GHG Protocol detailed guide. An agent skill from revfactory/harness-100.

  • Carbon emissions
  • SKILL.md covers Scope 1/2/3 Classification…, Emission Calculation Formulas, Reporting Framework Alignment and Data Quality Ratings, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Carbon footprint requests

What it does

Ghg Protocol is an agent skill from revfactory/harness-100. GHG Protocol detailed guide. Referenced by the environmental-analyst agent when calculating and reporting greenhouse gas emissions. Use for 'GHG Protocol', 'carbon emissions', 'Scope 1/2/3', or 'carbon footprint' requests. Carbon credit trading and CDM project execution are out of scope.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is Apache-2.0.

When your agent uses it

  • Carbon emissions
  • Carbon footprint requests

Example prompts

  • “GHG Protocol”
  • “carbon emissions”
  • “Scope 1/2/3”
  • “/ghg-protocol”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ghg Protocol loads about 1.1k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 341 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

GHG Protocol — Greenhouse Gas Protocol Guide

Enhances the environmental-analyst agent's carbon emission analysis capabilities.

Scope 1/2/3 Classification System

Scope 1: Direct Emissions
Emission SourceExamplesCalculation Method
Stationary CombustionBoilers, generatorsFuel consumption x Emission factor
Mobile CombustionCompany vehiclesFuel consumption x Emission factor
Process EmissionsChemical reactions, manufacturingProcess-specific emission factor
Fugitive EmissionsRefrigerant leaks, methaneCharge/refill amount x GWP
Scope 2: Indirect Emissions (Electricity)
Market-based:
  Emissions = Electricity consumption (MWh) x Supplier emission factor

Location-based:
  Emissions = Electricity consumption (MWh) x Grid average emission factor

Example grid emission factor:
  0.4594 tCO2eq/MWh (varies by country and region)
Scope 3: Other Indirect Emissions

Emission Calculation Formulas

Basic Formula
Emissions (tCO2eq) = Activity Data x Emission Factor x GWP

Key GWP values (AR6, 100-year basis):
  CO2: 1
  CH4: 27.9
  N2O: 273
  HFCs: 4-14,800
  SF6: 25,200

Reporting Framework Alignment

Major Frameworks
FrameworkPurposeGHG-Related Indicators
GRI 305General reporting305-1 through 305-5 (emissions by scope)
TCFDClimate financial disclosureStrategy, risk, targets
SBTiReduction targets1.5C / 2C pathways
CDPInvestor disclosureAll-scope emissions + strategy
ISSB S2Financial disclosureScope 1/2/3 + risks
Reduction Target Setting (SBTi)
Target types:
- Absolute reduction: Reduce emissions vs base year (e.g., 42% reduction by 2030)
- Intensity reduction: Reduce per unit of revenue/production (e.g., tCO2/revenue unit)

1.5C pathway: 4.2% annual reduction
2C pathway: 2.5% annual reduction

Base year: Select from most recent 2 years (ensure data completeness)
