我国全面启动零碳园区建设，要求绿电直供比例不低于50% 专家称有利于推动系统性低碳转型

Core Viewpoint - The recent issuance of the "Notice on the Construction of Zero Carbon Parks" by the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the National Energy Administration marks a significant shift in China's carbon governance approach, moving from individual enterprise emissions reduction to systematic, regional low-carbon transformation [1][4]. Group 1: Policy Framework - The policy document includes one main file and four supporting guidelines, which outline the basic conditions for zero carbon park construction, the application outline for national-level zero carbon parks, a trial indicator system, and carbon emission accounting methods [2]. - The notice establishes construction standards and a management framework for zero carbon parks, with application entities primarily being provincial-level development zones included in the latest "Directory of Approved Development Zones" [2]. - A tiered assessment system is created based on the annual comprehensive energy consumption scale of the parks, categorizing core indicators of unit energy consumption carbon emissions into two tiers [2]. Group 2: Emission Standards - The trial indicator system specifies carbon emission intensity requirements: parks with annual energy consumption of 200,000 to 1,000,000 tons of standard coal must have unit energy consumption carbon emissions ≤0.2 tons/ton of standard coal, while those with consumption ≥1,000,000 tons must meet ≤0.3 tons/ton [2]. - Additional guiding indicators include a clean energy consumption ratio of ≥90%, industrial solid waste comprehensive utilization rate of ≥80%, and waste heat and pressure utilization rate of ≥50% [2]. Group 3: Carbon Accounting - The "Carbon Emission Accounting Method" includes net electricity intake and industrial process emissions in a unified accounting framework, establishing a full lifecycle carbon emission accounting system [3]. - Renewable energy power obtained through green electricity direct supply or green certificate trading is assigned a carbon emission factor of 0, while other electricity is calculated using the national fossil energy power emission factor of 0.8325 kgCO/kWh [3]. - The notice emphasizes that the proportion of electricity supplied directly through green power should not be less than 50% [3]. Group 4: Economic Viability and Financial Support - The shift to park-based management for emissions reduction offers institutional advantages, allowing for the integration of land and policy incentives to encourage enterprise participation [4]. - The construction of zero carbon parks requires economic viability to achieve expected effects, alongside support from policies and financial institutions [4][5]. - The need for green financial support is highlighted, with suggestions for diversified financing models, including the establishment of special funds and the introduction of long-term capital [5]. - Innovative financial products, such as "carbon footprint-linked loans," are being piloted by some commercial banks, linking loan interest rates to the carbon reduction performance of parks [5].
