Senken 與 Carbonsate 簽署 5 萬噸生質儲存碳移除協議

Senken 與 Carbonsate 公布多年期採購協議，將由納米比亞的生質儲存專案交付 5 萬噸永久碳移除。雙方表示交付期自 2026 年延續至 2028 年。

Senken and Carbonsate announced a multi-year purchase agreement covering 50,000 tonnes of permanent carbon removal from a biomass storage project in Namibia. Deliveries are planned from 2026 through 2028.

Carbonsate 的方法是將原本可能分解或燃燒的廢棄木質生質材料，置入工程化地下儲存環境。Senken 則透過碳移除採購平台評估與媒合信用。

Carbonsate's approach stores waste woody biomass that might otherwise decompose or burn in engineered underground conditions. Senken operates a platform that evaluates and connects carbon-removal supply with buyers.

生質碳移除的核心風險在於額外性、材料來源、長期耐久性與洩漏控制。大量採購若缺少可追溯方法與持續監測，便難以支持企業的氣候主張。

Biomass carbon removal depends on additionality, feedstock provenance, long-term durability and leakage controls. Large purchases cannot support credible climate claims without traceable methods and continuing monitoring.

依來源說明，專案將使用專有監測、報告與查證系統，並以 Puro.earth 方法驗證。買方仍應保存合約批次、交付年份、專案邊界與註銷紀錄。

The source says the project will use a proprietary monitoring, reporting and verification system and Puro.earth verification. Buyers should also preserve contract batches, delivery years, project boundaries and retirement records.

協議涵蓋 5 萬噸移除量，Carbonsate 稱其為歐洲規模最大的生質儲存採購之一。Senken 表示平台以超過 600 個資料點審查專案，並淘汰約 95% 候選信用。這些均為公司陳述，仍需編輯核對。

The agreement covers 50,000 tonnes. Carbonsate describes it as one of Europe's largest biomass-storage purchases. Senken says its platform assesses more than 600 data points and rejects about 95 percent of candidate credits. These are company claims requiring editorial verification.

交易顯示耐久碳移除市場正從小額試購走向多年期承購。企業採購標準也可能進一步聚焦交付風險、耐久年限、MRV 與信用註銷證據。

The transaction indicates that durable carbon removal is moving from small trials toward multi-year offtake. Procurement standards may increasingly focus on delivery risk, durability, MRV and evidence of credit retirement.

SNN 編輯分析：採購噸數不是環境完整性的替代指標。可信度取決於每批材料、儲存位置、監測結果與信用生命週期能否形成可驗證證據鏈。

SNN editorial analysis: Purchased tonnage is not a substitute for environmental integrity. Credibility depends on a verifiable chain connecting each feedstock batch, storage location, monitoring result and credit lifecycle.

後續應追蹤 2026 年首批交付、第三方驗證、實際註銷與儲存監測結果，並確認公司所稱市場規模與拒絕率的計算口徑。

Next checks should cover first delivery in 2026, third-party verification, actual retirements and storage monitoring, together with the methodology behind the companies' scale and rejection-rate claims.
