Navigating the Seas of Sustainability: A Study on Maritime Scope 3 Emissions Through Digital Innovation

Abstract

Abstract This case study provides a simplified overview of Scope 3 emissions within industry, focusing on a global offshore logistics provider. With total emissions from offshore logistics projected to increase by 250% by 2050 as per IMO, reducing emissions without impacting productivity and operational efficiency is a key challenge. The assessment used industry-standard methods and procedures and involved a thorough process of data collection and analysis. This includes leveraging industrial data to conduct preliminary analysis and estimations. The detailed calculations were also based on assumptions and emissions factors from various sources such as GHG Emissions Calculator, IEA, US EPA, ICCT, IMO, and ORR. The comprehensive assessment included emissions from its supply chain to end use of sold services. Categories include purchased goods and services, capital goods, fuel and energy-related activities, upstream transportation and distribution, waste generated in operations, business travel, employee commuting, upstream leased assets, downstream transportation and distribution, processing of sold products and use of sold products. The company found that its Scope 3 emissions accounted for a significant portion of its overall GHG footprint, and identified several key areas where emissions reduction efforts could be focused. These areas included optimizing shipping routes, improving the energy efficiency of its vessels, and collaborating with suppliers to reduce emissions across the supply chain. These optimizations combined can lead to significant reduction (12 – 25%) in environmental impact in long term along with savings in costs, time, and even potential application in other industrial operations. The findings of this study can assist entities to identify its major emission sources and develop strategies to reduce its carbon footprint. Our case study offers a simplified overview of Scope 3 emissions, with calculations for each category, aimed at enhancing understanding of emissions categories and calculations for Scope 3. The findings can benefit policymakers and regulators by highlighting areas where offshore logistics can focus their efforts to reduce their Scope 3 emissions.
