FASB Topic 818：企業碳權資產與會計的挑戰與未來

當淨零轉型的浪潮席捲全球，碳權與各類環境信用（environmental credits）逐漸成為企業資產負債表上不可忽視的存在。然而，這些氣候金融工具該如何在會計上被記錄、揭露與管理，一直是美國會計準則的空白地帶。如今，美國財務會計準則委員會（FASB）針對環境信用的會計處理所提出的「Topic 818」草案，正試圖填補這一制度缺口，但其影響卻遠不僅止於會計技術——更關乎企業是否還願意為氣候承諾買單。

A New Order in Carbon Accounting: How FASB is Reshaping the Financial Language of Corporate Carbon Credits and Sustainability Commitments

As the global transition to net-zero accelerates, carbon credits and various environmental credits are increasingly becoming significant items on corporate balance sheets. However, how these climate finance tools should be recorded, disclosed, and managed in accounting has long been a blind spot in U.S. accounting standards. Now, the U.S. Financial Accounting Standards Board (FASB) is proposing a new standard for environmental credits through Topic 818, attempting to fill this gap. However, its impact goes beyond technical accounting - it also concerns whether corporations will continue to back their climate commitments with real investments.

明確化的規則，仍藏隱憂

FASB 此次針對環境信用的會計準則草案，首度將碳排放配額（例如碳交易市場中的 cap-and-trade）、燃油經濟信用（CAFE credits）、再生能源證書（RECs）與可再生識別碼（RINs）等氣候金融工具納入統一規範，補足美國通用會計準則（GAAP）長期以來的空白。對許多企業與審計機構而言，這是一個重大進展。

Clarified Rules, Yet Hidden Concerns

FASB’s proposed standard on accounting for environmental credits is the first to incorporate climate financial instruments such as carbon emission allowances (e.g., those from cap-and-trade markets), fuel economy credits (CAFE credits), renewable energy certificates (RECs), and renewable identification numbers (RINs) under a unified framework, closing a long-standing gap in Generally Accepted Accounting Principles (GAAP). For many businesses and audit firms, this marks a significant step forward.

環境保護基金會（Environmental Defense Fund, EDF）便在意見函中表示肯定，認為這項提案「提供了業界迫切需要的明確性與一致性，有助於改善永續揭露品質與財報透明度」。包括福特汽車（Ford）與通用汽車（GM）等企業也在意見期間表達支持，顯示此舉有助企業對其氣候工具進行更有效的財務管理。

但「立即費損」可能誤殺碳市生機？

儘管方向正確，EDF 也對部分細節表示擔憂。依照草案規定，若企業基於自願性氣候承諾購買碳權，應立即將成本列為費用，而非視為未來資產。EDF 指出，這樣的作法不但會導致企業財報短期內出現虛高費用，也可能無意間削弱企業參與氣候項目的誘因，進而影響環境信用市場的經濟基礎。

The Environmental Defense Fund (EDF), in its comments, expressed support, stating that the proposal “provides the industry with much-needed clarity and consistency, which will help improve the quality of sustainability disclosures and financial reporting transparency.” Companies such as Ford and General Motors have also voiced support, signaling that this move will enable businesses to more effectively manage their climate tools from a financial standpoint.

But Does “Immediate Expense Recognition” Risk Killing Carbon Markets?

EDF 建議，應允許企業將這類交易視為「非可退還押金」（non-refundable deposits），待碳權交付後再列為無形資產。如此不僅可與國際財務報導準則（IFRS）接軌，更能在資產負債表上真實呈現企業對未來永續承諾的主動投資，而非被動支出。

EDF 法律顧問 Holly Pearen 更警告：「若未妥善處理，立即費損的作法將造成行為與經濟上的不利後果，抑制企業對高品質碳權項目的支持，反而削弱氣候治理目標。」

誰來界定「環境信用」的真實性？

不只有會計處理方式存疑，「什麼算是有效的環境信用」也成為爭議焦點。另一家環境倡議團體「環境責任中心」（Center for Environmental Accountability, CEA）便呼籲，FASB 不應輕率將所有環境信用一體視為資產。

Despite the positive direction, EDF raised concerns about certain details. According to the proposal, if companies purchase carbon credits based on voluntary climate commitments, they should immediately expense the cost rather than treat it as a future asset. EDF argues that this approach would not only lead to inflated short-term expenses in financial statements but could inadvertently weaken the incentives for businesses to engage in climate projects, thereby undermining the economic foundation of the environmental credit market.

EDF recommends allowing companies to treat such transactions as "non-refundable deposits" and classify them as intangible assets once the carbon credits are delivered. This would align with International Financial Reporting Standards (IFRS) and better reflect businesses' proactive investments in future sustainability commitments rather than passive expenses on their balance sheets.

EDF Legal Advisor Holly Pearen further warned, "If mishandled, immediate expense recognition could result in harmful behavioral and economic consequences, suppressing corporate support for high-quality carbon credit projects and ultimately weakening climate governance goals."

Who Defines the Authenticity of Environmental Credits?

The controversy doesn't just lie in the accounting treatment; it also extends to the question of what qualifies as valid environmental credit. Another environmental advocacy group, the Center for Environmental Accountability (CEA), has called for caution, urging FASB not to categorize all environmental credits as assets.

「除非該信用是由聯邦或州政府立法建立的強制性市場機制所產生，如 cap-and-trade，否則其背後的環境屬性往往難以衡量，甚至可能存在誤導性宣稱的風險，接近綠色詐欺（green fraud）。」CEA 主席 Marc Marie 在意見函中寫道。

他亦提醒，鑑於前總統川普時期美國退出《巴黎協定》與弱化氣候監管的前例，FASB 在制定會計定義與適用範圍時，必須審慎思考其政策後果，避免讓不具法律強制力的碳信用「冒名頂替」，獲得不當資產認定。

企業擔憂：資訊揭露會不會傷害競爭力？

除了環團的觀點，企業的顧慮也不容忽視。例如福特汽車在回函中便指出，部分揭露要求可能牽涉到「競爭性敏感資訊」，而草案對於負債評估不允許納入未來「減緩行動」（mitigating actions），也可能導致收益表出現不必要的波動，影響財務穩定性。

“Unless the credit comes from a mandatory market mechanism established by federal or state legislation, such as cap-and-trade, the environmental attributes behind these credits are often hard to measure and could even be misleading, potentially bordering on greenwashing,” wrote CEA President Marc Marie in his comments.

He also cautioned that, given the U.S. withdrawal from the Paris Agreement and the weakening of climate regulations during the Trump administration, FASB must consider the policy implications of its definitions and scope to avoid improperly recognizing non-legally binding carbon credits as legitimate assets.

Corporate Concerns: Will Information Disclosure Hurt Competitiveness?

In addition to environmental groups’ concerns, businesses' perspectives cannot be overlooked. For instance, Ford Motor Company, in its response, pointed out that certain disclosure requirements could involve "competitively sensitive information". The proposal’s stance on liability assessment, which does not allow for the inclusion of future "mitigating actions", could also result in unnecessary volatility in earnings statements, affecting financial stability.

Topic 818：制度進化還是市場干擾？

FASB 自 2022 年將環境信用議題列為高優先技術議題以來，便備受關注。此次提出的 Topic 818 草案試圖為碳市場與企業財報之間建立橋梁，但從目前來看，它可能也無意間創造出一個新的權衡困境：如何在會計清晰、資產真實與市場誘因三者間找到平衡點？

Topic 818: Institutional Evolution or Market Disruption?

Since 2022, FASB has prioritized the issue of environmental credits as a high technical priority. The introduction of Topic 818 aims to bridge the gap between the carbon market and corporate financial reporting. However, it may inadvertently create a new dilemma: How to balance clarity in accounting, the authenticity of assets, and market incentives?

隨著公眾諮詢結束，FASB 將於後續會議中彙整意見並決定下一步方向。對企業而言，這場會計改革不只是記帳方式的改變，更是一場對氣候承諾「能不能被資產化」的本質辯論。

With public consultations now closed, FASB will review feedback and decide on the next steps. For businesses, this accounting reform represents not just a change in bookkeeping methods but also a fundamental debate over whether climate commitments can be capitalized as assets.

若企業的永續投資被視為成本，而非資產，那麼在現實資本市場的語境中，它將如何說服投資人、董事會與市場相信「長期氣候承諾是值得的」？Topic 818 也許正在回答這個比會計還複雜的問題。

If a company’s sustainability investments are treated as costs rather than assets, how can they convince investors, boards, and the market that long-term climate commitments are worth the investment? Topic 818 may ultimately answer this more complex question than it does the accounting one.
