The article highlights the efforts of the Polish New Mobility Association (PSNM) in driving the transition towards a zero-emission transport sector in Poland and the Central and Eastern Europe (CEE) region. PSNM, as the largest organization shaping e-mobility and hydrogen technology markets in the region, focuses on various aspects of sustainability and innovation in the transportation sector. PSNM's work includes promoting electric vehicles (EVs) and expanding EV charging infrastructure, with over 75,000 battery electric vehicles (BEVs) and close to 8,000 charging points already in operation in Poland. The organization also addresses the electrification of heavy-duty vehicles, an essential sector in Poland's economy, by collaborating with global partners to develop initiatives like eHDV corridors. Moreover, PSNM's efforts extend to greening cities through strategies for bicycles, micromobility, and multimodal transport options. The organization advocates for industrial development based on zero-emission technologies and envisions the CEE region becoming a hub for battery technology, hydrogen energy storage, and other innovative solutions. The article emphasizes the rapid transition expected in the transport market, with a significant reduction in internal combustion engine (ICE) vehicles and the mainstream adoption of BEVs. PSNM aims to lead this change in Poland and the EU with support from partners and organizations like AVERE. Finally, the article invites readers to explore more insights on the e-mobility transition by downloading the organization's e-book, "Smart Roads, Green Cities. How CEE drives the e-mobility transition."
