How Do Urban Carbon Dioxide Emissions, Urban Scale and Population Density Relate to Each Other? - A Literature Based Discovery

Abstract

In this study we explore the question of whether urbanization promotes or mitigates climate change through review of prevalent empirical research that have been performed by employing various statistical and econometric models, such aspower law, urban kaya scaling and production function based models. Our study explains the strength and weaknesses of these models along with their limitations and constraints. As urban areas around the world are looking for carbon neutrality, future works based upon findings of this study would be potentially insightful in aligning the development trajectory of sustainable urbanization with economies of scale in CO2 emission of urban areas.
