In the last century, increasing carbon emissions have profoundly impacted efforts to mitigate climate change. Therefore, energy-intensive industries face pressure to diminish their carbon emissions. In this context, the shipbuilding industry stands out as a significant source of emissions due to its high energy consumption and raw material-based production processes. This article assesses the carbon footprint of a Turkish shipyard manufacturing tugboats, concentrating on Scope I, Scope II, and Scope III emissions as defined by the Greenhouse Gas (GHG) Protocol. Calculations utilized DEFRA 2023 emission coefficients to ascertain CO₂ equivalent emissions for each activity type. The shipyard's overall emissions comprise 55.68% Scope I, 16.81% Scope II, and 27.51% Scope III. The carbon footprint evaluation emphasizes the necessity of diminishing the carbon footprint and underscores the significance of prioritizing environmental sustainability. This study has explored strategies like the use of solar energy, the transition to electric vehicles, a hybrid work model, and the establishment of local supply networks. These strategies provide practical and sustainable approaches to mitigating the environmental impact of carbon emissions in the shipbuilding industry.
