Green Public Procurement (GPP) is a process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life cycle when compared to goods, services and works with the same primary function that would otherwise be procured. GPP is a voluntary instrument, which means that Member States and public authorities can determine the extent to which they implement it. Public authorities are major consumers in Europe, spending approximately 2 trillion Euros annually, equivalent to approximately 19% of the EU’s gross domestic product. By using... their purchasing power to choose goods and services with lower impacts on the environment, they can make an important contribution to sustainable consumption and production. Since January 2010, the European Commission has published on its website a series of examples of the implementation of GPP throughout different Member States. These examples shall illustrate how European public authorities have successfully launched ‘green’ tenders, and provide guidance for others who wish to do the same. This brochure includes a collection of some of the most interesting examples collected over the years.
