At a glance

Estimate embodied carbon and produce ESG/climate reporting for construction: LCA per work item, material-based carbon factors, EU taxonomy and CSRD alignment.

  • A project needs carbon estimates
  • SKILL.md covers Why it matters now, Method, Data sources for factors and What to compute per project, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Sustainability reporting

What it does

Embodied Carbon Esg is an agent skill from datadrivenconstruction/DDC_Skills_for_AI_Agents_in_Construction. Estimate embodied carbon and produce ESG/climate reporting for construction: LCA per work item, material-based carbon factors, EU taxonomy and CSRD alignment. Use when a project needs carbon estimates or sustainability reporting.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 221 AI skills for construction: BIM analysis, cost estimation, scheduling, document control, and automation with Claude Code. The licence is MIT.

When your agent uses it

  • A project needs carbon estimates
  • Sustainability reporting

Example prompts

  • “/embodied-carbon-esg”

What it can do on your machine

Read from SKILL.md and the folder at commit ce45bbf. 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

    Links to these hosts (documentation or services it may open):

    • oekobaudat.de
    • circularecology.com
    • finance.ec.europa.eu

    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

Embodied Carbon Esg loads about 664 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 257 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~664

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.

Embodied Carbon & ESG for Construction (2026)

Why it matters now

From 2026 the EU CSRD (Corporate Sustainability Reporting Directive) and EU Taxonomy force contractors and developers to report embodied carbon (A1–A5 life-cycle modules), not just operational energy. Estimators need carbon numbers next to price numbers at the BOQ line level.

Method

Carbon = quantity × carbon factor, applied per material resource line — exactly parallel to quantity × unit price = cost.

work item → components[] → material lines → quantity × EF (kg CO₂e / unit) → line carbon
BOQ roll-up: Σ line carbon = project embodied carbon (A1–A3) + transport/waste (A4–A5)

Data sources for factors

SourceCoverageLicense
ÖKOBAUDAT (DE)building materialsopen
INIES (FR) FDESproductsopen
ICE Database (UK)embodied carbonfree registration
EPD libraries (ECO Platform)manufacturer EPDsvaries

The CWICR bases already carry per-resource quantity and unit — attach an EF (kg CO₂e/unit) column for the materials and the roll-up is automatic.

What to compute per project

  • A1–A3 embodied carbon per BOQ section and per trade (from material lines).
  • A4–A5 transport + site waste assumptions (distance bands, waste rates per material).
  • kg CO₂e / m² and / m³ intensity benchmarks for early design.
  • Hotspot report: top 10 carbon lines (usually concrete, steel, aluminium, insulation).

EU Taxonomy / CSRD alignment

  • Map each work item to the taxonomy activity (construction of new buildings 7.1, renovation 7.2, …).
  • Report DNSH (Do No Significant Harm) screening: circularity, waste, water for the top materials.
  • Keep the evidence trail: factor source + version per line (auditors ask).

Honest limits

  • Carbon factors are regional and versioned — never mix databases without noting it.
  • BIM takeoff gives geometry; carbon needs material takeoff (from CWICR resource_name + resource_quantity).
  • Early-phase estimates are ±30–50%; label them as such.
