1 Adherence to the mitigation hierarchy
• A commitment to NNL
• 16 years of studies

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
