100 commitments
and measures

5. Halve our
embodied carbon
in new assets we
build by 2015
from a 2010
baseline
Reduce our
operational
carbon emissions
by 10% in real
terms by 2015

Orthophosphoric acid dosing
The Mark II product provides a reduced footprint dosing
plant. Savings are made by buying in bulk (enabled by
programme visibility) and by reducing the amount of
design, installation and commissioning.
Saving of 23% on the cost of the product core
Saving of ~10% on embodied carbon
AMP 5 Standard Products :
Focus on Carbon & Cost
Air valves
Smaller and lighter than traditional AVs and more
efficient.
Saving of 36% on the cost of the product core
Saving of 93% on embodied carbon
Valve chambers
A telescopic sheath for the valve spindle eliminates the
need for a traditional chamber and reduces installation
time.
Saving of 50% on the cost of the product core
Saving of 27% on embodied carbon
P removal
1 tank instead of 2 and reduced footprint.
Saving of greater than 15% on product core
Targeting 50% reduction in embodied carbon
High efficiency aeration
Approximately 30% less air is needed with this
product, resulting in corresponding lower energy
requirements for the blowers.
Savings of 86% on Whole Life Cost
Savings of 25% on Whole Life Carbon
Polydosing
Cost saving of 15% on product core
Saving of 12% on embodied carbon

12. Precast concrete
Precast concrete units provide a more cost
effective solution than plastic for certain
ground conditions.
28% cost saving
19% reduction in embodied carbon
(50% reduction with cement replacement)
Structured plastic with conventional
bedding
Lower cost solution with lower embodied
carbon, but still requires bedding and surround
to be craned into position.
34% cost saving
39% reduction in embodied carbon
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
50% reduction in embodied carbon
(55% reduction with SMR)

19. What happened :
REDUCED CARBON REDUCED
COST
• Design engineers rose to the challenge
– Released from focus on cost and standard design
• Key Framework Partners & suppliers energised to deliver low carbon
solutions
• Strong link between lower embodied carbon and lower CAPEX
• Design engineers and suppliers challenged AWS to improve measurement
& management
– Strong illustration that reducing carbon matters to them !
