Extended progress report on the Valencia CityLab during 2023

This publication results from the collaboration between the Valencia City Council, Universitat Politècnica de València, and the Joint Research Centre (JRC) of the European Commission. Focused on urban sustainability, this joint effort aims to enhance the understanding and management of urban emissions and mobility through comprehensive data analysis and innovative methodologies. Six key studies are summarized, each addressing different aspects of urban sustainability in Valencia: — Vehicle Emissions Trends: This study analyses vehicle emissions using electromagnetic loops and an origin-destination matrix, assessing the impact of pandemic-related measures and providing policy recommendations for reducing transportation-related pollution. — Mobility Emissions Methodology: Utilizing open-source geo-statistics, this research develops a methodology to measure emissions at the neighbourhood level, offering insights into which areas could benefit from shifts to active transportation or improved public transit. — Metropolitan Emissions Analysis: By analysing emissions in Valencia's metropolitan area, this study high-lights significant discrepancies between municipalities, emphasizing the need for targeted emission reduction measures in highly polluted areas. — Sustainable Mobility and Emission Reduction: This project explores strategies for promoting sustainable urban mobility, such as enhancing public transportation and encouraging active transportation modes, with the aim of reducing CO2, NOx, and PM emissions. — Air Quality and Environmental Justice: Focusing on NO2 concentrations measured by passive dosimetry, this study identifies vulnerable areas with poor air quality and provides recommendations for addressing urban environmental inequities. — 15-Minute City Accessibility: Analysing service accessibility within a 15-minute framework, this research highlights the need for equitable urban planning to improve access to services for both residents and tourists. The findings underscore the critical role of data-driven approaches and spatial analysis in addressing urban sustainability challenges. The methodologies developed provide valuable tools for policymakers to allocate resources effectively and implement evidence-based strategies for emission reduction and sustainable development. This collaborative work highlights the importance of integrating scientific research with urban planning to create healthier, more liveable cities.
