Decidim Sant Cugat - Pressupostos Participatius (district-tier participatory budgeting)
Sant Cugat splits its participatory budget into six neighbourhood processes on Decidim (Centre, Les Planes, Mira-sol, La Floresta, Valldoreix, Sud-Oest). Each neighbourhood gets its own micro-budget envelope and a parallel process where residents propose, debate at Neighbourhood Councils, and vote on local projects. 2022-23 cycle: 815 proposals across 6 neighbourhoods; Centre alone got 226 proposals and 6,247 supports. Children/youth budget envelope of €140k for 2025-27.
Six neighbourhood processes are visibly grouped on the same Decidim platform with sibling pages, support counts, proposal counts and turnout visible per neighbourhood. The platform's process-groups feature is explicitly designed for inter-district visibility, creating implicit comparison ('Centre got 226 proposals, what about us?').
Each neighbourhood has its own Neighbourhood Council that meets in person to debate and validate proposals before voting. Residents must collectively rally 'supports' for proposals to advance - a single proposer cannot push a project through alone. Hybrid online/offline meetings reward in-person organising.
Concrete, currently-running Decidim deployment that goes beyond a single city-wide vote and actually structures the budget around neighbourhood-tier competition. Under-cited in English-language civic-tech writing; specific to Catalan municipal practice.

CitizenLab / Go Vocal Representativeness Dashboard
Belgian civic-engagement SaaS used by cities across Europe to run consultations, ideation, participatory budgeting. The Representativeness Dashboard compares each participating cohort's demographics (age, gender, neighbourhood, education) against the underlying ward/postcode-level population so cities can see which neighbourhoods are over- or under-represented in real time, and target outreach.
Sustrans Big Walk and Wheel (formerly Big Pedal)
UK's largest inter-school active-travel challenge run by Walk Wheel Cycle Trust (Sustrans). For two weeks, schools log every walked, wheeled, scooted or cycled journey via a school portal; a school's best five days determine final position on a national leaderboard, with badges and certificates.
Energy Sparks (UK schools energy league)
Open-data platform that ingests half-hourly electricity and gas meter readings for ~620+ schools and turns energy investigations and saving actions into points. Public national, regional (London, North-West England, etc.), Multi-Academy-Trust, and Local Authority scoreboards rank schools in real time across the academic year. Cash prizes for top schools are spent on a sustainability project the school chooses.
Wandrer.earth - 'every street' completion with area leaderboards
Gamified exploration platform that ingests Strava activities, compares against OpenStreetMap road/path data, and tells users which streets in their city/neighbourhood/county they haven't yet covered. Awards milestones at 25/50/75/90/99% completion of geographic areas. Includes public leaderboards by area showing top Wandrers for each city, neighbourhood, county.
Decidim process-groups + Barcelona/Helsinki/NYC participatory budgeting district tiers
Decidim's 'process groups' feature is explicitly designed for grouping parallel participatory budgets per district/neighbourhood. NYC's PB ran in 30 of 51 council districts in 2021-22, each with at least $1M to spend, residents drop pins on a map to pitch ideas. Helsinki's OmaStadi splits city budget by area (Itäinen, Eteläinen, Pohjoinen, etc.) with separate ideation, deliberation and vote per area.
WeWard - Neighborhood League
WeWard rewards walking with 'Wards' (redeemable for cash/vouchers). 'Cards' are local geo-pinned waypoints (~500m from home) acting like a treasure hunt. Users can form friend leagues and 'develop a community of walkers in their neighborhood'.
