Additionality and Implementation Gaps in Voluntary Sustainability Standards

Voluntary Sustainability Standards have become a popular private governance framework for more sustainable agri-food value chains. However, recent mainstreaming efforts have increased competition between standards and driven down price premiums. This study employs a dataset of 659 Honduran coffee producers to examine whether the most widely used standards in the coffee sector (4C, Fairtrade, Fairtrade/organic, UTZ Certified and Rainforest Alliance) represent effective solutions for improving the social, environmental and economic sustainability practices of smallholder farmers under such conditions. It presents 54 farm-level indicators, compared across five standard systems, and links field results to a discussion of the strategies and governance prospects of voluntary standards. We find that no scheme has managed to grow substantially while maintaining strong additionality: commercially successful standards show little impact, while stricter schemes create high entry barriers and unresolved opportunity costs. Successful mainstreaming would require better cost coverage of sustainability improvements by value chain actors .

Automated summary

Voluntary Sustainability Standards have become popular for more sustainable agri-food value chains, but competition between standards has increased and driven down price premiums. The study finds that the most widely used standards in the coffee sector have not effectively improved the social, environmental, and economic sustainability practices of smallholder farmers under these conditions.
