1. The photo shows a front line of high buildings, a main road, carpark, few cars, a footpath, a cycle lane, bus stop, streetlamps, a row of shrubs, few people walking. 2. The invisible information that can be extracted from this photo: •Utility services (electricity, gas, telecommunications, water, swage). Underneath the road runs a complex network of cables and pipes that are essential to our daily activities. •The CO2 emitted especially by our houses and transportation. 3. The invisible information I selected is the CO2 emitted by our cities. Air quality sensors spread across urban areas can play a fundamental role in quantifying and informing the amount of CO2 in our cities, and ultimately, in identifying the source to further address the problem. Sensors themselves don’t resolve the problem, but the information collected by them can be used by planners and urban designers to redesign the areas most affected by air pollution, which is extremely harmful to our health. Digital technology associated with environmental policies to support an economy net-zero by 2050 will together generate sustainable urban areas.
