Analysis of Carbon Footprint Assessment and Accounting System of Photovoltaic Industry under Dual-Carbon Background

With the intensification of global climate change and the growing demand for the Sustainable Development Goals (SDGs), dual-carbon policies are on the rise globally, bringing new challenges and opportunities to the energy industry. Focusing on the photovoltaic (PV) industry, this study carries out a carbon footprint analysis in the context of dual-carbon to gain a comprehensive understanding of the current status of PV modules in terms of carbon emissions and emission reduction measures. This paper firstly summarizes the development of the PV industry, and deeply analyzes the relevant theories and methods of carbon footprint assessment and accounting system. Then, it systematically evaluates the carbon emissions of crystalline silicon PV modules throughout their life cycle, and based on this, it puts forward suggestions on strategies to reduce the carbon footprint. Finally, the opportunities and challenges that the PV industry may encounter in the process of moving towards a low-carbon future are discussed to provide a reference for decision-making and practice in this field.
