Korean Register Leads IMO Expert Groups on Ammonia Effluent and NOx Reduction
The Korean Register (KR) has taken a leading role in coordinating two expert groups under the International Maritime Organization (IMO) focused on marine environmental issues. These groups are tasked with managing ammonia effluent and addressing failures in nitrogen oxides (NOx) reduction strategies. As the maritime industry faces increasing pressure to reduce greenhouse gas emissions, ammonia-fueled vessels are being considered as a zero-carbon alternative. However, the high toxicity of ammonia and the lack of international management standards pose significant challenges. To address these, KR, in collaboration with the Ministry of Oceans and Fisheries (MOF) and major Korean shipbuilders, established a joint working group in 2025. This group has been instrumental in advancing the discussion on ammonia effluent management at the IMO's Pollution Prevention and Response (PPR) sessions. The expert group on ammonia effluent management, coordinated by KR's Senior Surveyor KIM Joonghun, held its first meeting in...
