This paper aims to research the organizational factors influencing the implementation of energy efficiency measures in companies. The analysis was performed on a sample of companies from Serbia included in the World Bank Enterprise Survey. The raw data collected by the World Bank were utilized to analyze the correlation between various organizational factors and the adoption of energy efficiency measures. The analysis revealed a statistically significant correlation between management maturity and the implementation of energy efficiency measures in companies. These findings suggest that improving energy efficiency is not an isolated process but rather closely related to the maturity of management practices, highlighting the importance of comprehensive organizational development for achieving optimal energy management.

The study explored the legislative database for the maritime sector to be sustainable and have an intact blue economy. The problem for organizations with shipowners that have fishing boats older than 20 years is stated. Decision-making authorities face challenges nowadays. To be in the fleet for the next decade, shipowners for their ships should deploy energy efficiency projects for marine system retrofitting to improve energy efficiency and meet environmental regulations. The Ship Energy Efficiency Management Plan’s development principles are discussed due to the current need for its deployment from 2021, so shipowners can contribute to the fast adoption of new regulations by the International Maritime Organization. In this work it is being offered to incorporate energy management issues with guidelines for upcoming regulations as well as those that are currently enforced. To improve energy efficiency, reduce environmental impact and cut fuel consumption costs, marine system retrofitting has been proposed. In this paper the focus is being put on studying energy management strengths and weaknesses which can lead to a qualitative understanding of the performance of the organizational structure, this work also focuses on the management settings concerning energy efficiency. If the organization wants to win by integrating energy policy, high-quality communication or promotion of energy efficiency issues should be employed. Marine plastic debris challenges fishing carriers on the African Union route. A possible beneficial solution for shipowners is discussed in this study.

All European Union (EU) member states till 2020 had an obligatory target for energy efficiency. One of instruments for countries to achieve national energy efficiency goals is obligation for large companies (LC) and large electricity consumers (LEC) to implement certified energy management system or perform energy audit. In this study the Latvian case study of obligation for LC and LEC where examined. The analysis was carried out using a theory-based policy analysis method combined with evaluation criteria from the EU legislative assessment guidelines The Better Regulation Agenda – efficiency, effectiveness, relevance, coherence, added value, validity, complementarity, coordination, equality, sustainability and acceptability. To evaluate energy efficiency policy measures, it is also important to understand energy efficiency measures that will realistically meet the set company and national targets. AHP and TOPSIS analyzes were performed to evaluate these measures not only from energy efficiency but also from environmental, climate, engineering-technical, economic, and social aspects. The results allow us to assess the fate of existing policies and to draw conclusions on the improvements needed to meet energy efficiency and climate goals in the future. [ABSTRACT FROM AUTHOR]
