The aim of the study is to determine the carbon footprint of York residents and show how this varies throughout the city. It builds upon a 2002 study to assess the ecological footprint of York. A number of factors can shape and constrain an individual's decision to lead a greener lifestyle. While there may be a willingness to undertake green actions, individuals are waiting for an enabling and supportive structural framework. The study identifies those York neighbourhoods that have the greatest potential to reduce their carbon footprint. Based on carbon footprint data for each neighbourhood, attitudes of residents to green issues and the availability of local infrastructure it allows a more targeted approach to be a taken to reduce residential carbon emissions in York. Annex I provides a detailed explanation of the methodology used in the study.
