What's in it

Data offered docs-verified: Scope 1/2/3 GHG calculation · versioned, source-cited emission factor catalog · unit conversion between units of the same physical dimension · AR5/AR6 GWP set selection · scope 2 location-based and market-based totals · biogenic carbon disclosed separately from the scope totals
Coverage llm-inferred: Global
Formats docs-verified: MCP stdio · MCP streamable HTTP
Access docs-verified: Free and open source under the MIT licence; no authentication configured (ENTRY auth: null). Requires the .NET 10 runtime. Emission factor data carries its publisher's licence.

Useful for

Use cases llm-inferred: Scope 1/2/3 inventory built from site activity data for a client's carbon footprint · Scope 2 location-based versus market-based electricity emissions for an ESG or disclosure report · Checking draft carbon figures for disclosure gaps before submission · Stating which AR5 or AR6 GWP set underpins a published footprint figure
Audience llm-inferred: environmental consultants · sustainability and ESG reporting analysts · carbon accountants · developers integrating GHG accounting into ERP systems or batch jobs

Limitations

Constraints docs-verified: Pre-release package: install requires the --prerelease flag · Requires the .NET 10 runtime, including Microsoft.AspNetCore.App · Claude Desktop: hand-editing claude_desktop_config.json no longer works; install as an extension using an absolute path to the binary · Container image serves the HTTP transport only; stdio is not available · Legacy SSE transport is deliberately not provided · Figures derived from an unverified factor set are not treated as disclosures · Scope 2 totals require choosing one method; requesting a method no line reports is an error
