For the first time in four years India’s sulfur dioxide (SO2) emissions recorded a significant decline of approximately 6% in 2019 compared to 2018, the steepest dip in four years, reveals an annual analysis from Greenpeace India and the Centre for Research on Energy and Clean Air (CREA). However, India continues to occupy the top emitter’s position for the fifth consecutive year. The report ranks the world’s biggest emitters of sulfur dioxide, a poisonous air pollutant that increases the risk of stroke, heart disease, lung cancer, and premature death.
