2. Carbon V Cost

4. Targets
Exceed a 7% reduction in real terms in gross operational carbon by 2020 from a baseline
Deliver a 60% reduction in capital (embodied) carbon by 2020 from a 2010 baseline

7. Success Story
Through we have had huge success in our Capital and Operational Carbon Reduction.
Capital carbon reduced by 45% overall from from 2010 baseline
In 2015 capital carbon has been reduced by 54% from 2010 baseline
Operational carbon has exceeded target.

8. Build off-site trickling filter
Success Story
Product Based Delivery has led to some significant reductions in capital carbon through standard products, new innovative solutions and off-site construction methods
New thinking involving…
Standard Products
Engaging with supply chain
Exploring new materials and techniques
Off site construction
Innovative solutions
Reducing waste
From To
~40% Reduction
Build off-site trickling filter

9. 2010 : Innovation in our supply chain
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
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)

What’s Next ?
Cement free/low carbon concrete.

10. 2015 + Success Stories – Cemfree 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.
