This report presents the AlgaeProBANOS (APB) interdisciplinary multi-level sustainability assessment framework for the micro- and macroalgal value chains in the Baltic and North Sea region. The framework brings together insights from previous initiatives, a number of existing frameworks and academic articles, with a strong emphasis on sustainable development across environmental, economic, social and governance dimensions. It provides a methodological basis for assessing the sustainability of micro- and macroalgal value chains from these perspectives. This includes a detailed exploration of potential indicators, as well as methodologies for establishing baselines and targets. The framework emphasises the critical importance of environmental limits and constraints imposed by nature, and includes performance indicators across all dimensions – environmental, social, economic and governance. Importantly, the framework integrates multi-dimensional tools, in particular Life Cycle Assessment (LCA) tailored to micro- and macro-algal value chains. The LCA is complemented by a core set of socio-economic and governance indicators, enabling a comprehensive performance analysis across the four dimensions. This assessment is accompanied by a methodology to measure the uncertainties inherent in sustainability assessments. The framework is intended to inform key stakeholders and the public and to assist industry participants, environmental managers, and policy makers in making informed decisions about sustainable development and resilience in the algae sector.
