Organisations and groups joining any PPN must select one of three pillars to which they want to belong, those pillars are:
- Community & Voluntary
- Social Inclusion
While the Environment Pillar has a set of criteria that those wishing to join it must meet (set out by The Environmental Pillar at this link www.environmentalpillar.ie/ppn/), the other two pillars have no such criteria so it is up to the group in question to decide which one fits best for them.
These pillars are each represented on the PPN Secretariat, 3 positions per pillar, and are used as broad groupings under which consultations and other activities happen.
