Shanghai, March 30, 2026 – The SEEK Biochar Project in Shanghai, jointly developed by the Shanghai Academy of Agricultural Sciences, SEEK Bio-Technology (Shanghai) Co., Ltd., and Climate Bridge (Shanghai) Ltd., has officially become Shanghai’s first biochar project to receive certification and issue CO₂ Removal Certificates (CORCs) on Puro.earth - the world’s leading carbon-crediting platform for durable carbon dioxide removal (CDR).

‍‍SEEK constructed and operatesthe Shanghai Jinshan District Comprehensive Utilization Base for Agricultural and Forestry Waste Resources in Lvxiang Town, an area known for its agricultural heritage, including its reputation as the hometown of flat peaches. The project’s core waste carbonization production line commenced operations in May 2025, and focuses on converting agricultural and forestry waste into biochar-based organic fertilizer. When applied to farmland, the biochar improves soil structure, enhances nutrient efficiency, and supports the restoration of degraded soils. This approach achieves durable carbon removal and long-term carbon sequestration, while increasing agricultural productivity and crop quality.

Under the professional guidance and support of Climate Bridge, the project team established comprehensive and standardized documentation and data accounting across the entire project lifecycle. This includes agricultural and forestry waste collection, pyrolysis carbonization, biochar-based fertilizer preparation, and farmland soil application. Following verification and validation by Earthood, an independent third-party validation and verification body (VVB), the project successfully met all requirements for certification and CORC issuance under Puro.earth.

Puro.earth is the world’s leading carbon-crediting platform for durable CDR. Its methodologies certify suppliers that remove carbon dioxide from the atmosphere and securely store it for at least 100 years. Certified projects are subsequently issued CORCs, which are recorded on the Puro Registry. Puro.earth is also an ICVCM-approved Eligible Carbon Crediting Program that meets the requirements of the Core Carbon Principles (CCPs) Assessment Framework for effective governance, transparency, tracking and robust independent third-party validation and verification.

This certification underscores the project’s contribution to advancing high-integrity carbon removal solutions while supporting sustainable agricultural practices and circular resource utilization.
