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.

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 (ECAs) designated under regulation 14 of MARPOL Annex VI (SOx and particulate matter emission control) The Baltic Sea area (regulation 14.3.1 of MARPOL Annex VI and regulation 1.11.2 of MARPOL Annex I):

Learn how ECA, SECA, and DECA emission-controlled areas regulations differ and shape maritime practices and impact air quality worldwide

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.

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. [3] [4] Annex VI contains provisions for two sets of ...

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..

2022年10月22日 · The SECA zones (SECA for Sulphur Emission Control Area) are maritime areas in which strict controls of merchant ships have been established by the Intemational Martime Organization (IMO) to minimize emissions of sulfur oxides

在硫排放控制区（SECA）内，必须使用含硫量低于1.5%m/m的低硫燃油，或使用经认可的废气滤清系统或其它技术方法以保证船舶 硫氧化物 的总排出量不超过6.0 g/kWh。

2018年12月10日 · 通过设立船舶大气污染物排放控制区（以下简称排放控制 区），降低船舶硫氧化物、氮氧化物、颗粒物和挥发性有机物等大气污染物的排放，持续改善沿海和内河港口城市空气质量。 二、设立原则. （一）促进环境质量改善和航运经济协调发展。 （二）强化船舶大气污染物排放控制。 （三）遵守国际公约和我国法律标准要求。 （四）分步实施和先行先试并举。 三、适用对象. 本方案适用于在排放控制区内航行、停泊、作业的船舶。 四、排放控制区范围. 本方 …
