What is the UCA? What are the UCA materials? What are the outputs? What are the steps of the UCA? Part 1a: Material Flow Accounting Defining urban context Data collection Step 1: Select if materials are extracted, imported and/or exported Step 2: Determine if data from the SCA can be reused Step 3: Find local data to satisfy your data needs Step 4a: If you don’t have or can’t find local data, try to use provided data sources Step 7: Determine which waste treatment methods exist within your municipal boundaries Step 8: Determine if you have data for the waste categories and fill in the amounts Data processing Step 4b: Downscale the data from Step 4a with the correct proxies Step 5: Fill in your final values in tonnes for two years Step 6: Note meta information of the data Part 1b: Material Stock Accounting Step 1: Find locations, land use and floor areas of buildings Step 2: Gather building typologies Step 3: Determine building typology’s material composition Step 4: Calculate material stock and spatialise it Part 2: Measuring indicators Part 3: Assessing Circularity Step 1: Data gap and quality analysis Step 2: Interpretation of indicators Step 3: Assessing the circularity of the city UCA Report Sector-Wide Circularity Assessment – Handbook Why should cities carry out the SCA?

Step 1: Data collection Layer 1: Urban context Boundaries Population Economic activities in the city Policy documents Land use Layer 2: Sector economic activities Value chains GDP and/or GVA per NACE code Employees per material Actors Geo-localisation of infrastructure Layer 3: Material flows and stocks Extraction / harvesting Manufacturing Construction manufacturing Biomass manufacturing Use Stock Waste Construction waste Biomass waste Imports and Exports Step 2: Data processing Step 3: Data analysis Generation of Sankey diagram Selection and calculation of indicators Background and glossary of indicators Generation of insights Insights from Sankey diagram Insights from single datasets Insights from data quality assessment Insights from indicators SCA Report

How to analyse data

The way how data is analysed is described in the respective parts for the SCA and UCA methods:

  • SCA: Step 3: Data analysis
  • UCA: Part 3: Assessing Circularity

However, what they have in common and which gives reason to this section is:

  • How to benchmark indicators
  • How to interpret the circularity dashboards
