Construction Stored Carbon Certification Protocol

The Construction Stored Carbon Certification Protocol provides a structured framework for certifying the Net Carbon Removal Benefit (NCRB) of biobased construction projects. Developed by the Climate Cleanup Foundation, it aligns with the EU Carbon Removal Certification Framework and supports monetisation of carbon storage within the built environment. The protocol outlines eligibility criteria, measurement, reporting, and verification (MRV) processes to ensure robust and transparent certification.

Key Takeaways

1. Eligibility Criteria: Projects must use sustainably sourced biobased materials with a first-use lifespan of at least 35 years and meet additionality and sustainability benchmarks.
2. Certification Stages: The process includes phases such as ‘in design’, ‘under construction’, and ‘as built’, each requiring documentation, validation, and verification.
3. Quantification Framework: Standardised methods are provided for calculating NCRB using life cycle assessment (LCA) data and environmental product declarations (EPDs).

How It Can Help You
This protocol is a vital resource for developers, project operators, and policymakers aiming to certify carbon storage benefits in biobased construction. It helps align projects with sustainability objectives and carbon removal monetisation frameworks, while offering transparent methodologies to attract climate finance. By applying this protocol, stakeholders can demonstrate measurable climate impact and strengthen market credibility.

Key Learnings

1. Carbon Quantification: The protocol ensures accurate calculation of carbon removed and stored using standardised formulas and publicly available tools.
2. Sustainability Integration: Certification promotes long-term storage of biogenic carbon while supporting biodiversity and circular economy principles.
