Carbon

Protecting and enhancing the local environment, and reducing our carbon emissions, is at the heart of everything we do

The project’s greenhouse gas emissions will come from three sources:

  • Construction – we’re a Pathfinder scheme that will explore carbon neutral construction
  • Operations and maintenance – we’ll be zero carbon in operations from 2030, and zero carbon maintenance by 2040
  • Road users – when the Lower Thames Crossing opens you won’t be able to buy a new petrol or diesel car or van, and the UK will be net zero by 2050

Carbon neutral construction

The Lower Thames Crossing is a Pathfinder project, meaning it will explore ways to be carbon neutral in construction. 

We’ve already been able to reduce our carbon emissions during construction by around a third, and are working with partners and suppliers to drive it out further.

  • We’re the first major infrastructure project to use our procurement process to target carbon
  • We’ll test and scale-up innovative and low carbon materials and technology
  • We’ll only use zero carbon electricity sources
  • We’re aiming to remove diesel from our sites and only use hydrogen and electric plant
  • We’ll reduce and beneficially reuse our waste

Road user carbon emissions

When the Lower Thames Crossing opens for traffic, you won’t be able to buy a new petrol or diesel car or van and within ten years the vast majority of cars are expected to be electric plug-in vehicles.

All UK roads, including the Lower Thames Crossing, are included in the UK’s commitment to reach net zero carbon by 2050.

Operations and maintenance carbon emissions

We will be zero carbon in operations from 2030, and zero carbon maintenance by 2040.

We’re committed to using renewable electricity for operations, 100% electric vehicles for non-traffic officer vehicles by 2027 and for traffic officers vehicles by 2030.

We’ve also committed to achieve zero carbon maintenance from 2040. The replacement of pavement the road surface is a key component part of our maintenance emissions and we’re looking at innovative low carbon asphalts.
