The real estate industry stands at a pivotal crossroads in the global pursuit of a net-zero economy. With buildings accounting for nearly 40% of global energy-related CO₂ emissions, the sector is under intense scrutiny from regulators, investors, and consumers alike. As climate policies tighten and sustainable finance grows in influence, real estate portfolios risk becoming "stranded assets"—properties that no longer meet market, regulatory, or environmental expectations. To navigate this complex transition, the Carbon Risk Real Estate Monitor (CRREM) has emerged as a vital solution. CRREM offers a science-based, transparent, and data-driven framework that enables stakeholders to align property investments with the decarbonization goals set out in the Paris Agreement, particularly the 1.5°C and 2°C global warming scenarios. By providing clear decarbonization pathways and stranded asset risk assessments, CRREM allows real estate professionals to make informed decisions that reduce emissions while protecting long-term asset value.
Prior to CRREM, the real estate sector lacked a consistent, science-based methodology to evaluate the carbon risk exposure of individual properties or entire portfolios. This gap was especially critical given the sector’s significant environmental impact and the increasing need for compliance with environmental, social, and governance (ESG) standards. Traditional energy benchmarks and sustainability certifications did not offer the granularity or climate-alignment necessary for long-term planning.
CRREM was born in 2018 as an EU Horizon 2020-funded initiative, bringing together academic institutions like University of Alicante, leading real estate players, and climate finance experts. The goal was to provide an open-source, scientifically rigorous tool that could help determine:
By leveraging Intergovernmental Panel on Climate Change (IPCC) data and integrating it into asset-level and portfolio-wide diagnostics, CRREM filled a critical void in climate risk management. The tool’s focus on granularity, transparency, and sector-specific pathways has made it widely accepted across both the private and public sectors, including support from organizations like the United Nations Environment Programme Finance Initiative (UNEP FI).
At its core, CRREM functions as a climate compass for real estate actors seeking to mitigate carbon-related risks. It provides:
This suite of tools enables retrofitting prioritization, facilitates access to green bonds, and supports climate-aligned investment decision-making, turning abstract climate targets into actionable insights.
The impact of CRREM has grown rapidly in recent years, transforming from a research initiative into a mainstream risk management and reporting tool in the real estate industry. Its integration into several global ESG frameworks underscores its relevance:
These collaborations ensure CRREM remains a central component in the evolving ESG landscape and supports the mobilization of sustainable capital toward net-zero-ready assets.
As the urgency to decarbonize intensifies, the built environment cannot afford inertia. Real estate owners, managers, and investors are increasingly expected to demonstrate how their assets align with climate goals—and CRREM offers the methodology to do just that. It enables evidence-based risk management, supports compliance with evolving regulations, and helps unlock green financing opportunities.
By offering clear decarbonization trajectories, credible stranding risk assessments, and standardized climate disclosures, CRREM empowers stakeholders to future-proof real estate portfolios in a climate-constrained world. Its growing adoption across the global market signals a broader shift toward science-aligned investment and long-term value preservation.
For real estate to play its part in the net-zero transition, tools like CRREM are not just helpful—they are indispensable. As climate expectations from governments, investors, and society continue to rise, CRREM will remain central to the real estate sector’s path forward.
