The Footprint of Things: A hybrid approach towards the collection, storage and distribution of life cycle inventory data.
ICT4S(2018)
摘要
Life cycle assessment is a well-established methodology for assessing environmental impacts of products and services. Unfortunately, an essential part of this life cycle assessment method, col- lecting inventory data, is extremely time consuming. The quality of manually conducted LCA studies is often limited by uncertainty in inventory data or narrow scope. Past attempts to overcome these challenges through automation of data collection utilizing Internet of Things have relied on fully centralized architectures. The drawback of a central repository is complex coordination between all involved actors in supply chains of products and services. This paper proposes an alternative hybrid approach combining a primary distributed system supplemented with a central repository reducing need for coordination. This hybrid approach is named the Footprint of Things. We present a system design that embeds automatic reporting of life cycle inventory data, such as energy and material flows, into all product components involved in a service delivery. The major strength of our novel system design, among others, is its capacity for real-time and more precise impact calculation of ICT services.
