Achieved outcomes and impacts:
More than 28 green spaces were created in a period of 20 years, equating to more than 42 hectares. This involved the planting of more than 14,000 trees over a 15 year period. The large projects being implemented under this Charter during the last five years have led to an increase of the tree heritage of more than 40%. Consequently, the territory of Nancy - with only 1500 hectares for nearly 110 000 inhabitants - has a very high proportion of natural areas: 320 hectares, including private and public spaces.
Success factors and lessons learned:
Nancy's Charter for Trees has led to significant tangible and effective outcomes and impacts, as described above. Urban afforestation supports multi-functional nature-based solutions (biodiversity, ecosystem restoration, climate change mitigation, lowered temperature, better air quality, carbon sequestration, improved soil quality, water and flood management, etc). The policy instrument is also viewed as being sustainable in the long-run since it has been proven to be accepted, prioritized and earmarked for funding since 1996. The Charter is locally appropriate and has strong potential for replication and up-scaling.
