# Delayed Environmental Clearance ROI & Carrying Cost Calculator

Environmental review delays are massive financial drains on proponent equity, committed financing, and contractor remobilization.

## Capital Carrying Cost Formula
- `Delayed Capital Cost = Capital Outlay * Annual Cost of Capital (12%) * (Delay Months / 12)`
- Typical formal agency inquiry delay duration: 9 to 14 months across review authorities.

## Representative Proponent Savings
1. **Clean Energy & Battery Storage (450 MW Solar + BESS), SW United States (BLM / NEPA)**: Outlay $420M USD | Delay Saved: 11 Mo | Capital Saved: $46.2M USD. Resolved cumulative groundwater drawdown conflicts and Desert Tortoise habitat corridor buffers up-front, eliminating a formal Supplemental EIS mandate.
2. **Offshore Wind & Green Hydrogen (120 MW), North Sea Basin (EU EIA Directive)**: Outlay €310M EUR | Delay Saved: 9 Mo | Capital Saved: €30.2M EUR. Flagged Natura 2000 marine cable landfall mitigation deficit and hydroacoustic noise thresholds before agency review submission.
3. **Critical Minerals Extraction (Hard-Rock Lithium), Western Australia (EPBC Act & WA EPA)**: Outlay A$580M AUD | Delay Saved: 14 Mo | Capital Saved: A$81.2M AUD. Addressed subterranean stygofauna sampling gaps and pit lake post-closure hydrogeology balance before formal Environmental Review Document submission.
