HiQ Cortex — LCA Data Search & Carbon Footprint AI
Find carbon emission factors for any material, product, or process — covering China's full industrial system (HiQLCD), global data (Ecoinvent), and chemicals (CarbonMinds). Calculate carbon footprints from Bills of Materials. ISO 14040/14044 compliant.
Privacy & Security
This skill reads HIQ_API_KEY from your environment and sends queries to x.hiqlcd.com only. No other data is collected or transmitted.
MCP Server (Cursor / Claude Desktop / Claude Code)
If you use Cursor, Claude Desktop, or Claude Code, you can skip this skill and connect directly via MCP:

Tools
1. Search LCA Datasets
Search databases for emission factors. Returns structured data with GWP values, dataset links, region, and data quality.
./search.js "stainless steel 304" # Search all databases
./search.js "polyethylene HDPE" --sources "HiQLCD" # Only HiQLCD
./search.js "cement" --sources "Ecoinvent:3.12.0" # Specific version
./search.js "aluminum" --sources "HiQLCD|Ecoinvent:3.12.0" # Multiple sources
Available --sources: HiQLCD, Ecoinvent, CarbonMinds, HiQLCD-AL. Omit for all.

2. Ask LCA Questions
Natural language AI assistant for LCA, carbon footprint, sustainability. Supports calculations, comparisons, and research.
./ask.js "calculate carbon footprint for 100kg steel + 50kg aluminum"
./ask.js "compare environmental impact of PET vs HDPE"
./ask.js "what are the main contributors to cement carbon footprint?"
./ask.js "explain cut-off vs consequential system models"
./ask.js "中国钢铁行业的平均碳排放因子是多少?"
The assistant can:
- Calculate carbon footprints from BOM (Bill of Materials)
- Compare materials and suggest lower-impact alternatives
- Search and interpret Ecoinvent/HiQLCD datasets
- Answer LCA methodology questions (GWP, system boundaries, allocation, ISO 14040/44)
- Research sustainability topics, EPDs, and industry reports
When to Use
- User asks about carbon footprint, emission factors, GWP, or LCA
- User wants to find environmental impact data for materials or processes
- User mentions Ecoinvent, HiQLCD, or life cycle assessment
- User has a Bill of Materials and wants carbon footprint calculations
- User asks about sustainability, ISO 14040, EPD, or carbon neutrality
- User mentions Chinese supply chain, CBAM, battery passport, or Scope 3 emissions
- User asks about China-specific emission factors vs global averages
When NOT to Use
- General chemistry or material science questions unrelated to environmental impact
- Financial carbon credits or carbon trading (this tool covers physical carbon footprint)
