Global warming has become a major concern for countries around the world. In this context, developed countries have decided to reduce global emissions to achieve sustainable development. The energy mix of OECD countries consists of 80% fossil fuels and accounts for about 35% of worldwide carbon emissions. Therefore, it is important to analyze how environmental factors affect carbon emissions in OECD countries. This study uses fossil energy, renewable energy (RE), and GDP for the period 1990–2019. Unlike previous studies, we will estimate two separate models for FFE and RE. To evaluate the empirical results, advanced panel data estimation methods using the cointegration test and the CS-ARDL estimation technique are employed to examine the long-run relationship between the variables. The results of the study demonstrate that fossil fuel use and GDP increase carbon emissions both in the short and long term. However, the use of RE hurts carbon emissions and is associated with sustainable development in OECD countries. Therefore, it is assumed that although fossil fuel use degrades the environment, economic growth helps it by reducing carbon emissions. Overall, our study shows that the use of RE is essential for OECD countries to achieve their environmental sustainability goals because it reduces the share of fossil fuels in the overall energy mix. Furthermore, in order to achieve a sustainable environment, OECD countries are recommended to begin long-term planning to reduce carbon emissions.

Corporate social responsibility (CSR) issues in developing markets have acquired a lot of attention. Organisations around the globe apply a diversified set of technologies to approaching customer expectations through banking performance. This study examines the impact of CSR on Lebanese banking performance. Primary data from questionnaires were used. A total of 1000 observations were collected using a 5-point Likert scale method adopted to formulate the items. The questionnaire was tested to assess its trustworthiness regarding data collection. Partial least square structural equation modelling (PLS-SEM) was used to test the hypothesis. The overall results demonstrated the significance of CSR in terms of meeting customers’ expectations and maintaining banking performance. All CSR dimensions demonstrated a positive impact on customer expectations and Lebanese banking performance. Moreover, customer expectations proved to be a mediator between CSR and banking performance, although there was partial mediation between CSR and banking performance.
