API

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

• 连接方式: 电脑或云端
• 传输方式: stdio, Streamable HTTP
• 分类: 其他
• 你需要填写：GREENCALCULUS_API_KEY, Authorization

安装

选择你使用的 AI 应用，然后复制设置。

你需要

• 在云端运行无需安装任何东西，通过互联网连接
• npm已安装 Node.js（用于 npx 命令）

需要你填写的值

• GREENCALCULUS_API_KEY 机密 env
  GreenCalculus API key — free at greencalculus.com/developers. Without one, search_factors and explain_absence still work; the other ten tools are refused.
• Authorization 机密 HTTP header
  Bearer — free at greencalculus.com/developers. Optional: search_factors and explain_absence answer without one.

它能做什么

工具名称和描述与服务器在 2026年11月9日 报告的完全一致。这些内容由作者撰写，不是我们写的；我们以纯文本形式显示。

• lookup_factor

  Look up a single greenhouse-gas emission factor by its canonical key. Returns the value plus an audit envelope: provenance (publisher, exact source reference, retrieval date, LICENCE and whether it may be redistributed, with the attribution the licence requires) and verification

• search_factors

  Find emission factors by section, key prefix, or free text. Returns each match with its key, name, section, VALUE, unit and gas — enough to choose between them or read a few numbers without a second call. For one factor's full audit envelope (publisher, exact source reference, re

• 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 reference, retrieval date, licence, redistribution) and verification. Use this instead of calling lookup_factor in a loop: a portfoli

• 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

• 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

• 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

• calculate_freight

  Freight & logistics emissions (Scope 3 Cat 4 & 9), GLEC framework. THE FACTOR'S DENOMINATOR PICKS THE METHOD — check the factor's unit before choosing the input. Per tonne-km: emissions = tonnes × km × factor, send "mass". Per TEU-km (the sea-container family, e.g. freight_detail

• 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_services.

• 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").

• calculate_cii

  IMO Carbon Intensity Indicator (CII) of a ship and its A-E rating for every year 2023-2030 (MARPOL Annex VI regulation 28; IMO guidelines G1-G5). Give the ship type, its capacity (deadweight for cargo ships, gross tonnage for ro-ro, ro-pax and cruise ships), the distance sailed i

• 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. Returns ranked matches, each carrying the key, value, unit and a confidence score; feed the chosen key to a calculate_* tool or lookup_factor. Prefer

• explain_absence

  Ask why a factor is NOT in the corpus. The reasoned counterpart to coverage: where a country reports zero rows for an inventory family, this says whether that is the world's limit or our backlog. Five classifications: "structural" (no publisher issues this anywhere — stop looking
