- AlicenseNot gradedqualityCmaintenanceOpen corporate carbon emissions data for AI agents. Search companies and retrieve Scope 1, 2 and 3 disclosure history, Mycelium and Transparency scores, and per-scope figures with reported-vs-estimated provenance on every line.MIT
- AlicenseAqualityBmaintenanceEnables AI agents to query verified-emissions knowledge graphs in natural language and validate data against supported standards, with metered billing and optional verified identity.1672 npmApache 2.0
- FlicenseNot gradedqualityBmaintenanceEnables users to compare air, rail, maritime, and electric ground freight options using GLEC emissions factors, optimize multi-carrier routes, and compute carbon footprints with offset costs. It also generates verified carbon offset credit allocation certificates.7-
- FlicenseNot gradedqualityCmaintenanceWattScope helps teams see the carbon cost of the AI they are already using. Ask Claude to record a piece of work and it attributes the estimated footprint to your organization and to a project, then reports it back — per session, per project, or organization-wide. Every figure is an estimate, and carries the strength of the evidence behind it.-
- FlicenseAqualityDmaintenanceEstimates the environmental footprint of your AI use — energy (kWh), miles driven, water used for cooling, and CO₂ — plus a prompt-efficiency score, working with any AI client by measuring token usage.9-
- FlicenseNot gradedqualityBmaintenanceEnables users to compare and select multi-carrier freight routes by applying GLEC emissions factors across air, rail, maritime, and electric ground modes while weighing transit time and landed cost. It also calculates the resulting CO2 footprint and generates verified carbon offset credit allocation certificates for the chosen route.7-

Scored across 12 tools
The find/lookup tools are mostly separable: search_factors and resolve_factor both find factors but one is structured search and the other natural-language best-key; lookup_factor/lookup_factors differ by batch. The calculate_* tools are cleanly distinguished by method/scope, though calculate_activity is generic enough to overlap conceptually with the sector-specific calculators.
Every tool follows a consistent verb_noun snake_case pattern: search_factors, lookup_factor(s), resolve_factor, explain_absence, and calculate_<domain>. Pluralization is used deliberately for batch lookup. No mixed conventions or vague verbs.
Twelve tools is well within the sweet spot for a domain server. Each tool earns its place: three discovery/lookup tools, one absence explainer, one resolver, and seven calculation methods. The count reflects the breadth of GHG calculation methods without redundant duplicates.
The server covers the full read/lookup/calculate lifecycle for emission factors: discovery, resolution, provenance audit, absence explanation, and multiple calculation methods. Minor gaps exist (no dedicated employee-commuting/waste calculators, no factor management), but generic calculate_activity and broad factor search mitigate them.
