New Initiatives

-- Delhi is now considering deploying a more cost efficient multiple sensors to enhance the coverage further^[3]
-- Delhi govt to deploy AQM Vans at schools to provide real-time information about air quality and enable teachers to make informed decisions regarding outdoor activities^[4]
