The real estate industry is undergoing a major transformation, driven by new environmental requirements and growing investor expectations. While the energy performance of buildings(Scope 1 and 2) is now well regulated, Scope 3 – which accounts for up to 90% of an asset manager’scarbon footprint – remains largely underestimated. Yet it includes key elements such as building materials, renovation work and end-of-life management, and will become an essential criterion in investment and asset management decisions.
How can Scope 3 be integrated into a real estate ESG strategy and turned into a lever for value enhancement?
1. Why has Scope 3 been left out of the real estate transition?
An approach still too focused on operational carbon
Historically, carbon footprint management in real estate has focused on building energy consumption: heating, air conditioning, electricity, etc. This is known as operational carbon. This is known as operational carbon (Scopes 1 and 2).
But with the boom in energy-efficiency renovations and new building standards, direct emissions from buildings are tending to fall. On the other hand, indirect emissions, particularly those linked to materials and construction (Scope 3), remain massive and underestimated.
A largely underestimated carbon footprint
Scope 3 includes :
- Embedded carbon in materials (concrete, steel, glass, etc.).
- Emissions linked to construction and renovation work.
- The carbon impact of waste and end-of-life buildings.
These items can account for up to 90% of a building’s total carbon footprint. Failure to include them in an ESG strategy means running the risk of grossly underestimating the real environmental impact of a property portfolio.
A growing risk of asset devaluation
New regulations and pressure from investors are now pushing for Scope 3 to be taken into account. An asset manager who does not integrate it into his strategy is exposed to several risks:
- Restricted access to green financing, which requires full ESG commitments.
- A fall in the value of stranded assets, which could be excluded from the portfolios of investors committed to the low-carbon transition.
- More costly compliance, if future regulations impose strict thresholds on on-board carbon.
Given these challenges, how can Scope 3 be integrated into a high-performance ESG strategy?
2. Mapping and measuring the carbon footprint of real estate assets
The importance of an accurate Scope 3 analysis
To effectively integrate Scope 3 into an ESG strategy, the first step is to precisely quantify the carbon footprint of each asset.
This involves :
- A life cycle assessment (LCA) to evaluate the carbon embodied in materials and future emissions linked to the work.
- A mapping of the real estate portfolio to identify the assets most exposed to carbon risk.
- Integration of regulatory and financial scenarios, to anticipate future obligations and optimize investment decisions.
Modeling tools to structure a clear carbon trajectory
Asset managers can rely on Scope 3 modeling solutions to :
- Simulate several renovation or restructuring scenarios and compare their environmental impact.
- Assess optimization levers (choice of materials, reuse, waste reduction).
- Align their assets with ESG standards to secure their valuation and attractiveness.
These analyses enable us to anticipate compliance costs and structure a controlled carbon trajectory across a portfolio.
3. Optimizing materials and renovation management to reduce Scope 3
Prioritize reuse and low-carbon materials
One of the main solutions for limiting the carbon impact of real estate assets is to reduce the demand for new materials.
- Integrate reuse right from the design phase of projects to limit the purchase of new materials.
- Identify materials and equipment that can be reused during renovation and demolition projects.
- Encourage the use of low-carbon materials (low-carbon concrete, wood, bio-sourced insulation, etc.).
These choices make it possible to drastically reduce an asset’s carbon footprint while keeping construction costs under control.
Better planning of works and reduction of avoidable emissions
Energy renovations are essential, but they must be planned to minimize their carbon impact. A poorly anticipated renovation can generate higher emissions than the gains it brings in the long term.
Scope 3 modeling can be used to optimize :
- Phasing of work to avoid unnecessary or redundant work.
- Technical and material choices to maximize carbon benefits.
- Before/after monitoring of renovations to measure the gains achieved and adjust the strategy if necessary.
4. Integrating Scope 3 to secure financing and asset valuation
An increasingly important criterion for investors
Access to green financing and ESG labels is increasingly conditional on full consideration of the carbon footprint of assets.
- Banks and investment funds prefer assets with a controlled carbon trajectory.
- Environmental labels (BBCA, HQE, European taxonomy) require precise assessment of embedded carbon.
- Rigorous management of Scope 3 helps toimprove the ESG rating of assets and make them more attractive on the market.
A lever for increasing the value of real estate assets
Managers who integrate Scope 3 into their strategy enjoy several advantages:
- Easier access to sustainable financing, which requires clear emission reduction commitments.
- Greater regulatory resilience, by anticipating future standards and avoiding additional compliance costs.
- Enhanced asset valuation, by demonstrating their compatibility with carbon neutrality objectives.
Conclusion: integrating Scope 3, a necessity for sustainable real estate
Scope 3 is today the missing link in many real estate ESG strategies. With emissions representing up to 90% of the total, it is becoming imperative to integrate this dimension into asset management.
Property managers who adopt a proactive approach now will benefit from several strategic advantages:
- Better control of compliance and renovation costs.
- More attractive assets on the sustainable investment market.
- Regulatory and financial foresight to limit the risk of devaluation.
Low-carbon real estate is no longer limited to energy efficiency. The entire life cycle of buildings must now be integrated into a coherent, high-performance ESG trajectory.
