This paper summarises the work of the VIBAT London study, simulating the different policy pathways towards carbon efficient transport in London.
Transport is a major user of carbon-based fuels, and is increasingly being highlighted as the sector which contributes least to CO2 emission reduction targets. This paper reports on the findings of the current VIBAT London study (www.vibat.org) which considers the role of the transport sector in reducing CO2 emissions in
The study develops an inventory of policy packages available to reduce carbon emissions and a transport and carbon simulation game (TC-SIM) for London. Within this, users are able to consider a series of potential
policy packages including low emission vehicles, alternative fuels, pricing regimes, public transport, walking
and cycling, strategic and local urban planning, information and communication technologies, smarter choices,
ecological driving and slower speeds, long distance travel substitution, freight transport, and international air
and select variable levels of application to help achieve headline CO2 emission reduction targets. The roles of
two external enabling measures are also considered ? carbon rationing and oil pricing.
TC-SIM can be played in different user modes: as enviro-optimists, free riders, concerned realists, technooptimists,
and complacent car addicts or even as a free role ? helping to highlight the wide variety of
viewpoints and perceptions in transport futures planning.
The paper develops various policy packages and pathways towards reduced CO2 emissions in London and
argues that we need to act more effectively across a wide range of policy mechanisms. The policy choices
available also need to be well communicated, to stakeholders and the public, if we are to move towards
adopted targets for transport carbon emissions.
