myEcoCost is a foundational methodology that defines a global collaborative network of resource accounting nodes. It provides a means of accounting for and expressing usage of natural resources for products, services and technologies, to inform all economic actors including SMEs (Small and Medium size Enterprise) and consumers, on environmentally relevant information. It is a novel, bottom up approach to measure resource efficiency, the results of which are applicable in corporate, industry and society wide contexts. It is an asynchronous, recursive, non-centralised data gathering and dissemination technique for a large scale stakeholder network.myEcoCost aims to support various environmental accounting and assessment practices applicable to various national and international environment policy objectives. It links business added value to a measurement of aggregated resource usage as accepted environmental pressure indicator which goes beyond single issue indicators such as carbon footprint. Using an Internet-based service-oriented architecture (SOA) relevant and timely data is passed from supplier to customer recursively through the whole value chain to produce “ecoCosts” for each product or service. The project will demonstrate how it is technically possible to provide timely and accurate resource efficiency statements.For this to happen a series of ICT (Information and Communication Technology) infrastructure components will be arranged: A resource accounting framework to determine “ecoCosts”, an ICT delivery mechanism to transfer the measurement from supplier to customer, benchmark figures for companies and consumers linking to macro level policy objectives, and interfaces for industry and consumers to interpret the measurement to assist decision making.The project aims at researching and developing all key ICT and software elements to trial and to demonstrate the resource accounting framework and infrastructure in a proof-of-concept prototype, involving various value chain actors, users, environmental data processors and policy makers.
