Zero states that road transport is one of the main causes of air pollution, accounting for 37% of nitrogen oxide emissions, and that, currently, more than 100 European cities exceed the air quality limits established by the European Union.

"Zero calls on the government and local authorities to speed up the adoption of concrete measures and implement these types of zones, thus ensuring that everyone can breathe truly clean and healthy air", it is highlighted.

Air pollution "represents the greatest environmental risk to human health", contributing to several diseases that, in addition to the suffering caused, weigh on health systems.

In this context, Zero stresses the "urgent need" to create ZEZs, which, it says, "have already proven to be an important solution for improving urban air quality".

Data cited in the statement indicate that the number of ZEZs in operation in Europe grew from 228 in 2019 to 320 in 2022, with a forecast increase of a further 58% by 2025. According to the statement, almost three dozen cities plan to expand their existing ZEZs by 2025, with 35 cities also planning to create Zero Emission Zones by 2030.

ZEZs are zones free from the circulation of vehicles with internal combustion engines.

For Zero, it is also necessary to reinforce the implementation of reduced speed limits (the so-called 30 Zones), set at 30 kilometres per hour.
