2010-2015 Carbon V Cost

Targets Exceed a 7% reduction in real terms in gross operational carbon by 2020 from a 2015 baseline Deliver a 60% reduction in capital (embodied) carbon by 2020 from a 2010 baseline Outcomes

Taking the First Steps…. Regulator PR09 Instigated Action Back to back with cost models Followed SAP hierarchy Baseline to measure performance against Modelling Carbon Proving the Concept

Managing Carbon

2010-2015 Success Story Through 2010 - 2015 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 2015 capital carbon has been reduced by 54% from 2010 baseline Operational carbon has exceeded target.

Build off-site trickling filter 2010-2015 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

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) Speak to slide What’s Next ? Cement free/low carbon concrete.

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.
