TECHNICAL PROGRAMME | Energy Leadership
The engagement approach consists of four pillars: identification and classification of suppliers, awareness raising, monitoring, and incentives for emissions reduction. Suppliers representing approximately 80% of annual expenditures and/or with high ESG impact potential were considered. Based on references such as CDP, GHG Protocol, and Business and Human Rights – Access to Remedy, 233 “relevant” suppliers were mapped.
In its 2025–2029 Business Plan, Petrobras set a target for 70% of these suppliers to publish greenhouse gas (GHG) inventories, prioritizing quality data and strengthening climate engagement. This process is supported by the ESG Journey for Suppliers, a platform open to the external public, which has already reached more than 500 companies with monthly training, courses, and ongoing support. At the same time, Petrobras' ESG Questionnaire — also open to suppliers and non-suppliers — has received around 900 responses since 2023, of which 36% reported formalized climate commitments.
To encourage outstanding practices, the Best Suppliers Award included the category “Decarbonization,” recognizing efforts in measuring and reducing emissions, using renewable energy, and logistical and technological innovations. A multi-sector ESG Community of Practice was also created, bringing together companies that together represent more than 8% of the national GDP, with the aim of accelerating learning and generating joint solutions.
In the 2024 cycle of the CDP Supply Chain, 400 suppliers were invited—including the 233 relevant ones—and 245 responded, with 92% reporting Scope 1 and 2 emissions and 76% also reporting Scope 3 emissions. In addition, Petrobras promotes monthly live streams, preparatory webinars, and regional technical support, expanding training opportunities.
In the methodological field, the Company improved its Scope 3 inventory, detailing Categories 1 (purchased goods and services) and 2 (capital goods), following IPIECA guidelines and EPA factors (CO₂ emission intensity/US$). In the base year of 2023, the estimate totaled 6 MtCO₂e, with 19% in consumer goods, 22% in services, and 59% in capital goods. This refinement made it possible to identify more intensive segments—such as steel derivatives, chemicals, catalysts, and EPC services—directing actions to suppliers with greater impact.
Thus, Petrobras reaffirms that engagement, training, technical support, and recognition are essential pillars for accelerating the decarbonization of its supply chain and contributing to a low-carbon future.
