It’s true that in many cities, air quality is better now than it was decades ago. But urban air quality is still a health risk in far too many places. Premature death from air pollution is about 50 percent more common in cities than in rural areas. On days with higher air pollution, stock returns are lower, and students perform worse on exams. Companies in highly polluted cities have to offer a form of “hazard pay.” And with about 1.5 million people relocating to urban centers every week, air quality will remain a persistent and urgent problem for city leaders around the world.
What do Houston, London, and San Francisco have in common? You might be thinking about great food, an excellent job market or a thriving arts scene, but the answer is that all three cities are taking action to improve their understanding of an often invisible urban threat: air pollution.
When you picture a city bus, an animal control van or a waste management truck, you’re probably not thinking about a high-tech, mobile urban sensing platform, about saving millions of lives, or about the smart city of the future. At least not yet. But a new initiative in Houston is turning public fleets into the rolling eyes and ears of the city, and enabling these vehicles to revolutionize the way air pollution is monitored, measured – and ultimately addressed across the United States.
The information generated by these IoT-enabled “future fleets” is also a key tool in the transformation to fully connected, smarter cities, where hyperlocal data makes streets safer and less congested and where market forces reward urban efficiency, decarbonized electricity, and clean transportation. Picture using connected, clean fleets to improve delivery times, bring residents to work, school and doctor’s appointments, and even pinpoint the location of toxic air pollution threats – all at the same time.
These vehicles are enabling a future where air pollution forecasts eliminate hundreds of thousands of heart attacks, tens of thousands of hospital and ER visits, and an even larger number of missed school and workdays that are caused annually by air pollution. Air pollution also costs the global economy $225 billion dollars every year in lost labor income, but recent studies show that improving air quality – both indoors and outside – could improve worker productivity.

Right outside my window in Washington, DC, there is a hill where trucks accelerate towards the north, and buses idle to pick up tour groups. Even when the air looks clear, it may be hiding an invisible danger. Air pollution kills 4.5 million people a year and costs the world $225 billion a year in economic damages. These global figures mask what can be a highly local, personal risk. Recent studies show that air pollution varies as much as eight times within one city block. We also now know that living by streets with the most elevated pollution can raise the risk of heart attack or death among the elderly by more than 40% – suggesting air pollution is far more dangerous than previously understood.
The good news is we are on the cusp of generating widespread hyperlocal insights into air pollution. Understanding for the first time at a local, personal level where pollution is, where it comes from, and its impacts could shine a spotlight on the problem and increase the urgency and motivation for action. Because the best actions will protect health and mitigate the risk of climate change, local insights can provide the springboard for local, regional, national and even global impact. Read more
