About the methodology

In France, the building sector is responsible for 23% of greenhouse gas (GHG) emissions, with a significant portion arising from the embodied phase—the materials and energy used in constructing and maintaining buildings. For residential buildings with a 50-60 year lifespan, embodied emissions can represent 15–40% of total life-cycle emissions.

The most effective strategies for reducing embodied emissions include extending the lifespan of existing buildings and materials and increasing building use intensity. These circular renovation actions reduce the demand for new construction, which requires more resources than renovating existing structures.

Construction Materials Reuse

No documentation found.

Technology

Projects eligible under this methodology are the activities that refurbish or reuse construction materials, in substitution of new construction materials.

Covers any kind of construction materials backed by an EPD or a FDES document (in France notably)
Eligible Projects Developers are either: material manufacturers or building developers reusing construction materials.
All projects are eligible for avoidance Riverse Carbon Credits (RCCs).

Scientific approach

Quantification

Project and baseline scenario for the reuse of construction materials methodology note.

Open image

The methodology quantifies carbon removals and GHG emissions avoided compared to baseline scenarios using the ISO 14064-2 standard. In this methodology, all projects must submit detailed life cycle assessments (LCAs) to quantify emissions accurately.

Project scenario:

Since the products reuse are from deconstruction sites and are considered as waste, the impacts from their first life is not taken into account.
Therefore, there is no production stage of the first life of the product.
The life cycle starts with transportation to the new construction site, the reconditioning site, or the warehouse
When reconditioning is necessary, the impacts from the reconditioning processes is included.

Baseline scenario:

Includes the waste treatment of the product from its first life cycle;
the production of a new product;
the transport of this product from its manufacturing site to the construction site.

Core criteria of the methodology

Compliance

Greenhouse Gas (GHG) Emissions Calculation

We adhere to the ISO14064-2 standard to accurately quantify GHG emissions reductions and sequestration. Our approach ensures that all calculations are transparent, consistent, and reliable.

Our approach

Project Reporting

All our projects must comply with the General Standard Rules in accordance with ICVCM and ICROA requirements. This ensures the highest level of integrity and transparency in our reporting processes.

ICROA accreditation

Audit and Verification

Every project undergoes rigorous validation and recurring verification/monitoring audits by accredited Validation and Verification Bodies (VVBs). This process guarantees the credibility and accuracy of our projects' emissions reductions.

Construction Materials Reuse

In 2017, total waste production in France was 326 million tonnes of which 224 came from the construction sector (68.7 %). Recovering this waste would help to significantly reduce GHG emissions and the use of new materials.

Low Carbon Cement

Low carbon materials in the cement industry represent innovative alternatives designed to minimize the environmental impact of traditional cement production, which is known to be a significant contributor to the building sector’s emissions.

Battery Refurbishing and Regeneration

The reuse of batteries achieving the end of their first life can reduce the battery impact. Secondary life batteries have lower embodied GHG emissions than new ones. A method for achieving this is the refurbishing and regeneration of used batteries, which involves restoring previously owned and used batteries to a functional state.
