How do I calculate the carbon footprint of a mixer grinder?

Weigh the motor's copper and steel, the stainless steel jars and blades, the plastic body and the packaging, apply supplier or database factors, and add assembly and testing electricity per unit. Report use-phase electricity separately. Motor and jars are usually the largest parts.

Bill of materials

• Universal motor: copper winding, electrical steel laminations, brushes.
• Stainless steel jars and blades: weigh a full jar set.
• ABS or PP body, couplers, switch and cord.
• Carton and EPS or moulded pulp inserts.

Assembly

• Motor winding, varnish baking ovens and assembly lines.
• Run testing of each unit.
• Bought-in motors carry their maker's footprint; ask for it.

Use phase

A 750 W mixer used briefly each day uses far less electricity than a fan or fridge, but over years it adds up. Show it separately with assumed minutes per day.

Worked example: mixer assembly per unit (one month)

• Electricity: 30,000 kWh x 0.710 = 21,300 kg CO2
• Units passed: 20,000
• Plant total: 21,300 / 20,000 = 1.06 kg CO2 per unit
• Add motor, jars, body and packaging 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.
