Eco-efficient purchasing means maximising the value added (read: usefulness, pleasure, user satisfaction, satisfaction of needs, contribution to efficient operations), while minimising the environmental impact (read: consumption of raw materials and energy, pollution, waste generation) of the product or service.

Eco-efficient purchasing is not a substitute for - but a supplement to - the concept of efficient purchasing.

GRIP makes its contribution in the field of eco-efficient purchasing by equipping professional buyers, both private and public, with the necessary knowledge and tools to implement the concept in a hectic everyday situation.
