sustainable procurement
Sustainable Procurement…?

“Sustainable Procurement is a process whereby organisations meet their needs for goods, services, works and utilities in a way that achieves value for money on a whole life basis in terms of generating benefits to society and the economy, whilst minimising damage to the environment”.

Definition from the Sustainable Procurement Task Force

Procuring the Future – June 2006

Procurement journey

Benchmarking how well you are addressing your sustainability issues against how well others are addressing theirs

Halve the demand, double the efficiency and halve the carbon in the supplies and you are down to one-eighth of the emissions

Re-Thinking………………….

"We cannot solve our problems with the same thinking we used when we created them."

Albert Einstein

never waste a good crisis
Never Waste a Good Crisis

Develop a New Generation of Leaders

We must develop a new generation of leaders who can communicate their vision and drive change in culture and behaviour

Adopt New Business Models that Promote Change

Business models are fundamental to changing behaviour. We must move away from models that encourage short term thinking and find ways to incentivise long term value creation

Procure for Value

All customers in the chain need to professionalise their procurement to achieve best value, rather than focusing on lowest price.

Andrew Wolstenholme October 2009
