a faster and more effective low-carbon development path.
5. Suggested Paths to Promote Low-Carbon Development in the Papermaking Industry
19of 21 From two dimensions and four stages of reducing CO 2 emissions and increasing car- bon sequestration, we propose the following emissions reduction strategy for the whole life cycle of paper products (Figure 8).

(1) The raw material acquisition stage. Combined with the CO 2 emissions accounting and scenario prediction results in this paper, the pulp and paper stage is the stage with the largest share of emissions in the papermaking industry (over 70%). Its en- ergy structure adjustment is the top priority for the low-carbon development of the papermaking industry. Specifically, we propose the following: Firstly, increase the application of cogeneration technology in the papermaking industry. Through co- generation technology, paper companies can use the steam generated for power gen- eration in pulp and paper production through temperature and pressure reduction, which can significantly improve the utilization rate of energy and reduce the produc- tion costs of paper companies. In this regard, in the European papermaking industry coge neration power accounted for 96% of the total electricity consumption, China’s corresponding proportion on this is less than 50%, hence, the development potential is enormous. Secondly, increase the application of biomass energy. The raw material of the papermaking industry mainly comes from plants. After extracting fiber from plants, in the pulping process by converting the remaining organic matter into bio- mass energy efficiently, it can significantly reduce the consumption of fossil energy To achieve the Sustainable Development Goals and the emission reduction targets in the INDC framework for China’s papermaking industry we will need to study more aspects beyond our current article’s focus on CO 2 emissions. The outlook from “a tree” to “a piece of paper” suggests that the whole industry chain involves more than just CO 2 emissions. In the future, we look forward to conducting more research on forests, natural gas, and biomass to promote sustainable development and achieve clean production. Nowadays, China’s papermaking industry is gradually developing into an industry with recyclable resources, low energy consumption, and low emissions, but there is still a large gap in industrial structure and energy utilization efficiency compared to developed countries’ papermaking industry. For a long time to come, China’s low-carbon development path must always adhere to the concept of green development, synergize technology, management, finance, and other multiple means.
