Abatement Cost of Greenhouse Gas Emissions Using Charcoal Cookstove in the Philippines

抄録

This paper showed the abatement cost and the amount of GHG emission reduction if charcoal cookstove is used instead of fossil fuel-based cookstove such as kerosene and LPG cookstoves. The abatement cost per tonne emission reduction is calculated as the net present value (NPV) of the incremental cost between the fossil-based and the charcoal cookstoves divided by the total emissions reduction. The incremental cost refers to the difference between the generation costs per GJ from the different energy systems. The abatement costs of using charcoal cookstove instead of LPG stove and charcoal cookstove instead of kerosene cookstove amount to PhP10,725.64/t-CO₂e and PhP5,149.9085/t-CO₂e reduction, respectively. However, the use of charcoal cookstove instead of kerosene cookstove and LPG cookstove will result to displacement of 4.9485 t-CO₂e and 2.6676 t-CO₂e for a period of five years, respectively. The shift from the use of kerosene and LPG cookstoves to charcoal cookstove would result to large reduction of GHG emission to the atmosphere knowing that cooking particularly in the residential sector consumes large amount of energy.Having obtained abatement cost values provides a concrete measure for assessing the potentials of biomass energy technologies in reducing hazardous emissions. Such information is useful for comparing different technologies and will help guide policy makers to decide on which technologies should be promoted for further development and deployment.
