Visioning and Backcasting for Transport Policy in London (Vibat London)

The Vibat London study examines the possibilities of reducing transport emissions in London by 60 per cent to 2030 and 80 per cent to 2050 through a modified backcasting and scenario-building approach. It is a knowledge transfer project funded by UrbanBuzz.PPS and segmentation

It examines a range of policy measures (technological and behavioural), and assesses how they can be effectively combined to achieve these levels of emissions reduction. The intention is to assess whether such ambitious target are feasible, identify the main problems (including the transition costs), and the main decision points over the future time horizons.

Different levels of application of a range of policy packages can seek to meet strategic aspirations and targets.

Funder: UrbanBuzz Programme

UrbanBuzz: Building Sustainable Communities is a 2-year knowledge transfer programme (running from 2007-09) that aims to develop new ways of delivering sustainable forms of development and community in London and the wider South East region. University College London (UCL) and University of East London (UEL) are the co-originators and facilitators of UrbanBuzz.

Note. This study has been carried out as a piece of independent research using data kindly supplied by Transport for London (TfL), Greater London Authority (GLA) and others. The views expressed in the study are, of course, from the authors and do not necessarily reflect those of UrbanBuzz, TfL or the GLA. TfL has developed and uses its own transport and CO2 models.
