The global bioeconomy is expanding rapidly, currently valued at USD 4–5 trillion and with the potential to reach USD 30 trillion by 2050. A strong bioeconomy can strengthen supply-chain resilience, advance climate and biodiversity objectives, and support sustainable growth, yet significant investment gaps persist. This policy brief highlights how blended finance, de-risking tools, market-based instruments and public–private partnerships can help mobilise private capital, and emphasises the need for coherent governance to scale sustainable biomanufacturing. It serves as a G20 background document on financing instruments and policy levers to harness biomanufacturing for climate, biodiversity and growth.
