碳中和约束下绿色减排体系的构建

基于对CO₂具有“既是亟待减排的温室气体，又是人类生存必不可少的可再生资源”双重性的认知，本文首次提出了碳中和约束下的“污染温室因子禁排、CO₂净零排放、调控CH₄产生和排放”的温室因子绿色减排体系。文中从两个方面提出绿色减排体系的构建：在国家层面，通过制定相关减排政策体系、进行国家超级工程和行动，为我国实现“30·60双碳目标”提供依据、标准和规范，形成实施绿色碳减排的基石和支撑体系；在微观技术层面，通过全过程控碳排放的CO₂绿色减排技术，包括源头上避免高碳排放、过程中控制碳排放、末端强化碳循环与捕集利用（3CU）等。最后指出，依靠能源绿色低碳转型，以节能降耗和生物固碳为抓手，疏堵结合，满足自然界的碳循环平衡需求，高效低成本实现经济社会高质量低碳化发展、生态文明建设与应对气候变化的三赢，将会促进我国2030年前达到峰值和2060年前实现碳中和。

Construction of green emission reduction system under the constraint of carbon neutrality

According to that CO₂ has the dual nature of “not only a greenhouse gas that needs to be reduced, but also an indispensable renewable resource for human survival”, the green emission reduction system is constructed for the first time which “prohibit the emission of polluting greenhouse factors,control net CO₂ emissions to zero,regulate CH₄ production and emission” under the constraint of carbon neutrality. At the national level, through the formulation of relevant emission reduction policy system and implementation of national super engineering and actions, the cornerstone and supporting system for the implementation of green carbon emission reduction will be formed to achieve “30·60 double carbon target” for our country. At micro technology level, through the CO₂ green emission reduction technology that controls carbon emissions throughout the whole process, high carbon emissions can be avoided at the source, carbon emissions can be controlled in the process, carbon cycle and capture utilization (3CU) can be enhanced at the end. Rely on green low carbon energy transformation, aiming at saving energy, reducing consumption and biological carbon sequestration, dredging and interception should be combination to meet the demand of natural balance of the carbon cycle. High-quality and low-carbon economic and social development, ecological civilization construction and climate change response to the triple win are achieved of low cost and high efficiency, which promote China to reach its peak by 2030 and achieve carbon neutrality by 2060.
