Overview

Life Cycle Assessment (LCA) and Digital Product Passport (DPP)
We develop and review the methods, data and information structures behind Life Cycle Assessment and Digital Product Passports.

As to LCA, we have a special focus on the European Commission’s Environmental Footprint (PEF/OEF) method, that we have originally authored 2010-2012, while working at European Commission. We work with and on other methods as well, e.g. the GHG protocol. Since 2013, we have continued in-person experience with PEFCR development, EF data and PEF studies review, advising industry and governmental bodies on method, data quality and data format further development, EF-compliant LCI dataset and database development.

Our DPP work covers information requirements, schemas and ontologies development and implementation, user interface and user experience, e-commerce, and market surveillance questions. maki is CIRPASS-2 consortium member and was contractor in the development and testing of the DPP scoping methodology for the European Commission’s Joint Research Centre (JRC), published in March 2026.

Our two senior experts bring more than 50 years of combined experience, advising and having worked at European Commission bodies, Thai public research bodies, Universities, and other consultants. We work at the interface between industry and policy.

Clients work directly with the senior expert responsible for the technical work.

Expertise, development, and review:

  • LCI dataset and database development, software specification and development support
  • DPP schemas and ontologies development
  • Strategic and policy advice
  • Independent review and verification of methods, data and studies

Circular Economy Formula (CEF) – a new, inherently closed-loop, attributional substitution approach for LCA, 2023

A new way of modelling of secondary products (materials, energy, parts, …) as input to and output from product systems has been developed by us: the Circular Economy Formula (CEF). The basic idea of this approach is that everything that is kept in the loop, i.e. handed back to the economy during End of Life …
