a, System boundary for inventory building and GHG emissions estimation. The processes in four stages from ‘cradle’ to ‘grave’ are described here. The critical factors for net-zero emissions along paper-related sectors are annotated by light-blue tags (①–⑥). b, Schematic diagram of the carbon flows within the boundary of this study.
