四川摸清生态系统碳汇“家底”

Core Insights - Sichuan province has a significant carbon sink potential, with an average ecosystem carbon sink resource of 325 million tons CO2e from 2014 to 2024, and an estimated total asset value of 3.841 billion yuan for forest and grassland carbon sinks [1][2] Carbon Sink Resource Assessment - The report indicates that the total carbon sink in Sichuan for 2024 is projected to reach 386 million tons CO2e, with forest and grassland carbon sinks contributing 303 million tons CO2e, accounting for 78.5% of the total [2] - The core carbon sink areas are located in Ganzi, Aba, and Liangshan, which contribute 66.9% of the province's total carbon sink and 76.3% of its asset value [1][2] Potential for Carbon Sink Increase - There is still potential for increasing carbon sink resources through methods such as improving tree species and altering soil conditions, with a theoretical total potential of 350 million tons CO2e, representing an increase of 9.665 million tons CO2e or 38.1% compared to the average from 2014 to 2024 [3] Carbon Sink Resource Management Platform - A new integrated ecological carbon sink assessment platform has been launched, allowing for dynamic monitoring of carbon sink resources across Sichuan, utilizing satellite remote sensing and big data analysis [4] - The platform enables comprehensive management of carbon sink resources and asset value transformation, with capabilities for real-time monitoring and historical trend reporting [4][5] Future Development and Challenges - The platform aims to facilitate the monetization of carbon sink resources, but further steps are needed to refine product offerings and establish sales platforms [5] - Future efforts will include detailed sampling and laboratory analysis to better understand vegetation attributes, which are essential for effective commercialization of carbon sink products [5]
