ABSTRACT: The civil construction industry consumes big quantities of water in all its productive chain, and facing the necessity to attend the sustainability agendas recommendations, it´s adjusting itself and taking responsibility in the market as a committed sector with matters related to the reduction of environmental impacts, this fact helps the grow of many evaluation methods. The goal of this work is to analyze some sustainable certification systems as BREEAM, CASBEE, LEED, SBTOOL, AQUA, Green Star and DGNB, to compare the purposes, evaluations and weights adopted in the criteria related to use and water management, considering the current environmental reality and, the hydro crisis, water scarcity and if the tools are consistent with the OSD in 2030 agenda. In the systems analyzed, water had a low importance and weight in opposition to other parameters such as CO2 emission and energy efficiency that had the major importance in most tools. Among the systems analyzed, the maximum weight related to the total of each tool was found in CASBEE (15%) and the lowest was DGNB (2,3%). The criteria in each sustainable certification system are specific to each country and they should have an international consensus that would result in environmental and financial gain.
