London - sustainable transport - hybrid buses

Diesel-electric hybrid buses London's red buses are going green. Hybrid buses are quieter, cleaner and more fuel-efficient than standard diesel buses.

Hybrid buses reduce emissions of local pollutants and carbon dioxide by at least 30 per cent compared to conventional diesel buses. There are 172 diesel-electric hybrid buses in London. By the end of March 2012 the total number of hybrid buses in the fleet will be 269.

Hybrid buses are powered by a mix of an ordinary diesel engine and an electric motor. The hybrid buses we use also have regenerative braking, which means they generate electrical energy when the brakes are pressed. This electrical energy is stored in a battery pack and used to drive the electric motor.

London test their hybrid buses to make sure they produce feweer greenhouse gas emissions, harmful pollutants and lower noise levels.

Compared with diesel buses, hybrid buses deliver environmental benefits including:

  • Minimum 30% reduction in fuel use
  • Minimum 30% reduction in carbon dioxide
  • 3 decibel reduction in percieved sound levels
  • Reduced oxides of nitrogen and carbon monoxide

London - sustainable transport - Low Emission Zone

What is the LEZ?

The low emission zone (LEZ) was introduced in 2008 to encourage the most polluting heavy diesel vehichles driving in the capital to become cleaner. The LEZ covers most of Greater London. To drive within it without paying a daily charge these veichles must meet certain emissions standards that limit the amount of particulate matter (a type of pollution) coming from their exhausts

Despite significant improvements in recent years, London's air pollution is still a concern

So much so that on 3rd January 2012, the LEZ emissions standards became more stringent. More veichles are affected, and those that were already affected need to meet tighter emissions standards.

How does it work?

There are no barriers or tollbooths within the LEZ. Instead, cameras will read your number plate as you drive within the LEZ and check it against the database of registered vehicles.

This database is complied using information from the driver and vehicle licensing agency (DVLA), the vehicle operator services agency (VOSA), generic vehicle weight data typical of the make and model and drivers and operatore who are registered with them.

This tells them automatically whether your vehicle meets the LEZ emissions standards, is exempt, is registered for a discount or if you've already paid the daily charge

Where does it operate?

The LEZ covers most of Greater London.

All roads within Greater London, those at Heathrow and parts of teh M1 and M4 are included. However, ther M25 is not included (even where it passes within the Greater London Authority boundary.

There are signs to tell you where the boundary lies and which side of the road it applies to.

Problems picking up and returning cycles

If there are no cycles

  • When you get to a docking statio, the terminal map shows where there are some nearby.

If the docking station's full

  • When you return your cycle, check the terminal to see where there are free docking points nearby. You can get up to 15 minutes extra time from the terminal if you need to cycle to another station.

Problems parking

Parking a cycle

  • You can only leave your cycle at a docking station. Don't leave it unattended anywhere else. If you have it for more than 24 hours you'll get charged £150 for its late return.
  • Always return it to a docking point that's got no lights on and push it firmly into place. Wait until the lights turn green to ensure the cycle's put back properly or we won't know you've finished with teh cycle and will keep charging you. There's a five minute wait between returning a cycle and hiring another.

HINT: If all your journeys are under 30 minutes, all you pay is your access fee
