Since 1960s, the percentage of recover paper pulp in the global papermaking pulp was increased continuously. Therefore, the original computation method of paper ecological footprint, based on the wood consumption of pure wood pulp, need to improve. The author researched the impact of paper recycle utilization to papermaking wood consumption according to analyze pulp construction change, relationship of pulp and paper, pulp wood consumption and recover paper pulp conversion rate etc. It is concluded that 1 ton paper consume 3.879 m3 wood less than original 4 m3. Based on this, the author re-counted 1 ton paper ecological footprint is 2.569 hm2 forest. Compared with the previously research, the result is more reasonable.
