Carbon Flow Tracking based Carbon Emission Accounting of Low-Carbon Industrial Parks

Abstract

"3060 goal" has become an important strategic development goal of China. As industrial parks contribute 31% of the country’s carbon dioxide emissions, they naturally become the pioneer and main contributor in realizing the "dual carbon" goal, undertaking the industrial low carbon upgrading. To this end, it is urgent to help industrial parks plan green development paths, develop low-carbon parks, and facilitate industrial transformation and upgrading. However, accounting methods of greenhouse gas emissions in low-carbon industrial parks are not unified, but require in-depth discussions based upon the characteristics of individual industrial parks. Based on carbon flow tracking of industrial parks, this paper firstly analyses the accounting boundaries, energy structure, emission source and gas types, and on this basis proposes carbon emission accounting methods respectively for natural gas-fired power generation, externally purchased electrical energy, fugitive emissions and waste treatment for promoting the establishment of the greenhouse gas accounting system of low-carbon industrial parks. The empirical analysis based on an actual industrial park in Sichuan, China, verifies the applicability and practicality of the proposed methods.
