The transition towards a more environmentally friendly economy can be facilitated through the bioeconomy, which relies on the use of biological resources, processes and methods to provide goods and services. However, bio-based value chains are not inherently sustainable and require careful monitoring and assessment of their impacts across all dimensions of sustainability (environmental, economic and social). Quantifying and understanding these impacts require the use of robust frameworks and methodological approaches that are currently lacking, which could be considered a gap in achieving a more sustainable bioeconomy. In this context, the objective of this research report is to fill this gap by identifying and selecting the most appropriate environmental, social and economic indicators within the Life Cycle Assessment (LCA) methodology to ensure a comprehensive assessment of environmental and socio-economic constraints and an effective analysis of bio-based value chains at all stages of the life cycle, from raw material extraction to end-of-life management. A total of 17, 26 and 101 indicators were identified for the environmental, economic and social pillars, respectively. In addition, existing gaps were highlighted, and a future framework was outlined to refine and enrich the currently available indicators and the underlying methodology.
The indicators provided constitute a building block for effectively exploring and assessing the sustainability of bio-based value chains by a wide range of stakeholders (e.g., policy makers, entrepreneurs, certification bodies) to facilitate informed decision-making, pave the way for balanced economic growth, improve social welfare and environmental protection, and overall promote more sustainable and resilient bio-based value chains.
