As urbanization, industrialization, and consumption grow, environmental pressures multiply. Applications such as building-automation systems, dynamic electricity pricing, and some mobility applications could combine to cut emissions by 10 to 15 percent. Air-quality sensors do not automatically address the causes of pollution, but they can identify the sources and provide the basis for further action. Sharing real-time air-quality information with the public via smartphone apps enables individuals to take protective measures. This can reduce negative health effects by 3 to 15 percent, depending on current pollution levels.

Water-consumption tracking, which pairs advanced metering with digital feedback messages, can nudge people toward conservation and reduce consumption by 15 percent in cities where residential water usage is high. In many parts of the developing world, the biggest source of water waste is leakage from pipes. Deploying sensors and analytics can cut those losses by up to 25%. Applications such as pay-as-you-throw digital tracking can reduce the volume of solid waste per capita by 10 to 20 percent. Overall, cities can save 25 to 80 liters of water per person each day and reduce unrecycled solid waste by 30 to 130 kilograms per person annually.
