Environmental footprint

Sustainable and responsible
real estate company

Société de la Tour Eiffel is working to significantly reduce its environmental footprint through a proactive policy supported by clear and concrete objectives. Construction, renovation and sustainable management, support for the energy transition, adaptation to the consequences of climate change, preservation of resources, actions to promote biodiversity, best practices on a daily basis: we act as a sustainable and responsible real estate company.

CLIMATE & ASSET ADAPTATION

Société de la Tour Eiffel manages its climate-related risks and opportunities through two complementary approaches: reducing its greenhouse gas emissions and physically adapting its assets to the impacts of climate change.

Mitigation

Reducing our carbon footprint
The Mitigation Plan, co-developed with all business teams in 2022 and approved by the CSR Committee, structures reduction targets by business line (operations, development, corporate). An update towards a transition plan aligned with the CSRD requirements is currently underway.

Adaptation

Protecting assets against climate hazards
Each asset is subject to a vulnerability assessment through the Bat-Adapt platform (R4RE).
Following the 2025 update of the tool, around ten pilot assets were reassessed with enhanced granularity to refine adaptation recommendations.

Examples of adaptation actions implemented across the portfolio

  • Green roofs

Systematically considered for all development
projects to reduce urban heat island effects.

  • Cool Roof – Parc Eiffel Paris-Saclay

White reflective coating applied to rooftops ;
deployment currently being assessed across
other business parks.

  • Adivet membership (2025)

Joining this specialised network strengthens knowledge sharing on green and biosolar roofs.

  • Solar shading – Evasyon & Nanturra

Installations on two assets with high exposure
to urban heat island risks.

  • Light-coloured roof coating

Reduction of air-conditioning consumption across
operational assets as part of energy efficiency initiatives.

2019 First climate risk mapping covering the entire portfolio.

2022 Co-construction of the Mitigation Plan with operational teams and support functions.

2024 Publication of the 2nd Carbon Footprint Assessment — three scopes and breakdown by business activity (operations, development, corporate).

2025 Bat-Adapt update on 10 pilot assets · 17 DNSH-compliant buildings · Adivet membership · Nanterre renaturation project.

2026 — Outlook: Progressive update of Bat-Adapt assessments for assets eligible to align with the Top 15% of energy performance (EU Taxonomy).

  • Feasibility study for the deployment of photovoltaic panels on the rooftops of the existing portfolio.
  • Systematic feasibility assessment of renewable energy production (particularly geothermal energy) for development projects.
  • 26% of assets have renewable energy production facilities in 2025 (vs 15% in 2024) — target ≥ 80% by 2030.

 

CSRD TRANSITION PLAN — UNDER PREPARATION

→ Update of the Mitigation Plan to meet CSRD disclosure requirements

→ Progressive deployment of the harmonised CBSh and new biodiversity initiatives

→ ISO 17298 certification targeted to integrate biodiversity into the real estate company’s strategy

→ 2030 targets broken down by business line and by Department

Preserving Biodiversity & Promoting Renaturation

Société de la Tour Eiffel has been committed to biodiversity preservation for several years, with its first EcoJardin label obtained in 2015. The Company implements concrete actions to manage and protect local flora and fauna across its sites and actively contributes to the revegetation of sealed surfaces.

For all development projects, the Company engages an ecologist and/or landscape designer to ensure that biodiversity is integrated from the earliest stages and that relevant recommendations are implemented.

Notable example: the de-sealing of 27% of the EvasYon project site in Lyon, which is targeting the BiodiverCity label.

Renaturation is a key priority of the biodiversity strategy, both for existing outdoor areas and development projects.

Renaturation of Place des Nautiles at Nanterre Business Park in 2025 — creation of a renatured and welcoming community space at the heart of the park.

Green façades and the development of social areas at Eiffel Nanterre-Seine Business Park.

Green roofs systematically considered for development projects to reduce urban heat island effects and support biodiversity.

Adivet membership in 2025 to strengthen knowledge sharing on the development of green and biosolar roofs.

COMMITMENTS & OUTLOOK

Green spaces: 78% of assets in 2025 (vs 71% in 2024)

Biodiversity labels: 54% of eligible assets — target ≥ 80% by 2030

Biodiversity initiatives (nest boxes, beehives, vegetable gardens, etc.): 47% — target ≥ 80% by 2030

Harmonised CBSh: new indicator introduced in 2025, target ≥ 15% by 2030

Continued deployment of the CBSh across the entire portfolio in 2026

LIMITING RESOURCE USE AND PROMOTING CIRCULARITY

Société de la Tour Eiffel is expanding the use of circular economy principles across all works carried out on its portfolio, relying on strategic partnerships and the systematic integration of circularity considerations from the design stage.

Partnerships and Initiatives

11 operational sites implemented a circular economy approach in 2025. A new Resource Management, Circular Economy and Waste Policy was formalised in 2025.

Three-year partnership with Booster du Réemploi (since 2020), a coalition of project owners aiming to structure and scale up the demand for material reuse in construction and real estate renovation.

Partnership with Cycle Up on the EvasYon project in Lyon, dedicated to the circular economy of construction materials.

Circular economy clauses are now included in new leases for works carried out by tenants.

A Commitment to Sustainable Real Estate

Driven by its ambition to contribute beyond its own portfolio, Société de la Tour Eiffel was one of the founding members of the French Sustainable Real Estate Observatory (OID). The OID is an independent, public-interest organisation that brings together private and public stakeholders across the entire real estate value chain to promote sustainable development and innovation within the sector.

As an elected member of the Board of Directors, Société de la Tour Eiffel is also represented by Odile Batsère, the Group’s Director of CSR & Innovation, who was elected President of the OID in October 2023.

WATER CONSERVATION

The declining availability of water resources represents a major challenge, exacerbated by climate change, soil sealing and biodiversity loss. Société de la Tour Eiffel has developed a sustainable water management policy (updated in January 2023) structured around four key pillars.
  • Indoor water management
  • Stormwater management
  • Outdoor space management
  • Wastewater management

  • Installation of water-efficient equipment across operational assets, with shutdown during periods of vacancy.

  • Selection of plant species during the design phase based on their water efficiency.

  • 5 assets incorporated rainwater storage tanks in 2025, with reuse for green spaces; the Manufacture asset in Lyon is the first site in the portfolio equipped with a greywater treatment system.

  • Creation of green terraces supplied with rainwater, notably at the Suresnes asset.

  • Deployment of water meters with remote reading capabilities: 83% of assets covered in 2025 (vs 32% in 2024), a key lever for identifying and reducing leaks.

2030 TARGETS

  • ≥ 30% of assets with rainwater harvesting systems (10% in 2025)
  • ≥ 15% of assets with greywater treatment and reuse systems (2% in 2025)
  • Absolute water consumption target to be defined in 2026, based on reliable water flow diagrams
  • 100% of water meters equipped with remote reading capabilities for real-time monitoring (83% achieved in 2025)
  • Annual reduction in water intensity across all areas managed by the Company
