Emissions of the existing gasoline engines and brakes of the commercial vehicle fleets in Europe relate to health problems and death of annually >1,45 Mio. people. For the next decades, these vehicles will continue populating the roads, emitting PM/PN exhaust particles and toxic secondary emissions. For immediate reduction, retrofit solutions for tailpipe and brake emissions must be brought to TRL 8 and introduced to the market by 2025. Timing is crucial: Retrofits are transition technologies until full electrification of Europe’s transport fleet. Even beyond, brake retrofits play an important role in the electrified fleet. Quick wins in the reduction of the overall footprint of the existing fleets can be realised by using our 3 retrofits for tailpipe, brake and closed environments: 95% of PM2.5 and 80% of toxic secondary emissions using an innovative Gasoline Particle Filter, 60% of NOx exhaust emissions replacing the aged TWC by original equipment, 90% of the brake particles of long-lived road transport assets using a passive BDPF, 90% of particles in closed environments (bus stops, tunnels, metro stations) using a special designed and enhanced stationary air purifier. To create credible key messages for clients, citizens and policy, we perform lighthouse demo activities: 1) tailpipe retrofit: 1.000 vehicles in 2 climate zones (Germany + Israel) for 4 representative engine type families, 2) brake retrofit: Define emission fingerprints for the public transport of the cities of Valladolid, Ancona, Fermo and Sofia and > 35000 km lab testing on dynamometer and > 8000 km real driving, 3) air purifier retrofit for closed environments: 3 underground stations (Sofia, 2x Lisbon) with > 130000 commuters and Valladolid central bus depot with > 150 buses. For market preparation we will reach >4.000 citizens and policy makers from EU KOM level and >8 EU countries. We unite world leading industry, renowned scientific institutes and lighthouse demo sites in 8 European countries

SPINE’s vision is to accelerate the progress towards climate neutrality by reinforcing PT systems through their smart integration with new mobility services, sharing schemes, active transport modes, and micromomibilty. SPINE adopts an equity centred design thinking approach, leading the transition to a more efficient, sustainable, resilient, and inclusive PT system. A network of collaborative LLs is developed to foster transferability, while an intersectional view of the transport system users is applied. Four Lead City LLs in Antwerp, Bologna, Tallin and Las Palmas will be established, and a series of co-creation activities will take place where multiple stakeholders will be actively engaged in the development and demonstration of efficient, replicable, and socially acceptable innovative mobility solutions, advancing existing assets. The SPINE approach involves the creation of (a) innovative simulation and Digital Twining (DT) tools, along with open data and behavioural models, that will allow the building of scenarios combining different mobility interventions (push and pull measures along with supporting policies) and the implementation of the most promising ones; (b) data-driven impact assessment models that will foster the twinning, transferability and adaptation of the successful solutions of the four LLs in seven Twining Cities - Barreiro, Valladolid, Zilina, Sibenik, Hrakleion, Gdynia and Rouen-. SPIRE sets a high ambitious plan for the co-design and implementation of 55 smart greens inclusive mobility solutions. The SPINE consortium brings together a multidisciplinary team of 39 partners from 16 countries. The unique mix of experienced transport engineers, Public transport Operators, computer scientists, data analysts, transport modelers, social scientists, urban planners, policy analysts, software providers, within our consortium assures the comprehensive approach to the challenges, scope, expected impact and the successful delivery of the project.
