France is implementing various environmental and energy regulations affecting the transport, commercial, and housing sectors. Under the ‘Décret tertiaire’, owners of commercial buildings exceeding 1,000 square meters must adhere to mandatory energy reduction targets, aiming for a 40% reduction by 2030, 50% by 2040, and 60% by 2050.

In the transport sector, regulations include the continued application of Low Emission Zones (ZFE) in approximately forty urban areas. As of July 1, 2026, light commercial vehicles over 2.5 tonnes used for moving services or international freight must utilize second-generation smart tachographs. The scope of mandatory energy audits for transport companies is also set to expand starting October 11, 2026.

Regarding housing and energy efficiency, the Diagnostic de Performance Énergétique (DPE) is driving significant market shifts. As of January 1, 2025, properties classified as G are prohibited from being rented, with bans for F-rated properties expected in 2028 and E-rated properties in 2034. A regulatory change on January 1, 2026, reduced the electricity-to-primary energy conversion coefficient from 2.3 to 1.9, allowing some electrically heated homes to move up one energy class. Experts warn that obsolete diagnostics could result in a 10% to 20% loss in property market value.

Effective September 1, 2026, the MaPrimeRénov’ program has reduced the scope of eligible energy-saving works, excluding certain ventilation systems, standalone insulation, and heat pumps using fossil fuel backups. However, specific subsidies remain for Mayotte to address its unique climate. Additionally, the ‘polluter-pays’ principle now applies to PFAS, requiring industrial polluters to take financial responsibility for these substances.
