As global climate change impacts become more apparent, countries are implementing various policies to achieve carbon neutrality that can be categorized into direct regulations and market-based indirect regulations. The latter, utilizing economic incentives, is considered more efficient in transforming corporate behavior and promoting voluntary efforts for carbon reduction. In alignment with international trends, South Korea has introduced the Emission Trading System (ETS) in 2015. Despite this, the domestic carbon market remains underdeveloped, with low ETS participation, particularly in the aquaculture sector. In order to activate external projects under the ETS, this study proposes short-term strategies including linking ETS with popular eco-friendly energy distribution projects, developing standardized monitoring techniques, and integrating carbon reduction initiatives with other support mechanisms such as direct payment programs. Long-term strategies focus on developing new methodologies for external projects, promoting the use of renewable energy, and enhancing technologies to reduce energy consumption in aquaculture operations. By implementing these strategies, the study aims to enhance the participation of the aquaculture sector in carbon reduction efforts, contributing to the overall goal of carbon neutrality.
