This chapter introduces a Virtual Enterprise architecture for environmental information management, integration and dissemination. On a daily basis, our knowledge related to ecological phenomena, the degradation of the natural environment and the sustainability of human activity impacts, is growing. As a consequence raises the need for effective environmental knowledge exchange and reuse. In this work, a solution among collaborating peers forming a Virtual Enterprise is investigated. Following an analysis of the main stakeholders, a service-oriented architecture is proposed. Technical implementation options, using web-services or software agents, are considered and issues related to environmental information management, ownership and standardization are discussed.
