Tube Lines


Tube Lines recognises that effective management of the environment is an essential and integral part of business management. We have held ISO 14001 Environmental Management Systems accreditation for four years and in 2009 were awarded a ‘Platinum’ level badge for our environmental, energy and carbon management work – as part of the Mayor of London’s Green500 scheme.

Carbon footprint

We calculated our overall carbon footprint in 2006 and have been reducing year-on-year our impact on the environment by improving the way we do things, calculating the carbon reductions and calculating the carbon savings associated with those new and improved activities.

Since 2007, Tube Lines has been actively working to reduce its carbon footprint. In 2012/2013, we plan to reduce this figure by a further 1,200 tonnes.

We have:

  • Reduced the amount of energy and utility consumption in our buildings.
  • Improved how we use materials.
  • Reduced the amount of waste that we produce.
  • Reduced the number of transport miles we travel.
  • Improved our vehicle fleet to lower emission vehicles.
  • Reduced the annual mileage our vehicle fleet does by becoming more efficient.

Climate change

We have quantified the effect that a changing climate will have in the decades to come on our railway assets. Over 200 possible threats and opportunities have been identified.

We have identified how climate change in London will affect our work, including:

  • Extreme heat and cold.
  • Reduced summer rainfall and wetter, milder winters.
  • More intense rainfall events.
  • Changes to season length.

We’re already adapting to a changing climate and have installed one of the largest green roofs on a railway building, and are benefiting from an innovative rainwater harvesting system. The rainwater feeds into an automatic train washing machine and has reduced demand for mains water by up to 80%.

We continue to calculate how the climate will impact on our business and we are mitigating and adapting for future uncertainty.

Environmental Policy objectives

These are as follows:

  • Ensure compliance with UK and European legislation and requirements.
  • Implement and maintain our ISO 14001 certified environmental management system (Go Green).
  • Prevent noise and nuisance from our activities using best practicable means.
  • Prevent pollution incidents and reduce emissions.
  • Promote sustainable use of resources and reduce disposal of waste to landfill.
  • Conserve and safeguard flora, fauna and heritage.
  • Calculate and reduce our carbon footprint and respond to climate change.
  • Work in partnership with London Underground to achieve mutual environmental goals.

Waste and Recycling

Tube Lines is a proud supporter of the government’s Waste and Resources Action Program (WRAP) ‘Halving Waste to Landfill’ initiative. We currently recycle in excess of 90% of all of our non-hazardous waste streams from all of our business areas.

In the morning rush hour, it can be a challenge to spot a passenger without a newspaper and many papers get left behind. We collect those papers which are left on trains and in stations for recycling.


We are determined to increase the use of sustainable materials in our projects. In 2006, we installed London’s largest single membrane green roof – the first on a railway building – on the new £14m Northern line control centre which will house state-of-the-art signalling equipment.

The green roof has bedded in so well that we also installed one on our new Stratford train crew accomodation at Trackside House.  Trackside House also has other innovative environmental features.  For example it is clad in copper and renewable Siberian larch wood, and sheep’s wool is used for insulation.

We regularly work with conservation partners the Woodland Trust and London Wildlife Trust to fulfil our promise to replant two trees for every tree we have to fell as part of our maintenance and improvements works. Unfortunately, we can’t normally replant trees back in the place we have felled them for operational reasons. Our conservation partners plant trees as close to where they are felled as practical. However as space is limited in London, they are often planted in a local nature reserve up to a few miles away.


We are very proud to be at the cutting edge of railway environment managment and sustainability. This has been recognised with several National Awards:
