Decision support for local environmental impact assessment

Sustainability has become a key concern for consumers and industry. However, coming to understand its implications in the context of daily life can be difficult. It may be hard to come to terms with the idea that traditional activities present environmental risks and may lead to real emergencies, manifested differently depending on local conditions. Everyone will be asked to do more but the move towards sustainability may require the total transformation of current attitudes and actions. This paper considers the role of informatics in responding to, and possibly averting, environmental emergencies by making information available to decision makers, whether they are individual consumers, institutional buyers, or emergency response personnel. If all choices can be presented within a spectrum of best and worst possible impacts for sustainability, decision makers can meaningfully weigh their options. Any evaluation on this basis is presently very difficult because one needs to independently assess and integrate possibly incomplete and conflicting information from a wide variety of sources. This paper describes the use of the cogito software, which embodies an approach for data access and presentation that is expected to provide significant benefits over existing web-based tools. The paper also considers the issues related to the collection and synthesis of disparate data. 2006 Elsevier Ltd. All rights reserved.
