Sustainable Urban & Participatory Planning Summer School
Skyros, GREECE
June 30 – July 3, 2026
About
Urban deliveries, and particularly the last‑mile segment of freight distribution, are becoming one of the most critical challenges faced by contemporary cities. The rapid growth of e‑commerce, increasing consumer demand for fast and flexible deliveries, and rising levels of urbanization have significantly intensified freight activity within urban areas. Last‑mile deliveries are widely recognized as the most complex, costly, and environmentally impactful stage of the logistics chain, contributing disproportionately to urban congestion, greenhouse gas emissions, air pollution, noise, and competition for limited public space.
In response to these challenges, cities are increasingly experimenting with sustainable and innovative urban delivery solutions, such as cargo bikes, urban consolidation schemes, autonomous vehicles, and the use of public transport systems for freight. However, the successful implementation of such measures depends not only on their technical and operational performance, but also on context‑specific conditions and stakeholder engagement. Participatory planning approaches, combined with structured evaluation tools, are therefore essential to support transparent, inclusive, and evidence‑based decision‑making in urban logistics.
This Summer School offers an intensive, practice‑oriented workshop focusing on urban deliveries at the local scale. Participants will be introduced to key concepts of urban logistics and participatory planning and apply them in a real‑life urban context. A central component of the Summer School is the use of the Evalog platform, an interactive decision‑support tool for the sustainability evaluation of urban logistics measures. Based on lectures, case studies, participatory activities, and hands‑on exercises, participants will explore how alternative urban delivery solutions can be assessed, compared, and selected, through stakeholder‑driven processes and familiarize on lessons learnt, and policy implications.
Prior to the Summer School, instructors will provide participants with background material to establishe a common knowledge base on the solutions to be examined and prepare a pre-school assignment.
During the Summer School, participants will implement participatory activities and role playing, assessment and decision-making to compare and select the preferred solutions.
The Summer School is addressed to graduate students, researchers, and professionals, who will expand their knowledge and practical skills in sustainable urban logistics, participatory planning, and policy‑oriented evaluation.
Content
Unit I: Urban Logistics and Sustainable Urban Delivery Solutions
Module 1: City Logistics Challenges and Urban Delivery Solutions
Description: The module addresses key challenges associated with deliveries in cities, including congestion, emissions, land‑use conflicts, and economic efficiency, as well as the role of logistics solutions within sustainable urban mobility planning.
Module 2: Assessing Sustainable Urban Delivery Solutions
Description: The module presents operational concepts, enabling conditions and limitations, forming the basis for assessment and comparative evaluation. Implementation of the EVALOG methodology.
Unit II: Participatory Planning for Urban Delivery Solutions
Module 1: Principles and Methods of Participatory Planning
Description: This module introduces participatory planning concepts and methodologies, including stakeholder identification, engagement strategies, and collaborative decision-making processes.
Module 2: Participatory Evaluation and Decision-Making
Description: This module focuses on the application of participatory planning to the evaluation of urban delivery solutions. Participants engage in focus groups representing different stakeholder perspectives to define evaluation criteria and assign weights. The outcomes of participatory processes are then translated into structured decision-making and evaluation activities.
