Personal transport
Personal transport accounts for 20% of half is due London’s CO2 emissions, of which 9% to car travel and the remainder is split between air travel and public transport.10%The table below illustrates the baseline CO2 emissions from personal transport. About half of the impact of 12% car travel is due to direct fuel emissions, but the rest is due to buying and maintaining vehicles. Built infrastructure

In the case of transport, it is difficult to unpick the consumption-based emissions used in this model from the territorial emissions used in the London Climate Change Action Plan. The consumption emissions modelled here are for London residents and so will include transport emissions outside London when Londoners leave town. The CCAP models all transport emissions that occur within London, whether they are attributable to London residents, workers or other visitors. The other difference between the two models is that the consumption-based emissions modelled here include the embodied emissions from manufacturing vehicles, buses and trains. Figure 19 shows a combination of measures that deliver the CO2 savings required. They include successful delivery of the London Climate Change Action Plan, significant reductions in air travel, widespread provision of car clubs and a long-term shift towards electric cars. The detail behind the modelling is set out in Table 15 of Appendix A.
