加强标准规则衔接，夯实碳市场建设的技术基础。数据是碳市场运行的基础，如果各部门数据采集标准 各异，不仅将影响配额分配与交易效率，也将成为制度衔接的突出障碍。建议构建全国统一的碳排放核 算、监测、报告与核查（MRV）体系，整合来自不同部门的碳排放数据、经济数据、消费数据等，制 定统一的碳排放核算指南与数据接口规范，实现数据实时比对与交叉验证。特别是在新一轮NDC目标 下，加强与国际标准对接，提升数据可比性与互认度，对增强我国碳市场的公信力至关重要。可引入区 块链、物联网等技术实现数据实时采集与防篡改，并明确企业、核查机构、交易所的数据报送义务与质 量责任。同时，应强制披露重点行业碳排放强度、配额清缴情况等信息，并建立数据纠偏机制，对异常 值进行跨部门联合核查。此举将提升数据权威性与协同效率，为配额分配、金融衍生品创新及跨市场联 动提供支撑。 加强配额分配衔接，增强碳市场运行的经济激励。配额分配是碳市场核心环节，其与宏观经济政策、行 业政策的衔接直接影响减排成本与市场公平。当前以免费分配为主的方式难以充分反映行业差异与减排 潜力，且与电力、钢铁等行业政策协调不足。可逐步提高有偿分配比例，通过经济手段强化政策协同。 ...

Group 1: NDC Goals and Climate Ambitions - The new NDC targets announced by China aim for a 7% to 10% reduction in net greenhouse gas emissions by 2035 compared to peak levels, with non-fossil energy consumption exceeding 30% of total energy consumption [1][2] - The NDC goals reflect a shift from "phase-based reduction" to "systemic transformation" in China's climate governance strategy, marking a significant evolution in its approach [2][3] - The updated NDC includes a broader scope covering all greenhouse gases, moving from relative intensity targets to absolute total emission reduction metrics [3] Group 2: Implementation and Sectoral Changes - To achieve the non-fossil energy consumption target, an annual increase of 0.94 percentage points is required, necessitating a high proportion of renewable energy supply and electrification [4] - The national carbon market is set to expand, with major industries like steel, cement, and aluminum included by 2025, increasing the controlled carbon emissions from 5 billion tons to 8 billion tons [4][6] - Different industries will face varying costs for emission reductions, with sectors like steel and electricity having lower costs compared to aviation and shipping, which may incur significantly higher costs [7] Group 3: International Context and Challenges - The global progress on emission reductions is lagging, with the UN Secretary-General warning of risks to the 1.5°C temperature goal, highlighting the importance of China's NDC commitments in this context [8][9] - The EU aims to reduce greenhouse gas emissions by 66% to 72% by 2035 based on 1990 levels, although the final commitments are still pending [8] - The absence of the U.S. at the climate summit and its historical role as a major emitter complicates international climate cooperation, emphasizing the need for responsible leadership from countries like China [9]

Group 1: NDC Goals and Climate Commitments - The new NDC targets announced by China aim for a 7% to 10% reduction in net greenhouse gas emissions from peak levels by 2035, with non-fossil energy consumption exceeding 30% of total energy consumption [1][2] - The NDC goals represent a shift from "phase-based reduction" to "systematic transformation," indicating a comprehensive approach to climate governance [2][3] - The updated NDC includes a broader scope covering all greenhouse gases, a shift from relative intensity targets to absolute total emission targets, and an extended timeline that includes post-peak reduction phases [3] Group 2: Industry Implications and Actions - The transition to total emissions control means that more industries must actively engage in carbon reduction efforts, with a focus on systematic management across all economic sectors [5][6] - The national carbon market is set to expand, with plans to include major industrial sectors by 2027, increasing the number of monitored entities and the total carbon emissions under management [6] - Different industries will face varying costs for carbon reduction, with some sectors like steel and electricity having higher costs compared to others, necessitating a phased approach to implementation [7] Group 3: International Context and Challenges - The global progress on emission reductions is lagging, with significant gaps between national commitments and the efforts needed to meet climate goals, particularly in light of the U.S. withdrawal from the Paris Agreement [8][9] - China's NDC commitments are seen as crucial for setting a roadmap for carbon reduction in the next five years, especially given the challenges posed by the current international climate cooperation landscape [8][9]
