The escalating impact of anthropogenic activities on global climate patterns necessitates urgent measures to reduce emissions, with the maritime industry playing a pivotal role. This article aims examine adoption International Maritime Organization energy efficiency for often-overlooked fishing vessels and their contribution overall decarbonization efforts. analyzes attained technical indices case study large-scale vessel compares them those two cargo ships where IMO already apply. To support proposal, comprehensive analysis eight large purse seine is also presented. results show that 400 GT above could be subject measures. operational challenges, unique sector, suggest sector-specific considerations may required integrate fleet into existing guidelines. Looking ahead, this explores benefits aligning Regulation (EU) 2023/957 guidelines, as well applying Carbon Intensity Indicator (CII) in assessing environmental operations, emphasizing importance including these current regulatory frameworks promote decarbonization.

This study measured emissions from 76 oil tankers at Eastern Black Sea petroleum terminals to determine their emission factors. Emissions of CO, CO2, NOX, and SO2 were during cruise (C), maneuvering (M), hotelling (H) activities main engines (ME) auxiliary (AE). Using an activity-based approach, factors calculated the collected data. Real-time data 2013 2021 utilized total for each year, while regression analysis forecasted until 2040 under various scenarios. Weighted ME determined as 1.1 ± 0.22 g/kWh 654 13 13.95 2.75 11.45± SO2, AE, 0.21 706 15 15.3 1.4 11.15 2.25 g/kWh. Average load follows: C (ME): 67%, (AE): 35%, M 34%, 53%, H 76%, 62%. Total in 2022 projected be 235 tons 151580 3018 2251 SO2. Future scenarios indicate these amounts could increase by 3, 5, 12 times optimistic, normal, pessimistic scenarios, respectively.

Abstract International shipping conveys over 80% of global trade by volume and emits an estimated 3% the world's greenhouse gases (GHGs). There are many potential pathways barriers to decarbonizing diverse fragmented international sector, with numerous uncertainties. Here, we employ expert elicitation, gathering perspectives from 149 world‐leading experts in maritime decarbonization, characterize uncertainties decarbonization pathways. These predict a 30%–40% (25th–75th percentile range) carbon intensity reduction 2030 compared 2008, meeting Maritime Organization's (IMO) target. By 2050, they anticipate approximate 40%–75% cut GHG emissions, falling short IMO's 2050 net‐zero goal. Responding see occurring through three types measures: operational, technological, alternative energy sources. In short‐term, is predicted be dominated operational measures, while long‐term, it will energy, although there no consensus on which fuels dominate. Technological upgrades expected play crucial supporting roles. The believe that differences business models governance may lead different ship segment. experts' qualitative responses highlight: systems, fleet turnover, spillover effects other sectors, reducing industry pessimism, supply chain as critical leverage points can propel toward sustainable Navigating this transition demands support key levers identified study: politics policy, governance, contractual architecture.

Excessive CO 2 emissions and increased total costs of liner shipping are the two main problems affecting environmental economic benefits companies under European Union Emission Trading System (EU ETS). To address upcoming EU ETS, we propose a carbon cost accounting model for that accurately calculates shipping. We conduct case study containership operates on route from Far East to Northwest Europe. The results show sailing stage plays pivotal role in shipping, 94.70% emissions. Among four types fuel, using MGO is largest, while methanol smallest. Methanol, as an alternative proves be better choice than LNG control relationship between speed follows U-shaped curve selected containership. Notably, reduction effective only when exceeds 8.29 knots. Under key variable Speed may not always cost-effective. When keeping unchanged, should reduced allowance (EUA) price rises within certain range. For HFO, most economical knots, corresponding increase EUA 304.95% 261.21%, respectively. If continues rise, will become ineffective controlling This can enhance companies, meet compliance requirements provide new perspective

Abstract The International Maritime Organization (IMO) aims to reduce greenhouse gas (GHG) emissions by 40% 2030 compared with 2008. carbon intensity indicator (CII) calculates the annual reduction factor required continuously improve a ship's operational at specific rating level. Verification and documentation of achieved CII against prescribed target are necessary establish rating. This study focuses on intricate process data collection for within oil shipping industry, targeting engineering departments shipboard management teams. Against backdrop industry's substantial dioxide emissions, IMO has mandated calculation values ships exceeding 5000 gross tons promote sustainability environmental impact. We have collected emission 20 tankers over period 2 years using our ship maintenance operating system (SMOS) analyzed compare ratings. Our results indicate that staggering ~63% vessels had lowest category E. It is therefore crucial properly collect, organize, evaluate take measures paper provides deeper insight into evolving methodology, emphasizing incorporation correction factors exclusions, delineates essential practices needed facilitate accurate calculations.
