We present advances in a project aiming to reduce uncertainty in the Mexico City biogenic VOC emissions inventory. Work was carried out to obtain emission factors form dominant species under different climatic conditions. To focus further especiated measurements efforts, a ranking by measuring intensity of total emissions is being carried out on several relevant species. Uncertainty in national forestry inventory, a most important source of information is being assessed. Also, uncertainty on activity data will be reduced by measuring the leaf area index of disturbed and undisturbed forests of pine, abies and quercus in different sites in the Valley of Mexico. With these later data a perturbation index will be introduced into the emissions inventory equations.
