Most of India's coal-fired power plants may miss the deadline to curb toxic emission, according to a report by the Centre for Science and Environment. This may hinder efforts to curb air pollution, the report said. The 2022 deadline for restricting sulfur dioxide emissions maybe missed by 70% of the capacity and the Covid-19 pandemic may accelerate these worries. According to CSE, these plants are the biggest source of pollution emissions, contributing 60% of the total particulate matter emissions. The emission norms were set in December 2015 by the Ministry of Environment, Forest and Climate Change. The report gives certain recommendations, including hefty fines that must be imposed by the environment ministry.
