Developing a bioeconomy can make a significant contribution averting the ongoing climate crisis and to achieve sustainable development. The BioMonitor project develops and tests a monitoring and measuring framework for the EU bioeconomy. This policy brief outlines a framework for measuring the size and development of the bioeconomy. This framework considers drivers, impacts and results that depict the development of the bioeconomy. Moreover, it presents the sectors that cover the bioeconomy and includes the indicators for monitoring and measuring development. The development of new indicators concentrates on a) those describing sectors that are part of the bio-based economy and b) those describing public and private initiatives to advance the sustainable and circular bioeconomy.
