Pulse Methodology v2.0

How we score city sustainability

The CityPulse Point (Pulse) system gives every city a single, comparable, transparent score from 0 to 100 β€” and shows you exactly how that number was built. No black-box AI claims, no hidden weightings.

Principles

Five rules every Pulse score must pass

These principles are the contract between Cittopia and any city, citizen, or grant reviewer reading a score.

Transparency

Every score traces back to a named indicator and a named data source. No magic numbers.

Comparability

Indicators are normalised so cities of different sizes and shapes can be compared fairly.

Fairness

Population, structure, and data availability all factor into how a score is built.

Scalability

Works for cities with rich live datasets and for cities still uploading their first CSV.

Auditability

Anyone can review the math. Every figure is exportable for grant or academic review.

Architecture

Two scored components, one trust layer

Performance is the city's structural sustainability footprint. Participation is the citizens' active uptake. The trust layer says how confident we are in both β€” without affecting the headline score.

Component A
70%

Performance Score

Structural and operational carbon performance. Built from six categories, each scored on 0–100 cohort-percentile and averaged.

    Component B
    30%

    Participation & Adoption

    Citizen-side proxies for sustainability uptake. Population-adjusted so a smaller town with high engagement isn't unfairly outscored by a megacity.

      Trust & Data Confidence β€” separate, never hidden

      Each score is shipped with a confidence indicator β€” % of categories backed by measured data vs filled by neutral defaults. It does not change the score, so cities can't game it by under-reporting. Citizens see "High / Medium / Low" alongside every published number.

      The six performance categories

      What each category actually measures

      Each card shows the category, the indicators feeding it, and an honest note about what we still can't measure today. Direction labels show whether higher or lower is better.

      Fairness β€” population tier weighting

      Smaller cities aren't penalised for their size

      Per the Pulse spec, the participation component contributes more to a small town's score than to a megacity's β€” because 50% of a small town engaging in recycling is a different kind of achievement than 50% of a 5-million-person megacity.

      City tier Population range Participation weight in final score
      Tier badges

      What the badge next to a city means

      Badges are awarded against the same scale for every city. They feed into the funding-prioritisation logic (top performers get reward grants, low performers get priority access for transformation grants).

      Standards we align to

      Why this isn't a parallel universe

      Pulse is built on top of the frameworks that EU funding bodies, climate networks, and national statistics offices already use β€” so cities can reuse what they already report rather than maintaining yet another dataset.

      What we don't measure yet

      Transparency includes admitting where the system is weak. None of the items below invalidate the score β€” but they shape how confidently you should read it.

      Known gaps in the current data foundation

      • Direct COβ‚‚ emissions at city level β€” Eurostat Urban Audit doesn't publish this. We use waste-per-capita and car-density as proxies until municipalities upload GPC inventories.
      • Air quality β€” no live PM2.5 / NO2 feed yet. We approximate with green-space density and inverse car-density.
      • Climate Policy & Targets β€” cannot be auto-scored. Requires a verified municipality to upload their SECAP / Covenant of Mayors plan.
      • Building energy classes β€” sparse at city level. Current proxy is household-per-dwelling pressure. Phase 2 will accept municipal building-stock uploads.
      • TΓΌrkiye's data ends in 2004 β€” the country stopped reporting to Urban Audit. Ankara, Istanbul, and Izmir scores reflect this with low confidence.
      • Participation proxies, not real data β€” until cities connect their transit & recycling APIs, citizen participation is approximated from infrastructure (bike-parking, EV chargers, transit stations) rather than measured behaviour.
      Governance

      Built for academic and EU validation

      The Pulse methodology is intended to be governed through a Scientific Consortium of universities and city networks β€” for periodic review of indicators and weights, bias and uncertainty analysis, and publication of findings.

      All raw data, normalisation choices, and per-city audit logs are exportable so any grant reviewer or research team can independently re-run the math.
