There are currently four Emission Control Areas (ECAs). These ECAs cover North America, the US Caribbean Sea Areas, the North Sea, and the Baltic Sea. From 1 January 2015, ships have been required to use fuel with a 0.1% Sulphur content limit while operating in these ECAs.

Emission Control Areas (ECA) are defined under MARPOL Annex VI as areas where the adoption of special mandatory measures to regulate emissions from ships is required to prevent, reduce and control air pollution from NOX and/or SOX and/or particulate matter (PM) and their attendant adverse impacts on human health and the environment.

Emission control areas (ECAs), or sulfur emission control areas (SECAs), are sea areas in which stricter controls were established to minimize airborne emissions from ships as defined by Annex VI [1] of the 1997 MARPOL Protocol.

On the 10th of December 2021, at COP 22 of the Barcelona Convention in Antalya, Türkiye, 22 signatory governments agreed to establish in Mediterranean Sea a sulphur emission control area (SECA) for shipping, under MARPOL (Annex VI), with the proposal to be submitted for adoption to MEPC 78 in June 2022..

In the United States, Emission Controlled Areas (ECAs) are established to regulate air pollution from ships, particularly in coastal and inland waterways. The primary ECA in the U.S. is the …

2024年4月9日 · Emission Control Areas (ECAs) and Sulphur Emission Control Areas (SECAs) have emerged as crucial regulatory mechanisms to address this issue. By limiting the emissions of harmful pollutants from ships, these designated areas aim to reduce air pollution, protect human health, and mitigate environmental damage.

2015年1月1日起在 MARPOL公约 附则VI规定的排放控制区域（简称SECA，下同）使用的燃油（指HFO、MGO、MDO）含硫量必须低于0.1%m/m。

2024年4月27日 · IMO 排放控制区要点总结: 2021年1月1日起船舶进入波罗的海、北海、北美洲和美国加勒比海域四个排放控制区ECA，均实施SECA+NECA，即船舶使用燃油的含硫量不得高0.10%m/m和满足第三阶段氮氧化物排放控制标准。

2024年1月26日 · 在2023年11月提交给IMO的一份文件（PPR 11/INF.4）中，美国环境保护署（EPA）得出结论，北美ECA实施的燃油硫控制导致了国际航运颗粒物排放的显著减少，而NO x排放减少的预期目标尚未实现。 由于Tier III 船舶更新缓慢，目前在北美ECA美国区运营的Tier III 主 …

2018年6月17日 · 排放控制区（Emission Control Area，简称ECA），可分为硫排放控制区（SECA）和氮排放控制区 (NECA)。 1、硫排放控制区 (SECA) SOx主要是燃料中的含硫的燃烧产物，以废气的形成排放于大气，尤其SO2容易氧化形成酸雨危害人类，主要是取决于柴油机所燃用燃料的含硫量。 2、氮排放控制区（NECA） NOx包括NO、NO2、N2O4等，其中对环境危害最大的是NO和NO2，高温、富氧和氮氧在高温环境中长时间停留，是柴油机燃烧过程促进NO生成 …
