Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The country opened its largest coal-fired power plant in 2012 and has yet to implement emission controls like China.
