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].
