Dear Transport for London,

Please let me have a copy of carbon emission data associated with the whole life cycle of materials, energy use and construction of the following roads:
1. A13 Lodge Avenue Flyover Removal
2. Brent Cross Brent Cross Highway Structures
3. Fiveways Croydon
4. A232 The Croydon Flyover
5. Lombard Roundabout, A23 Croydon
6. Gallows Corner Roundabout Improvements
7. Waggoners and Henlys Roundabouts
8. A21/A205 Catford Town Centre
9. Hope and Anchor Flyover A316 Twickenham Rd / Great Chertsey Rd
10. Wandsworth Town Centre
11. Kew Bridge

This is sometimes referred to as “embodied carbon”.
For the avoidance of doubt this is not a request for carbon emissions data directly related to the use of the road by all kinds of vehicles over the 60 year assessment period.

Please let me know if these assessments of carbon were carried out following guidance contained in PAS2080 Carbon Management in Infrastructure and which organisation or consultancy /consultancies carried out the assessment.

If one part of the request can be answered sooner than others, please send that information first followed by any subsequent data. If you need further clarification, please contact me.

Thank you for your help.

Yours faithfully,

Kris Welch

Our ref: FOI-1906-2021/GH

 

Thank you for your request received by Transport for London (TfL) on 21
December 2020 asking for information about embodied carbon in road
building.

 

Please think carefully about whether the request is essential at this
current time, as answering FOI requests will require the use of limited
resources and the attention of staff who could be supporting other
essential activity. Where requests are made, please note that our response
time may be impacted by the current situation and so you may wish to

Dear Kris Welch

 

Our ref: FOI-1906-2021/GH

 

Thank you for your request received by Transport for London (TfL) on 21
December 2020 asking for information about embodied carbon in road
building.

 

Your request has been considered under the requirements of the
Environmental Information Regulations and our information access policy.

 

Unfortunately we do not hold the information you require. All the schemes
mentioned in your request are part of the DfT MRN (Major Route Network)
bids we are currently preparing business cases for. They are a mixture of
asset replacement/refurbishment schemes and transformational schemes.

 

All schemes are at very early stages of development we have had an
opportunity to undertake the carbon calculations yet.

 

There is a significant cost for these works and TfL is still developing
its approach to carbon modelling to ensure it adds value. There are trials
ongoing to meet the requirements of PAS2080 in the London Underground (LU)
and Major Projects Directorate (MPD) business areas. The outputs of this
will be reviewed and a decision will be taken whether to expand PAS2080
compliant modelling to other projects and business areas.

 

The following Major Projects & Asset Renewals’ projects are highway
structure maintenance and like for like capital renewal works. We haven’t
done and do not anticipate doing any carbon modelling for these types of
works:

 

Brent Cross Brent Cross Highway Structures

A232 The Croydon Flyover

Hope and Anchor Flyover

Kew Bridge

 

The works are of a high magnitude of cost (over £50m in some cases) due to
the scale of the assets and not necessarily the complexity. We are not
doing any new development work either or changing the existing highway
configurations. Therefore there isn’t a lot of potential for carbon
savings from alternative design solutions. TfL already ensures that high
levels of recycled materials are used in all road schemes to minimise
embodied carbon.

 

If you are considering submitting a further FOI request please think
carefully about whether the request is essential at this current time, as
answering FOI requests will require the use of limited resources and the
attention of staff who could be supporting other essential activity. Where
requests are made, please note that our response time may be impacted by
the current situation.

 

If you are not satisfied with this response please see the attached
information sheet for details of your right to appeal.

 

Yours sincerely
