Gujarat launched a market-based trading system to reduce air pollution, where the government sets a cap on emissions and allows industries to buy and sell permits to stay below the cap.

The Gujarat Pollution Control Board (GPCB) has lauched this initiative. The programme, first announced in January, takes advantage of GPCB’s earlier innovation of using continuous emissions monitoring systems to track industry emissions in real time. About 350 industries around Surat have installed these systems and now transmit real-time, “high-quality” emissions data.
