The aim of this study was to perform a rigorous field evaluation of alternative cooking fuel during actual use. Chabon Vet (green charcoal) fuel briquettes are produced by Carbon Roots International (CRI) in Cap Haïtien, Haiti and are made from carbonized agricultural waste, predominantly sugarcane bagasse. During this study Chabon Vet was compared to other commonly used wood-derived fuels (wood charcoal and firewood).
