GHG Emissions Inventory Analyzer
Build defensible GHG emissions inventories using Scope 1, 2, 3 and GHG Protocol standards
What You Can Do
You can systematically compile accurate GHG emissions inventories aligned with the Greenhouse Gas Protocol Corporate Standard, covering Scope 1 (direct), Scope 2 (energy), and Scope 3 (value chain) emissions. The skill guides you through data collection workflows, applies standardized calculation methodologies, validates completeness and accuracy, and produces documentation suitable for ESG reporting, investor disclosure, and regulatory compliance. You'll establish baseline metrics, identify data gaps, and create repeatable processes for annual inventory updates.
Features
systematically organize and classify all emission sources using GHG Protocol definitions
apply appropriate conversion factors, emission factors, and calculation approaches for each source category
cross-check completeness, reasonableness, and consistency of input data with automated flags for anomalies
generate audit trails, source documentation, and calculation transparencies required for third-party assurance
systematically add new facilities, business units, or value chain activities while maintaining historical comparability
identify missing data, estimate coverage rates, and prioritize data collection investments
format emissions results for ESG disclosures, CDP questionnaires, and science-based target submissions
position your emissions profile against sector and peer performance metrics
Example Output
Example 1: Scope 1 Emissions Summary
- Natural gas (facility heating): 250 metric tons CO₂e
- Company vehicle fleet (gasoline): 180 metric tons CO₂e
- Refrigerant leakage: 42 metric tons CO₂e
- Total Scope 1: 472 metric tons CO₂e
- Data quality: 95% (high confidence)
Example 2: Data Validation Report
- ✅ All 12 facilities included in inventory boundary
- ⚠️ Flag: Facility D electricity data incomplete for Q4 (estimated 5% of total)
- ✅ Scope 3 supplier emissions: 8,200 metric tons CO₂e (45 suppliers surveyed, 78% response rate)
- Recommendation: Implement automated utility metering for Facility D by Q2
Example 3: Historical Trend Analysis
- 2022: 15,400 metric tons CO₂e
- 2023: 14,800 metric tons CO₂e
- Year-over-year reduction: 3.9% (driven by renewable energy procurement)
What's Included
- SKILL.md instruction file: complete GHG Protocol methodology and inventory build workflow
- Scope 1, 2, 3 classification framework: standardized source categorization templates aligned with GHG Protocol definitions
- Emissions calculation checklist: data inputs, conversion factors, and quality checks for each scope
- Data validation and gap analysis template: completeness assessment, reasonableness tests, and improvement roadmap

You can model the economic, environmental, and social impacts of proposed circular economy policies across multiple dimensions—material flows, value chain economics, distributional effects, and implementation feasibility. This skill helps you build defensible policy recommendations grounded in quantitative analysis and develop compelling evidence narratives for stakeholder engagement, whether you're designing Extended Producer Responsibility schemes, circular procurement mandates, waste reduction policies, or comparing regulatory alternatives.

You can consolidate emissions data from multiple sources (utility bills, vehicle logs, supplier reports) and calculate Scope 1, 2, and 3 emissions using standardized emission factors from IPCC, EPA, DEFRA, and supplier-specific databases. Claude helps you reconcile data anomalies, identify high-impact reduction opportunities, and generate audit-ready documentation that explains methodology and assumptions for third-party verification and compliance reporting.

You can systematically map environmental, social, and governance issues to financial performance and stakeholder priorities specific to your organization's business model and industry. This skill helps you move ESG from compliance activity to strategic decision-making framework by conducting double materiality analysis, quantifying financial impact, and translating assessment results into integrated business strategy that informs executive compensation, capital allocation, risk management, and stakeholder engagement.

You can conduct comprehensive remanufacturing feasibility assessments that evaluate technical viability, economic feasibility, environmental impact, and market demand. This skill guides you through product design analysis, disassembly evaluation, cost-benefit modeling, and ROI projections—enabling you to determine which products represent genuine circular economy opportunities versus those better suited to recycling or disposal. You'll generate detailed feasibility reports with specific recommendations and risk assessments.

You can rapidly analyze climate policy proposals by quantifying emissions reduction pathways, calculating cost-effectiveness ratios, identifying implementation constraints, and assessing who bears costs versus benefits. This skill structures analysis around the specific metrics, assumptions, and trade-offs that climate policymakers need for credible decision-making, surfacing risks like sectoral interactions, cost escalation, and political economy constraints that generic policy reviews miss.
