To mitigate climate change and foster sustainability, we must shift to sustainable materials and redesign products for circularity. Replacing virgin fossil feedstocks with biomass or recycled sources is essential. The mass balance approach accelerates this transition by integrating renewable feedstocks into supply chains. Addressing Scope 3 emissions and ensuring full traceability through robust certification schemes are crucial for effective decarbonization. Partnerships across the value chain are vital to drive this shift and reduce carbon emissions, advancing us towards a sustainable, circular economy.
