Started as a Graduate Trainee in September 1996 Environmentalist by trade Executive Committee member Responsible for sustainability, safety, environment, carbon management, marketing and communications Active in various networks such as the UK Green Building Council, CBI, Institute of Quarrying And who am I?
Resources we used in 2010 Bitumen 267,720 tonnes Cement 755,764 tonnes Pulverised Fuel Ash (PFA) 129,627 tonnes GGBS (Slag) 69,252 tonnes Packaging 10,742 tonnes Water (mains and abstracted) 5,093,012 m 3 Gas 237,533 MWh Electricity 165,465 MWh Oil all grades 686,470 MWh What we use in our products and services
Outputs from our business in 2010 Aggregates 30.2 million tonnes Secondary (processed) 1.13 million tonnes Asphalt 5.45 million tonnes Ready-mixed concrete 2.18 million m 3 Precast concrete products 2.27 million tonnes Waste 147,170 tonnes (43,127tonnes to landfill) Transport emissions 4.87 kgco 2 /t Process emissions 5.93 kgco 2 /t What we produced
There is simply not enough resources to go around given your average Western lifestyle For most people, more is more Life is not like a cheesy American movie mass societal change is not inevitable So we have to find ways of giving people what they think is more but actually give them less The world really is in a tight spot across a whole range of resources
It s not uncommon for 50% of a country s environmental impacts to come from the operation of buildings A major component of this is typically carbon dioxide emissions Zero carbon homes are due 2016 but what about the 20 odd million that are already built We remain in a place where there is no commitment to display the actual energy consumption of commercial buildings There are specific issues with the built environment
Buildings UK CO 2 emissions by end use
Solutions that are transferable from domestic to commercial, from new build to retrofit are required
Similar technology can be used for roads

Materials used need to work harder for us
A much more complicated issue is water. Too much, too little, not the right quality.
To make substantial in-roads into our collective problems, we really need scale
Over 90% of the total aggregate volume delivered to the Olympic Park by rail 95% of the raw materials for concrete production imported to the site by rail Average cement substitutions of 32%, supporting the ODA in saving over 85,000 tonnes of embodied carbon Concrete with a secondary aggregate content of more than 50% supplied to several venues, including the Olympic Stadium and Aquatics Centre. Many of the fair faced concrete structures incorporate 30% secondary content Scale, ambition and confidence to try something new
And without those attributes at a commercial level, moving forward is going to be very challenging indeed
