GHG Emissions Intensity in Maritime Transport

In the maritime transport segment, we monitor the greenhouse gas emissions of the contracted fleet and improve metrics to monitor the performance in terms of emissions intensity in maritime transport in long-haul and cabotage operations, following the new guidelines of the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO).

Beginning in 2023, we will also start monitoring our GHG Emissions Intensity in Maritime Transport per ton transported x mile and our GHG Emissions Intensity in Maritime Transport per cargo capacity x mile.

Among the actions implemented in 2022 to improve logistical and operational performance with a carbon efficiency bias, we highlight the following:

> Speed management: We achieved around 70% of trips operating at optimal speed, with lower emissions, and meeting the logistical deadlines agreed upon with our customers.

> Route optimization based on meteoceanographic conditions: choosing the best navigation route for long distances considering the weather conditions brought gains of around 1% in consumption and, consequently, a reduction in emissions compared to the forecast contractual consumption.

> Choice of ships for coastal navigation or long-haul navigation based on consumption: more efficient ships with lower consumption are prioritized for long-distance schedules (long haul).

In addition to operational actions, we implemented changes in the vessel hiring process to hire vessels with better consumption performance and, consequently, lower greenhouse gas emissions.

Main vectors:

> Start-up of new FPSOs using CCUS-EOR technology

> Confirmation of the E&P reinjection volume in the main assets: Tupi, Mero, and Búzios.

We ended 2022 with 37 Eco Type ships. Eco Type is a term used by the market to identify vessels built from 2015 onwards, with improved construction designs to comply with the energy efficiency improvement measures established by the International Maritime Organization (IMO), aimed at reducing fuel consumption and greenhouse gas emissions. The main difference lies in the technologies applied in the construction of these ships, with additional equipment to the hull and engines developed to assist in energy efficiency, as well as improved design that reduces vessels’ weight and water resistance. Due to the modern technologies used and lower fuel consumption, the rental value of Eco Type ships is generally higher than that of a conventional vessel. Therefore, we have reserved part of our Decarbonization Fund budget to support this initiative.

In 2022, we carried out improvements on our Transpetro fleet ships dedicated to longhaul routes, such as painting with high-performance paint during ship docking and modifying vessels with the addition of hull appendages and propellers that improve the hydrodynamic profile. We estimate that those improvements can provide a reduction of approximately 4% in fuel consumption and, consequently, in GHG emissions.
