The Aarhus Convention (1998) established that sustainable development can be achieved only through the involvement of all stakeholders. It linked government accountability with environmental protection and focused on interactions between the public and public authorities in a democratic context. This has led to a clear need for public participation and consultation during the environmental permitting procedures.There is therefore a great need for a system that integrates relevant processes and services collected by public authorities and agencies, to enable them to model and deploy services, as a cloud of e-Government services that support environmental licensing procedures to citizens and businesses. For this purpose, basic operational services will be aggregated on the platform and will be offered to citizens as e-services. At the same time, the architecture of the platform will give the public administrations the opportunity to deploy easily new services, and existing procedures will be available as shared services. Geographical information services are critical for this system, since the decision making process of all stakeholders is dominated by information that has a clear spatial dimension.The eEnviPer project aims to test an existing single multi-purpose cloud platform based on Service Oriented Architecture (SOA) for providing software as a service in five different European countries. The project will demonstrate the benefits of SOA and cloud architecture by integrating complementary existing systems that support environment-related permit procedures and provide digital services for permitting authorities at different levels, enterprises, consulting services and civil society (either individual citizens or special interest groups such as NGOs).
