Core Viewpoint - The third batch of CCER methodologies emphasizes the policy direction of "promoting utilization through emission reduction," introducing new methodologies for biomass power generation and oil and gas methane recovery, thus enhancing the market supply capacity of CCER projects [1][2][3] Group 1: New Methodologies - The third batch includes four methodologies: biomass grid-connected power generation, offshore oilfield associated gas recovery, onshore gas field trial gas recovery, and onshore oilfield low gas volume associated gas recovery [1][2] - The total number of CCER methodologies has reached ten since the restart of CCER [2] Group 2: Policy and Market Implications - The new methodologies aim to reduce PM2.5 pollution and carbon emissions by utilizing agricultural and forestry waste, fulfilling international commitments, and improving the profitability of high-input, low-output industries [1][3] - The methodologies are expected to enhance the market supply capacity of CCER projects, particularly in agricultural provinces like Henan and Shandong, promoting the resource utilization of agricultural waste [2][3] Group 3: Biomass Power Generation - Biomass power generation currently accounts for about 3% of renewable energy capacity but is expected to increase annually [3] - By the end of 2023, biomass power generation projects are estimated to have a total installed capacity of approximately 16.88 million kilowatts, generating an annual emission reduction of about 15 million tons [3] Group 4: Economic Viability and Challenges - The economic viability of biomass power generation projects is a core issue, with many projects facing financial challenges due to high investment costs and low internal rates of return [8][9] - The methodologies exclude projects that do not fully connect to the grid or utilize specific types of waste, focusing instead on projects that use agricultural and forestry residues [6][7] Group 5: Oil and Gas Methane Recovery - The three methodologies related to methane recovery are significant for controlling non-CO2 greenhouse gas emissions, with China aiming to achieve zero routine flaring in oil and gas extraction by 2030 [11][12] - The methodologies target different scenarios in the oil and gas sector, including offshore oilfields, onshore oilfields, and trial gas recovery from natural gas wells, each with distinct project requirements [13][14]

Group 1 - The third batch of CCER methodologies will expand the coverage of emission reduction projects, focusing on biomass energy utilization and methane reduction in the oil and gas industry, indicating a more refined and specialized direction for China's voluntary greenhouse gas reduction mechanism [2] - Compared to the first batch (carbon sinks, renewable energy) and the second batch (energy saving, gas utilization), the third batch of methodologies demonstrates increased technical complexity and industry specificity, reflecting the CCER mechanism's attention to "hard-to-abate" sectors [2] - The implementation of the new methodologies is expected to significantly enhance the economic viability of oil and gas companies in recovering associated gas, while also providing a clear pathway for biomass power generation projects to participate in the carbon market [2] Group 2 - The Ministry of Ecology and Environment has publicly solicited opinions on four new methodologies related to biomass grid-connected power generation, offshore oil field associated gas recovery, onshore gas field gas recovery, and onshore oil field low-volume associated gas recovery [1] - The first batch of CCER methodologies was released in October 2023, including four methodologies: afforestation carbon sinks, grid-connected solar thermal power generation, grid-connected offshore wind power generation, and mangrove restoration, which established specific requirements and processes for carbon sink project development [1] - The second batch of CCER methodologies was released on January 3, 2025, consisting of two methodologies: energy-saving in highway tunnel lighting systems and utilization of low-concentration gas from coal mines with methane volume concentration below 8% [1]
