Guidelines for Reducing the Greenhouse Gas Emissions of a Frozen Seafood Processing Factory Towards Carbon Neutrality Goals

This research aims to calculate the Carbon Footprint for Organization of a plant manufacturing frozen processed seafood and propose strategies to reduce greenhouse gas (GHG) emissions following the Net-Zero Pathway, using 2024 as the baseline year. The findings indicate that Scope 1 emissions amounted to 12,685 tons of CO2 eq, Scope 2 emissions totaled 15,403 tons of CO2eq, and Scope 3 emissions reached 31,564 tons of CO2eq, leading to a combined total of 59,652 tons of CO2eq across all scopes, with an additional 34,027 tons of CO2eq from other GHG sources. To achieve net-zero emissions by 2050, annual reductions of 3.46% per category are required. The short-term target for 2028f aims to reduce emissions to 10,929 tons of CO2eq for Scope 1, 13,270 tons of CO2eq for Scope 2, and 27,194 tons of CO2eq for Scope 3, resulting in total emissions of 51,392 tons of CO2eq. The proposed reduction strategies include optimizing Scope 1 emissions by preventing leaks in R507 refrigerant systems, replacing corroded pipelines, installing shut-off valves, and switching to low-GHG refrigerants. For Scope 2, measures focus on reducing electricity consumption through energy conservation initiatives, carrying out regular machinery maintenance, installing Variable Speed Drives (VSDs), upgrading to high-efficiency motors, and integrating renewable energy sources such as solar power. For Scope 3, emissions from raw material procurement can be minimized by sourcing from certified suppliers with established product carbon footprints, prioritizing carbon reduction labeling, and selecting nearby suppliers to reduce transportation-related emissions. These strategies will support the organization in achieving carbon neutrality and progressing toward the net-zero goal.
