1. According to the https://en.wikipedia.org/wiki/Climate_Change_and_Energy_Transition_Act, all Spanish municipalities with more than 50 thousand inhabitants must create a Low Emission Zone (https://en.wikipedia.org/wiki/Low-emission_zone) before the end of 2023. A Low Emission Zone basically limits which internal combusion engine cars can enter it and what they can do inside (e.g., not allowed to park on the street, transity only, etc...).

2. The next municipal elections in Spain take place on May 28th 2023 (https://en.wikipedia.org/wiki/2023_Spanish_local_elections).

3. Valencia (city) is governed by a progressive coalition (https://en.wikipedia.org/wiki/Coalició_Comprom%C3%ADs) that has, among other things, put a strong emphasis on reducing car traffic in the city.

So, the question is whether the ruling coalition will introduce the Low Emission Zone before the municipal elections (and possibly risk the drivers' backlash), or will they rather delay it (and possibly risk angering their base).

Resolves to yes if: a Low Emission Zone in Valencia is announced before May 28th 2023 (its conditions and its start date) and is published in an official gazette (e.g. BOE https://en.wikipedia.org/wiki/Bolet%C3%ADn_Oficial_del_Estado or DOGV https://es.wikipedia.org/wiki/Diario_oficial_de_la_Generalidad_Valenciana). It will also probably be widely reported in the media, so resolving this question should be straightforward.

Note: the Low Emission Zone only needs to be announced before May 28th, the actual start date may or may not be by May 28th.
