Lviv ran six annual participatory-budget cycles from 2016; turnout grew from 21,215 to 145,573 voters (99%+ online) and the 2021 cycle funded 101 projects worth UAH 77.8m. New cycles are suspended since Russia's 2022 invasion, most 2021 winners still unfinished.
Lviv introduced participatory budgeting (PB) in June 2016, one of at least 154 Ukrainian communities to adopt it between 2015 and 2019. Residents submit costed projects and vote for two weeks each November on a municipal e-platform.
Turnout rose from 21,215 voters in 2016 to 145,573 in the final 2021 cycle, with over 99% of 2021 votes cast online; the 2021 cycle drew 254 proposals requesting UAH 259m and funded 101 winning projects worth UAH 77.8m. An independent 2019 evaluation ranked Lviv the highest-turnout city of its population class (9.9% of residents voting in 2017), though the same evaluation found no statistically significant relationship nationally between turnout and PB funding share or completion rate.
The programme was suspended when Russia's full-scale invasion began; Lviv's executive committee cancelled the 2022 call under martial law and no new cycle has run since. Transparency International Ukraine's November 2024 review found Lviv had stopped financing PB projects altogether, with just 18 of the 101 projects funded in the final 2021 vote completed and 83 still 'in implementation' as of mid-2026.
