Non-fossil fuels are receiving increasing attention within the context of addressing global climate challenges. Based on a review of non-fossil fuel consumption in major countries worldwide from 1985 to 2015, the purpose of this paper is to analyze trends for global non-fossil fuel consumption, share of fuel consumption and inequality.

The similarities were obtained between the logarithmic mean divisia index and the mean-rate-of-change index decomposition analysis methods, and a method was proposed for complete decomposition of the incremental Gini coefficient.

Empirical analysis showed that: global non-fossil fuel consumption accounts for a small share of the total energy consumption, but presents an increasing trend; the level of global non-fossil fuel consumption inequality is high but has gradually declined, which is mainly attributed to the concentration effect; inequality in global non-fossil fuel consumption is mainly due to the difference between nuclear power and hydropower consumption, but the contributions of nuclear power and hydropower to per capita non-fossil fuel consumption are declining; and population has the greatest influence on global non-fossil fuel consumption during the sampling period.

The main contribution of this study is its analysis of global non-fossil fuel consumption trends, disparities and driving factors. In addition, a general formula for complete index decomposition is proposed and the incremental Gini coefficient is wholly decomposed.

Informal street vending is traditionally widespread and studied concerning developing countries. Nevertheless, recently, interest in the study of this practice has also increased regarding specific developed countries. The aim of the article is to contribute to overcoming the tendency to investigate this informal economy sector with different analytical lenses between the global South and global North and to highlight the usefulness of analyzing the phenomenon from a comparative perspective.

Therefore, the article represents a comparative review of the existing literature on informal street vending considering both the global South and global North.

The analysis revealed similarities and differences in the characteristics the phenomenon assumes in the two areas of the world while at the same time, showing how there are aspects mainly explored in the literature of southern countries and little explored in the literature of northern countries and vice-versa.

This analytical attempt allows us to highlight any gaps present in the literature, which may represent the basis for future comparative research on the topic. Comparative research will improve both theoretical and empirical knowledge of the phenomenon.

On the one hand, the article represents an innovative literature review attempt, as it explicitly compares the street vending between developing and developed countries. On the other hand, it represents the first academic contribution to review street vending in the global North.
