What is the carbon footprint of a solar lantern?
Add the small solar panel, the battery (lithium-ion or lead-acid), the LED board, the plastic body and packaging. Batteries and the panel usually carry the most. If you claim it replaces a kerosene lamp, report that avoided figure separately from the lantern's own footprint.
What to weigh
- Solar cell area or panel watt rating.
- Battery chemistry and capacity.
- Plastic body, LEDs and circuit board.
Avoided emissions
Avoided kerosene use is not a reduction in your inventory. Show it as a separate claim with its assumptions.
What Senseible does here
Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
