An apartment rated G since the 2023 assessment, a landlord convinced to rent “for a few more years”: since January 1, 2025, this housing is legally indecent and is removed from the rental market. For those looking to invest their money in real estate while adhering to environmental and social criteria, this regulatory reality redefines priorities.
Ethical real estate is not just about ticking a green box on a brochure: it requires checking what you are buying, who you entrust with the management, and according to what standards the property will be operated.
DPE Schedule and Rental Bans: The Non-Negotiable Filter
We often talk about values and convictions when discussing responsible investment. In practice, the first question is more brutal: will the property you are targeting still be rentable in three years?
The Climate and Resilience Law has set a precise schedule. Properties rated G have been banned from rental since January 2025. Properties rated F will be excluded from the rental market in January 2028, followed by those rated E in 2034. This is not a recommendation: it is a prohibition that also applies during the renewal or tacit extension of the lease.
For an investor, this means that buying an F or G property without a renovation budget amounts to acquiring an asset that will lose its rental capacity in the short term. An ethical investment therefore systematically includes a renovation plan compatible with these deadlines.
Since January 1, 2026, the conversion coefficient of electricity to primary energy used in the DPE has changed from 2.3 to 1.9. Properties heated by electricity automatically gain a better rating. A property rated E with electric heating can shift to D without any work, simply due to this update.
This can be seen as a boon, provided one understands that the DPE grid will continue to evolve and that a new tightening is already planned, with a coefficient expected to be 1.7.
Exploring offers of ethical real estate on the Breizh Equitable site allows one to identify properties whose energy performance is already aligned with these regulatory constraints.
ISR Real Estate Label: What Certification Changes Concretely
The ISR (socially responsible investment) label has been adapted for real estate funds, particularly SCPI and OPCI. It is based on ESG criteria: environmental, social, and governance. On paper, it is a mark of seriousness. In practice, one needs to look closer.
What the Label Requires from Management Companies
A certified ISR SCPI must measure and publish indicators on the energy consumption of its portfolio, its carbon emissions, the quality of life in the buildings, and the transparency of its governance. The label requires setting measurable improvement objectives, not just declaring good intentions.
Some investors feel that the label still lacks bite on the social pillar. Management companies rarely go beyond improving comfort in the building, without addressing issues of accessibility or social diversity in depth.
Check Beyond the Label
Before subscribing to an ISR-labeled SCPI, one can examine several concrete elements:
- The share of the real estate portfolio actually certified HQE, Bepos, or equivalent, and not just “in the process of certification”
- The energy renovation schedule of the assets held, with precise deadlines aligned with the Climate and Resilience Law
- The rental management policy: lease duration, rent control, accessibility of housing for low-income households
- The published annual ESG reports, which must detail the progress made and not just the objectives set
A fund that displays the label without publishing a detailed ESG report deserves skepticism. The ISR label is a starting point, not a guarantee of ethical profitability.
Profitability and Ethical Investment: Arbitrating Without Deceiving Oneself
It is often heard that sustainable real estate “yields as much” as traditional real estate. The reality is more nuanced and depends on the type of investment chosen.
In direct purchase, renovating a property to achieve an A or B rating represents a significant initial cost. This additional cost can be partially recovered through stable rents (a well-insulated property attracts tenants who stay longer) and a higher asset valuation in the resale market. But the profitability horizon is longer compared to a traditional investment.
In stone-paper, ISR-labeled SCPIs show yields comparable to traditional SCPIs in recent years. The difference lies in the resilience of the portfolio: a portfolio composed of energy-efficient buildings suffers less regulatory devaluation when DPE thresholds tighten.
Cost Items Not to Underestimate in Direct Purchase
When buying a property to renovate according to ethical criteria, three budget items are often underestimated: the preliminary energy audit (distinct from the simple DPE), the choice of bio-sourced materials whose cost exceeds that of conventional insulation, and compliance with accessibility standards if the property is intended for social or intermediate housing.
Not integrating these lines into the initial financing plan risks compromising the quality of the work or delaying projects that will determine the future rental compliance of the property.
ESG Criteria Applied to a Concrete Real Estate Purchase
ESG criteria are not reserved for institutional funds. They can be transposed to a personal purchase by asking three sets of questions before signing.
- Environment: what is the current DPE class and projected after renovations? Does the building use low-carbon footprint materials? Is the plot exposed to an identified climate risk (flooding, clay shrink-swell)?
- Social: is the property located in a tense area where affordable housing is lacking? Is the proposed rent compatible with the median incomes of the neighborhood? Is the housing suitable for aging or disability?
- Governance: if the purchase is through a SCI or a collective arrangement, are the decision-making rules transparent? Do the partners (syndic, manager) apply documented responsible practices?
Applying this grid does not guarantee a superior return. It ensures that the investment does not rely on negative externalities that will ultimately be costly, in imposed works, rental vacancy, or regulatory depreciation.
Ethical real estate is built on verifiable constraints, not on brochure promises. The DPE schedule, the ISR label, and the ESG criteria provide a framework. The rest depends on the rigor with which it is applied to each property, each lease, each renovation arbitration.
