Sorting Greenhouse Gases Based on Human and Environmental Impacts Using (MCDA)

Abstract

AbstractGreenhouse gases are a global problem due to their dangerous impacts on the human health and environment. Climate change is the main result of greenhouse gases emissions which cause severe weather conditions, droughts, wildfires, disruption of eco-system, floods, pollution of air, disturbance of food supply system and extinction of animal species. The main sources of greenhouse gases are fossil fuels combustion in manufacturing such as cement manufacturing, agriculture activities and deforestation. Greenhouse gases consist of many gases; the most important greenhouse gases are Carbon Dioxide (Co2), Methane, Nitrous oxide, fluorinated gases including ChloroFluoroCarbon, HydroFlouroCarbon, Sulfur Hexafluoride and Nitrogen Trifluoride. The aim of this study is to sort greenhouse gases based on their impacts on human and environment, radiative forcing and atmospheric life time using Multi criteria Decision Analysis (MCDA). Fuzzy PROMETHEE method was used for sorting; it’s a combination between PROMETHEE method and Fuzzy logic to consider ambiguous conditions. The results of the analysis sort Nitrogen Trifluoride as the first gas because it has less impacts on human and environment with less radiative forcing. Sulfur Hexafluoride, HydroFlouroCarbon and ChloroFluoroCarbon were sorted on second, third and fourth position. Carbon dioxide was sorted as the last gas because it has the worst impacts on human and environment due to high radiative forcing.KeywordsGreenhouse gasesFluorinated gasesMulti criteria decision analysisPROMETHEE methodFuzzy logic
