Hi,
This ones for the smartphone warriors among us. Just spotted this new app called CleanSpace - basically gives you data on the air quality around you and your travel routes. There's also an air tag which acts as a personal air quality sensor and will allow you to pick cleaner, less polluted travel routes when walking, running, cycling.
As a father of two living in London this seems like a much needed programme to get involved in! Check it out here
