英文摘要: Carbon labelling is a marketable expression of the product carbon footprint, which has gained increasing attention of companies and consumers in recent years. Carbon labeling can effectively mitigate global climate change by quantifying the greenhouse gas emissions along product's life-cycle (i.e., product carbon footprint), and promote the behavior of enterprises and individuals through the supply chains and consumption. However, product carbon footprint assessment relies on the specific accounting standards. There are many different kinds of product carbon footprint standards around the world, which hold different accounting rules. Thus, it is difficult to compare the results with each other. Here, we compared the three most popular international standards, which are PAS2050, GHG Protocol and ISO14067, and identified eight aspects that these three standards had different requirements on, and took the uncoated printing paper as an example to quantify the impact of the different regulations between these standards. These differences are proved to be significant to the accounting results of carbon footprint of uncoated printing paper, i.e., the results calculated by GHG Protocol and ISO14067 are 61% and 49% higher than that by PAS2050 respectively; and the differences in "carbon storage, consumer transportation, capital goods and delayed emission weighted impact" have significant impacts on the carbon footprint of uncoated printing paper. We suggested, a unified accounting standard based on the product category is basic to the comparison of carbon labels, and more clear provisions of standards are necessary to reduce the uncertainty of product carbon footprints. © 2020, Science Press.
