Many initiatives have been undertaken in OECD countries, most successfully in Japan and Denmark where green public purchasing has been proven to be workable and highly effective, while, in other countries, city municipalities have successfully pioneered the development of sophisticated public environmental purchasing policies...The book, organised under the auspices of the International Council on Local Environmental Initiatives (ICLEI) analyses national approaches already tested, and provides in-depth surveys on the pioneer cities such as Hamburg, Malmö and Zürich...The most relevant product groups for eco-procurement such as construction, transport, energy, information technology, furniture and food. are also analysed.
