Fuel consumption data—mostly obtained by Suzano in an automated way—were converted into energy consumption based on the basic density and lower heating value of each fuel. In this sense, when available, the data contained in the technical specification sheet of the fuel used were adopted. When not available, the values presented by the National Energy Balance (MME, 2019) were used.
In 2020, an increase in energy consumption was registered due to increased production at our industrial plants. Even so, there was a reduction in the consumption of fossil fuels (mainly natural gas) by stationary equipment in the units, since the higher production in the industrial plants prioritizes the use of renewable sources (black liquor and renewable methanol available for combustion). In our logistics operations, there was also a lower consumption of gasoline, replaced with ethanol and ethanol added to gasoline.
