Design/methodology/approach: The study used an empirical research, gathering economic data from investments in renewable energy sources in the Regional Units of Thessaloniki, Imathia and Pella. Data was collected through a structured questionnaire, administered with personal interviews with investors, by applying a simple random sampling method through a population-total number of investors retrieved from the Ministry of Environment, Energy, and Climate Change records. Findings: The results demonstrate that investments in renewable energy projects are sustainable and highly efficient on a case-by-case basis. The main criterion for accepting an investment element in a specific renewable energy technology application is the calculation of the Internal Rate of Return. The optimal investment pertains to photovoltaic system installations. Among the investments, hydroelectric and wind investments are also enticing. Investments in wind energy have the highest net present value, followed by investments in photovoltaic and hydroelectric systems. Concerning the profitability index, it is observed that investments in photovoltaic systems have a higher profitability index, followed by investments in wind and hydroelectric systems. As far as social characteristics are concerned, the majority of investors, regardless of their profession, invest in photovoltaics. Freelancers predominantly invest in wind energy projects, while employees mainly invest in hydroelectric projects. Research limitations/implications: The main limitation of the survey is related to the sample, which consisted of investors from three regional areas of Greece. A future study may be conducted to a larger sample, from all Greek regional units and examine possible differences in the results related to geographical area and profile of the investors. Originality/value: From the literature review, it is found that there is a lack of a comprehensive scientific method for evaluating the optimal investment choice in the renewable energy sector, leaving potential investors without a reliable framework for assessment of investment proposals. The current study can serve as a tool for investors in the renewable energy sector, assessing whether an investment yields financial gains compared to the capital allocated and therefore providing a tool to investors to know in advance the benefit of their potential investment.

The aim of this study is to explore environmental knowledge on Climate Change and the possibility for teachers to take action to protect the Environment. For this reason, a quantitative survey was carried out among preschool teachers of the Primary Education of Eastern Thessaloniki, through a structured questionnaire. The results of the research pointed out that the environmental knowledge of the Educators regarding the anthropogenic causes of climate change and the harmful effects of the phenomenon is a motivation for taking actions and at the same time encouraging sustainable practices among students for the protection of the environment.

Environmental, Social and Governance (ESG) activities into their decision-making processes. Our study makes use of ESG's environmental component to study the impact of environmental criteria on the annual turnover of the Greek food sector. According to the results, the food industries that have over 500 million annual turn over, invest in ESG and emphasize in environmental criteria. Investing in environmental policies and strategies increases financial sustainability. Companies become more profitable and efficient in this context.

A financial ratio analysis can be used as a starting point when assessing and improving a farm’s economic sustainability. The objective of the present article is to (1) provide insight into the financial ratios commonly used for pig farm assessments and (2) how they may be applied through an advisory tool to assess farm economic sustainability. Moreover, in this study, different financial ratios were examined to uncover trade-offs and synergies between them. Using the Farm Accountancy Data Network (FADN), we analyzed Spearman correlations between financial ratios. The correlation between these sets of indicators suggested that they could be used to estimate dairy farm economic sustainability. Our results showed that pig farms face a financial situation that can be improved. Pig farmers c...

Despite the high productivity and high quality of products, the goat industry shows low competitiveness due to high production costs compared to other EU countries. For economic sustainability, farms have to be profitable; therefore, it is important to maximize income whilst controlling costs. The aim of this paper is to identify the strengths and weaknesses of the goat breeding industry so that it is not only viable but also competitive. The economic performance of goat farms are evaluated in this study, as well as the factors that influence financial results. Capital formation and production costs composition of the holdings are examined. Moreover, the purpose of the analysis is to draw conclusions regarding the gross return achieved, the participation of production factors (land, labor, capital) in the composition of total costs...

Τα τελευταία χρόνια ωστόσο, ο αριθμός των ζώων και η μέση παραγωγή έχουν μειωθεί. Οι ρυθμοί επιχειρηματικής εξέλιξης του κλάδου είναι μικροί με συνέπεια τη μειωμένη ανταγωνιστικότητα και βιωσιμότητά του. Σκοπός της έρευνας είναι η διερεύνηση των παραγόντων που επηρεάζουν την παραγωγικότητα, την βιωσιμότητα και την ανταγωνιστικότητα του κλάδου και συμβάλουν στην επιχειρηματική προοπτική και ανάπτυξή του. Για τις ανάγκες της έρευνας χρησιμοποιήθηκαν οικονομικά δεδομένα από 120 αιγοτροφικές εκμεταλλεύσεις επιχειρηματικού τύπου, τα οποία συγκεντρώθηκαν με τη χρήση κατάλληλα δομημένου ερωτηματολογίου, έπειτα από προσωπικές συνεντεύξεις με τους κτηνοτρόφους-αρχηγούς των εκμεταλλεύσεων.
