in the promotion of clean fuels in the city
  • 3) Extensive public promotion of sustainable travel options in Suceava
  • 4) The refurbishment of 10 trolleybuses in Suceava leading to the removal from service of old polluting buses
  • >
    • Transferability to Southern Europe: Investigation of measures to improve air quality in Potenza, focusing on a feasibility study and recommendations for the introduction of a limited traffic zone in the town of Potenza
    • Dissemination: Dissemination to ensure that CATCH has the highest possible profile within its public sector target group at local, national and international levels
    • Project Management: All activities required to keep the project to time and budget and the client informed.


    The local air quality benefits of the project have been demonstrated in terms of the significant emissions reductions delivered by the project measures and the even greater potential for wider implementation of these measures. In particular, CATCH has contributed annual savings in emissions in Liverpool of 3.9 tonnes of NOx (equivalent to 1.6% of NOx emissions in city centre) and 3.2 tonnes of particulates (equivalent to 22.2% of particulate emissions in city centre), these being the two pollutants causing greatest concern in terms of local air quality.
    The project measures also show the potential to deliver further emissions reductions in Liverpool, if implemented more widely. CATCH has also delivered emissions savings in the city of Suceava and developed a plan for a limited traffic zone in Potenza which would lead to substantial emissions reductions in that city.

    Another direct impact of the project in Liverpool has been an increase in CO2 emissions of 279 tonnes per year, but the project evaluation shows that a wider implementation of the project measures would actually result in a reduction in CO2 emissions of 50939 tonnes per year assuming implementation of effective, wider behavioural communications campaigns based on the CATCH healthy travel promotion and replacement of the oldest vehicles operating in Liverpool’s bus fleet with hybrid buses which can deliver the CO2 savings that have been demonstrated under laboratory conditions.
