Why does the Ramnagar plastics cluster profile print 28,503 tonnes of carbon dioxide when today's factors give about 20,000?

The Ramnagar profile prints 28,503 tonnes of carbon dioxide (CO2) for 27.8 million kilowatt-hours, 452 kilolitres of diesel and 36 tonnes of liquefied petroleum gas (LPG). Its power line implies 0.98 kg a kWh. At 0.675 for financial year (FY) 2025-26 the same energy gives 20,068 tonnes, and power explains all of the gap.

What the profile prints

• Electricity 27.8 million kWh: 27,244 tonnes of CO2, which is 0.980 kg a kWh. Diesel 452 kilolitres: 1,152 tonnes, 2.55 kg a litre. LPG 36 tonnes: 107 tonnes, 2.97 tonnes a tonne.
• Total 27,244 + 1,152 + 107 = 28,503 tonnes. The profile prints no factor. Its diesel price is dated 27 November 2015.

Where the gap sits

• Electricity at 0.675 kg a kWh (FY 2025-26): 27.8 million x 0.675 = 18,765 tonnes, 8,479 less than printed.
• Diesel at 2.645 kg a litre: 452,000 x 2.645 = 1,196 tonnes, 44 more than printed. LPG at 2.98: 36 x 2.98 = 107 tonnes, no difference.
• Net: 28,503 minus 20,068 is 8,435 tonnes. The power line is the whole gap, and the diesel line pulls 44 tonnes the other way.

Other profiles imply similar factors

The Rajkot plastics profile prints 81,322 tonnes for 83 million kWh, about 0.98 as well. The Pune rubber profile, from 2018, implies 0.82. The Chennai forging profile also implies 0.986 (see the linked page). The Central Electricity Authority's average for 2014-15 was 0.779, and no figure of its matches 0.98. We cannot tell which factor was used: the profiles print and source none, and our reading is that they were not all built on one factor.

The grid factor is updated each year. Use 0.675 for FY 2025-26 and 0.710 for FY 2024-25 when a buyer asks about those years. Do not set a current unit's kWh against a cluster CO2 line whose factor is not stated.

A unit using 100,000 kWh a year (example quantity)

• At the profile's implied 0.98: 100,000 x 0.98 = 98,000 kg, 98.0 tonnes
• At 0.710 (FY 2024-25): 71.0 tonnes
• At 0.675 (FY 2025-26): 67.5 tonnes, which is 31 percent below 98.0
• Cluster: 28,503 printed against 20,068 now; electricity share 27,244 / 28,503 = 95.6 percent printed, 18,765 / 20,068 = 93.5 percent now

The 100,000 kWh is an example. The gap comes from the factor the printed line implies against today's, not from any change in how much power the cluster uses.

What Senseible does here

Senseible reads fuel invoices and electricity bills into dated, fingerprinted records, so your kilowatt-hours and litres are on file by date. A cluster table does not replace your own bills.
