Incorporating carbon sink of harvested wood products into ecological footprint accounting: model and case study

Ecological footprint (EF) accounting system is widely used in assessing environmental sustainability at various spatial scales. To improve the EF performance, a new EF calculation framework was established in this study, in which HWP is considered as carbon sinks and the model was then applied to th...
