# Autodrome de Laon-Couvron (modified project) Publisher: CapexCue Canonical dossier: Dossier reference: release 1 (1d6ed2a3-9287-44f6-b455-21838aebd67e) Released project intelligence Oldest supporting observation: 2026-10-05T21:01:04.329326+00:00 Dossier released: 2026-10-16T09:34:27.558454+00:00 Source report dates and capture dates are listed per fact below; neither establishes an event date. Original released project name: Autodrome de Laon-Couvron (modified project). ## Project summary Autodrome de Laon-Couvron The environmental opinion dated 10 September 2026 describes a modified motorsport, airfield and activity-area project on the former military air base near Laon, across four communes in Aisne, France. The planned scheme includes a 3.7 km circuit and a 1,199 m airstrip, alongside activity and support facilities. The opinion says the 2018 version was not carried out and its permits expired. At the time described, MSV was seeking a new development permit; the reviewed pages do not establish a construction start or works timetable. The five planned infiltration basins are part of the autodrome project but serve rainwater management across the former base, including the separate solar project. The authority asks that the sizing assumptions be justified or reconsidered, including runoff from photovoltaic areas and expected climate changes. The opinion also identifies unresolved environmental matters, including ecological compensation, groundwater and potable-water compliance, soil information, external traffic effects and greenhouse-gas emissions. ## Evidence limits and unknowns - The reviewed opinion does not report the outcome of the modified development-permit process, a construction start or a works timetable; it calls for the works and schedule to be described. - The complete division of the former base among the autodrome, the separate solar project and other uses is not reconciled. - The authority says the compensation assessment does not demonstrate no net biodiversity loss, including when the autodrome and solar project are considered together. - The material reviewed is extracted text from pages 3–15 of the 15-page opinion. Pages 1–2 and graphical content were not interpreted, and OCR was not commissioned. Current purchasing availability: unknown. Source-dated plans do not establish current progress or available supplier packages. ## Project metadata Country: France Region: Europe Physical assets: Not classified Derived from the exact released evidence; unresolved fields remain unclassified.

It includes a 3.7 km motor circuit; a 1,199 m by 23 m airstrip using existing taxiway 2 (about 2.8 ha including clearances); an activity area with about 4,700 m² of existing buildings to be reconfigured for vehicle maintenance and other businesses; four underground fuel tanks with 230 m³ total capacity; three car parks of 990 m², 14,890 m² and 15,625 m²; and a heliport. Other planned facilities include a 31 m² entrance lodge, an 800 m² reception and exhibition space, a 1,500 m² paddock, and 550 m² for offices, race control and medical facilities. Fourteen buildings are to be demolished and another partly demolished, retaining an electrical transformer post. The revised drainage plan reduces seven infiltration basins to five and increases their stated useful volume from 13,781 m³ to 16,853 m³. The opinion reports 67 ha for the autodrome and associated buildings and 194 ha allocated to the separate Neoen project, but says the use of the former base’s remaining land needs clarification; the complete site boundary and land-use split are therefore not reconciled.

The 2018 nature-protection opinion was unfavorable. Ecological compensation required under the 2019 authorization covered 242 ha, was only partly implemented, and was interrupted in 2020; at Sissonne, 67 of 132 planned hectares had been completed. The revised assessment estimates 26.68 ha of habitat loss for the Eurasian stone-curlew and 53.36 ha of compensation, but the authority says the overall compensation assessment remains incomplete and does not demonstrate no net biodiversity loss, including cumulatively with the solar project. MSV is reported as proposing no additional compensation. The authority also reports that 2025 analyses found water from the site’s F2 borehole had parameters non-compliant with potable use, and asks for the abstraction level and measures to ensure potable-water compliance to be addressed. Soil contamination and earthworks information remain incomplete. Operating emissions are estimated at about 3,150 tCO2e per year; construction emissions were not estimated, and the claimed carbon compensation is not substantiated. Traffic effects outside the site also remain insufficiently clarified.

Leisure and sports operation is planned for daytime hours, with specified weekday and weekend limits; industrial testing is envisaged around the clock. Airfield use is limited to daylight and specified operating hours, with the dossier estimating up to 10 aircraft movements per day.

MSV subsequently modified the project and is seeking a new development permit. The reviewed pages do not establish that construction has begun or provide an implementation schedule; the authority asks for the works and timetable to be described.

The former base is described as 509 ha, with existing buildings, roads and a 94 ha airfield; it has not been used since 2012.
