Abstract: Carbon dioxide emissions is one of the main climate change causes. Nowadays is considered as one of the most important environmental degradation and air pollution in the world. The relationship between CO2 emissions and their socio-economic determinants is investigated in this study. It uses empirical analysis of significant impact of the economic growth, the tourism development, the globalization, the population health, the population growth and the energy consumption on our interest variable. Thus, we're going to select an econometric model, an Autoregressive Distributed Lag model (ARDL) applied to a sample of 10 MENA countries. Our aim is to measure, long-run and short-run impact of the number of arrivals, the Foreign Direct Investment, government health expenditures, the energy consumption and the population growth rate on the CO2 emissions. All variables are observed from 1995 to 2020. The methodology adopted in this work is as followed: First, the statistical indicators for the sample are calculated. Secondly, the temporal series stationarity is checked by realizing tests of first and second generation. The Pedroni ARDL and Pesaran cointegration tests are then applied. Finally, Granger causality for panel data is used. The causality analysis between variables is carried out using the Dumitrescu and Hurlin's test. Findings reveal that, in the long term, tourism sector and energy consumption have significant and positive impact on CO2. But the economic growth and population growth influenced it negatively and they are statistically significant. In the short term, the dependent variable is statistically impacted by economic growth. The degrees and magnitude of the individual effects of the various variables on the Carbone dioxide emissions vary from country to an other. There are bidirectional and unidirectional relationships causality between different variables. Our findings can be helpful for policy makers seeking to achieve the sustainable development goals in MENA region.

Abstract: Highly developed nations worldwide encounter a notable energy demand as their main obstacle. Furthermore, the building sector plays a significant role in contributing to carbon emissions and climate change. In the UAE, buildings consume the largest portion of energy due to the improper selection of design parameters during the building's design phase, which are specifically tailored for the remarkably hot climate in the country. As a result, various studies, initiatives, and policies are focused on enhancing the energy efficiency of buildings. Additionally, retrofitting existing buildings has emerged as a crucial approach to achieving energy efficiency, resulting in several benefits such as reduced costs for operation and maintenance. This research performed an analysis of a commercial building in Abu Dhabi using DesignBuilder, based on energy modeling and simulation. Five main retrofits were examined, accompanied by a cost analysis to determine the most appropriate retrofit for future investments. The results demonstrate that increasing the cooling set point temperature by 4 degrees led to a 19.53% decrease in the annual cooling load. Additionally, retrofitting the chiller resulted in a 16.11% reduction in the annual cooling load, whereas wall insulation had the least impact as a retrofit. It was observed that improving the chiller's coefficient of performance (COP) offered significant advantages, with a payback period of around 5 years, making it the most favorable retrofit for investment. However, the glazing and wall insulation retrofits were considered less beneficial due to their high initial costs and long payback periods.
