Abstract
The rapid deterioration of the environment has attracted the world’s attention to find the determinants of carbon dioxide (CO2) emissions. In this line, many studies have probed the factors affecting CO2 emissions but the role of natural resources has been overlooked significantly. Therefore, this study attempts to fill this gap by investigating the role of natural resources in CO2 emissions in four South Asian countries over the annual period of 1990-2019. Other variables of trade openness, renewable energy, energy use and gross domestic product (GDP) were also included in the model. Findings of the autoregressive-distributed lag (ARDL) method reveal that natural resources reduce CO2 emissions in Pakistan and India. The abundance of natural resources, increases CO2 emissions in Bangladesh. This association was not found significant in Sri Lanka. Moreover, this research confirmed Environmental Kuznets curve (EKC) in Pakistan, India, Bangladesh and Sri Lanka. Renewable energy is reducing CO2 emissions in these countries. Therefore, natural resources are essential to reduce CO2 emissions in Pakistan and India. Bangladesh needs to utilize its natural resources efficiently to improve air quality.
