Core Insights - The seventh Carbon Trading Market Development Conference was held in Beijing, focusing on the role of forestry carbon sinks in achieving carbon neutrality goals and the challenges faced in this area [1] Group 1: Forestry Carbon Sinks and Climate Goals - Forestry activities can absorb approximately 33% of anthropogenic greenhouse gas emissions, but they can also become sources of emissions due to disturbances [1] - The IPCC's Sixth Assessment Report indicates that the agriculture, forestry, and land use sectors could contribute 20%-30% of the global emission reductions needed for carbon neutrality between 2020 and 2050, equating to 800 million to 1.4 billion tons of CO2 equivalent annually [1] Group 2: Market Dynamics and Challenges - Although forestry carbon sink projects are not the most registered in the voluntary carbon market, they lead in trading volume and price, with a trading volume of 240 million tons in 2021, projected to drop to 37 million tons by 2024 [2] - The decline in trading volume is attributed to various challenges, including issues with carbon measurement baselines, additionality, non-permanence, potential negative impacts on biodiversity, and carbon leakage [2] Group 3: Quality Assessment and Standards - A new guideline titled "Forestry Carbon Sink Project Quality Evaluation Guidelines" was released in January 2023, proposing 30 specific indicators to create a quality assessment system that aligns with international standards while considering regional realities [3] - The guideline aims to promote high-quality development of forestry carbon sink projects, ensuring they are measurable, traceable, effective, and equitable [3]
