## Environment variables

| Name | Required | Secret | Description |
|---|---|---|---|
| `EIA_API_KEY` | no | yes | Free US EIA-930 grid data API key (optional; enables live US carbon). |
| `ELECTRICITYMAPS_TOKEN` | no | yes | Electricity Maps API token (optional; used when GREENPICK_CARBON_SOURCE=electricitymaps). |
| `ENTSOE_TOKEN` | no | yes | Free EU ENTSO-E grid data token (optional; enables live EU carbon + day-ahead forecast). |
| `GREENPICK_CACHE_TTL_SECONDS` | no | no | Cache lifetime for fetched grid data, in seconds. |
| `GREENPICK_CARBON_SOURCE` | no | no | Carbon data source: 'auto' (US->EIA, EU->ENTSO-E, Canada->Hydro-Québec/IESO live), 'mock' (offline: typical monthly values from a year of real data), 'eia', 'entsoe', or 'electricitymaps'. Defaults to offline. |
| `GREENPICK_LOG_LEVEL` | no | no | Logging level (DEBUG, INFO, WARNING, ERROR). |

## FAQ

### Does GreenPick require API keys to start?

No, it works offline or without API keys by falling back to clearly-labelled typical values based on a year of real data.

### Is GreenPick an audited carbon accounting tool?

No, it is a design-time guidance tool for developers and does not claim GHG-Protocol or ISO compliance.

### Which cloud providers are supported?

The server supports AWS, GCP, and Azure across 25 regions including the US, Europe, Canada, Asia, and Australia.
