China Environmental Science, 2020,40(6)：2751~2757 Abstract：The inventory of carbon emissions in the life cycle of photovoltaic industry was analyzed. The carbon emissions from different scenarios for disposal stage were compared. The data for the resource, energy fluxes and environmental emissions were obtained from site investigations, published literature and new technologies development and application. It shows that the carbonemissio...
