â¢ Take action to increase average road vehicle occupancy by 2030 and reduce the barriers to data sharing across the transport sector. â¢ Maximise carbon savings from the use of low carbon fuels, including by increasing the main Renewable Transport Fuel Obligation (RTFO) target. â¢ Increase the share of journeys taken by public transport, cycling and walking. â¢ Support decarbonisation by investing more than Â£12 billion in local transport systems over the current Parliament. â¢ Invest Â£2 billion in cycling and walking, building first hundreds, then thousands of miles of segregated cycle lane and more low-traffic neighbourhoods with the aim that half of all journeys in towns and cities will be cycled or walked by 2030.
