This paper aims to present a brief review of sources of information for studying the variability of embodied carbon emissions in structural wood products commonly used in construction. The review considered 13 primary sources, focused on EPDs and generic databases, and allowed the collection of data for the study of 140 products divided into Sawn lumber, Glulam, OSB, and Plywood. The information collected made it possible to identify factors such as the variability of density properties, wood species, the origin of the products, among others. In addition to analyzing the variations in the biogenic carbon of the different products studied. The results allow us to conclude that although the variability of wood products can be significant, like any product of natural origin, when they are studied within the framework of the analysis of the materials of a building, they can present a smaller fluctuation than other materials such as concrete. Moreover, this effect can be accentuated in wood products with greater density or have undergone processes that increase the mass of biogenic carbon per cubic meter in the final product.
