The Tibetan grassland ecosystems possess significant carbon sink potential and have room for improved carbon sequestration processes. This research investigated the rationale and urgency behind implementing Nature-based Solutions (NbS) on sequestering carbon using literature review and meta-analysis. Model simulations projected increased carbon sink in Tibetan Plateau grassland ecosystems (15–21 tetragrams of carbon by 2060) with NbS projects. A four-stage NbS framework (theory, identification, practice, goal) integrating grassland restoration and carbon sequestration was defined, incorporating traditional Tibetan knowledge. The framework optimized ecological restoration techniques and evaluated annual carbon sink changes under different socioeconomic scenarios.
