Global Tendency of Carbon Dioxide (CO2) per GDP as a Measure of the Environmental/Economic Risk Density

Abstract

This report contains an analysis of the global carbon dioxide (CO₂) trend  among the current five great titans of the world economy (United States, China, Germany, Japan, and India); and we review how these countries are contributing to the production of greenhouse gases, where we can interpret CO₂ per GDP by country as a measure of environmental/economic risk density for the mentioned countries; from which some curvilinear relationships were measured through regression analysis, and homogeneous blocks with similar density were identified through a parametric analysis of variance (ANOVA) and a nonparametric statistical technique (Kruskal-Wallis test), where both methodologies generated the same conclusions.
