〇Green Carbon’s booth at the Event
◆Background of Our Presentation at the Event
Green Carbon is engaged in the creation of nature-based carbon credits, primarily in Southeast Asia, and operates projects across a wide range of fields including forest conservation, rice paddies, mangrove planting, methane reduction from cattle, and biochar initiatives. The company’s credits are currently compatible not only with JCM and Premium TVER, but also with international certification standards such as Puro.earth, Verra, and Gold Standard, supplying both domestic and overseas companies.
The purpose of exhibiting at the event was to gain networking opportunities with carbon credit purchasers, project investors, and co-development partners in the ASEAN region.
〈Presentation Overview〉
Under the theme “Nature-Based Climate Solutions from Southeast Asia – Scalable, Investable, Verifiable,” Green Carbon introduced project examples in AWD, biochar, and mangrove restoration across ASEAN, as well as the process of converting these projects into internationally tradable carbon credits. The presentation particularly emphasized:
- Development models for agriculture-based credits effective for Scope 3 emissions reduction
- Applicability and certification track record for JCM, Puro.earth, Verra, Premium TVER, and other standards
- Collaboration examples with investors through a pre-investment business model
- Implementation capability and credibility through partnerships with local farmers and research institutions
Following the presentation, the session drew strong interest from multiple participants, including financial institutions, manufacturers, and ESG investment funds.
＜Event Response and Business Discussions＞
During the three-day event, Green Carbon held discussions and exchanges with dozens of key players across a wide range of industries, including financial institutions with strong interest in sustainability, energy companies, renewable energy startups, biomass-related businesses, and manufacturers aiming to reduce emissions.
●Proposals for purchasing carbon credits to reduce Scope 3 emissions
●Discussions on joint development and potential purchase of biochar using agricultural residues
●Co-creation projects combining forest and mangrove restoration with community support
●Engagements for linking carbon credits with ESG-focused investment funds
These discussions have generated numerous concrete collaboration opportunities. Moving forward, Green Carbon will leverage these dialogues to advance joint PoCs and MoUs, accelerating project implementation across the ASEAN region.
※1: Joint Crediting Mechanism (JCM)
A system where Japan facilitates the diffusion of decarbonizing technologies and infrastructure in partner countries. The resulting GHG emission reductions are assessed as contributions by both Japan and the partner country, and the generated carbon credits are shared between the two nations.
※2: Premium T-VER
A high-quality voluntary credit scheme promoted by the Thai government. It issues reliable carbon credits for companies and municipalities through strict monitoring, verification, and registration procedures in compliance with international standards.
※3: puro earth
puro earth is the world’s first global certification institution in the B2B market focused on the long-term removal of atmospheric carbon. By publishing verified CO₂ removal certifications (CORCs), puro earth is putting effort in calling for the reduction and prevention of CO₂ emissions by collaborating with corporations and carbon negative technology suppliers. This institution is also in the current frontline for developing carbon sequestration methodologies, through biochar, carbonized building materials, and carbon capture sequestration.
※4：Verra
Founded in 2005 by three organizations: The International Emissions Trading Association (IETA), The World Business Council for Sustainable Development (WBCSD), and The Climate Group. It is currently managed by a private entity named Verra. VCS (Verified Carbon Standard) refers to the world’s most widely used standard for certifying credits issued from greenhouse gas reduction projects undertaken by companies, organizations, and individuals. It allows greenhouse gas emission reductions or removals to be treated as credits and has gained attention in recent years. Credits certify that the greenhouse gas reductions are credible and make them tradable like general commodities.
