1 Adherence to the mitigation hierarchy

• A commitment to NNL

• 16 years of studies

• 10 years of land stock anticipation

• Autorisation files with a mitigation hierachy structure

and requirements

• A follow-up above regulation

27/11/2018 14BBOP 15 CONFERENCE – PARIS

2 Limits to what can be offset

• No protected area impacted

• No “in critical danger” species impacted

• No residual impacts with a “high” or

“very high” stake for protected species

• 2.000 ha of land availability close

to the impacts

• Early site securing

27/11/2018 15BBOP 15 CONFERENCE – PARIS

3 Landscape context

• Hard land pressure context

• Integration of regional ecological

schemes

• Green and Blue corridors study

• No integration into land planning

documents

• Analysis of known cumulated

impacts
