Known tools 12

lookup_factor

Look up a single greenhouse-gas emission factor by its canonical key.

Inferred read-only

search_factors

Find emission factors by section, key prefix, or free text.

Inferred read-only

lookup_factors

Look up SEVERAL emission factors by key in one call, each with the same audit envelope lookup_factor returns — provenance (publisher, exact source cell, retrieval date, licence, redistribution) and verification.

Inferred read-only

calculate_activity

Turn activity data into greenhouse-gas emissions: emissions = activity × factor.

Inferred read-only

calculate_embodied

Whole-life embodied carbon for materials, per EN 15978.

Inferred read-only

calculate_pcaf

Compute PCAF Part A financed emissions for a portfolio.

Inferred read-only

calculate_electricity

GHG Protocol Scope 2 for purchased electricity, both methods.

Inferred read-only

calculate_freight

Freight & logistics emissions (Scope 3 Cat 4 & 9), GLEC tonne-km method: emissions = tonnes × km × factor.

Inferred read-only

calculate_spend

Spend-based (EEIO) Scope 3 screening: emissions = spend × economic-intensity factor.

Inferred read-only

calculate_business_travel

Business travel emissions (Scope 3 Cat 6), distance method: emissions = km × passengers × factor.

Inferred read-only

resolve_factor

Find the best emission-factor key(s) for a plain-language description — the hardest step is picking the right key out of ~16,000.

Inferred read-only

explain_absence

Ask why a factor is NOT in the corpus.

Inferred read-only
