The document discusses sustainable urban logistics and delivery solutions. It notes that by 2050, 70% of the world's population will live in cities, putting pressure on mobility and the environment. Currently, last mile delivery costs make up 13-75% of total logistics costs. The document then introduces Bubble Post, a logistics company that aims to address these issues through consolidated and optimized deliveries using small, fast electric vehicles. Bubble Post receives goods at city outskirts, sorts them, and uses time window deliveries and mobile notifications to improve the first delivery attempt rate. Their approach seeks to make deliveries more sustainable and customer-centric.
