The report draws from the findings of the VIBAT London study (Visioning and Backcasting for Transport in London). The study considers the pathways towards a 60% reduction in transport CO2 emissions by 2025 and 80% reduction by 2050 on 1990 levels. London is used as a case study and a simulation model of the city is developed to examine and test potential future scenarios for different levels of application of different policy packages.

Urban Graphics was commissioned to design, print and manage the 20 Percent Transport - Visioning and Backcasting for transport in London document.
