Popis: One of the main agricultural crops in Brazil is the tobacco (Nicotiana tabacum) production, currently the second largest producer of this commodity of the world. Its production extends across the three southern states of the country and accounts for important interactions with the environment. Thus, the study of the relationship between tobacco cultivation and the environment should be evaluated in order to reduce its impacts. This study uses a life cycle assessment (LCA) to evaluate the Carbon Footprint (CF) of Virginia (VA) and Burley (BU) tobacco varieties produced in southern Brazil, using the dataset of 14,409 tobacco farmers. The LCA results showed that the use of nitrogen fertilizer in the crop stages of both the tobacco varieties is the main contributor to greenhouse gas (GHG) emissions. The CF was 1398.5 kg CO2-eq/ton of dry VA tobacco, compared to the 1829.7 kg CO2-eq/ton of dry BU tobacco. The seedling and industrial processing stages of both tobacco varieties account for less than 13% of the overall CF.
