• Current consumption patterns and excessive resource use are key drivers of global biodiversity loss. Sufficiency is an essential strategy to reduce these pressures, by aligning consumption with ecological limits. This policy brief underlines that sufficiency must become a core pillar of policy and economic decision-making, in order to achieve transformative change towards a good life within planetary boundaries. It presents key recommendations for policy-makers, such as fostering cultural change by promoting sufficiency as a positive societal vision and regulating advertising to shift social norms. The publication underlines the importance of setting clear targets, e.g. by introducing binding material footprint limits, sectoral reduction pathways, and broadening well-being indicators beyond gross domestic product. It shows how demand-side instruments can be leveraged by reforming fiscal policy, aligning public procurement with sufficiency, and applying true cost accounting.

The policy brief also recommends supply-side instruments, such as investing in sufficiency-enabling infrastructure and adapting regulatory frameworks to support sufficiency-oriented business models. Last but not least, it urges policy-makers to assume global responsibility by promoting just, biodiversity-friendly international partnerships.…
