概覽

AI 產生的概覽

依據銀行對帳單與活動資料，使用 EPA 排放係數計算組織碳足跡，並產出 HTML 與 Markdown 報告。

可以做什麼: 可讀取銀行 CSV、Xero 或 QBO 匯出檔及結構化活動資料，並協助將交易歸類為電力、燃料、差旅、運輸與廢棄物等可能的排放來源。它使用 EPA 溫室氣體排放係數計算範疇一、範疇二與範疇三排放，在提供營收與員工人數時據此評估碳強度，並產出 HTML 與 Markdown 報告。工具包括 computeEmissions、generateEmissionsReport 與 listEmissionFactors。
適用情境: 適合在準備 ESG 報告、投資盡職調查資料或內部永續檢視時，快速把原始財務匯出與營運輸入轉成排放基準。也適合已有銀行或會計匯出資料、希望避免手動試算表作業並採用 EPA 對齊係數的組織。
執行需求: 以本機 stdio 程序執行，透過 uvx 從 PyPI 套件 carbon-footprint-mcp 安裝（需要 uv；本機開發需要 Python）。未宣告驗證、環境變數或標頭。可搭配 Claude Desktop、Claude Code、Cursor 及其他 MCP 用戶端使用。

安裝前請注意

此伺服器會讀取銀行對帳單與會計匯出等財務資料，即使它聲稱在本機執行、不將財務資料送往外部 API 且預設不儲存資料，仍應先確認要輸入的內容。generateEmissionsReport 會將報告檔案寫入你指定的目錄。排放係數以 EPA 為基礎，電力基準採用 EPA eGRID 區域係數，可能不適用於美國以外的營運。

安裝

README

Carbon Footprint Calculator (MCP Server)

An MCP (Model Context Protocol) server for calculating organizational carbon footprints from bank statements, financial exports, and structured activity data using EPA GHG emission factors.

Privacy and security first

Runs 100% locally on your machine or server

Sends no financial data to external APIs or cloud providers

Stores no data by default

Exposes read-only calculation and reporting tools

Works with Claude Desktop, Cursor, and other MCP clients

Why This Exists

If you are preparing ESG reporting, investor diligence materials, or internal sustainability reviews, getting to a usable emissions baseline is usually slow and manual.

This server helps turn raw bank statements, Xero or QBO exports, and structured operational inputs into a carbon footprint report in minutes. It maps activities to EPA-aligned emission factors and produces both HTML and Markdown outputs.

The user experience is designed to work for organizations in any country, while the current electricity benchmarking still uses EPA eGRID regional factors under the hood.

What It Does

Ingests bank CSVs, Xero or QBO exports, and structured activity data.
Helps categorize transactions into likely emission sources such as electricity, fuel, travel, shipping, and waste.
Computes Scope 1, Scope 2, and Scope 3 emissions using EPA GHG emission factors.
Scores carbon intensity by revenue and headcount when those inputs are provided.
Generates polished HTML and Markdown reports.

Emission Factor Source

All emission factors are based on the EPA GHG Emission Factors Hub (January 2025), including eGRID 2023 electricity factors and IPCC AR5 global warming potentials.

Covered categories include stationary combustion, mobile combustion, electricity, steam or heat, transportation, waste disposal, business travel, employee commuting, and refrigerants.

Installation

Claude Desktop

Install uv.
Open Claude Desktop settings and edit the MCP config.
Add this server:

json

{  "mcpServers": {    "carbon-footprint": {      "command": "uvx",      "args": ["carbon-footprint-mcp"]    }  }}

{  "mcpServers": {    "carbon-footprint": {      "command": "uvx",      "args": ["carbon-footprint-mcp"]    }  }}

Restart Claude Desktop.

Carbon Intensity Scoring

Score	tCO2e per $1M Revenue	Interpretation
Excellent	< 5	Best-in-class for low-footprint operations
Good	5-20	Low intensity
Moderate	20-100	Typical for services and tech
High	100-500	Heavy operations
Very High	> 500	Very high intensity
