Internet shopping continues to rise worldwide. That means a lot more delivery vans on the streets of our towns and cities. Those vans and trucks, often powered by dirty diesel engines, are contributing to air pollution problems that can cause significant increases in premature death and great discomfort for people suffering from heart and lung conditions. Tom Heap sets out to see whether drones or robots could be the answer. First broadcast on Costing the Earth, 8 March 2017.
