How do I calculate the carbon footprint of chocolate per kg?

Cocoa and milk ingredients usually dominate. Add cocoa mass, butter or powder, milk powder, sugar and fats from supplier or database factors, then refining, conching, tempering and cooling energy, and wrappers. Divide by kilograms packed. Cocoa linked to deforestation carries land use emissions.

Ingredients

• Cocoa beans, mass, butter or powder: high per kg where growing has cleared forest.
• Milk powder in milk chocolate: dairy footprint.
• Sugar, vegetable fats, emulsifiers and nuts.

Plant energy

• Roasting, refining and conching: electricity and heat over long cycles.
• Tempering, moulding and cooling tunnels.
• Air conditioning for storage.

Per kg

Report dark, milk and compound chocolate separately: their recipes differ. If you buy compound or couverture rather than beans, use the supplier's per-kg figure as one input.

Worked example: chocolate plant per kg (one month)

• Electricity: 50,000 kWh x 0.710 = 35,500 kg CO2
• Chocolate packed (kg): 40,000
• Plant total: 35,500 / 40,000 = 0.887 kg CO2 per kg
• Add cocoa, milk powder, sugar and wrappers for the full figure

Inputs are illustrative; use your own bills and production records.

What Senseible does here

Senseible reads the plant's electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and fuel invoices (IPCC 2006 defaults) into a fingerprinted Scope 1 and 2 record, the plant-level input to a per-unit figure. Bought-in materials go to the supplier evidence trail; product reports are self-declared drafts.
