Что умеет
- Lookup Factor: Look up a single greenhouse-gas emission factor by its canonical key and get the value with full provenance (source id, exact source cell, data version). Use search_factors first if you
- Search Factors: Find emission-factor keys by section, key prefix, or free text. Returns matching keys, names, and sections (values are redacted here — call lookup_factor for the value).
- Calculate Activity: Turn activity data into greenhouse-gas emissions: emissions = activity × factor. Give an amount + unit and a factor key; the unit engine converts to the factor basis (MWh→kWh, tonn

Look up greenhouse-gas emission factors and run standards-based carbon calculations (activity-based, embodied EN 15978, PCAF financed emissions) — every result returns with its exact source cell and data version, so your agent hands back sourced, citable numbers instead of a guess. 13,000+ factors across 50+ categories (grid, fuels, freight, refrigerants, AFOLU, CBAM, construction materials, spend-based EEIO, digital). Free tier, no card.
Список инструментов сервера (10)
Технические названия из tools/list. Нужны только разработчикам.
| lookup_factor | Look up a single greenhouse-gas emission factor by its canonical key and get the value with full provenance (source id, exact source cell, data version). Use search_factors first if you do not know the key. |
| search_factors | Find emission-factor keys by section, key prefix, or free text. Returns matching keys, names, and sections (values are redacted here — call lookup_factor for the value). |
| calculate_activity | Turn activity data into greenhouse-gas emissions: emissions = activity × factor. Give an amount + unit and a factor key; the unit engine converts to the factor basis (MWh→kWh, tonne→kg, gallon→litre, mile→km) and returns the emissions with the working, the GHG Protocol scope, and the source. Use search_factors / lookup_factor to find the factor key. |
| calculate_embodied | Whole-life embodied carbon for materials, per EN 15978. Give a material key + quantity (+ optional boundary A1-A3 / A1-A4 / A1-A5 / A1-C); it assembles the declared lifecycle modules (A1-A3, B, C1-C4, D) into stages, totals the boundary, reports module D separately, and flags any missing stage as not-assessed (never zero). Find material keys via search_factors (section "materials"). |
| calculate_pcaf | Compute PCAF Part A financed emissions for a portfolio. Returns each holding's attribution factor and financed emissions, the portfolio total, the outstanding-weighted data-quality score, and the audit trail (formula + PCAF source). |
| calculate_electricity | GHG Protocol Scope 2 for purchased electricity, both methods. Always returns location-based (grid-average) emissions; also returns market-based when you supply a contractual supplier_factor (e.g. a green tariff / REC = 0) or a market_factor_key (residual mix). Find grid keys via search_factors (section "grid"). |
| calculate_freight | Freight & logistics emissions (Scope 3 Cat 4 & 9), GLEC tonne-km method: emissions = tonnes × km × factor. Find mode factors via search_factors (section "freight" or "freight_detailed"), e.g. freight.road_hgv.tonne_km. |
| calculate_spend | Spend-based (EEIO) Scope 3 screening: emissions = spend × economic-intensity factor. Spend must be in the factor's own currency/year (no FX). Find sector factors via search_factors (section "spend_based"), e.g. spend_based.us.naics6.541511.custom_computer_programming. |
| calculate_business_travel | Business travel emissions (Scope 3 Cat 6), distance method: emissions = km × passengers × factor. Air factors come in with_rf / without_rf (radiative forcing) variants. Find factors via search_factors (section "business_travel"). |
| resolve_factor | Find the best emission-factor key(s) for a plain-language description — the hardest step is picking the right key out of ~13,000. Returns ranked candidates with a confidence score; feed the chosen key to a calculate_* tool or lookup_factor. Prefer this over guessing a key. |
