With its fast economic development, the energy requirement for the region has rapidly grown. As the region relies mainly on nonrenewable energy sources and is suffering from issues like pollution, the high cost of energy imports, depleting foreign reserves, etc. it is searching for those factors that can help enhance the renewable energy generation for the region.

The purpose of this paper is to explore the impact of technology management (TM) and its practices through process and maintenance technologies on sustainability performance (SP) for petroleum refineries and petrochemical companies in terms of economic, environmental and social sustainability.\u0000\u0000\u0000Design/methodology/approach\u0000A new proposed framework has been developed for a clearer understanding in relation to these aspects. The study was conducted among Egyptian refineries and petrochemical companies. A structured questionnaire was used to collect data from 65 petroleum experts and professionals, which was then summarized using statistical analysis, hypothesis testing and regression analysis.\u0000\u0000\u0000Findings\u0000The findings demonstrate that TM has a significant and direct impact on SP. Furthermore, the study shows that process technology (PT) has a positive influence on the three aspects of SP. Although maintenance technology has a positive impact on economic and environmental sustainability, it shows no direct effect on social sustainability.\u0000\u0000\u0000Research limitations/implications\u0000The degree to which TM and sustainability principles are implemented across petroleum companies in various countries varies significantly because of managerial and cultural dimensions. Therefore, when conducting the research, it is important to consider the study’s geographical area to comprehend how these practices are impacted by the distinctive managerial and cultural settings of each country. Also, respondents in developing countries do not participate in such surveys with much enthusiasm.\u0000\u0000\u0000Practical implications\u0000The study shows that implementing TM practices generates more economic stability and ensures environmental and social sustainability. The research studied how PT and maintenance practices affected each aspect of sustainability. These findings can apply to all downstream oil companies, regardless of their size or type of operations. Further research can be conducted to examine the relationship between variables in other industries.\u0000\u0000\u0000Social implications\u0000Decision-makers and managers may use the study's findings to improve their companies' performance and develop new plans and policies. The results demonstrate that companies will have a greater chance of achieving sustainable performance if they incorporate process and maintenance technologies into their activities. Besides economic and environmental sustainability, petroleum companies must strive for social sustainability.\u0000\u0000\u0000Originality/value\u0000The study is regarded as a significant contribution to the management of petroleum refineries and petrochemical companies, as it combined TM practices with SP in a single research framework.

On average, natural gas rent increases the sample’s growth rate by about 2.634% percentage points in the short run. The result indicates that the qualities of institutions (political and economic) have a significant positive long-term effect on the economies of the GECF. In addition, the study’s energy price volatility positively correlates with the countries’ growth.\u0000\u0000\u0000Research limitations/implications\u0000There might be a need to investigate the effects of natural gas rents and institutions as co-growth drivers in each country within the GECF. The likelihood exists that the impact of natural gas rents and institutions on economic growth at the country’s level may differ from the outcome of such an experiment on the group level. Because of space and time limitations, this study could not carry out the specific country’s investigation of natural gas rents and institutions as a co-growth driver. That limitation may constitute further study to advance this study to a new height.\u0000\u0000\u0000Practical implications\u0000With good institutions, natural gas rent is likely to be an alternative growth driver for some economies that rely on fossil fuels like oil as a growth driver. By extension, the GECF has the potential to rival Organisation of Petroleum Exporting Countries (OPEC) in the global energy market, particularly in achieving Sustainable Development Goal number seven. In essence, evidence in this study suggests that natural gas rent has long-term positive effects on the growth of the GECF, conditioned on good institutions. Moreover, the drive of global energy consumption towards sustainable energy usage is an economic blessing for the GECF. By extension, the demand for natural gas would continue to rise, creating opportunities to improve natural gas rents. By implication, the GECF would continue to benefit from the pursuit of sustainability as the world shifts towards energy consumption with less CO2.\u0000\u0000\u0000Originality/value\u0000Firstly, this study models the qualities of institutions for the GECF.

First, the generalizability of the findings is one of the common limitations of scientific research, and this study is not an exception.
