即将出台的针对航运业硫氧化物和氮氧化物（NOX）排放的更严格的排放控制区（ECA）法规可以通过不同的策略来处理。在这项研究中，提出了三种符合 ECA 硫法规以及 Tier III 氮氧化物法规的替代方案，并使用生命周期评估进行了比较。与重燃油（HFO）相比，这三种替代品都不会显着降低生命周期对气候变化的影响。然而，所有替代方案都将减少对颗粒物、光化学臭氧形成、酸化和陆地富营养化潜力的影响。评估还强调了两个重要的监管方面。首先，需要调节使用选择性催化还原 (SCR) 造成的氨泄漏，其次需要调节 LNG 发动机的甲烷泄漏。此外，对瑞典水域 SCR 使用情况的分析表明，许多船舶已使用 SCR，已经显着减少了 NOX 排放。 (C) 2013 Elsevier Ltd. 保留所有权利。
The upcoming stricter emission control area (ECA) regulations on sulphur and nitrogen oxides (NOX) emissions from shipping can be handled by different strategies. In this study, three alternatives complying with the ECA regulations for sulphur as well as Tier III for NOX are presented and compared using life cycle assessment. None of the three alternatives will significantly reduce the life cycle impact on climate change compared to heavy fuel oil (HFO). However, all alternatives will reduce the impact on particulate matter, photochemical ozone formation, acidification and terrestrial eutrophication potential. The assessment also highlighted two important regulatory aspects. Firstly, the need to regulate the ammonia slip from use of selective catalytic reduction (SCR) and secondly the need to regulate the methane slip from LNG engines. In addition, an analysis of the use of SCR in Swedish waters is presented showing that SCRs have been used on a number of ships already giving significantly reduced NOX emissions.
