Replaces generic ESG checklists with an asset-specific, framework-anchored register. ## When to Use Invoke this skill when the user asks to: - Conduct an ESG materiality assessment for a specific infrastructure asset or portfolio - Identify which ESG issues are most material for a transport, energy, water, or social infrastructure project - Map ESG issues to stakeholder concerns and reporting framework disclosures - Prepare the materiality basis for a TCFD, GRI, or SASB sustainability report - Build an ESG strategy, KPI set, or due diligence framework for an infrastructure fund or project sponsor ## Inputs Required Before starting, collect: - **Asset type**: Transport / Energy / Water / Social infrastructure (and sub-type — e.g., toll road, solar farm, desalination plant, hospital) - **Project stage**: Greenfield development / Construction / Operations / Brownfield acquisition / Refinancing - **Geography**: Country or region, including regulatory regime if known - **Ownership and tenor**: Fund hold period, equity vs. debt, public-private structure - **Key stakeholders**: Investors/LPs, lenders, regulators, host communities, offtakers, employees — note any with elevated influence - **Reporting obligations**: Which frameworks or standards apply (TCFD, GRI, SASB, ISSB, EU Taxonomy/CSRD, lender ESG covenants) - **Known sensitivities**: Any existing controversies, permits at risk, community opposition, or climate exposure already identified If project stage or reporting obligations are missing, assume operations stage and full TCFD/GRI/SASB alignment, and note the assumption. ## Instructions ### Step 1: Establish the Asset ESG Profile Anchor the assessment to the specific asset before listing issues. - Classify the asset by its physical and revenue characteristics (e.g., merchant vs. contracted revenue, point-source vs. linear, water-intensive vs. land-intensive) - Note the dominant ESG exposures inherent to this asset class — do not treat all infrastructure the same: - **Transport**: emissions in use, community severance, air/noise pollution, induced demand, modal shift, labor in construction - **Energy**: GHG intensity, transition risk, grid/curtailment, land and biodiversity, rare-earth/supply chain, just transition - **Water**: water security and scarcity, effluent and discharge quality, energy intensity, affordability and access, ecosystem dependency - **Social (hospitals, schools, social housing, etc.)**: service quality and access, safeguarding, accessibility, embodied carbon, operational resilience, affordability - State the stage-specific lens: construction-stage assets weight occupational health, supply chain labor, and biodiversity disturbance higher; operational assets weight emissions in use, community relations, and governance higher ### Step 2: Build the ESG Issue Longlist (E / S / G) Generate a longlist of 18–24 candidate issues organized under Environmental, Social, and Governance. For each issue capture a one-line definition specific to the asset (not a generic label). - **Environmental**: climate mitigation (GHG), climate adaptation/physical risk, biodiversity and land use, water and effluent, pollution and waste, resource and circularity - **Social**: community health and safety, occupational health and safety, labor and human rights (incl. supply chain), land acquisition and resettlement, stakeholder and community engagement, access/affordability/service quality, Indigenous rights where relevant - **Governance**: board and ownership governance, business ethics and anti-bribery, regulatory compliance and permitting, climate governance and disclosure, cybersecurity and data, asset resilience and business continuity ### Step 3: Score Each Issue on a Double-Materiality Basis Score every longlisted issue on two axes, 1–5 each: - **Impact materiality (inside-out)**: severity and likelihood of the asset's impact on people and environment - **Financial materiality (outside-in)**: likelihood and magnitude of the issue affecting enterprise value — revenue, cost, cost of capital, license to operate, asset value - Compute a combined priority and assign a tier: - **Tier 1 — Critical** (high on either axis, or moderate-high on both) - **Tier 2 — Significant** - **Tier 3 — Monitor** - Briefly justify each score with an asset- and geography-specific rationale — not "climate is important," but the specific transmission mechanism (e.g., "physical heat risk reduces solar inverter efficiency and raises O&M in this region") ### Step 4: Map Issues to Stakeholders For each Tier 1 and Tier 2 issue, identify: - **Primary stakeholders affected or concerned** (from the input list — e.g., host community, lenders, regulator, LPs) - **Their specific concern** in one sentence - **Stakeholder influence**: High / Medium / Low — note where a high-influence stakeholder intersects a high-materiality issue (these are the escalation priorities) ### Step 5: Align Issues to Reporting Frameworks For each Tier 1 and Tier 2 issue, map to the relevant disclosure points: - **TCFD**: which pillar(s) — Governance / Strategy / Risk Management / Metrics & Targets — and the specific climate-related risk type (physical acute/chronic, transition policy/market/technology/reputation) where applicable - **GRI**: the relevant GRI Standard(s) (e.g., GRI 305 Emissions, GRI 303 Water, GRI 403 OH&S, GRI 413 Local Communities) - **SASB**: the applicable SASB Infrastructure sector standard and disclosure topic/metric (e.g., Engineering & Construction, Electric Utilities, Water Utilities) appropriate to the asset - Flag any material issue with no clean framework home — this signals a disclosure gap to address narratively ### Step 6: Produce the Materiality Matrix and Recommended Actions - Present the double-materiality matrix (impact axis × financial axis) with issues plotted by tier - For the top 5–7 issues, recommend a concrete next action: a KPI to track, a management measure, a disclosure to prepare, or a due-diligence question to resolve - State the single highest-priority issue and why it leads the register ## Output Format - **Structure**: Asset profile → E/S/G longlist → scored register table → stakeholder mapping → framework alignment table → materiality matrix and recommended actions - **Length**: 1,100–1,500 words - **Format**: Mix of structured tables (scoring register, framework mapping) and concise prose; the matrix described in a plotted/tiered layout - **Sections**: Asset ESG Profile; ESG Issue Longlist; Double-Materiality Scoring Register; Stakeholder Mapping; Framework Alignment (TCFD/GRI/SASB); Materiality Matrix & Recommended Actions - **Tone**: Infrastructure ESG advisor — analytical, framework-literate, and decisive; written for an investment committee and a sustainability report, not a brochure ## Quality Checklist Before delivering output, verify: - [ ] The longlist contains 18–24 issues with a coverage across all three of E, S, and G - [ ] Every issue is scored on both materiality axes (impact and financial) and assigned a Tier - [ ] Issue definitions are specific to the named asset type and geography — no generic labels - [ ] Every Tier 1 and Tier 2 issue is mapped to at least one of TCFD, GRI, or SASB with a named standard/disclosure (not just the framework name) - [ ] Stakeholder mapping flags every intersection of a high-influence stakeholder and a Tier 1 issue - [ ] A single highest-priority issue is named with a clear rationale — no hedging ## Notes - Double materiality is the default because most infrastructure now reports under regimes (CSRD/ISSB-influenced) that demand both impact and financial lenses; if the user only needs financial materiality, score that axis only and say so - The most common error is treating infrastructure as homogeneous — a toll road and a desalination plant share almost no top-tier issues; force the asset-specific lens in Step 1 - Construction-stage and operational-stage assets produce materially different registers for the same asset; re-run this skill at stage transitions rather than reusing an old assessment - Where the asset is in an emerging market or involves resettlement or Indigenous land, weight social issues higher and reference IFC Performance Standards alongside the named frameworks --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
