GHG emissions from the value chain

In addition to managing emissions from our operations, we track GHG emissions from our suppliers and products, classified as Scope 3 emissions. Considering the nature of our segments, emissions related to the use and processing of our products make up the most relevant categories in our value chain.

To calculate the most relevant Scope 3 emissions, we used two categories of the GHG Protocol: indirect emissions from product processing (Category 10) and indirect emissions related to the use of products delivered to the market (Category 11). These emissions are also included in the third party verification process for our inventory. Our direct emissions (Scope 1 and 2) in 2022 corresponded to around 10% of the total value chain, considering the two categories included in our Scope 3.

We joined the CDP Supply Chain initiative in 2022 with the objective of mapping the emissions of a sample of our main suppliers, selected based on criteria of financial representativeness and critical role for our operations. In this first year, there was the effective participation of more than 240 suppliers, who shared information about their GHG emissions, and of these, 68% reported using some climate scenario in their business strategy, 50% reported that they have an active goal and 48 % claimed to use renewable energy.

We were recognized for leadership in engaging suppliers in sustainable practices with an A- rating in the CDP assessment called Supplier Engagement Rating.

In 2023, we will carry out the second cycle of the CDP Supply Chain on Climate Change, and we will also include the topic of Water Security, in order to monitor the Management of Water Resources in our supply chain. We provide a direct channel for our suppliers to indicate their interest in participating in the CDP Supply Chain through the electronic address: cc-suprimentosesg@petrobras.com.br.

Other significant atmospheric emissions

In addition to GHG emissions, in our inventory we also monitor emissions of other pollutants: sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOCs) and total hydrocarbons (HCT).

The concepts described for our GHG inventory, including the source-to-source methodology and operational control approach, as well as the use of SIGEA® software, also apply to the inventory of these pollutants. In addition, the annual third-party verification process also includes these emissions.
