摘要
The TRANS SUSTAIN project was a research project aimed at studying the impacts and outcome additionality of sustainability standards (both voluntary) and through supply chain sustainablity sourcing codes on a range of variables in relation to coffee production in three countries – Homduras, Costa Rica and Colombia. The project, whose primary data draws from surveys with close to 2000 coffee-farming households, examines the impacts of such standards across a wide range of economic, social and environmental indicators. It also develops a Voluntary Coffee Standards Index to allow comparability across schemes across all areas of sustainablity.
