Echo patterns are similarity-based hypotheses, not proof of causation. Open the sources and evaluate the linkage yourself.

Evidence Scorecard

A single score cannot prove an echo. This card triangulates semantic, temporal, and linkage evidence.

Multilingual semantic similarity

Computed with intfloat/multilingual-e5-small multilingual embeddings. Display score is a calibrated mapping of the raw cross-lingual cosine (0.847); higher means closer meaning. Reflects semantic similarity, not proof of causation.

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; 2023 IMO MEPC 377(80) → 2018/2020 친환경선박법 + 2022 해양환경관리법 개정 + 2023 국제해운 탈탄소화 추진전략). Korean agency then adopted Korean text using the same policy vocabulary. Matched terms: "Carbon Intensity Indicator (CII)" ↔ "선박운항탄소집약도지수(CII)"; "Energy Efficiency Existing Ship Index (EEXI)" ↔ "선박에너지효율지수(EEXI)"; "MARPOL Annex VI" ↔ "해양환경관리법(MARPOL 부속서 VI 수용)".

The 2023 IMO GHG Strategy (resolution MEPC.377(80), adopted July 2023) sets indicative checkpoints to reduce total annual GHG emissions from international shipping by at least 20%, striving for 30%, by 2030, and by at least 70%, striving for 80%, by 2040, compared to 2008, and to reach net-zero by or around 2050. Short-term measures adopted at MEPC 76 (resolution MEPC.328(76)) amended MARPOL Annex VI with a technical Energy Efficiency Existing Ship Index (EEXI) and an operational Carbon Intensity Indicator (CII).

IMO · 2023 GHG Strategy (MEPC Resolution 377(80))

The 2023 IMO GHG Strategy (resolution MEPC.377(80), adopted July 2023) sets indicative checkpoints to reduce total annual GHG emissions from international shipping by at least 20%, striving for 30%, by 2030, and by at least 70%, striving for 80%, by 2040, compared to 2008, and to reach net-zero by or around 2050.

National Law Information Center · Marine Environment Management Act implementing rule (선박에서의 오염방지에 관한 규칙 · 해양수산부령 제620호)

Korea's Marine Environment Management Act (해양환경관리법) was amended to introduce the ship Energy Efficiency Existing Ship Index (EEXI, 제41조의5) and the operational Carbon Intensity Indicator (CII, 제41조의6), both inserted 2022-10-18, with the implementing rule detailed under 해양수산부령 제620호 (2023-09-01); the amendment's stated rationale is to reflect the revised 「1973년 선박으로부터의 오염방지를 위한 국제협약」 (MARPOL), explicitly citing the international convention.

Confidence — Editorial judgment, now shown as a confidence tier (A–D) based on semantic, temporal, and linkage evidence. Not proof of causation.

Echo Strength — Metadata completeness score. Rewards verified sources, paired links, explicit dates, keyword diversity, and origin tags.

Vocabulary Overlap — Heuristic score measuring shared tokens between global and Korean texts. Reflects loanwords and repeated terms, not meaning across languages.
