How do I calculate emissions from curing tobacco in flue-cured barns?
Weigh the coal or firewood burned per barn season and divide by kilograms of cured leaf. Coal CO2 is fossil and counts fully; firewood CO2 is biogenic and reported separately. Fuel per kilogram varies widely with barn insulation and furnace design.
Records
- Coal tonnes or firewood kilograms per barn.
- Green leaf loaded and cured leaf out.
- Number of curings in the season.
Reducing it
Insulated barns and better furnaces cut fuel per kilogram, and the per-kg figure shows the gain.
One barn season
- Coal 6 t, cured leaf 3,000 kg
- Coal CO2 from tonnes x NCV x the IPCC factor, then divided by 3,000 kg
