Application Summary AI generated

This standard specifies the method for calculating the material carbon footprint of biobased plastics by quantifying the mass of CO₂ removed from the atmosphere and incorporated into polymer molecules. It is applied in the plastics industry for lifecycle assessment and environmental labeling of biobased products, enabling manufacturers to verify carbon sequestration claims. The standard supports procurement and regulatory compliance for sustainable materials in packaging, automotive, and consumer goods sectors.
