Sufficiency, as defined in COP26: Sufficiency should be First (external link) and included in IPCC 2022 climate mitigation report (external link) and IPCC 2023 synthesis report (external link), is articulated around 4 pillars :
1. Sufficiency is a set of policy measures and daily practices.
2. These policies and practices avoid demand for energy, materials, land, water and all natural resources.
3. These policies and practices deliver on well-being for all to ensure within country equity.
4. These policies and practices are designed within planetary boundaries to deliver on north/south and intergenerational equity.
