Air quality researchers in Antwerp, Belgium have an unlikely new assistant: 'baby' Claire, a lifelike doll whose name is taken from her optimistic objective, "Clean Air for Everyone".
With Claire safely secured in her pushchair, voluntary babysitters roam the city's streets as three electronic sensors wedged in beside the doll record the particulate matter spewed out from factories and car exhausts.
Poor air quality has been dubbed a silent killer and deemed responsible for 7 million premature deaths worldwide each year and Belgium's notoriously clogged roads make it one of Europe's worst offenders, despite being home to just 11 million people.
Analysing the data Claire collects is Roeland Samson, a bioengineering lecturer at the University of Antwerp.
Veerle Bonaers, one of the volunteer walkers, decided to participate in the project due to her anxiety over the impact of pollution on the next generation.
Climate campaigner Joeri Thijs of Greenpeace Belgium urges the public to reconsider how they get around.
