Using Blockchain Technologies and Automized Digitalization for Data Collection in the Upstream Supply Chain

Dear Colleagues,

Sustainability management involves huge amounts of data. At the same time, if we cannot measure something we cannot control it. As pinpointed by numerous authors – actually in almost every Life Cycle Assessment (LCA) case study published so far - the main challenge for the overall credibility of LCA results is the collection of primary data of high quality.

However, soon the time will come wherein we are able to measure supply chains in real time - as accurately as use stage power consumption which is measured by e.g. smart metering - and then, can LCAs of products finally be validated?

So far, I have not seen a deeper discussion about real-time data collection in the LCA community.

A couple of years ago I had the notion that artificial intelligence (pattern recognition, neural networks, scheduling, reasoning, fuzzy logic, rule-based systems, machine learning) would help revolutionize the Life Cycle Inventory (LCI) data collection in the supply chain [1].

However, I had not thought about the potential role of blockchain technology in removing costs, security issues and inefficiencies in LCI data collection. Blockchain is potentially suitable for LCI data collection as these data should be distributed and shared by many users in a secure manner. As the security of distributed ledger technologies is extraordinary high, these technologies are strong candidates for distribution of more or less sensitive manufacturing LCI data.

I welcome submissions presenting practical solutions for supply chain transparency using blockchain systems – and other competitive solutions - for life cycle inventory data collection. Examples could also include theoretical schemes for blockchain systems for LCI data recordkeeping and distribution.  Already existing data collection solutions – using blockchain - could here be presented in a scientific manner, i.e. how they go beyond of the static state-of-the-art LCI data collection practices. Other progressive solutions for LCI data collection - based on e.g. cloud servers - which move things forward compared to the state-of-the-art, are also interesting for this special issue.

An idea is that the manufacturers anonymously report LCI data (e.g. emissions and energy use) manually - or automatically via sensors installed in the factories - to a distributed ledger. In this context, the well-established LCI data provider Ecoinvent in Switzerland is responsible for developing validation, sanity checks and intelligent “polishing” functions within the ledger.  Then each organisation - subscribing to Ecoinvent - will have access to the LCI data they desire in real time. If materialized, this would be a huge improvement of the current practice of LCI data collection and data relevance.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Challenges is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
