Taiwan Carbon Open Data (Unofficial)

Calculate several activities and arrange the results as a greenhouse gas inventory: grouped into Scope 1 (direct), Scope 2 (purchased energy) and Scope 3 (other indirect), with a subtotal per scope, Scope 1 by gas, and a Scope 1+2 total. Subtotals and totals are withheld, with the reason, when items mix CO2 and CO2e, when an item could not be calculated, or when Scope 3 holds product carbon footprints that may overlap Scopes 1 and 2. The scope assignment is this service's default by factor type and can be overridden per item. Covers only the activities supplied; it is not a complete or verified inventory. 計算多筆活動並整理成溫室氣體盤查清冊的形式：分為範疇一（直接排放）、範疇二（能源間接）、範疇三（其他間接），提供各範疇小計、範疇一依氣體分列，以及範疇一加二的合計。項目混用 CO2 與 CO2e、有項目算不出來、或範疇三含可能與範疇一、二重疊的產品碳足跡時，不提供對應的小計或合計並說明原因。範疇分類是本服務依係數類型的預設，可逐筆覆寫。只涵蓋你提供的活動，不是完整或經查證的盤查。

Calculate several activities at once, each with its own factor and source. A total is given only when every item succeeded and the items share a gas basis and boundary type; otherwise the reason is stated. 批次計算多筆活動，逐筆回傳結果與來源。只有全部成功、氣體基礎與邊界類型一致時才提供合計，否則說明不提供的原因。

Calculate emissions for one activity: activity data × an official factor from the database. Checks units, the applicable year and whether the factor may be used for calculation, and returns the formula, kg and tonnes, the factor version and the source URL. Returns a clear error instead of guessing when the unit is incompatible, the year does not match or required data is missing (fuel factors need a user-supplied lower heating value; refrigerants need the basis of the quantity). A refrigerant blend such as R-410A can be calculated by passing refrigerant_blend with the user-supplied composition instead of factor_id. 計算單一活動的排放量：活動數據 × 資料庫中的官方係數。會檢查單位、適用年度與係數是否可用於計算，回傳公式、公斤與公噸、係數版本與來源網址。單位不相容、年度不符或缺少必要資料時（燃料係數需要使用者提供低位熱值，冷媒需要說明數量的依據）回傳明確錯誤，不會猜測。混合冷媒（如 R-410A）可不給 factor_id，改以 refrigerant_blend 提供使用者確認過的成分比例。

Show the sync status of each official source: when it was last checked, whether the data may be stale, and whether a difference from the official data is waiting for review. Read-only; it cannot trigger a sync or write anything. 查看各官方來源的同步狀態：最近檢查時間、資料是否可能過期、是否有與官方資料不一致而待審核的項目。唯讀，不能觸發同步或寫入。

Compare two calculations (for example two years). Separates the effect of changed activity data from the effect of a changed factor, and flags when the calculation method differs so the difference is not read as an actual reduction. 比較兩筆計算（例如不同年度）。區分活動量改變與排放係數改變的影響；計算方法不同時會標示，避免把差異誤讀為實際減碳成效。

Get Taiwan's official electricity emission factor (kgCO2e/kWh) for a given year, published by the Energy Administration. From the 2025 factor year there are three values by usage; earlier years have one. Never substitutes another year: if the year is missing it says so and lists the years available. 查詢經濟部能源署公布的指定年度電力排碳係數（公斤CO2e/度）。114 年度（2025）起依用途有三個數值，之前每年一個。不會以其他年度代替：該年度沒有資料時會明說並列出可用年度。

Get one factor in full by ID: the original government record, unit, applicable year, boundary, official source, version, whether it can be used for calculation directly, and usage limits. Find the ID with search_emission_factors first. 依係數 ID 取得完整資訊：官方原始紀錄、單位、適用年度、計算邊界、官方來源、版本、是否可直接計算與使用限制。請先用 search_emission_factors 找到 ID。

Explain the calculation methods, scope, data limits and official references. Read this before interpreting results or combining different kinds of factors. 說明計算方法、適用範圍、資料限制與官方依據。解讀結果或合併不同類型的係數之前請先閱讀。

List the official Taiwan government sources behind this service, with dataset codes, URLs, licence, sync status and how many factors each holds. 列出本服務整合的官方資料來源：資料集代碼、網址、授權、同步狀態與係數數量。

List every recorded version of one factor, newest first. Old versions are kept so past calculations can be reproduced. 列出指定係數的所有歷史版本（新的在前）。舊版本會保留，讓過去的計算可以重現。

Map an activity or ledger-account description (for example an electricity bill, fleet fuel, or a plastic resin purchase) plus an optional unit to candidate official factors. Returns candidates with unit compatibility, applicability conditions and the questions the user must answer; it never picks one. Use this when the user's wording is not an official factor name, then confirm with the user before calling calculate_emissions. The term mapping is curated by this service, not official. 把活動或會計科目的描述（例如電費、公務車加油、塑膠原料採購）與單位對到候選的官方係數，回傳每筆的單位相容性、適用條件與需要使用者回答的問題；不會代為選定。使用者的說法不是官方係數名稱時用這個工具，並在呼叫 calculate_emissions 之前先向使用者確認。用詞對照是本服務整理的，不是官方資料。

Check that the service is up. Returns status, service name, version and server time. 確認服務狀態，回傳狀態、服務名稱、版本與伺服器時間。

Search official Taiwan emission factors by keyword, category, type, year or unit. Returns factor IDs to pass to get_emission_factor and calculate_emissions. Covers electricity, tap water and fuel combustion; returns an explicit not-found message rather than a near match. 以關鍵字、類別、類型、年度或單位搜尋台灣官方排放係數，回傳的係數 ID 可交給 get_emission_factor 與 calculate_emissions。目前收錄電力、自來水與燃料燃燒；查不到會明確說明，不會給相近的替代品。
