This study deepens the comparison of carbon generation from data centers in Brazil and the United States in scopes 1, 2 and 3 of the GHG Protocol, normalizing the results per 1 MW of IT load and per year of operation. The methodology starts from a reference installation with PUE 1.4, equivalent to 12,264 MWh/year of total electricity per MW of IT, and applies location-based emission factors derived from the electrical matrix: for Brazil, the analysis uses the combined reading of official data from the Energy Information System/National Energy Balance, by EPE, and the operation of the National Interconnected System by ONS; for the United States, it uses the carbon intensity of the electricity sector reported by the International Energy Agency. In the central scenario, Brazilian scope 2 is estimated at around 0.638 ktCO₂e/MW TI.year, compared to approximately 4.55 ktCO₂e/MW TI.year in the United States. Scope 1 is minor but not negligible: tests and emergencies with diesel generators can range from about 11 to 94 tCO₂/MW TI.year for 12 to 100 hours of annual operation, before refrigerants. Scope 3 is addressed by life cycle criteria, including civil works, electromechanical infrastructure, servers, batteries, logistics, replacement and end of life, with an annualized range of 0.8 to 3.0 ktCO₂e/MW TI.year. It is concluded that Brazil has a robust structural advantage in location-based operational carbon, but the complete comparison requires transparency about PUE, temporal emission factor, actual operation of generators and scope 3 borders.
