CRREM is an assessment tool for evaluating operational carbon emissions and carbon risks in real estate assets. It compares building energy and carbon performance with science-based decarbonisation pathways for commercial and residential properties. In EXEL4Housing 4.0, it is relevant for supporting housing stakeholders in understanding the carbon footprint of buildings during the operation and use phase, identifying assets at risk, and guiding retrofit actions towards low-carbon and climate-aligned housing.

Objectives
CRREM is used to assess the operational carbon footprint and carbon risk of real estate assets. Its purpose is to compare building energy and emissions performance against science-based decarbonisation pathways, identify when assets may become at risk, and support retrofit planning, target setting and climate-aligned decisions during the operation and use phase
Target audience
Real estate investors, asset owners, asset managers, housing providers and sustainability consultants working on operational carbon risk, decarbonisation targets and retrofit planning.
Benefits
CRREM helps users calculate and assess the operational carbon intensity of buildings, compare performance with science-based decarbonisation pathways, identify carbon or transition risks, and support retrofit planning to reduce emissions during the operation and use phase.
Data requirements
CRREM requires basic asset information such as building location, property type and floor area, together with operational energy consumption data by energy source. Users may also need annual GHG emissions, carbon intensity, reporting year, expected energy/carbon reduction, and planned retrofit actions to compare the building with CRREM decarbonisation pathways.
