Indicator Topics

The UNI is structured around 30 indicator topics nested across six themes. The indicator topics allow for the analysis and monitoring of different aspects of urban nature. Thanks to the flexible nature of the UNI, and given potential capacity constraints, cities are recommended to implement at least one indicator topic per theme.

  • Material Consumption

    Estimate consumption of goods per person by measuring waste produced.

  • Harmful Harvest & Trade

    Assess trade that directly harms species or ecosystems, whether legal or illegal.

  • Greenhouse Gas (GHG) Emissions from Energy

    Estimate greenhouse gas emissions per person that result from energy use.

  • Unsustainable Diets

    Measure the sustainability of diets according to land use and overharvesting concerns.

  • Water Withdrawal

    Measure freshwater consumption against locally sustainable levels.
