Travel & transport: how far can we go on renewables? - preview
Sometimes there is a slight smell of chips frying around my car, when it is running on recycled vegetable oil
  • Using plant-based waste products must be among the best ways to cut carbon dioxide (CO2) emissions from driving a car
  • However, even if we persuade people to eat more chips, the supply of recycled cooking oil will be quite limited
  • So how much can renewables and technology contribute to greenhouse gas emission reductions?

    In the UK, burning transport fuels (for passenger and freight transport by land, sea and air) produces about sixty million tonnes of CO2 (about one quarter of all UK emissions)
  • Roughly half of this comes from cars, one quarter from road freight and one quarter from aviation
  • Nitrogen oxides and water vapour emitted by aircraft at high level add considerably to the global warming impact of their CO2 emissions, roughly tripling the effect
