Forests play a vital role in climate change mitigation through nature‑based solutions that remove carbon dioxide from the atmosphere. Along forest biomass flows and value chains, this mitigation effect can be understood through three interconnected pillars: carbon sinks in forest ecosystems, carbon storage in long‑lived forest products, and carbon substitution through use of forest biomass for bio‑based products and materials. However, research and practice related to this forest‑based Carbon “3S” framework remain fragmented across disciplines, calling for a more integrated approach to explore their interactions and synergies.

This session will include three major components. First, keynote presentations will be delivered by 4–5 world‑leading scientists, including distinguished experts in forest carbon sinks, carbon storage, carbon substitution, ecosystem services, carbon markets, and forest‑based climate mitigation. Second, an expert roundtable discussion will be organized to identify emerging research frontiers and priority topics in the field of Carbon “3S”. Third, the session will showcase representative Chinese cases of nature‑based solutions related to Carbon “3S” through the IUFRO platform.

We are now calling for participation and contributions from the international research and professional community. For the keynote presentations, we have started to invite distinguished experts, and welcome interested experts to contact the conveners. For the roundtable discussion, we are developing a preliminary set of potential research priorities through literature review and expert consultation, and welcome further input from relevant scholars and practitioners. For the case showcase, we welcome submissions of high‑quality Chinese cases related to Carbon “3S”, and a case review committee is being established to select representative examples for presentation.

This session aims to build a shared understanding of the forest‑based Carbon “3S” framework, synthesize recent scientific advances and policy implications, and identify future research priorities. It will also provide an international platform for presenting China’s practices in nature‑based climate.
