Abstract: Air pollution is one of the most dangerous and emergent problems in the modern world. Around 98% of the world’s population breathes air that exceeds WHO safety limits. In India northern states like Punjab, Haryana, Uttar Pradesh experiences surge in pollution levels due to factors like stubble burning, vehicular emissions, industrial activities and unfavourable winter metrology. The contaminants like (P. M)2. 5, (P. M)10, has worst effects on health, environment and economy. Though Bengaluru and Delhi are similar to each other in terms of Industrialization and Urbanisation but still Bengaluru has better AQI than Delhi due to governance and environmental policy. Cities like Bengaluru and Zurich on contrast with Delhi and Kuala Lumpur maintain better air quality through technological innovation and long-term planning. Beijing’s story from world’s most polluted city to modal of air quality index recovery demonstrates impact of sustained policy and citizen participation. To address the problem of air pollution, this paper developed the solution “Pollusense” a mobile based application that integrates with real time AQI that rewards user for activities like carpooling, planting, walking, cycling etc. The app has automated gamification features (streaks, leaderboard,badges) and a reward – voucher system to encourage behavioural change. The app has activity verification system which initially verify activities like, cycling and walking with GPS location, photos and distance measure. And rewards voucher after approval. Pollusense aims to reduce pollution, increase community engagement and health fitness by integrating daily personal activities with positive environmental results. The proposed solution proves how computer science, AI, IOT sensors and cloud technologies can overall contribute to improving air quality index.
