ABSTRACT
Rapid development of information technology has changed people's attitudes towards information usage. To tender to the public's expectation, information system must feature facilities to increase the efficiency of information usage using modern information technology. Facing this challenge, it is necessary to establish a sustainable information environment, including information policy, data quality regulations and information management framework to deal with the rapidly increasing environmental data and changing behavior related to data/information usage except upgrading the hardware and software devices. Taking the uniqueness and complexity of environmental data into account, this study proposes a systematic framework based on the principle of life cycle assessment to outline the elements and its associated guidance required for a sustainable information environment. Simultaneously, the concept of information ecology is also embedded into such a planning for the purpose of establishing a self-evolutional information environment. Finally, the environmental protection administration of Taiwan is used as a case study to explain the practice of proposed framework
