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. The emissions specifically include SOx, NOx, ODSs and VOCs [2] and the regulations came into effect in May 2005.

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 North American ECA, which includes the waters off the U.S. and Canadian coasts.

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.

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..

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。 或者可能使用其他等效替代手段（如脱硫塔）。 IMO 4个ECA. 控制区范围：建议二副将排放限制区域必须清晰的标注在相关海域的海图上，并提前换油，进入限制区域。 欧洲ECA水域：North Sea (北海)62°N以南和004°W度以东、 …

2022年10月26日 · An Emission Control Area (ECA) is a sea area in which stricter controls to minimize airborne emissions from ships are established. Initially this regulation was aimed to reduce sulphur oxides (SOX) and is extended in 2005 to include nitrogen oxides (NOX) for several areas. ECAs with restrictions on SOX only are sometimes referred to as SECAs.

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 …
