Surrounded by nature, a deep breath can feel like a refreshing drink post exercise.
Wouldn’t it be nice if we could experience something similar on a busy road? Particularly for children, who are often perilously close to exhaust pipes.
Placing CO2 absorbing plants by the roadside is one possibility. In London and the southeast, air pollution levels can already be checked online or by app.
Meanwhile researchers at Imperial College London are investigating how different types of roadside wall can improve air quality.
Findings indicate that a curved wall would be best suited for deflecting pollution back onto the roads. The barriers would reduce noise levels on the streets, and could be adorned by CO2 absorbing plants.
Ahead of the curve!
