Many industries are shifting towards bio-based alternatives to tackle the triple planetary crisis of climate change, pollution, and biodiversity loss. While biomass is touted as a solution, misconceptions about the bioeconomy exaggerate climate benefits and resource availability and omit biodiversity impacts. ECOS advocates a just and reasoned transition to a bioeconomy. With an emphasis on sufficiency, circularity, regenerative processes, healthy and zero-pollution lifecycles, and climate mitigation, this transition must provide fair opportunities to workers and local communities. This complex balancing act demands a holistic approach. We are addressing barriers and risks in EU and international policies, standards, and certifications for bioeconomy. ECOS helps create more robust and reliable international methodologies that assess the environmental impacts of bio-based products.
