Suzano's direct emissions (scope 1) are mainly related to the consumption of fossil fuels in stationary equipment at the industrial units and fuels used in vehicles at the forestry units.
In 2024, two new units joined the Suzano operation, Ribas do Rio Pardo in Mato Grosso do Sul, and in Suzano Packaging in the United States of America. The start-up of our Cerrado Project in Ribas and the incorporation of our first international plant led to a 5% increase in our Scope 1 emissions. It is important to note that, following the GHG Protocol, all the emissions from the North American operation in 2024 were accounted for within the Suzano group, and not just the emissions after its incorporation on October 1, and were also considered retroactively in 2022 and 2023, according to supplementary note 2.
Emissions from the stationary combustion category, which are related to generating electricity, heat, and steam and represent 72% of scope 1, increased by 6.9%. This increase is directly linked to Suzano's new units.
In the mobile category, which represents 21% of scope 1, we had an increase in emissions, mainly due to the start-up of the Ribas operation, which generates a greater demand for wood, mainly from harvesting and logistics, within our operations. In the category of agricultural emissions, which account for 7% of scope 1, waste, which account for 1%, and fugitive emissions, which account for 1%, there was a reduction in emissions due to the lower planting volume and stabilization of the forestry base.
The negative emissions from industrial processes are related to the emissions recovered in the calcium carbonate (CaCO₃) precipitation plants, or PCC, which contributed to the reduction of emissions in the scope discussed here, since in industrial processes, there is the consumption of carbon dioxide (CO₂) in the PCC. In physical-chemical processing, removals occur due to the CaCO₃ precipitation process, an input used in the industrial process, meaning that CO₂ is consumed in the PCC. The reduction in this category was due to the decrease in CO₂ exports by Suzano's factories.
Effluent emissions were not reported in 2024, as the aerobic treatment of effluents in pulp mills generates little methane emissions and is not considered by the methodology.

- Suzano's GHG emissions are reported using the operational control approach. Using the operational approach in our inventory gives us a clear view of our impacts and responsibility. In addition, this approach will enable us to work on targets and metrics in the areas where we operate, implementing effective mitigation strategies. Suzano applies the GHG Protocol methodology to calculate and present the GHG emissions of each subsidiary for the entire year reported, regardless of the time of financial incorporation;
- The base year of 2015 was chosen for the Paris Agreement. It aims to map the impact of emission reduction projects on the main operational fronts, as well as internal management and governance processes to leverage the approval of these projects and include carbon in the company's decision-making. We revised the methods for calculating the GHG Inventory following the methodology of the GHG Protocol and ISO 14.064. These changes led to the alteration of the results of scopes 1 and 2 in the base year (2015) and in the years 2022 and 2023, as well as the result for 2024. This revision was based on continuous improvements and methodological enhancements, such as updating the GWP indices referring to the IPCC's Fifth Assessment Report (AR5), enhancements to emission factors for scope 1 sources, and expanding the accounting of scope 3 material and applicable categories;
- The selection of methodologies for quantification, data collection, and the use of emission factors is based on the recommendations of the ABNT NBR ISO 14064-1 standard (ABNT, 2007). The following methodological references were also used to prepare the 2024 base year inventory:
- The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard, do World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) (2004);
- Guides, guidelines and calculation tools from the Getulio Vargas Foundation's Brazilian GHG Protocol Program (PBGHGP for its Portuguese acronym) (2023);
- IPCC Guidelines for National Greenhouse Gas Inventories, from the Intergovernmental Panel on Climate Change (IPCC, 2006);
- Calculation Tools for Estimating Greenhouse Gas Emissions from Pulp and Paper Mills, do National Council for Air and Stream Improvement (NCASI – 2005).
Following the principles for carrying out GHG inventories, measurement data and emission factors closest to the local reality were considered whenever possible. We try to avoid using assumptions and secondary data, emphasizing primary data from our operations, which allows us to have accurate and reliable monitoring of the company's decarbonization practices. The GHG emissions accounting for the Greenhouse Gas Emissions Inventory published in the Brazilian GHG Protocol Program Public Register is regularly verified/audited by an independent third party.
4. Scope 1 emissions are defined and calculated according to the methodology contained in The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (GHG Protocol), Revised Edition, March 2004, published by the World Resources Institute and the World Business Council on Sustainable Development (WRI/WBCSD).
