India's sulphur dioxide emission grew 50% in a decade: Study
A NASA-funded study has found that India would soon overtake China as the world's top sulphur dioxide (SO2) emitter after its emissions rose by 50% since 2007, while the latter's declined by 75% for the same period. SO2, mainly produced by coal-burning power plants, is an air pollutant that causes acid rain, haze, and many health-related problems.
