In order to achieve the goal of carbon neutrality before 2060, it is of great practical importance to quantify the carbon sequestration potential of rice straw converted into biochar for field return in Hainan Province. Therefore, based on the life cycle assessment (LCA) method, this study evaluated the carbon sequestration potential of rice straw conversion into biochar, a major component of agriculture in Hainan Province, and discussed the carbon sequestration amount and key factors of rice straw pyrolysis conversion into biochar. The results showed that rice straw in the form of biochar in Hainan Province could achieve a carbon sequestration of 18.27 × 105 t CO2-eq, with a carbon sequestration contribution of 3.4%. This study will provide direction for rice straw utilization and carbon sequestration in Hainan Province.
