GM新永續長上任，循環經濟與碳中和目標將迎轉折關鍵

通用汽車（GM）在氣候與永續轉型的關鍵路口，迎來新任永續長（Chief Sustainability Officer, CSO）——來自科技與製造業跨界背景的Garber。她接替去年10月退休的Kristen Siemen，肩負起引領GM邁向零排放與循環經濟未來的任務。

GM Names New Chief Sustainability Officer as Company Navigates Climate and Sustainability Transition

At a pivotal juncture in its climate and sustainability transformation, General Motors (GM) has appointed a new Chief Sustainability Officer (CSO) - Garber, a cross-industry veteran with experience spanning tech and manufacturing. She succeeds Kristen Siemen, who retired in October 2023, and now bears the responsibility of steering GM toward a zero-emissions and circular economy future.

Garber的到來，並非只是企業人事更迭。她的履歷，幾乎可說是一張「美國企業永續發展縮影地圖」：從醫療供應鏈巨頭McKesson，到材料科技企業3M，再到全球飲料品牌可口可樂，最後進入資訊科技領域，在Dell帶領全球永續策略與社會創新計畫。如今，她將這些累積帶入汽車產業最具代表性的企業之一——GM。

Garber’s arrival marks more than just a leadership transition. Her resume could be seen as a “map” of corporate sustainability in the U.S.: from the healthcare supply chain giant McKesson, to materials science leader 3M, global beverage brand Coca-Cola, and most recently, Dell, where she led global sustainability strategy and social innovation. Now, she brings this wealth of experience to one of the most iconic companies in the automotive industry - GM.

Garber在接任後於LinkedIn上表示，她期望在新角色中「加速邁向零排放未來，並推動降低成本與物料浪費的循環經濟方案」。在GM逐步推進電動車轉型、並積極導入再生能源的當下，這位新永續長不僅是目標的執行者，也將成為策略的整合者。

Following her appointment, Garber shared on LinkedIn that she hopes to “accelerate progress toward a zero-emissions future and drive circular economy solutions that reduce costs and material waste.” As GM continues its electric vehicle transition and ramps up renewable energy integration, Garber is poised not only to execute sustainability targets but also to integrate them into broader strategic decisions.

延續Siemen的碳中和藍圖

Garber接下的是一份規模龐大的永續藍圖。由Siemen任內所定下的系列目標，包括：

這不只是碳管理目標，更是一場牽動供應鏈、製造、設計與消費行為的全面性變革。Siemen任內建立了明確的路徑，Garber的挑戰，則是在快速變動的政策與技術格局中，讓這張藍圖成為現實。

汽車產業的新永續敘事者

Garber的特質，或許正是GM當前最需要的。汽車產業正面臨多重挑戰——歐洲與美國對內燃機車的退場期程、鋰與關鍵礦產的供應風險、ESG資訊揭露趨嚴，還有全球消費者對品牌責任的重新審視。在這樣的時刻，一位熟悉跨界永續策略、了解供應鏈複雜性，又擅長社會溝通的領導者，格外關鍵。

Carrying Forward Siemen’s Carbon Neutrality Blueprint

Garber inherits an ambitious sustainability roadmap laid out under Siemen’s tenure, which includes:

These are more than just carbon management targets - they represent a systemic transformation that touches every part of GM’s value chain, from supply chains and manufacturing to product design and consumer behavior. While Siemen mapped out the path, Garber’s challenge is to bring this vision to life amid a rapidly evolving policy and technology landscape.

A New Sustainability Storyteller for the Auto Industry

Garber may be exactly the kind of leader GM needs now. The automotive sector is facing a perfect storm of challenges: phase-out deadlines for internal combustion engine vehicles in Europe and the U.S., critical mineral supply risks, increasingly stringent ESG disclosure requirements, and growing consumer expectations around corporate accountability. At this moment, a leader who understands cross-sector sustainability strategy, supply chain complexity, and effective public communication is more essential than ever.

她的背景也預示著GM可能將永續視為更深層的轉型驅動力，而非僅止於碳排查表上的數據。過去在可口可樂與Dell的經驗，讓Garber深知「永續」不只是環保，更是品牌敘事、風險管理與價值創造的綜合操作。

循環經濟，不只是成本控制

Her background also signals a shift in how GM might position sustainability - not merely as a compliance measure or carbon tracking exercise, but as a core driver of transformation. Garber’s experience at Coca-Cola and Dell has shown her that “sustainability” is not just about environmental impact - it’s also about brand narrative, risk management, and long-term value creation.

Circular Economy: Beyond Cost-Saving

特別值得注意的是，Garber點出循環經濟將是GM下一階段的重要路徑。這意味著，從電動車電池回收、製造過程減廢，到材料再利用策略，GM可能將從供應鏈源頭設計出更少浪費、更多回收的產品生命週期。

Garber’s emphasis on the circular economy is particularly noteworthy. This suggests GM may double down on initiatives like EV battery recycling, waste reduction in manufacturing, and materials reuse. Designing products with waste minimization and resource recovery in mind could become central to GM’s approach.

在全球資源壓力日增、碳邊境調整機制（CBAM）等政策逐漸落地的背景下，這不只是永續形象的工程，更是實質競爭力的根本。Garber將如何在這條路上整合策略、引導投資與溝通進展，將成為GM能否在新一輪汽車產業洗牌中穩住腳步的關鍵。

Amid mounting global resource pressures and the rollout of policies like the Carbon Border Adjustment Mechanism (CBAM), circularity is not just about optics - it’s increasingly tied to competitive advantage. How Garber aligns strategy, directs investment, and communicates progress will play a critical role in determining whether GM can maintain its footing in the next phase of industry disruption.

在此同時，外界也在觀察：這位曾服務於多家《財富》500大企業的資深永續領導者，是否能讓GM成為跨產業的氣候創新示範場。畢竟，當汽車不再只是移動工具，而是能源使用與碳足跡的縮影，誰能說清楚「永續」的故事，就有可能主導下一個世代的車壇競賽。

Meanwhile, observers are watching closely to see whether this veteran sustainability leader - who has served at several Fortune 500 companies - can turn GM into a cross-sector model for climate innovation. After all, as vehicles become more than just modes of transportation - and instead reflections of energy usage and carbon footprints - whoever can best tell the story of sustainability may well win the next chapter of the automotive race.
