US: As the world is becoming more conscious towards climate change and air pollution, organisers of ‘Drones & remote sensing’ conference, have decided to discuss about the same. The topic for discussion would be how to use drones for monetary factory emissions and waste. The discussion will be the part of Roma Drone Conference 2015-2016, that will be held in Rome from 20th January. Drones would complement conventional urban monitoring units and would be especially suitable for monitoring emissions from factory chimneys, industrial plants and rubbish dumps. The situation of air pollution arises across the country including cities like Milan, Rome and Naples before Christmas.
