    Every year, Suzano accounts for, has independent third-party audits performed, and publicly discloses the data resulting from the Greenhouse Gas (GHG) emissions from its operations. To this end, the company has an internal procedure in place that establishes how to survey and calculate emissions, considering Scopes 1 (direct emissions from Suzano’s operational control), Scope 2 (indirect emissions from the generation of electricity purchased from the national grid), and Scope 3 (indirect emissions from the value chain).

    Emissions are reported based on the operational control approach and include operations:


    • Upstream: the activities of upstream suppliers and the forest operation, such as silviculture, harvesting, maintenance, forest protection, road construction, waste management, fertilizer application, and wood logistics.
    • Industrial operation: the industrial operation, such as the production of paper, pulp, consumer goods, energy generation, recovery and utilities, waste management, health and safety, the operation of study and research centers, the administrative operation (related to restaurants, transportation of employees, building maintenance), and the purchase of electricity.
    • Downstream: the operations involving the transportation and distribution of products, including Distribution Centers (DCs), maritime, rail, and road transportation within Brazil and abroad.


    Suzano has a systematized model for collecting data (Scopes 1, 2 and 3) through digital and automated means (such as SAP), in addition to its internal controls and the collection and collaboration with suppliers for the consumption related to its operation.

    Considering the production chain as a whole, a large part of the company’s emissions are from stationary industrial operations and in operational and product distribution logistics (inbound – transportation, storage, and delivery of inputs into the company – and outbound – transportation, storage, and delivery of products to customers), and, along with stationary industrial operations, the transportation of products between ports (national and international) concentrate the largest volume of emissions.

    The methodologies for quantification, data collection and use of emission factors are selected based on the recommendations of the ABNT NBR ISO 14064-1 standard (ABNT, 2007). The following documents were also used to prepare the 2020 base inventory:


    • The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard, WRI & WBCSD (2004).
    • Guides, guidelines and calculation tools from the FGV’s Brazilian GHG Protocol Program (PBGHGP) (2021).
    • 2006 IPCC Guidelines for National Greenhouse Gas Inventories, IPCC (2006).
    • Calculation Tools for Estimating Greenhouse Gas Emissions from Pulp and Paper Mills, NCASI (2005).


    In accordance with the principles for conducting GHG inventories, whenever possible, measurement data and emission factors that are closer to the local reality were considered. Greenhouse gas emissions accounting is regularly verified/audited by an independent third party.
