Sulfur Emission Control Areas (SECAs)

Sulfur Emission Control Areas (SECAs) are designated regions where ships must reduce sulfur oxide emissions from their engines to protect air quality. Ships operating in SECAs use cleaner fuel with lower sulfur content or install special equipment to limit sulfur emissions, helping to reduce air pollution, acid rain, and health risks in these sensitive areas. These zones are established by international agreements to promote cleaner maritime practices and environmental protection in busy ports and coastal regions.
