Encouraging sustainable modal shift – an evaluation of the Portsmouth Big Green Commuter Challenge

Research output: Contribution to journalArticle

This paper describes the impact of the Portsmouth "Big Green Commuter Challenge" (BGCC) event, organized by Portsmouth City Council (PCC) in order to reduce carbon and nitrogen oxide emissions from transport within the city. In total, over 1000 people and 36 organizations took part in the 2011 event. This is an example of a ‘Smarter Choice” measure designed to encourage travel behavioral change to more sustainable modes of transport. A literature review and evaluation of previous “Smarter Choices” measures has been carried out to give some context to the BGCC. An introduction to the city of Portsmouth is presented, in particular its efforts to reduce road traffic and emissions from the city centre area. The event encouraged a modal shift to more sustainable modes of travel, resulting in estimated reductions in CO2 and NOx emissions per mile. However, a number of further recommendations have been made to enable future similar events to have a greater impact on road traffic and emissions.
