||This strategy document sets out the policies and proposals for reducing transport sector emissions through to 2022. Transport currently makes up 21 per cent of all UK domestic carbon emissions. Carbon emissions from domestic transport will be reduced by up to 14 per cent over the next decade. The strategy outlines how an additional 85 million tonnes of CO2 from domestic transport can be saved from 2018-2022 by: supporting a shift to new technologies and fuels; promoting lower carbon choices; and, using market mechanisms to encourage the shift to lower carbon transport. On the roads, vehicles will be vastly more fuel-efficient by 2022. This will primarily be delivered through advances in the efficiency of the internal combustion engine. Alongside this, new ultra-low emission vehicles will have made their transition onto the mass-market. On the railways electric trains offer better environmental performance than diesel equivalents and can also increase capacity and reliability, as well as being cheaper to buy, maintain and operate. There is a good case for electrifying more of the rail network and the Government will announce plans shortly.Aviation and shipping are being encouraged to exploit the full potential of technology to improve fuel efficiency and reduce emissions. The Government will also promote: the use of sustainable biofuels; public transport as an accessible, attractive, low carbon and easy-to-use option for individuals and business; better coordination and integration of different services; and, the use of trading systems to reduce emissions in aviation and shipping.
