Abstract
Human-driven Greenhouse gases (GHGs) are the most significant contributor to climate change. World countries and Egypt are moving towards achieving sustainable development goals (SDGs) 2030, and 2050, to reach Net-Zero emissions. This research assesses and monitors the GHGs emissions induced by human activities in Egypt based-on satellite ob-servations. Multiple-satellite sensors (e.g. MODIS and AIRS) were utilized in this study to obtain Methane (CH4), Carbon Dioxide (CO2), air temperature, and Normalized difference vegetation index (NDVI) data during 2015-2022. To get a deeper insight into the effects of anthropogenic activities on GHGs, temperature, and NDVI were correlated with the GHGs to investigate their effect on the emissions. Results revealed a noticeable increase in CH4 and CO2 emissions over the country, particularly in the Nile delta, since 2015, with a maxi-mum value in 2022. CO2 concentration was higher in summer, which is characterized by high anthropogenic activities and temperature than in winter, reaching a peak of 0.00042 CO2/mol dry-air in 2022. While, high CH4 concentration fluctuates all the year-round, with a peak of 1962.28 ppbv in 2021. The correlation between GHGs and temperature was posi-tive while with green cover it was negative (R2=0.7). In conclusion, unmanaged human activities in Egypt increased GHGs release and affected environmental sustainability. This study attempts to better understand the ambient environment in Egypt and support the deci-sion-makers with full insight into the GHGs emission hotspots in the country to mitigate their release into the atmosphere and achieve Net-Zero emissions.
