Core Viewpoint - The article discusses the implementation of a new methodology for voluntary greenhouse gas emission reduction projects in the context of low gas recovery from onshore oil fields, aiming to enhance methane recovery, reduce carbon emissions, and promote the green transition of the oil extraction industry in China [4][5]. Summary by Sections Background - The methodology was jointly issued by the Ministry of Ecology and Environment and the National Energy Administration on November 21, 2025, to encourage broader industry participation in greenhouse gas emission reduction [4]. Principles of Methodology - **Scientific Principle**: The emission reduction mechanism must be scientifically sound and comply with industry technical standards [7]. - **Operability Principle**: The methodology should simplify monitoring parameters while ensuring data is verifiable and traceable [9]. - **Conservativeness Principle**: Emission reductions should be conservatively estimated to avoid overestimation [10]. - **Sustainable Development Principle**: Projects must align with sustainable development goals and not negatively impact the environment or socio-economic development [11]. Applicable Conditions - The methodology applies to low gas recovery projects from onshore oil fields, requiring specific conditions such as a processing capacity of at least 30,000 Nm³/d and compliance with national laws and industry policies [14][15]. Project Duration and Baseline Scenario - The project duration for emission reduction claims can last up to 10 years, with a baseline scenario established for comparison [17]. Additionality Demonstration - The projects face challenges such as complex gas composition, remote locations, and high investment costs, which necessitate additionality proof for the emission reduction claims [19][20]. Emission Reduction Calculation - Emission reductions are calculated based on the replacement of newly extracted natural gas with recovered gas, considering various emission sources [21][22]. Data Management Requirements - A robust data management system must be established, including monitoring, recording, and cross-verifying data, with a retention period of at least 10 years for all project-related data [25]. Verification and Public Oversight - Verification of emission reductions will be conducted by designated institutions, with monitoring data made publicly available through local ecological departments [27][30].

Core Viewpoint - The article discusses the implementation of a new methodology for voluntary greenhouse gas emission reduction projects related to the recovery and utilization of associated gas from offshore oil fields, aimed at promoting industry-wide participation in emission reduction efforts [4]. Background - The methodology was jointly issued by the Ministry of Ecology and Environment and the National Energy Administration on November 21, 2025, and is effective from the date of issuance [4]. - Associated gas, primarily composed of methane, ethane, propane, butane, pentane, and heavier hydrocarbons, is produced alongside oil extraction. The recovery and utilization of this gas can reduce carbon dioxide emissions, improve energy efficiency, and enhance the supply of clean energy, contributing positively to the green and low-carbon transformation of China's offshore oil industry [6]. Main Content 1. Applicable Conditions - The methodology applies to projects recovering associated gas from offshore oil fields for the production of natural gas, liquefied natural gas, compressed natural gas, and liquefied petroleum gas [12]. - Projects must have no existing pipeline connections between production facilities and land prior to approval [12]. - Monitoring data must be connected to the national carbon market management platform [12]. 2. Project Accounting Period - The accounting period for projects is defined as the time frame for which emission reductions are recorded, with a maximum duration of 10 years [16]. 3. Additionality Evidence - Projects face high construction and operational costs due to the offshore distance and dispersed sources of associated gas, which presents investment risks. Projects meeting the applicable conditions are exempt from additionality proof [20]. 4. Emission Reduction Calculation Method - Emission reductions are calculated based on the replacement of newly extracted natural gas with recovered associated gas, avoiding emissions from burning newly extracted gas [23]. 5. Data Management Requirements - Project owners must establish data management systems to ensure data quality and monitoring, with designated personnel responsible for data collection and verification [28]. - Measurement devices must be calibrated annually and maintained within their validity period [29]. - All data and information from the project design and implementation phases must be retained for at least 10 years after the final emission reduction registration [31]. 6. Approval and Verification Points - Verification institutions should refer to the methodology for applicable conditions, project boundaries, monitoring plans, and parameters during project approval and emission reduction verification [39]. 7. Public Supervision Channels - Monitoring data will be publicly accessible through the official websites of provincial and municipal ecological environment departments, allowing for public and media oversight [40].

Core Viewpoint - The article discusses the implementation of a new methodology for voluntary greenhouse gas emission reduction projects related to the recovery and utilization of gas during the testing phase of onshore gas fields, aiming to promote industry participation in emission reduction efforts [5][6]. Group 1: Background and Significance - The testing phase of onshore natural gas exploration involves flaring gas, which can be converted into usable products, thus promoting methane recovery, reducing CO2 emissions, and enhancing energy efficiency [7]. - The methodology aims to support the green and low-carbon transformation of China's natural gas extraction industry [7]. Group 2: Methodology Principles - The methodology is based on principles of scientific validity, operability, conservativeness, and sustainable development, ensuring that emission reduction projects are feasible and do not negatively impact the environment or socio-economic development [8][9]. Group 3: Applicability and Conditions - The methodology applies to onshore gas field testing projects, requiring that they meet specific conditions, including being in the testing phase and converting flared gas into marketable products [12]. - The project monitoring data must be connected to the national carbon market management platform, and the project must comply with national laws and industry policies [12]. Group 4: Project Duration and Baseline Scenario - The project duration for emission reduction claims can last up to 10 years, with specific time limits for gas recovery from different types of wells [14]. - The baseline scenario involves the direct combustion of flared gas at the well site [14]. Group 5: Emission Reduction Calculation - Emission reductions are calculated based on the replacement of newly extracted natural gas with recovered gas, avoiding emissions from the combustion of new gas [16]. - The methodology emphasizes conservative estimates for emission reductions, ensuring that calculations do not overstate the benefits [19]. Group 6: Data Management and Verification - A robust data management system is required, including quality assurance measures, calibration of measurement devices, and data archiving for at least 10 years [24]. - Verification of emission reductions will involve cross-checking monitoring data with the national carbon market management platform [27]. Group 7: Public Oversight - Monitoring data will be publicly accessible through local ecological departments' official websites, allowing for public and media scrutiny of the projects [28].
