Plastic Pipes Conference Association # 2004 Milan


The Natural Step is an international NGO dedicated to Sustainable Development. The work we do is based upon a scientific approach and began with scientists and businesses in Sweden over ten years ago. Our framework uses science and systems thinking to help others get to grips with the complexities of sustainability.

We now have offices in US, Australia, Japan, New Zealand, Canada, South Africa, Israel, Sweden , UK and Brazil. There is interest in expanding TNS to new countries in almost every global region.
We are at a stage of our development when our potential to influence global affairs is coming to the fore.
