Susta.Info will enable local authorities and experts to attain sustainable development, by establishing a portal and web based database of which the usefulness and continuity is ensured. Practitioners in Europe and beyond will have unconstrained access to information on sustainable development from the UN Habitat Best Practices and the EU?s City of Tomorrow and 6FP land management projects. Projects will be abstracted and validated, so that they can be searched and accessed in a standard and comparable way. State-of-the-art information retrieval technology guarantees both good search results and access for all types of computer users. Dissemination activities will make Susta.Info known to at least 6,000 target users. Susta.info is a well-organised project in volving information suppliers and users in the development of the system. The project will stimulate international co-operation among the UN and European Commission on the one hand and among local practitioners on the other. The work is organised into four work packages concentrating on Content, System Development, Dissemination and Co-ordination.
