Gujarat chief minister Vijay Rupani launched India’s first emissions trading scheme (ETS) on June 5, pressing ahead with the government’s efforts to curb air pollution by reducing particulate matter (PM) emissions. June 5 is marked as World Environment Day and air pollution was the theme of this year’s event. The team that has formulated the ETS includes researchers from the Economic Growth Center at Yale University, the Energy Policy Institute at the University of Chicago (EPIC), and The Abdul Latif Jameel Poverty Action Lab (J-PAL).
