The article compares environmental quality and economic growth in China and India to see if there is a pattern called the environmental Kuznets curve. This curve shows how economic growth affects the environment. The researchers looked at data on carbon dioxide emissions, GDP, and energy use from 1972 to 2017. They found that both China and India follow the curve, but China's environment will get worse at a slower rate than India's because of high energy use. When GDP increases, India's environment improves faster than China's. This study helps us understand how economic growth and energy use impact the environment in these two countries.
