openclaw skills install hiq-cortexFind 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.
This skill reads HIQ_API_KEY from your environment and sends queries to x.hiqlcd.com only. No other data is collected or transmitted.
If you use Cursor, Claude Desktop, or Claude Code, you can skip this skill and connect directly via MCP:

"cortex": {
"url": "https://x.hiqlcd.com/api/deck/mcp",
"headers": { "X-API-Key": "sk_xxx" }
