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
