The amount of waste we produce is linked directly to the number of construction sites that we have. The more work we do, the more waste we produce. We are a growing business, and so our target – of reducing construction waste by 15% by 2015 compared with 2012, is expressed in terms of intensity – that is – the amount of waste we produce in relation to project value. 
It is important to note that our target relates simply to construction waste, because we have limited control over waste which comes from demolishing existing buildings or excavating sites. This waste may be classified as hazardous, and therefore not suitable for recycling. However we aim to re-use waste from both demolition and excavation activities wherever we can.
Our longer-term ambition is to achieve zero waste to landfill by 2020.
