What it does

Carbon Accounting Check is an agent skill from mohitagw15856/pm-claude-skills. Sanity-check a greenhouse gas inventory before it goes into a report or gets audited. Use when asked to review a carbon footprint, check a GHG inventory, validate scope 1/2/3 numbers, explain a year-over-year emissions change, or prepare emissions data for assurance. Produces a boundary review, data-quality assessment, emission-factor sensitivity list, YoY bridge, and a fix-before-publishing list.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Accounting and bookkeeping and Data cleaning. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked to review a carbon footprint
  • Check a GHG inventory
  • Validate scope 1/2/3 numbers
  • Explain a year-over-year emissions change

Example prompts

  • “/carbon-accounting-check”

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. 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

Carbon Accounting Check loads about 1.6k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 823 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~106
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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.

description
Sanity-check a greenhouse gas inventory before it goes into a report or gets audited. Use when asked to review a carbon footprint, check a GHG inventory, validate scope 1/2/3 numbers, explain a year-over-year emissions change, or prepare emissions data for assurance. Produces a boundary review, data-quality assessment, emission-factor sensitivity list, YoY bridge, and a fix-before-publishing list.

Carbon Accounting Check Skill

A GHG inventory fails audit (and credibility) on boundaries, factors, and data quality — rarely on arithmetic. This skill runs a structured sanity pass over an inventory so the weak points are found internally, not by an assurer or a journalist. It reviews rigor; it does not certify compliance.

What This Skill Produces

  • A scope 1/2/3 boundary review with gaps and out-of-boundary items named
  • A data-quality tier map (measured / calculated / estimated / proxy) per emission source
  • The top emission-factor sensitivities — where a factor choice swings the total
  • A year-over-year bridge separating real reduction from methodology or boundary change
  • Double-counting flags and a prioritized fix list

Required Inputs

Ask for these if not provided; if the brief is thin, proceed with clearly labelled assumptions rather than refusing:

  • Inventory data — emissions by scope and category, with units (tCO2e), and the reporting year
  • Organizational boundary — operational control, financial control, or equity share, and which entities are in/out
  • Scope 2 method(s) — location-based, market-based, or both; contractual instruments held (RECs, GOs, PPAs)
  • Emission factor sources — which factor sets and vintages were used per category
  • Data provenance — per major source: meter/invoice, activity-data calculation, estimate, or spend-based proxy
  • Prior-year inventory (optional) — needed for the YoY bridge
  • Offsets or removals held (optional) — reviewed separately, never netted

Review Framework

Walk the inventory in this order:

1. Boundary. Confirm the consolidation approach is stated and applied consistently. For scope 3, check all 15 GHG Protocol categories were screened — a category may be excluded only with a stated reason and a rough size estimate.

2. Scope 2 duality. Both market- and location-based figures should exist. Flag market-based claims without matching contractual instruments (vintage, geography, retirement).

3. Data-quality tiers. Assign each material source a tier and estimate what share of the total sits in each:

TierBasisTypical uncertainty
MeasuredMeters, fuel invoices, utility billsLow
CalculatedActivity data × published factorLow–medium
EstimatedExtrapolation, averages, occupancy modelsMedium–high
ProxySpend-based, industry-average intensityHigh — directional only

Flag any headline claim (e.g. "-12% YoY") that rests mostly on proxy-tier data.

4. Factor sensitivity. Identify the 3–5 sources where switching to an equally defensible factor set or vintage moves the total by >2%. Recompute or estimate the swing.

5. YoY bridge. Decompose the change into: activity change, factor/vintage updates, boundary changes, methodology changes, and data-quality improvements. Only the first is a real emissions trend.

6. Double-counting traps. Check the classics: fleet fuel in both scope 1 and scope 3 category 6; electricity in scope 2 and again via spend-based scope 3; parent and subsidiary both claiming the same site; RECs claimed against grid averages already lowered by those RECs; leased assets counted by both lessor and lessee.

GHG inventory check: [organization, reporting year]

1. Summary verdict — publishable as-is / publishable with caveats / fix first, with the two or three decisive reasons.

2. Boundary review — consolidation approach, scope 3 category screening table (included / excluded + reason + size estimate), gaps.

3. Data-quality map — table of major sources × tier × share of total, with the weakest material sources called out.

4. Factor sensitivities — the top swings, each with source, alternative factor, and estimated delta.

5. YoY bridge — waterfall from prior year to current year with each driver quantified or labelled as an estimate.

6. Flags and fixes — numbered list, each with severity (blocks publication / caveat needed / improve next cycle) and a concrete fix.

Include this line in the artifact: "Verify boundary, methodology, and disclosure choices against the applicable standard (e.g. GHG Protocol, ISO 14064-1) and regulation with your compliance team and assurer."

Quality Checks

  • Consolidation approach is stated and every in/out entity decision is visible
  • All 15 scope 3 categories are screened; exclusions have a reason and a size estimate
  • Both scope 2 methods are reported, or the absence of one is flagged
  • Every material source has a data-quality tier; the share of total per tier is stated
  • The YoY bridge separates real activity change from methodology and boundary effects
  • Each flag has a severity and a concrete fix, not just an observation
  • Assumptions made from a thin brief are labelled as assumptions

Anti-Patterns

  • Do not net offsets or removals against gross emissions in the headline number — report gross, then offsets separately
  • Do not present a market-based scope 2 figure without naming the contractual instruments behind it
  • Do not let a YoY "reduction" stand if it is driven by a factor-vintage update or boundary change — say so
  • Do not treat spend-based proxy data as if it supports precise claims — flag it as directional
  • Do not silently drop scope 3 categories — every exclusion needs a reason and a size estimate
  • Do not certify compliance — this is a rigor review; assurance and legal sign-off stay with the professionals

Based On

GHG Protocol Corporate Standard and Scope 2/Scope 3 guidance practice (boundaries, dual reporting, data-quality tiers, recalculation policy).

Example Trigger Phrases

  • "Review a carbon footprint."
  • "Check a GHG inventory."
  • "Validate scope 1/2/3 numbers."
  • "Explain a year-over-year emissions change."
  • "Prepare emissions data for assurance."
