Using Less Stuff is about reducing consumption within your organisation. It can be hugely beneficial, through reducing costs and by promoting team cohesion by working towards a common goal.
The problem in most organisations is that there is a lone wolf howling in the dark about sustainability but nobody else is taking any notice. However, with both energy prices and energy usage continuing to rise and the demand for resources increasing, no organisation can afford not to look at how they can use less stuff!
The principle of Using Less is about educating for social responsibility. We want everyone to make conscious decisions about how they use resources – not so much whether we recycle (although this is still good) but to question if we really need to use the stuff in the first place?
