  • Planes

        • Flights of green fancy
        • Air travel shows no sign of losing its allure but its environmental impact is not going to go away. Katharine Sanderson looks at some of the ways that scientists and engineers hope to reduce the carbon wing-print of aircraft.

  • Cars

        • Four wheels good?
        • With the world's love of cars showing little sign of abating, manufacturers are under increasing pressure to make vehicles less polluting and oil dependent. Duncan Graham-Rowe explores some of the technologies that could keep us on the road.

  • Ships

        • Whatever floats your boat
        • Shipping is one of the most fuel-efficient ways to move freight, but the industry still produces significant greenhouse-gas emissions, including more than a quarter of the world's nitrogen oxides emissions. And it also produces more sulphur dioxide emissions than all land transportation combined. In the latest of our Future Transport series, Duncan Graham-Rowe looks at the new wave in shipping.

  • Trains

        • Do the locomotion
        • Rail travel produces more than a third less emissions than road transport — even though trains carry 7% of traffic, they emit just 0.2% of the carbon monoxide, 2% of nitrogen oxides and 1% of the volatile organic compounds. Although electric passenger trains are relatively green, most of the world's trains are used for haulage and run on diesel. In the latest of our Future Transport series, Duncan Graham-Rowe sees trains switching to a greener track.
