- The Sustainable Development Goal 7 endeavors to ameliorate the energy system towards sustainability. Monitoring the country's progress to the goal will be of utmost for the government to take suitable actions and thus, constructing a performance monitoring index for Sustainable Development Goal 7 would tune the pace of implementation. This study aims to develop a novel Sustainable Development Goal 7 or Energy Sustainability Composite Index to assess the energy sustainability performance. Since Europe tends to have diverged efforts towards energy sustainability, assessing them with the proposed Sustainable Development Goal 7 composite index would provide the evidence needed for effective sustainable development strategies. By describing Europe, the authors signify 40 European countries and the selection of country depends on the availability of all the data that are required for the energy sustainability assessment. In this study, the analyzed energy sustainability aspects include clean energy conversion, energy security, energy accessibility, energy intensity and carbon intensity. The results show that Iceland, Norway, and Sweden tops in energy sustainability aspects with scores of 0.7313, 0.6967, and 0.6313 (on a scale of 0 to 1), respectively. The proposed Sustainable Development Goal 7 composite index is also compared with the actual Sustainable Development Goal 7 index, which comprises the indicators defined by the United Nations. The prime difference between the proposed Sustainable Development Goal 7 composite index and the actual Sustainable Development Goal 7 index resides in the consideration of energy security and carbon intensity indicators and in the framework designed to evaluate the clean energy prevalence. The evaluated actual Sustainable Development Goal 7 index scores of Germany and France are 0.4915 and 0.4656, respectively. On comparing with the proposed Sustainable Development Goal 7 composite index scores, the scores decreased by 20.9% for Germany and increased by 7.2% for France. The robustness of the proposed composite index relies on reducing the effect of outliers by using a modified min–max methodology, namely Aggregated Normalization based on Maximum and Minimum Outliers for normalization and the subsequent weightage allocation criteria utilized in Analytic Hierarchy Process methodology. Sensitivity analyses highlighted that the clean energy indicator is the most influencing indicator for the designed composite index. Nevertheless, uncertainty analysis indicates that the weightage scenario has a more prominent influence than various normalization and aggregation methods.

- Europe anchored aspiring targets in achieving climate neutrality and this motivates the research communities to analyze, investigate and frame strategies to achieve the goals in the stipulated timeframe. This study reviews the effective decarbonization strategies in the context of Europe's climate neutral vision. Initially, the study analyzes the reasons for ever-increasing emissions and investigates the perception of decarbonization in line with various influencing factors such as population size, economic growth, energy intensity, emission intensity, innovation, affordability and time. Subsequently, an in-depth qualitative analysis is performed to force out the challenges that Europe faces in decarbonizing the heating sector from the aspects, such as using clean energy resources, effective heat energy conversion and management approaches. Sustainable approaches and practices are proposed to mitigate carbonization and to promote carbon sink in line with the major problems associated with various sectors such as building, energy, industry and transportation sector. Furthermore, the roles of digitalization in decarbonization are explored and the inherent challenges are also discussed. This study also reviews various decarbonization policies that can direct the governments' action to effectively make a transition towards a climate-neutral society. The key findings highlight that solar energy utilization in small-scale is relatively not preferable for heat energy conversion in Europe due to climatic conditions, while district heating network with bio- and geothermal energy resource highly favors clean heat transformation scenario. In addition, 3D printing has a prodigious role to reduce building lifecycle emissions and hybrid policies as well as reward-based policies yields better outcomes. Promoting hydrogen utilization and carbon capture storage and utilization technologies can pivot climate neutrality in the sectors that are difficult to decarbonize. On the other hand, it can be observed that more focus is provided to reduce emissions and significantly less attention is focused on carbon sink.

- Background: The novel coronavirus disease-2019 (COVID-19) has seriously affected the lives of millions of people across the world. It has also heavily burdened healthcare professionals and the virus poses serious risks for their personal and professional lives. Therefore, the present study examined the associations between fear of COVID-19 and workplace phobia among doctors in Pakistan during the COVID-19 pandemic. Methods: An online survey was conducted among 421 doctors in Pakistan between April 10 and May 25, 2020. The Workplace Phobia Scale (WPS) and the Fear of COVID-19 Scale (FCV-19S) were the main psychometric instruments used in this study. Results: There was a significant positive relationship between fear of COVID-19 and workplace panic anxiety and workplace avoidance behavior. Significantly higher fear of COVID-19 was found among (i) females compared to males, (ii) doctors with 5 years or less of work experience compared to those with more than 5 years, and (iii) postgraduate trainees compared with other ranks. Two groups (doctors who were above 30 years old and postgraduate trainees) were found to have higher levels of workplace phobia compared to their counterparts. Doctors with severe levels of fear of COVID-19 had significantly higher levels of workplace panic anxiety and workplace avoidance behavior. Conclusions: Fear of COVID-19 was significantly associated with workplace phobia which may negatively affect doctors’ performance. Therefore, important steps are needed to protect doctors’ health by providing sufficient resources to allay their fears and anxieties which consequently help them in carrying out their frontline duties in response to the COVID-19 pandemic.
