Circular Economy
Circular Economy is based on three principles: design out waste and pollution, keep products and materials in use through refurbishment, reuse and design for adaptation or deconstruction, and regenerate natural systems. The concept of retaining materials at their highest value normally means that embodied carbon invested is also retained and low carbon outcomes are more likely. However, this is not always the case, and it is important to design for outcomes that are both low carbon and circular.

Some examples are extraction and production of purchased materials, transportation of purchased fuels, use of sold products and services, and flying on a commercial airline by a person from another business. Also referred to as supply chain emissions.

Comments and suggestions

MECLA, the Materials and Embodied Carbon Leaders’ Alliance, is a collaboration of organisations that have come together to drive reductions in embodied carbon in the building and construction industry. MECLA members seek to align with the Paris Agreement targets and principles of the circular economy and recognise that the building and construction sector is a complex ecosystem. These definitions were developed by volunteers from MECLA Working Group 4 and have been reviewed by volunteers from all other MECLA working groups.

Whilst many hours of care and attention have been gone into the development of this dictionary, it’s possible some terms have been omitted, or you may have a suggestion for an alternative definition. Please help us improve this free industry resource if this is the case.

We welcome all suggestions for improvement using the form below.
