Can we call our factory coal-free, and what proves it?
Only if no coal or coal-derived fuel is burned on site, and you say what the claim covers. Grid electricity in India is still largely coal-fired, so coal-free on site is not coal-free power. Keep twelve months of fuel invoices showing no coal, pet coke or lignite, and word the claim exactly.
Safe wording
- "No coal burned on site since April 2025."
- "Process heat from biomass and natural gas."
- Avoid "coal-free" alone if you use grid power.
Evidence
- Fuel purchase invoices for the period.
- Boiler logbooks showing fuels used.
- Electricity source documents if you claim renewable power.
What Senseible does here
