I hate to tell you this; but use of natural gas, propane, or electricity (from an efficient coal-fired powerplant) is way, way less pollutive than burning wood or wood pellets to cook. Not to mention the health concerns of cooking over wood on a daily basis. When you burn wood or pellets you produce particulate matter and carbon monoxide; in addition to the CO2. I would switch over to mulching or composting your stove fuel.
