After a long wait, the world’s first zero-emission aircraft are finally a reality. The European Union Aviation Safety Agency (EASA) has certified a two-seater aircraft made in Slovenia for flight. Within a few years, it would be certified in the UK, the US, and other regions. The Pipistrel Velis Electro became the first fully certified electric aircraft in the world and remains the only one with full certification. However, the uptake of electric aircraft is still a long way off. Despite the growing number of cleaner aircraft being developed, significant questions remain about the alternative fuels needed to power them, and the political will to implement these technologies is still uncertain.
