Echo Evidence Brief

Plain-language explanation for first-time readers — side-by-side echo comparison, verbatim primary-source excerpts, and X-discourse discovery context (not tier evidence).

IMO published the global instrument first (Global precedent precedes Korea; 2019–2021). 해양수산부 then adopted Korean text using the same policy vocabulary. Matched terms: "IMO 2020 sulphur cap" ↔ "IMO 2020 황 함량 기준"; "MARPOL Annex VI" ↔ "MARPOL 부속서 6"; "port ECA 0.1%" ↔ "항만 ECA 0.1%". Read the side-by-side comparison and verbatim primary-source excerpts below.

Agenda Arc

Curated

Global purpose, Korean purpose, and precursor stages. Reasoning echo is discourse observation — not proof of coordination.

Global purpose

Cut ship sulphur emissions in ports and seas via MARPOL Annex VI 0.50% global cap and emission-control area rules.

Korean purpose

「해양환경관리법」(2019.7.2 시행령 개정): 외항선 0.5%(2020.1.1), 내항선·어선 0.5%(2021.1.1). 연료유 황함량 초과 사용 시 1년 이하 징역 또는 1천만원 이하 벌금(제129조).
