How hyperlocal air pollution monitoring will create smarter, healthier cities

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

Trend spotted: Home Depot is the latest retailer to drop these harmful chemicals

Last week The Home Depot published an update to their Chemical Strategy that expands their commitments to now cover household cleaning chemical products. They are asking suppliers to remove and exclude nine chemicals from these products by 2022. This commitment builds on their strategy first published in October 2017, which targeted chemicals of concern in flooring, carpet, insulation, and paints. Adding cleaning products to that portfolio builds on The Home Depot’s commitment to tackle products that impact the quality of indoor air. This commitment is important considering we spend 80% of our time indoors and many of the chemicals we are exposed to inside are linked to the development of asthma, among other health issues.

The Home Depot’s updated strategy is a move in the right direction for cleaning products. While they previously highlighted environmentally preferred products through the Eco Options® certification program, this commitment will impact all cleaning products sold in stores and online. This means more consumers will be able to bring safer products into their homes.
