加州放寬首年企業氣候申報，既有數據與未確信資料可先行提交

CARB 表示首批範疇 1 與範疇 2 報告預計於 2026 年 11 月 10 日提交。 首年可提交最近一個已完成會計年度的既有資料，未蒐集資料者可說明，且受理不限定單一排放係數資料集或格式。

CARB says the first Scope 1 and Scope 2 reports are expected by 10 November 2026. Companies may use data from a recently completed fiscal year, explain non-collection, and submit in varied formats without a prescribed emissions-factor dataset in the first year.

CARB 表示首批範疇 1 與範疇 2 報告預計於 2026 年 11 月 10 日提交。；首年可提交最近一個已完成會計年度的既有資料，未蒐集資料者可說明，且受理不限定單一排放係數資料集或格式。；有限確信報告在 2026 年不是文件受理條件，後續年度的方法、格式、時程與確信要求將持續制定。

CARB says the first Scope 1 and Scope 2 reports are expected by 10 November 2026. Companies may use data from a recently completed fiscal year, explain non-collection, and submit in varied formats without a prescribed emissions-factor dataset in the first year. Limited assurance is not an acceptance condition in 2026, while later methodology, format, timing and assurance rules remain under development.

彈性安排可能讓不同會計年度、組織邊界、排放係數與估算方法進入同一公開資料池，降低橫向可比性。企業若把受理等同合規品質，也可能掩蓋數據缺口與未確信風險。

Flexibility may put different fiscal years, organisational boundaries, factors and estimation methods into one public pool, weakening comparability. Treating acceptance as proof of quality could hide data gaps and unassured risk.

企業應保留實體清單、邊界決策、活動數據、係數版本、估算、調整與簽核，並在報告中清楚揭露資料年度、涵蓋率、確信狀態與後續補正計畫。

Companies should retain entity lists, boundary decisions, activity data, factor versions, estimates, adjustments and approvals, while disclosing data year, coverage, assurance status and planned remediation.

首年寬限可讓申報平台和企業控制環境逐步就緒，但結果將是一個過渡期資料集。監管者與投資人需要把「已提交」和「可比較、可確信」分開。

Relief allows reporting systems and company controls to mature, but creates a transitional dataset. Regulators and investors must distinguish filed from comparable and assured.

加州規則影響跨州與跨國企業，也會透過客戶要求傳導到供應鏈。首年格式自由度提高了資料交換需求，特別是法人、設施和期間識別的一致性。

California rules reach interstate and multinational companies and will cascade through customer requests. Flexible first-year formats increase the need for consistent entity, facility and period identifiers in data exchange.

SNN 編輯分析：台灣上市櫃公司與美國客戶供應鏈可能直接或間接受到加州申報牽動。揭露前證據基礎設施應建立法人到工廠的主檔、盤查邊界版本、能源帳單與設備量測、排放係數來源與生效日、估算理由、缺漏清單、內控簽核和確信調整，並把加州申報、台灣永續揭露與客戶問卷映射到同一底層證據。首年寬限最適合用來補齊控制環境，而不是延後建檔；否則 2027 年確信要求提高時，企業將無法解釋年度差異。此段為編輯解讀，不是來源已驗證事實。

SNN editorial analysis: Taiwan-listed companies and suppliers to US customers may be directly or indirectly affected by California reporting. Pre-Disclosure Evidence Infrastructure should maintain legal-entity-to-facility masters, boundary versions, utility bills and equipment measurements, factor sources and effective dates, estimation rationale, gap lists, internal approvals and assurance adjustments. California filings, Taiwan sustainability disclosure and customer questionnaires should map to the same underlying evidence. The first-year relief is best used to complete this control environment, not to postpone records. Otherwise a company may be unable to explain year-on-year differences when assurance expectations rise in 2027. This is editorial interpretation, not a source-verified fact.

後續需追蹤 CARB 最終規則、平台欄位、範疇 3 時程、確信層級與訴訟結果。

Next review should track CARB final rules, platform fields, Scope 3 timing, assurance levels and litigation outcomes.
