Climate and Resilience Act (2021-1104)
The French Climate and Resilience Act of 22 August 2021 (article 191) enshrines the Net Zero Land Take objective by 2050, with an intermediate milestone in 2031. It is the legal basis for the whole ZAN framework.
The framework
A national target, applied parcel by parcel.
The 2021 Climate and Resilience Act set France a binding land-use trajectory: halve the consumption of natural, agricultural and forest land by 2031 compared with the previous decade, and reach no net artificialisation by 2050. What makes it operative is not the target itself but the way it descends: from national, to regional, to local planning documents, until it becomes a constraint on a specific parcel.
That descent is why the target reached developers before most of them noticed. A project is not refused for breaching a national objective; it is refused because the local plan has no remaining allocation, which is the same thing arriving through a different door.
Consequences
Two definitions, and they are not interchangeable.
The law works with two distinct notions: land consumption, used for the 2031 milestone, and artificialisation, used for 2050. They are measured differently and a project can perform well on one and badly on the other. Files that treat them as synonyms produce arguments that do not answer the question asked.
The practical effect is a reordering of design: density, reuse of already-built land, and compensatory renaturation become the levers, and brownfield redevelopment becomes the main route to new capacity.

The trajectory reaches projects through several distinct mechanisms.
- Net Zero Land Take — the overall framework
- The 2031-2050 trajectory — how the budget decreases
- Regional and local planning — where the allocation is decided
- Brownfield redevelopment — the main route to new capacity
- Compensatory renaturation — restoring artificialised land
- National-scale projects — the accounting exception
- Working with land developers — where the constraint is felt first
- Working with local authorities — who holds the allocation
