RESUMO

Abstract This paper provides a simplified life cycle based assessment for a local branded pure milk product, to measure its related carbon footprint, including production of raw milk, dairy processing, transportation of milk product and disposal of packaging waste. The results show that the total carbon footprint of the pure milk is 1120g CO2/L. The production of raw milk is identified as the major contributor to the carbon footprint. This contribution has amounted to 843 g of CO2 per liter of pure milk, accounted for 75.27% of the total carbon footprint. The carbon footprint of product transportation is 38 g of CO2 per liter, which accounts for 3.39% of the total. The carbon footprint related to the dairy processing and disposal of waste packaging is 173 g of CO2 per liter and 66 g of CO2 per liter, accounting for 15.45% and 5.89% of the total, respectively. The carbon footprint assessment intends to help dairy enterprises identify the intensive sectors of carbon emissions, and provides insight into improvement of product environmental performances.
