If you are truly interested in this sort of thing, go to backpackinglight.com - Roger Caffin has tested various stoves over the years and written articles. One that I downloaded focused on carbon monoxide emissions. Interesting stuff. You have to buy the articles or get a membership - might be worth it if multiple articles are of interest to you.
