How CarbonTrack
Calculates Emissions
Complete transparency on every emission factor, formula, and data source we use. Verify our calculations yourself.
CarbonTrack reports are generated using CEA 2023-24 emission factors and IPCC 2006 guidelines. All reports should be reviewed and signed off by a registered environmental auditor or CA firm before official SEBI submission. CarbonTrack provides the calculation engine and report format — the auditor provides the verification signature.
Emission Factors We Use
Every factor is sourced from official government and international bodies. We never use estimated or proprietary factors.
| Fuel / Energy Type | Emission Factor | Unit | Source |
|---|---|---|---|
| Grid Electricity (India) | 0.7117 | tCO2e per MWh | CEA India — CO2 Baseline Database ver 21.0, November 2025 |
| HSD Diesel | 2.7055 | kgCO2e per litre | DEFRA 2024 Guidelines |
| LPG | 2.93 | kgCO2e per kg | DEFRA 2024 Guidelines |
| Natural Gas | 2.022 | kgCO2e per m3 | DEFRA 2024 Guidelines |
| PNG | 2.204 | kgCO2e per kg | IPCC 2006 Guidelines, Volume 2, Table 2.2 |
| Petrol | 2.164 | kgCO2e per litre | DEFRA 2024 Guidelines |
| Furnace Oil | 3.176 | kgCO2e per litre | DEFRA 2024 Guidelines |
| Coal (Industrial) | 2.422 | kgCO2e per kg | DEFRA 2024 Guidelines |
| Business Travel (Road) | 0.143 | kgCO2e per km | DEFRA 2024, GHG Protocol |
The Exact Formulas We Use
Grid Electricity
HSD Diesel
LPG (Boiler / Process Fuel)
Calculation Method
We use the Location-Based Method for Scope 2 calculations as defined by the GHG Protocol Corporate Standard. This uses the average emission intensity of the regional electricity grid rather than supplier-specific factors. This is the method accepted by SEBI for BRSR Core reporting.
Verify Our Calculations Yourself
Every number CarbonTrack produces can be verified manually. Here is proof our calculation engine is accurate.
| Input Data | Our Calculation | Result | Status |
|---|---|---|---|
| 12,450 kWh electricity | 12,450 ÷ 1000 × 0.7117 | 8.860 tCO2e | Verified |
| 2,850 litres diesel | 2,850 × 2.7055 ÷ 1000 | 7.710 tCO2e | Verified |
| 450 kg LPG | 450 × 2.93 ÷ 1000 | 1.318 tCO2e | Verified |
| 8,720 kWh electricity | 8,720 ÷ 1000 × 0.7117 | 6.206 tCO2e | Verified |

Your Data Never Leaves India
Mumbai Servers
All emission data is stored on Supabase servers located in Mumbai, India (ap-south-1 region). Your data never leaves Indian borders.
Row Level Security
We use Supabase Row Level Security (RLS) ensuring your company's data is completely isolated from every other company on the platform. No data sharing, ever.
Role-Based Access
Owner, Member, and Auditor roles with granular permissions. Auditor access is time-limited and automatically expires. Every action is logged.
ISO 14064 Ready — CarbonTrack includes a downloadable Data Collection SOP Template aligned with ISO 14064-1 verification requirements. Available inside the platform under Reports.
