Research on the Establishment of Carbon Footprint Accounts of Chinese Enterprises Based on Blockchain Technology : It Is Mainly Based on the Analysis of Catl

Abstract

In response to the mandatory requirements of the EU Carbon Tariff and the New Battery Law for the full life cycle carbon management of Chinese battery enterprises, this paper takes CATL as a case to explore the construction path of a carbon footprint account driven by blockchain technology. Based on CATL's "Times Carbon Chain" platform, a three-layer technical architecture was constructed by adopting distributed ledger, perspective life cycle assessment and smart contract technologies: data layer, accounting layer and application layer. By comparing the full life cycle carbon footprint of the 1kwh lithium iron phosphate battery of BYD's subsidiary FinDreams Battery, the research found that the carbon emissions in the transportation link of CATL were significantly higher than those of the benchmark enterprises. Based on this, a multimodal transportation optimization plan was proposed. This work provides a reusable carbon management technology paradigm for Chinese enterprises to deal with international carbon barriers, which has practical value for promoting the implementation of China's carbon neutrality goal.
