Abstract

This study analyzes air pollution concentration and its determinants in ten countries with the highest levels of air pollution from 2010 to 2020. Air pollution has become a global issue affecting both human health and the environment. The study uses secondary data and applies two analytical tools: a concentration index to identify countries with the highest air pollution levels, and panel data regression to analyze its determinants. Air pollution is proxied by CO2 emissions. The results indicate that eight out of ten countries have a concentration index greater than one, with Japan, South Korea, and Germany ranking as the top three countries with the highest air pollution concentrations. The population variable has a positive and significant impact on air pollution concentration in these countries. Conversely, the energy consumption variable has a negative and significant effect on air pollution concentration. On the other hand, economic growth does not have a significant effect on air pollution concentration. The study's implications highlight the need for a transition to more efficient and renewable energy sources as a crucial step in reducing the negative impacts of air pollution. Stricter environmental policies and increased investments in eco-friendly technologies are highly recommended to address this issue

Abstract

This study analyzes the concentration of carbon dioxide (CO2) emissions and their determinants in 25 Asian countries from 2015 to 2021. Carbon dioxide (CO2) is a greenhouse gas produced by human activities, such as fossil fuel combustion. The study utilizes secondary data and employs two analytical tools: the concentration index, which identifies countries with the highest CO2 emissions, and panel data regression to analyze its determinants. The findings reveal that 13 out of 25 countries have a concentration index greater than one, with Japan, Russia, and Azerbaijan ranking as the top three countries with the highest CO2 emission concentrations, while Vietnam has the lowest concentration index, with a value of less than one. The variables of oil consumption, natural gas consumption, coal consumption, and population size have a positive and significant effect on CO2 emissions in the 25 Asian countries. On the other hand, economic growth does not have a significant impact on CO2 emissions. These findings highlight the urgency of implementing energy transition policies in high-emission countries as a strategic measure to reduce dependence on fossil fuels. Furthermore, the development of population-based policies oriented toward sustainability is deemed crucial to effectively reducing carbon emissions across the Asian region.
