What It Is

Consequential-lca.org is an open resource site centered on consequential life cycle assessment (cLCA) modeling. Its goal is to show how to build consequential product system models following the approach recommended by the ISO 14040 series. It is not an online course platform in the traditional sense, but rather a combination of theory pages and a case library. It is aimed at students and early-stage LCA practitioners, filling in modeling details that are often compressed or omitted in scientific papers and LCA reports.

Core Content and Format

The site focuses on key modeling issues in cLCA, including functional units, marginal suppliers, determining products and dependent co-products, co-products/recycling/waste, and multiple determining products. Its case materials cover topics such as Brazil’s industrial fuel marginal mix and the co-production of zinc and heavy metals, emphasizing how to identify which activities are affected by changes in demand. The teaching format is mainly English text-and-image materials. Some topics mention YouTube videos, but there is no sign of a structured live course, recorded class series, 1-on-1 tutoring, assignments, or quizzes.

Pricing and Certificates

The site clearly offers free access, and its text and case materials are licensed under Creative Commons Attribution Share-Alike 4.0, making them suitable for teaching, citation, and reuse. No paid subscription, course package, payment method, or certification information was found in the main content. As a result, it is better understood as a learning resource library than as a training product that provides a completion certificate.

Pros and Cons

Its strengths are its high level of specialization, concrete case examples, free and open access, and maintenance by 2-0 LCA, a consultancy based in Aalborg, Denmark that focuses on consequential modeling and decision-oriented LCA. It is especially useful for understanding concepts such as “determining products/co-products,” “system expansion/substitution,” and “marginal supply.” The limitations are also clear: the content is relatively academic and technical, making it less friendly for learners without an LCA background or with weaker English reading ability; information on learning pathways, interactive Q&A, progress tracking, and support services is also limited.

Who It Is For and Access from China

It is suitable for students in areas such as environmental assessment, industrial ecology, and sustainable supply chains, as well as practitioners who are new to cLCA and need to look up modeling examples. Those looking for a complete Chinese-language course, a certificate, or hands-on software training may need to combine it with university courses, openLCA resources, ecoinvent training, or courses from professional organizations. Access to the website itself from mainland China cannot be confirmed from the available content; however, since some video links point to YouTube, related video learning may be restricted. Overall, access can be considered “partially restricted.”
