The wood burning stove provides a carbon friendly option of heating home using the fossil fuels. The wood burning generates carbon dioxide which is released in the environment. This carbon dioxide is absorbed by the trees in making food and thus the end result is zero carbon.

However along with carbon dioxide the wood produces a large quantity of soot, particles similar to that emitted by diesel cars. This has side effects like causing cancer in human beings along with breathing problems.

In some places like South America, Central America and Caribbean the Wood burning stoves are built inside the house without proper ventilation. The smoke released from the stove stays inside the house and the same is breathed by its inmates causing breathing problems and sometimes even cancer. Reports by the World Health Organisation say nearly 2 million people are killed each year due to indoor air pollution caused by open fire cooking. besides cutting of the large amount of trees for firewood also endangers the ecosystem causing unexpected changes in the atmosphere and natural calamities like hurricanes and cyclones.
