What emission factors sit behind the carbon dioxide column in the Coimbatore bakery profile?

Divide each printed figure by its quantity. In the profile by The Energy and Resources Institute (TERI), diesel is 2.55 kilograms of carbon dioxide (CO2) a litre, liquefied petroleum gas (LPG) 2.99 a kilogram, and electricity 0.097 a kilowatt hour (kWh), one seventh of today's 0.675. The power row is why the total looks low.

The column and its quantities

• Electricity 7.0 million kWh: 682 tonnes. Diesel 1,140 kilolitres: 2,905 tonnes. LPG 1,200 tonnes: 3,582 tonnes. Wood 9,000 tonnes: none shown.
• 682 + 2,905 + 3,582 = 7,169, so the printed total ties.

The factors that follow

• Electricity: 682,000 kg / 7,000,000 kWh = 0.097 kg a kWh.
• Diesel: 2,905,000 kg / 1,140,000 litres = 2.548 kg a litre. Today's 2.645.
• LPG: 3,582,000 kg / 1,200,000 kg = 2.985 kg a kilogram. Today's 2.98.

The same quantities at today's factors

• Electricity: 7,000,000 x 0.675 = 4,725 tonnes. Diesel: 1,140,000 x 2.645 = 3,015 tonnes. LPG: 1,200 x 2.98 = 3,576 tonnes. Total 11,316 tonnes against the printed 7,169.
• The gap is 4,147 tonnes, and the power row is 4,043 of it (4,725 minus 682). Diesel adds 110 and LPG takes off 6.
• The profile prints no grid factor and does not explain the power row. TERI's Gokak jaggery table implies 0.82 (our division), and the Bureau of Energy Efficiency Alwar manual states 0.86 tonnes per 1,000 units; 0.097 is far below both. We could not find the cause, so do not copy the 682.

For your own bakery

• Multiply your monthly kWh by 0.675, the financial year 2025-26 grid factor.
• Multiply oven diesel litres by 2.645 and LPG kilograms by 2.98.
• Report wood on a biogenic line of its own. The profile shows a dash for wood and does not say why (our reading: biogenic).

The cluster at today's factors (estimate)

• Printed: 682 + 2,905 + 3,582 = 7,169 tonnes
• Electricity: 7,000,000 kWh x 0.675 = 4,725,000 kg = 4,725 tonnes
• Diesel: 1,140,000 litres x 2.645 = 3,015,300 kg = 3,015 tonnes
• LPG: 1,200,000 kg x 2.98 = 3,576,000 kg = 3,576 tonnes
• Total 11,316 tonnes. Wood's CO2 is biogenic and not in it

Quantities are the profile's, dated 2016. Today's factors are the grid factor for the financial year 2025-26 and Senseible's diesel and LPG factors. The diesel factor of 2.645 uses the Central Electricity Authority's density of 0.83 kg a litre.

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so your kWh, diesel litres and LPG kilograms are on file by month, ready to multiply by current factors. It does not correct a published figure.
