About ONet
The Open-ended Network of IPBES Stakeholders (ONet) is recognised and underpinned by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). ONet is a space for stakeholders to organise among the community, engage with IPBES, and support the platform's work: in service of biodiversity and nature's contributions to people.
ONet was established following a decision by the third IPBES Plenary in 2015 (Decision IPBES-3/4), and encouraged by the stakeholder community. The network is part of the IPBES Stakeholder Engagement Strategy, a novel and in some ways unique approach among institutions like IPBES.
“An important element for the relevance, effectiveness, credibility and overall success of the Platform.”
~ the third IPBES Plenary on stakeholder engagement

What we do
- ONet fosters communication between stakeholders and IPBES. We provide information on IPBES. We organise meetings between stakeholders and the IPBES Secretariat. We co-organise Stakeholder Day, our main conference, prior to each IPBES Plenary session. We coordinate stakeholder statements to IPBES Plenaries.
- We help disseminate IPBES products and achievements: for an example, see our resource page on the 2023 Invasive alien species assessment. We support capacity-building in service of biodiversity and nature's contributions to people: for an example, see our e-learning catalogues.
- ONet strengthens support for IPBES. We engage with different groups and communities. We mobilise intangible and in-kind contributions to the platform.
- We host an online space for the stakeholder community. Here you can find other stakeholders, share events, publish your news, stories and insights, and more: get involved today.

ONet membership
Membership of ONet is free of charge and comes at no financial cost. The IPBES plenary is keen to engage diverse stakeholders: it has emphasised diversity in geography, disciplines, and knowledge systems. For more detailed information on ONet, please see the terms of reference.
>> Key documents and resources
If you'd like to engage with IPBES on biodiversity and nature's contributions to people, you are a potential stakeholder: ONet welcomes both contributors to IPBES, as well as distributors and end-users of its products. Among stakeholders, we welcome policy makers and government officals at all levels, researchers of all disciplines, environment practitioners, people who hold local knowledge relevant to biodiversity, businesses and industry, community organisations, intergovernmental and non-governmental organizations, media, and communities and the public at large.

IPBES Stakeholder Registry & Networks
Alongside their participation in ONet, all members are also encouraged to join the IPBES Stakeholder Registry: you will receive official IPBES communications for stakeholders directly.
>> IPBES Stakeholder Registry
ONet is one of two IPBES stakeholder networks. The second is the International Indigenous Forum on Biodiversity and Ecosystem Services (IIFBES). All IPBES stakeholders are welcome to request to join either or both networks.
>> IIFBES
Within ONet, members with interests in the social sciences and humanities are invited to join a dedicated network:
>> SSH Network
The ONet facilitation team
The facilitation team coordinate the network and look after ONet's virtual spaces. They respond to issues relating to the IPBES work program, manage projects at ONet, and engage with the stakeholder community.
Furthermore, the facilitation team organize ONet Caucus Days and join the Quarterly Meetings of the IPBES Secretariat with stakeholders. They work with the IPBES Secretariat to plan and deliver Stakeholder Day, a conference that precedes each IPBES Plenary session. The facilitation team also coordinate IPBES stakeholders' joint efforts in crafting their statements to the IPBES Plenary.
The facilitation team normally meet on the third Wednesday of the each month throughout the year.
