Source code Documentation

What can you do with Carbon Footprint Calculator?

  • 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.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package carbon-footprint-mcp
Claude Code 
claude mcp add carbon-footprint-calculator -- uvx carbon-footprint-mcp==1.0.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "carbon-footprint-calculator": {
            "command": "uvx",
            "args": [
                "carbon-footprint-mcp==1.0.0"
            ]
        }

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

  1. Ingests bank CSVs, Xero or QBO exports, and structured activity data.
  2. Helps categorize transactions into likely emission sources such as electricity, fuel, travel, shipping, and waste.
  3. Computes Scope 1, Scope 2, and Scope 3 emissions using EPA GHG emission factors.
  4. Scores carbon intensity by revenue and headcount when those inputs are provided.
  5. 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
  1. Install uv.
  2. Open Claude Desktop settings and edit the MCP config.
