Suzano's main direct emissions (Scope 1) are related to fossil fuel consumption in stationary equipment at the Industrial Units, as well as fuels used in vehicles at Forestry Units.

In 2022, emissions in the stationary combustion category (which represents 72% of Scope 1), decreased significantly, with a 7% reduction. In the mobile category (which represents 20% of Scope 1), there was an increase in emissions in all forestry business units as a result of operational control transfer in some representative activities, such as wood transportation. The agricultural emissions category (representing 8% of Scope 1), waste (representing 1.47%) and fugitive emissions (representing 0.39%) showed an increase in emissions due to higher volume of forestry operations and base expansion, mainly in Mato Grosso do Sul State.

Negative emissions from industrial processes are related to recovered emissions in the PCC plants (Precipitation of Calcium Carbonate), which contributed to reducing emissions from this scope, given that, in industrial processes, there is CO₂ consumption in the precipitation of Calcium Carbonate (CaCO₃). Effluent emissions are not reported in 2022 as aerobic treatment of effluents in pulp mills generates low methane emissions and is not accounted for by the methodology.

Regarding type of emissions, there was an absolute emission reduction in electricity, heat and steam generation due to the modernization process and deactivation of obsolete resources in our older plants. In physical-chemical processing, there were removals resulting from the precipitation process of calcium carbonate (CaCO₃), an input used in the industrial process. This indicator's reduction is in step with the reduction in electricity, heat, and steam generation, as it is a sub-process of these units. Meanwhile, material, product, waste, employees and passengers’ transportation increased, mainly due to greater operation and primarization of services in Forestry Units.

Data were also calculated using the IPCC Fifth Report (AR5) metrics for the Greenhouse Gas Emissions Inventory to be released in the Public Registry of the Brazilian GHG Protocol Program and can also be made available upon request.
