15of 21 compound annual growth rate (CAGR) of 22.17% and surpassing the latter since 2013. The total CO 2 emissions from the waste paper disposal phase also increased, with a CAGR of 7.76%. In comparison, the CO 2 emissions per unit of waste paper landfill are about 0.55 t, while the CO 2 emissions per unit of waste paper incineration are about 1.65 t, so the land- fill of waste paper is more conducive to the low carbon development of paper products compared to incineration.

Export Paper and Paperboard CO 2 Emissions Status 3.6. Export Paper and Paperboard CO 2 Emissions Status From a consumer responsibility perspective, CO 2 emissions from exported paper and paperboard should be subtracted from the full life-cycle CO 2 emissions of the paper prod- uct, which are shown in Table 3. From a consumer responsibility perspective, CO 2 emissions from exported paper and paperboard should be subtracted from the full life-cycle CO 2 emissions of the paper product, which are shown in Table 3.

3.7. Discussion of the Limitations of Our Analytical Results The whole-life cycle CO 2 emissions of paper products accounted for in this paper are conservative estimates, and the results of the study are subject to some limitations, mainly including: (1) With regard to the system accounting boundary, CO 2 emissions generated from the consumption of paper and paperboard, CO 2 emissions generated from road construction and repair and production and maintenance of transportation
