Increasing energy efficiency is included in the UN Sustainable Development Goals (SDGs) to be achieved by the year 2030. Enhancing energy efficiency is also one of the priority areas for improving the operational efficiency of any oil production enterprise. The energy management system of enterprises has been founded and implemented on the basis of the international standard ISO 50001:2018 and it works successfully. The energy efficiency strategy is formulated in the energy policy and integrated into the business model of the companies. Companies receive significant energy savings in the exploration and production segments through technical, technological, and organizational measures. This article shows the main directions for improving the energy efficiency of the artificial lift well stock and the results of their implementation. The main constraints on the implementation of the energy efficiency policy of oil-producing enterprises have been identified and directions for improvement of energy-saving structure have been proposed. The article proposes strategic-level classification of energy-saving measures, which is based on assessment and comparison of implementation costs, payback period, and takes into account investments into artificial lift technology, therefore allowing investment priorities in the energy management sphere to be distinguished. Advanced directions for investment in oil-production technology have been identified, and an algorithm of development and implementation of key indicators of energy consumption efficiency has been proposed.

A city based on the sustainable development priorities, friendly to its residents, combines human activity, technology challenges, and environmental requirements. The implementation of the idea of smart city should be discussed with regard to specific areas of activity. In order to identify the way of perceiving the activity conducted under this concept, a survey was carried out among employees of the City Office in Zabrze. The cognitive, competence and informational scope was verified. It was found that the overwhelming majority of officials (79%) are convinced that smart city principles are being implemented. The survey participants also provided specific examples of smart-city initiatives undertaken in the city, and a significant part of the respondents (64%) assigned their professional tasks to them. Moreover, three out of four surveyed officials in Zabrze declared that they know the tools supporting the smart urban development. The results presented in the article constitute pilot studies aimed at understanding the extent to which the Smart City idea is known by local government administration employees. In addition, these results serve as a tool for the authorities of Zabrze to disseminate knowledge about smart city among employees of the city hall.

Many innovative environmental technologies never reach the market because they are new and cannot demonstrate a successful track record of previous applications. This fact is a serious obstacle on their way to the market. Lack of credible data on the performance of a technology causes mistrust of investors in innovations, especially from public sector, who seek effective solutions however without compromising the technical and financial risks associated with their implementation. Environmental technology verification (ETV) offers a credible, robust and transparent process that results in a third party confirmation of the claims made by the providers about the performance of the novel environmental technologies. Verifications of performance are supported by high quality, independent test data. In that way ETV as a tool helps establish vendor credibility and buyer confidence. Several countries across the world have implemented ETV in the form of national or regional programmes. ETV in the European Union was implemented as a voluntary scheme if a form of a pilot programme. The European Commission launched the Environmental Technology Pilot Programme of the European Union (EU ETV) in 2011. The paper describes the European model of ETV set up and put to operation under the Pilot Programme of Environmental Technologies Verification of the European Union. The goal, objectives, technological scope, involved entities are presented. An attempt has been made to summarise the results of the EU ETV scheme performance available for the period of 2012 when the programme has become fully operational until the first half of 2016. The study was aimed at analysing the overall organisation and efficiency of the EU ETV Pilot Programme. The study was based on the analysis of the documents the operation of the EU ETV system. For this purpose, a relevant statistical analysis of the data on the performance of the EU ETV system provided by the European Commission was carried out.

This article presents the issues of quality research and improvement of logistics processes in the area of distribution of one of selected industrial enterprises. The case described concerns the producer of raw chemical materials, who acts as a supplier for industrial customers. The studied company, due to dynamic changes in product demand, very often outsources the distribution of raw materials to external transport companies. This solution results in limited supervision over commissioned processes, which may lead to increased probability of customer dissatisfaction. The article presents the results of the study of the quality of logistic processes implemented or commissioned in the examined enterprise. The assessment was based on the results of the customer satisfaction survey and the results of the analysis of received complaints regarding deliveries. Analysis of the causes of complaints allowed to identify the actions necessary to improve the quality of logistics processes. This article contains, among others, the criteria for the assessment of transport service providers and a set of recommendations to reduce the risks associated with logistics processes of deliveries.
