Abstract:

As one of the key market mechanisms for achieving China's "dual carbon goals," the official relaunch of the national voluntary greenhouse gas emission reduction trading market presents new opportunities for methane mitigation projects. Against this backdrop, this paper reviews the development history of the CCER mechanism, highlighting its evolution from initial exploration to a more standardized framework as a crucial component of China's voluntary emission reduction system. The relaunch of CCER has significantly increased the activity of the carbon market, encouraged greater participation from oil and gas enterprises in methane reduction, and promoted improvements in relevant policies and technical standards.Based on this, the paper conducts an in-depth analysis of the prerequisites for developing methane mitigation methodologies. First, it identifies and categorizes the current status of methane mitigation methodologies in the oil and gas sector at both international and domestic levels. Second, it evaluates the conditions for methodology development in terms of policy support, development benefits, and technical feasibility. Finally, it defines the critical elements of project design documents, focusing on key aspects such as project boundary delineation, baseline emission calculations, additionality demonstration, and monitoring plan formulation.Combining the feasibility analysis of methane reduction methodology development, the paper provides targeted recommendations for stakeholders involved in the process. At present, the domestic oil and gas industry faces multiple challenges in methodology development, including insufficient technical and monitoring capabilities, an incomplete methodological system, the lack of unified standards, and inadequate policy support. To promote the green transition of the oil and gas sector, it is essential to continuously optimize technical guidelines and policy frameworks, improve the development and application of methodologies, and effectively contribute to achieving China's "dual carbon goals."
