14. AMP5 Success Story
Over AMP5 we have had huge success in our Capital and
Operational Carbon Reduction
• Capital carbon reduced by 45% overall
from 2011-2015 from 2010 baseline
• In Y5 of AMP5 capital carbon has been
reduced by 54% from 2010 baseline
• Operational carbon has exceeded a
10% in real terms since 2010.

30,000 population growth
• Proposal cost £24m
• Affordability £17m
• Sustainable Solution £14m
• Embodied Carbon - 66%
• Operational carbon -170%

16. Precast concrete
Precast concrete units provide a more cost
effective solution than plastic for certain
ground conditions.
28% cost saving
35% reduction in capital carbon
(increased reduction with further cement
replacement)
Conventional in-situ reinforced concrete
Conventional techniques are labour and materials intensive.
Structured plastic in curved trench
A specially fabricated bucket
enables a curved-bottom trench to
be dug, making significant savings
on imported bedding and
surround materials.
38% cost saving
37% reduction in capital carbon
2010 : Innovation in our supply chain
What’s Next ?

17. 2015 + Success Stories –
Low carbon Concrete
• According to ‘The
Independent’ cement
manufacture accounts
for 5% of global
emissions.
• AWS the first utility to
use cemfree – cement
free concrete
• 60-70% capital carbon
reduction in the
concrete base.

Who has developed PAS 2080

21. • Must be undertaken
collaboratively by all parties across the value chain
• Compliance can be:
– monitored and self-validated by the applying entity; or
– assessed and validated by independent bodies
A carbon management process
for use in infrastructure delivery
Objective: reduce carbon from
infrastructure to reduce cost.
What is the aim of PAS
2080

22. Who should use PAS 2080?
All value chain members involved in
infrastructure delivery

What is the Structure of
PAS 2080

24. • Requirements for all value chain members
• Asset owner/manager requirements
• Designer requirements
• Constructor requirements
• Product/material supplier requirements

PAS 2080

25. The Carbon
Management Process

26. The Carbon Management
Process
Leadership and good governance are key
enablers, provide vision, motivate right
behaviours and are essential right across
value chain

27. The Carbon Management
Process
Carbon reduction targets provide clear
direction and communicate intent

28. Clear baselines enable performance against
targets to be determined
The Carbon Management
Process

29. The Carbon Management
Process
Monitoring at frequent intervals shows
progress against agreed targets

30. The Carbon Management
Process
Quantification identifies carbon hotspots, gives
confidence, informs carbon reduction strategies
and allows results to be transparently compared

31. The Carbon Management
Process
Reporting makes performance visible and informs
decision-making in managing whole life carbon

32. The Carbon Management
Process
Continual improvement informs future work and
helps organisations to grow in carbon maturity

33. PAS 2080 is supported by
Guidance Document
Provides practical advice
on how to:
• implement PAS
requirements
• address current good
practice through
worked example and
case studies.
Available by downloading from:
www.greenconstructionboard.org

34. PAS 2080 is supported by
Guidance Document
Presented in an engaging style suitable for reading
on-line or in hard copy, with clear cross-references
to PAS clauses.
