The urban recycling market in France

The national Cartofriches inventory of the Cerema (the French centre for studies and expertise on risks, environment, mobility and planning) lists 36,238 sites in France in its October 2026 version: 13,978 potential brownfield sites, 13,348 brownfield sites without a project, 7,100 brownfield sites with a project and 1,810 already converted (calculation based on Cerema). Residential brownfield sites (8,791) outnumber industrial (3,599) and commercial ones (2,174), but the type of 15,380 sites is unknown: this is the pool for urban recycling.

Launched in 2021, the Brownfield Fund (Fonds friches) received 2,999 applications over three rounds and supported 1,382 projects for €750 million, according to the Cerema. Its initial €300 million envelope was topped up by €350 million in May 2021 and then by €100 million in January 2022. Funding for urban recycling in France then continued under the Green Fund (Fonds vert) from 2023, within its measure dedicated to brownfield recycling.

According to the Brownfield Fund lessons published by the Cerema, site remediation, excluding the land purchase, costs on average €375,000 excl. VAT per hectare without pollution, and €600,000 to €800,000 per hectare where the soil or buildings are polluted, with a median of €405,000 excl. VAT. The cost can exceed €2 million per hectare. For urban recycling in France, this operating deficit accounts for most of the public aid.

Yes: office conversion is a segment of urban recycling in France, but its potential varies widely between areas. The ORIE (Observatoire régional de l’immobilier d’entreprise, the regional commercial property observatory) estimated in 2025 a potential of 127,000 to 150,000 homes in Île-de-France, according to Batiweb (March 2026). Its recycling index ranks 34 office markets: Clichy/Saint-Ouen comes first (0.65), ahead of Rueil (0.63), while Paris shows a conversion potential judged relatively limited, apart from some eastern arrondissements.

Loi n° 2021-1104 of 22 August 2021, known as Climat et résilience (the French Climate and Resilience Act), sets in its article 191 the goal of no net land take (zéro artificialisation nette) by 2050 and requires halving the consumption of land over the ten years following its enactment. Loi n° 2023-630 of 20 July 2023 makes it easier for local authorities to implement it. In France, these targets make urban recycling the main way to build without extending the city.

A PDF report in French, 2026 edition, organised in six chapters: definition and scope of urban recycling, market size and dynamics, demand for recycled land, supply and players, regulation and funding, market outlook.

Cerema data (Cartofriches, Brownfield Fund and Green Fund reviews), texts published on Légifrance, work by the Observatoire régional de l’immobilier d’entreprise and figures from the Fédération des promoteurs immobiliers. Every figure comes with its source and period.

Yes. The study is updated before it is sent, within 48 hours at most: it includes the latest published data, and every figure comes with its source and period.

Property developers, urban planners, property companies and investors, remediation consultancies, local authorities and public land agencies, as well as consultants and bankers who need to understand the urban recycling market in France.

By email, as a PDF, within 48 hours of payment. Our analysts use that time to add the latest available data before sending. You then find it in your My studies area.

A Google search or a general-purpose AI returns isolated figures, often with no date or precise scope, and cannot reach the professional press, largely behind paywalls. The study starts from a defined market, crosses public statistics with more than 500 trade journals from the IndexPresse database and links every figure to its original source. You get an up-to-date file you can cite and present as it is, without spending time cross-checking.

An invoice with VAT is emailed after every payment, and you can enter your company VAT number. For a quote, a purchase order or a bank transfer, contact us.
