Last mile delivery represents the final stage of the logistics chain, in which the products are delivered to the end user. This stage is crucial in the supply chain because it significantly affects the customer experience, as well as the overall cost of delivery. Given the continuous growth of online commerce, urban delivery is becoming more and more complex, and processes need to be optimized to reduce costs and increase efficiency. This paper analyzes how various factors, including technology and infrastructure, affect the delivery process and costs. Special emphasis was placed on innovative solutions such as autonomous vehicles, drones and electric vehicles, and on their potential to reduce negative environmental impacts. Also, it is being investigated how urban logistics can become more sustainable through the optimization of routes, the use of environmentally friendly vehicles and the reduction of CO2 emissions. Through an analysis of current practices and future trends, this paper seeks to provide a comprehensive overview of the key challenges and opportunities in last mile delivery.
