As coordinators of the Advisory Committee on Subnational Governments to the CBD, together with the Government of Quebec, and as partners of the Edinburgh Process, Regions4 is committed to supporting subnational leaders in their advocacy efforts towards the post-2020 Global Biodiversity Framework, to be adopted at CBD COP 15.

The post-2020 Global Biodiversity Framework is a historical opportunity for subnational governments to be recognized for the role they will play in the implementation of the new framework, but also, to define the enabling conditions that will allow its successful implementation at all levels of government.

Regions4 and its partners are aiming for a stronger than ever presence at the COP15 and as co-host of the 7th Summit for Subnational Governments & Cities: Taking Action for Biodiversity, are inviting all regions willing to put an end to biodiversity loss to join their efforts in raising regions’ voice. Visit the Programme.

Join our initiatives at CBD COP15!

The Edinburgh Declaration sets out the aspirations and commitments of the Scottish Government, Edinburgh Process partners, and the wider subnational constituency of the Convention on Biological Diversity, in delivering for nature over the coming decade. It is signed by over 260 local and subnational governments, and it will remain open for signature up until the CBD COP15.

For instructions on how to sign the Edinburgh Declaration please visit:

The Advisory Committee on Subnational Governments and Biodiversity (AC SNG) is a permanent structure officially recognised by the CBD through Decision X/22 of COP 10 that aims at bringing the voice of regions to the biodiversity agenda. Regions4, together with the government of Quebec, coordinates the AC SNG and its activities.

The Case Study Database is a collection of case studies that documents regional success stories and good practices with the objective of making them replicable and accessible to other subnational governments with similar challenges. Each case study provides detailed information on the project’s catalyst, the institutional framework that enables it, the key components of the project, their direct and indirect impacts, its financial sustainability, as well as successes and challenges among other key components. It’s a featured tool of the RegionsWithNature platform and a permanent project of Regions4, that will be formally launched at the CBD COP15.

All members of the RegionsWithNature platform are welcome to submit their case studies, as well as all Regions4 members. To learn more on how to participate and be a part of the CSD please email us at

  • Pavilion event: RegionsWithNature catalyzing biodiversity action and resources for implementation | Date 10 December 2022, 15-16:30 local time, CBD COP 15 official venue, Pavilion for Local and Subnational Governments.

A RwN partners led event highlighting the potential of the platform to catalyze regional actions and develop resources to stop biodiversity loss at the subnational level of government. The event will showcase the CaseStudyDatabase as the tool to foster knowledge exchange and capacity building at the regional level of government. Regions engaged in the CSD will share their experience on putting into practice the objectives of the CBD and translating those good practices into learning.

The 7th Summit is dedicated to taking action and making commitments, with subnational governments and cities sharing and demonstrating inspirational biodiversity initiatives, solutions and achievements, and pivoting combined multi-level ambitions and engagement into measurable actions. The Summit will center around three elements: Engage, Influence and Act.

The outcome of this historic, action-oriented Summit will be presented formally by the hosts to the CBD COP 15 High Level Segment as a united message from the subnational constituency.

Visit the Programme here.

The event will showcase the success of the Edinburgh Process, considering best practices and emerging policies at subnational level from Edinburgh Declaration signatories around the globe. It will show how the Edinburgh Process has bridged the climate and nature agendas by highlighting how actions at all levels of government can deliver global goals. More information here.

For the first time at a CBD COP, there will be a dedicated Pavilion, focusing on subnational government and city actions and opportunities. This clearly demonstrates an elevated recognition and the biodiversity community of the significant contributions of local and subnational governments towards the implementation of the GBF.

The Pavilion will showcase an exciting, packed daily program and will offer subnational governments and cities, their partners and CBD Parties more opportunities than ever before to showcase their work, learn from others, and make the links between biodiversity, climate, water security, food security, pollution and waste, the circular economy and job creation, focusing on systems-based approaches. Programme coming soon.

AC SNG & Regions4 Biodiversity Learning Platform information document 
Mainstreaming Biodiversity: The Subnational Government Experience

The report aims to bring the voice of subnational governments into the post- 2020 global biodiversity framework process and identify existing strategic actions that can help to achieve further progress on mainstreaming biodiversity. It is recognized as an information document to the 3rd meeting of the Subsidiary Body on Implementation to the CBD.

The report showcases how subnational governments contribute to the much-needed transformative change and provides information on their role in linking the different levels of government to the actions needed for mainstreaming biodiversity into and across all sectors of modern human life. It explores the potential of subnational governments and advances solutions and ideas to overcome the impediments to embedding biodiversity considerations into all sectors, and to enthusiastically advance into new paradigms, goals and societal values.
