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

The Carbon Hierarchy
Source: HEFCE January 2010/01 adapted from the DCSF Zero Carbon Task Force and Parkin
Carbon Hierarchy
Halve the demand, double the efficiency and halve
the carbon in the supplies and you are down to
one-eighth of the emissions

or do
you mean Cost Cutting?
In particular be wary of cost cutting on:
• Fenestration and rooflights: Especially
where rooflights are central to the
daylighting and/or ventilation strategy.

What does the future look like?
Aufkirchen ‘passivhaus’ School, Munich
Air tightness < 1 m3/hr per m2
Heating requirement < 15 KWh/m2a
Primary energy demand < 120 KWh/m2a

Re-Thinking………………….
"We cannot solve our
problems with the same
thinking we used when we
created them."
Albert Einstein
The Journey – Leadership from Government
The Journey – Leadership from industry
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.
