Amid dynamic shifts in both domestic and international economic landscapes, climate changeClimate change emerges as a pressing issue demanding collective action. The energyEnergy sector stands out as a primary source of greenhouse gas (GHG) emissions, especially Carbon dioxide (CO2), necessitating substantial investments to uphold climate protection and advance sustainable developmentSustainable development. In recent years, there has been surge in interest and discourse surrounding global warming and sustainable developmentSustainable development. The issue of climate changeClimate change has captivated an ever-growing community of researchers and policymakers, prompting a deep dive into the factors responsible for global warming and climate shifts. With this background, the study attempted to assess the association between CO2 with the growth of the economy and energyEnergy consumption in three major emitters of the world. The study investigated the relationship among EnergyEnergy consumption, Economic GrowthEconomic growth (GDP), and Carbon dioxide (CO2) in nations like China, Japan, and India over the period of 1990 to 2020. The study purposively selected China, Japan, and India which are the three major emitters in the world. The results show a significant correlation among these variables revealing high dependency on each other. China and Japan emerge as the top emitters than India. China’s policy efforts fall short of achieving zero emission targets whereas Japan’s efforts comprise assisting developing nations in achieving carbon neutrality goals. India is actively striving toward achieving carbon neutrality before 2070, albeit facing challenges in implementation. The efforts of China and Japan are in the right direction as both possess a plethora of resources, whereas the effort of India is commendable even with fewer resources. These three countries possess the power to steer the climate politics in the right direction.
