Carbone 4

We draw on our in-depth knowledge of the sector and our collaboration with all stakeholders: from the investment, project development, and real estate asset management sectors to construction companies and materials suppliers.

Heavily dependent on fossil fuels and materials from heavy industry (steel, cement, aluminum), the sector is on the front lines of rising energy costs and dwindling resources. In 2024, the residential and commercial sector accounted for 45% of France’s final energy consumption, 35% of which came from imported fossil fuels: the transition to low-carbon building materials and construction methods is now unavoidable.

The regulatory framework that has governed the real estate sector for several years now (Zero Net Land Take Regulations, 2020 Environmental Regulations, Climate and Resilience Law, etc.) has brought about a profound and rapid transformation in practices ranging from design to the revitalization of existing buildings. The sector must now reinvent its business and operational models to balance environmental performance with the sustainability of its operations.

Between climate-related uncertainties and stricter regulations (Tertiary Sector Decree, Energy Performance Certificate), renovation is becoming essential for resilience. Owners and operators who fail to plan for energy-efficient renovations of their properties—including switching to alternative energy sources, insulation, renewable energy, and low-carbon materials—risk seeing their properties lose value and appeal under combined pressure from regulators, investors, and occupants.

Assessment of a company’s or product’s emissions and definition of a reduction pathway based on SBT and/or national or regional law carbon strategies (e.g. EU climate neutrality goals, net-zero commitments). Support for the implementation of action plans (team training and coaching, project management, governance) to ensure that these transformations are sustainably embedded.

Assessing the Vulnerability of Real Estate Sites and Portfolios to Climate Change Using Our Tools OCARA (for sites, buildings, and infrastructure) and CIARA (for infrastructure portfolios), which helps guide investment decisions and develop effective adaptation strategies.

Assessment of the pressures your activities place on biodiversity. Development of an action plan to reduce these impacts and contribute to ecosystem regeneration at every stage of the real estate value chain, along with support for implementation.

Conducting technical and economic studies to help you make informed decisions about technologies and investments by analyzing the actual performance of your low-carbon solutions, quantifying your avoided emissions (reuse and recycling, construction processes, operations), and analyzing the impact of regulations (Zero Net Land Take Regulations, EU ETS, CBAM, 2020 Environmental Regulations, ESC, CSRD…).

Identify risks and opportunities to guide your strategies, based on our analysis of trends in demand, costs, supply chains, and competitive dynamics under various future scenarios.

A custom study? Expert input on your specific topics? Adaptation strategy or biodiversity?

Find out how Legendre, an integrated construction and real estate company, collaborated with Carbone 4 to develop its first Group carbon footprint assessment.

This approach made it possible to collaboratively develop a costed action plan and design a customized calculation tool that provides both strategic and operational insights.

Thanks to this support, which focuses on data management and skills development, the company has built lasting internal capacity to ensure independent, sustainable, and day-to-day management of its decarbonization path.
