Carbon emission from burning of woody biomass in the cook stoves can be calculated using following formula;
| Carbon emission from the non-renewable biomass woody biomass | = | Quantity of non-renewable biomass | X | Net calorific value of the non-renewable biomass | X | CO2 emission factor for the biomass fuel |
You can use following default values for the calculation;
For non-renewable biomass weight value, you can take exact weight of the biomass required for cooking stove for family level (5-6) people. This formula will give you exact results with minimum uncertainty level.
Sustainable development involves successful management of natural resources. Efficient use along with best conservation practices provides prolonged supply of natural resources to satisfy the changing needs of humans while maintaining and enhancing the quality of the environment. Rural population needs cost effective ways to manage their energy requirements and hence require positive attention towards new technology that can improve their lives. Improved Chullahs (Cooking stoves); Introduction of LPG in rural areas; improved biogas plants with community kitchen; use of renewable energy devices like solar cookers and geysers etc. can provide an efficient solution. Many organizations are continuously developing cooking stoves technology with a higher efficiency but their customer-reach in the rural market is still very low due to various factors. One thing is very clear that; driven by low incomes and the lack of access to alternative, modern fuels people from rural areas are still using traditional fuels.

an interesting article indeed! of course, with lots of things to reflect upon.
Thanks Carin....stay tuned with GCG for more information.
thanks for the post .. I have a question how to find Carbon emissions from other sources like charcoal, cowdung cake and crop residue ..
kindly send the procedure and emission factors..
Thanks for your comment. The methodology is similar as mentioned in this post to calculate GHG emission from charcoal and cow dung. You just need to take NCV and emission factor (For combustion) and Methane emission potential of cow dung if left on the open pit to get decay anaerobically. IPCC website has all list of GHG emission factors. Please visit IPCC website for the same. Meanwhile we will write blog posts on the topic suggested by you. Stay tuned with us!
Thanks Sir for sharing....its very much helping for me..
for Quantity of non-renewable biomass do you simply substitute in the Kgs?? say I am using 4kgs of wood for cooking per day what will be the answer?
Hi, I guess, the unit of the biomass (here non renewable wood) would be in tonnes (1000 kg). This is due to the uniformity in the units of NCV value and CO2 emission factor. NCV value is on TJ/tonne and CO2 emission factor is in tCO2/TJ. Therefore, value of non renewable wood would be in tonnes.
This is really helpful. Thanks for sharing.
please tell me carbon emission factor for wood burning
