Piped natural gas (PNG) emission factor (India): 2.05 kg CO2 per scm
Senseible uses 2.05 kg CO2 per scm of piped natural gas (Scope 1). An invoice for 1,000 scm is 1,000 × 2.05 = 2,050 kg CO2, or 2.05 tonnes.
| Factor | Scope | HSN heading | On invoices as |

| 2.05 kg CO2 per scm | Scope 1 | 2711 (Petroleum gases) | PNG, natural gas, standard cubic metres (scm) |
How the factor is derived
IPCC 2006 Guidelines, Vol. 2, Tables 1.2 and 1.4: natural gas 56,100 kg CO2 per TJ × 48.0 TJ per Gg = 2.69 kg CO2 per kg, × 0.76 kg per scm = 2.05 kg CO2 per scm.
The 0.76 kg per scm density is an assumption for typical pipeline gas; a supplier calorific value per scm should replace it when available.
Questions
What is the emission factor for piped natural gas in India?
2.05 kg CO2 per scm. IPCC 2006 Guidelines, Vol. 2, Tables 1.2 and 1.4: natural gas 56,100 kg CO2 per TJ × 48.0 TJ per Gg = 2.69 kg CO2 per kg, × 0.76 kg per scm = 2.05 kg CO2 per scm.
How do I calculate emissions from a piped natural gas invoice?
Multiply the scm on the invoice by 2.05. For 1,000 scm: 2,050 kg CO2.
Is piped natural gas Scope 1 or Scope 2?
Scope 1, when the fuel is burned in equipment or vehicles the business owns or controls. Fuel burned by a hired transporter is that transporter’s Scope 1 and your Scope 3.
