What are the CRREM Pathways?

expand_more
The CRREM Pathways are science-based decarbonization pathways for the real estate sector. They translate global carbon budgets derived from IPCC scenarios into property-level emissions and energy intensity targets — covering more than 1,000 pathways across 44 countries and all major property types.

What is the CRREM Misalignment Year?

expand_more
The CRREM Misalignment Year is the projected year when a building's carbon emissions or energy use intensity will exceed its science-based CRREM Pathway. It signals the point at which a building becomes misaligned with Paris Agreement targets — a property-level transition risk indicator.

Is the CRREM data free to use?

expand_more
Yes. The CRREM Pathways, emission factor projections, and all underlying datasets are published open-access on crrem.org. Anyone can download and use them. Software platforms that embed CRREM data commercially require a License Partner agreement.

Why did CRREM rename "Stranding Year"?

expand_more
In July 2025, CRREM replaced "Stranding Year" with "CRREM Misalignment Year" to better reflect what the tool measures: misalignment with climate targets, not a definitive loss of asset value. The underlying methodology is unchanged.

How are the pathways developed and updated?

expand_more
All changes follow a formal governance procedure with three tiers: low-impact maintenance (Secretariat), medium-impact development (Technical Council), and high-impact revision (Technical Council plus Foundation Board). All significant changes undergo stakeholder consultation before adoption.

What is the EUI Methodology Review?

expand_more
The EUI Methodology Review is the first formal review of CRREM's global energy pathways since their initial publication. Led by the Technical Council, it includes a structured market sounding with townhalls and deep-dive sessions. Enhanced guidance is expected later in 2026, subject to public consultation.

Who oversees the CRREM Pathways?

expand_more
The CRREM Technical Council — 13 independent experts from academia, research institutions, and industry — is responsible for the scientific quality and technical oversight of the pathways. The Foundation Board provides strategic oversight and final adoption of high-impact changes.

What happened to the CRREM Risk Assessment Tool?

expand_more
The CRREM Risk Assessment Tool — the free Excel-based calculation tool — will be retired on 1 July 2026. The ecosystem of more than 40 License Partners now delivers the methodology through integrated platforms. All pathway data and computation guidance will continue to be published open-access.
