摘要

目标:中国是烟草生产和消费大国。在碳市场的建设和发展中,烟草行业有望通过参与碳交易来实现节能减排,特别是关注基于减排的森林碳汇需求。与烟草行业相比,重污染行业对碳市场的参与更深入、更广泛。因此,本文以火电和钢铁行业为研究对象,旨在为烟草行业的减排路径提供一些启示。它考虑了2005-2017年中国火电和钢铁行业之间的二氧化碳排放强度和边际减排成本,并量化了这两个行业的森林固碳需求水平,以说明森林在中国绿色低碳发展中的作用和潜力。方法:采用逻辑算法反映FCS需求、MAC等影响因素之间的关系,采用云模型模拟不同场景下的FCS需求。结果:在此期间,两个行业的碳强度分别平均下降了54.06%和56.05%。试点项目的年均MAC为11.82–25.55元/吨,而火电和钢铁行业的FCS年需求预期分别为3500万吨和4500万吨。如果MAC增加10%,FCS的年需求量将分别增加到9000万吨和5000万吨。碳排放权价格、碳排放配额和行业产出等其他因素对FCS需求影响不大。结论:应综合考虑不同行业减排的经济和技术效率,并调整碳市场中FCS的消费者对生产者补贴,以优化资源分配。这将促进减排,刺激FCS需求,并完善碳市场机制。

Forest Carbon Sequestration Demand Based on Emissions Reduction in China’s Thermal Power and Steel Industries: Implications for Tobacco Industry
Objectives: China is a large country of tobacco production and consumption. In the construction and development of carbon market, the tobacco industry is expected to realizing energy conservation and emission reduction by participating in carbon trading, especially focusing on the forest carbon sequestration demand based on emissions reduction. Compared with the tobacco industry, the heavy pollution industries participate in the carbon market more deeply and widely. Therefore, this paper takes thermal power and steel industries as the research object, in order to provide some implications for the emission reduction path of tobacco industry. It considers the CO2 emissions intensity and marginal abatement costs (MAC) between China’s thermal power and steel industries during 2005–2017, and quantifies the forest carbon sequestration (FCS) demand level of these two industries to account for the role and potential of the forests for China’s green and low-carbon development. Methods: It uses a logistic algorithm to reflect the relationship among FCS demand, MAC and other influencing factors, and the cloud model to simulate FCS demand in different scenarios. Results: It shows an average decline of 54.06% and 56.05% in the carbon intensity of the two industries over the period. The average annualMAC are 11.82–25.55 CNY/ton across pilots, while the annual FCS demand expectation is 35 and 45 million tons for the thermal power and steel industries, respectively. If the MAC increases by 10%, the annual FCS demand will increase to 90 and 50 million tons, respectively. Other factors such as the prices of carbon emissions rights, carbon emission quotas, and industry output show little effect on FCS demand. Conclusion: The economic and technological efficiency of emissions reduction in different industries should be considered comprehensively, and that the consumer to producer subsidy for FCS in the carbon market should be adjusted for resource distribution optimization. This would promote emissions reduction, stimulate FCS demand, and improve the carbon market mechanism.
