Our commitment to the environment

Providing the most sustainable intercity network in the UK

How we're playing our part...

We take our environmental responsibilities very seriously, and we recognise that we have an important part to play in reducing emissions and combating climate change.

This is why it’s our vision to be the UK’s most sustainable coach company.

We continuously invest in the cleanest most efficient coaches available, but we want to do more. So we’ve committed to making our coach fleet zero emission by 2035 - ahead of the UK net zero target of 2050.

Don't just take our word for it, take a look at the figures below on the performance of our vehicles, which show we already have the greenest coaches on the road…

Our fleet

Our core white coach fleet is Euro VI standard - the highest engine emission standard available. The Levante III Euro VI coach specification is bespoke and exclusive to National Express. We tested its emissions performance in early 2020:

  • Our Levante III produces an average of 21.7 grams of greenhouse gas emission (GHG) per
    passenger kilometre at 100% passenger capacity.
  • In an urban environment, our Levante III produces 13.6% less GHG emissions per passenger
    kilometre than other types of Euro VI coaches on the road today.

Here’s how a full National Express coach benefits the environment
