微軟擴大碳移除，打造負碳樣板

當全球科技巨頭紛紛搶進淨零市場，微軟（Microsoft）再次展現其氣候治理上的領先企圖。近日，微軟宣布擴大與瑞典斯德哥爾摩能源公司（Stockholm Exergi）的合作，將原本 330 萬噸的碳移除承諾，一舉提高至 508 萬噸，成為目前全球年交付規模最大的生質碳捕捉協議。這項舉動，不僅是對碳移除技術的信任投票，更反映出微軟試圖透過**高耐久碳移除（high-durability CDR）**技術塑造「碳負未來」的戰略佈局。

Microsoft’s Carbon Negative Ambition: Building a Global Blueprint for High-Durability Carbon Removal - Starting from Stockholm

As global tech giants race to position themselves in the net-zero economy, Microsoft has once again demonstrated its leadership in climate governance. The company recently announced an expanded partnership with Stockholm Exergi, increasing its carbon removal commitment from 3.3 million tons to a striking 5.08 million tons. This makes it the largest biomass carbon capture agreement in the world by annual delivery volume, and signals Microsoft's strategic push toward a “carbon negative future” through high-durability carbon removal (CDR) technologies.

這場合作的核心，是正在斯德哥爾摩建設中的 BECCS（生質能碳捕捉與封存）設施。預計 2028 年完工，這座價值 13 億美元的設施每年將可捕捉高達 80 萬噸的生物源 CO₂，封存量甚至超過整個斯德哥爾摩市道路交通的碳排放。

At the center of this deal is the BECCS (Bioenergy with Carbon Capture and Storage) facility currently under construction in Stockholm. Scheduled for completion in 2028, the $1.3 billion plant will be capable of capturing up to 800,000 tons of biogenic CO₂ per year - more than the total emissions from all road traffic in Stockholm during the same period.

捕捉後的 CO₂ 將由「Northern Lights」計畫協助跨境運輸至挪威北海，進行深層地質封存。這項由 Equinor、Shell 與 TotalEnergies 聯手推動的碳運儲聯盟，也正逐步成為歐洲碳捕捉基礎設施的關鍵樞紐。

Captured CO₂ will be transported across borders through the Northern Lights initiative and permanently sequestered beneath the North Sea. This carbon transport and storage alliance - led by Equinor, Shell, and TotalEnergies - is fast becoming a key pillar of Europe’s emerging carbon capture infrastructure.

為何這個協議值得關注？

首先，它證明企業願意為高品質的碳移除付出真金白銀。在眾多碳補償計畫仍存在「綠色漂綠」爭議的當下，微軟選擇支持耐久性封存、且具備監測與可追蹤性的 BECCS 路線，對市場釋出強烈訊號：高品質碳移除正成為企業減碳策略的核心組成，而不再只是「碳中和」的行銷話術。

其次，微軟此舉也體現其作為「市場建構者」的角色。與 Stockholm Exergi 的合作並非孤例，微軟僅在過去一個月，就與包括 Carba（生物炭）、Living Carbon（碳匯森林）、Fidelis、AtmosClear、CO280（針對紙漿與造紙業）等多家氣候新創達成碳移除協議，總量超過 800 萬噸。

“This isn’t just a carbon removal transaction - it’s the foundation of an entire climate governance industry,” said Anders Egelrud, CEO of Stockholm Exergi.

Why Is This Deal Worth Watching?

First, it demonstrates that corporations are willing to pay for high-quality carbon removal. At a time when many carbon offset programs are facing greenwashing scrutiny, Microsoft’s investment in BECCS - an approach offering durability, traceability, and third-party verification - sends a powerful signal: high-integrity carbon removal is becoming central to corporate decarbonization strategies, no longer a branding afterthought.

這不僅是購買碳移除，更是為整個碳移除供應鏈創造需求信心與商業規模。

微軟的下一步，是市場的下一步？

Second, Microsoft’s move highlights its growing role as a market builder. The Stockholm Exergi agreement is part of a broader portfolio. In the past month alone, Microsoft has signed CDR contracts with Carba (biochar), Living Carbon (forest carbon sinks), Fidelis, AtmosClear, and CO280 (focused on the pulp and paper industry), with total removals exceeding 8 million tons.

These aren’t just carbon purchases - they are strategic investments meant to scale the entire carbon removal ecosystem by creating market demand and commercial viability.

Microsoft’s Next Step, the Market’s Next Chapter?

根據微軟的承諾，其將在 2030 年達成「碳負排」目標（碳移除量大於自家排放量），更在 2050 年實現歷史排放總移除。這意味著，碳移除對微軟來說，已不是抵消手段，而是一種責任清算與商業前瞻。

Microsoft has pledged to become carbon negative by 2030, and to remove all of its historical emissions by 2050. For the company, carbon removal is no longer just an offset - it’s a responsibility ledger and a forward-looking business model.

From a policy perspective, this transnational agreement also raises key questions for the future of global carbon markets and regulatory frameworks:

而從政策角度來看，這場跨國合作亦為未來的國際碳市場與監理框架提出挑戰與想像：如何確保碳移除的透明性、準確性與持久性？碳定價如何反映其真實成本與環境價值？

How can we ensure transparency, accuracy, and durability in carbon removals? How should carbon pricing reflect the true environmental and technological cost?

當氣候危機不再只是「減少排放」，而是「負碳經濟」的啟動，微軟的佈局無疑為企業氣候策略樹立了標竿。

As climate action shifts from “emission reduction” to “net-negative strategies,” Microsoft’s approach sets a clear benchmark for the corporate sector.
