Carbon verification requires evidence. Here's exactly what documents you need to calculate and verify your emissions.

**Scope 1 Documents (Direct Emissions):**

- Fuel purchase invoices (diesel, petrol, LPG, CNG)
- Fuel consumption logs
- Vehicle fleet records
- Generator run-time logs
- Refrigerant purchase/refill records

**Scope 2 Documents (Electricity):**

- Electricity bills (monthly or annual)
- Power purchase agreements (if applicable)
- Renewable energy certificates (RECs)
- Solar/wind generation records

**Scope 3 Documents (Value Chain):**

- Supplier invoices (raw materials)
- Freight and logistics bills
- Business travel records
- Waste disposal receipts
- Employee commute surveys

**What Senseible Accepts:**

- PDF invoices and bills
- Images/photos of documents
- Scanned copies
- Even voice descriptions of expenses

**Minimum Viable Start:**

You don't need everything. Start with:

1. One electricity bill (Scope 2 baseline)
2. One fuel invoice (Scope 1 baseline)

For [BRSR reporting](https://senseible.earth/climate-intelligence/brsr-reporting-requirements-india), you'll need 12 months of data. For [carbon credits](https://senseible.earth/carbon-credits), continuous tracking helps.
