In order to know the impact of future quotes of methane in the Azorean dairy milk farms, a decision model is built to the Azorean intensive grazing system of dairy farms. Some scenarios of methane levels reductions from 10 to 75% are considered and their impact is evaluated upon dairy farms income, level of CO2-eq emissions and intensity level of grazing system. The results have shown that any reduction of the methane level always implies a consequent decrease in income. If the CO2-eq has to be limited than there is the need to find alternative income activities for farmers in order to preserve economic sustainability. %K Climate Change %K Dairy %K Economic Sustainability %K Greenhouse Gas Emissions %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=64851
