- Climate Action Reserve - 7% market share
## CLI Commands
```bash
# EU ETS price history (default: 365 days)
python3 cli.py eu-ets-price [days]
# Global carbon prices across all compliance markets
python3 cli.py global-prices
# Comprehensive market statistics and trends
python3 cli.py market-stats
# Emissions breakdown by sector (EU, UK, USA)
python3 cli.py emissions-by-sector [jurisdiction]
# Compare carbon pricing mechanisms

"high": 93.0,
"low": 78.0,
"volatility_pct": 17.63
}
}
```
### Compare Global Carbon Markets
```bash
$ python3 cli.py global-prices

"UK ETS": {"price_usd": 57.53},
"California Cap-and-Trade": {"price_usd": 31.50}
}
}
```
### Emissions by Sector

{
"total_emissions_mt_co2e": 427,
"carbon_pricing_coverage_pct": 31,
"reduction_target_2030_pct": 68
}
```

## Testing
✅ All 6 CLI commands tested and working
✅ Mock data based on realistic 2023-2024 market trends
✅ MCP tools registered and handlers implemented
✅ Roadmap updated: Phase 177 marked as DONE with 630 LOC
## Production Deployment Notes
Current implementation uses mock data based on historical trends. For production:
1. Register for **EEX API** access for real-time EU ETS prices
2. Integrate **ICAP Status Report** API for global compliance market data
3. Connect to **Ember Climate** data feed for emissions data
4. Add **World Bank Carbon Pricing Dashboard** API for historical trends
5. Implement **Verra/Gold Standard APIs** for voluntary market data
## Future Enhancements
- Real-time price feeds from exchanges
- Alert system for significant price movements
- Carbon credit portfolio tracking
- Offset project quality scoring
- Carbon accounting calculator
- Paris Agreement compliance tracking
- Scope 1/2/3 emissions calculator
