periASTY envisions fostering the integration of peri-urban areas’ transition towards climate neutrality by advancing and developing mobility, energy, industry, and governance-related net zero technologies and business models. A suite of innovations, the periInnovations, is designed to host technological and non-technological solutions. The periInnovations suite offers four groups of innovations: 1. periMOBILITY aims to reduce car dependency in peri-urban areas (active modes, multimodality, mobility services); 2. periENERGY concentrates efforts on reducing emissions and promoting sustainable energy sources (energy system demand, energy charging hubs, renewable local energy communities); 3. periINDUSTRY focuses on reducing GHG emissions, improving efficiency in industrial operations, and promoting a circular economy and reuse (urban mining, circular economy, local green deals, waste management); 4. periGOVERNANCE supports governance, planning, and decision-making (governance framework for functional urban areas (FUA) digital twins, AI-based data warehouse) and builds capacity among local authorities and stakeholders on implementing climate-neutral concepts, integrated planning, and attracting investments/funding (periSKILLS Academy). The periInnovations are integrated into real-life mobility, energy, and industry services, operations, and infrastructure, allowing the demonstration of the co-designed concepts in nine diverse Living Labs across peri-urban areas: Dublin, Limassol, Ljubljana, Marseille, Guimarães, Helmond, Kalamata, Sofia, and Sisslerfeld (Switzerland). periASTY is more than just a consortium; it is a transformative, Europe-wide initiative dedicated to accelerating the transition of peri-urban areas towards climate neutrality. By integrating sustainable mobility, energy, and industrial solutions, periASTY directly supports the objectives of the Green Deal, Mission Climate-Neutral, Smart Cities, and other EU partnerships for 2030.
