Presentation Title: Urban sustainability metrics: Smart-scaling for cities
This presentation was an introduction to the work of the Environmental Performance Measurement Program at the Yale Center for Environmental Law & Policy, the Environmental Performance Index. Which indicators should be measured, can and cannot be measured, and data availability were discussed and supplemented with the following questions:
- How can the scope of urban sustainability be determined?
- What types of data, measurement and indicators are needed?
- What is the best way to design a framework that can link across sectors?
- How can new data be sourced?
Key Lessons Learned
- Cities are becoming increasingly critical for sustainability, but a question remains: Are they a solution or problem for sustainability?
- Many urban sustainability indicators are not measurable, plus there is a lack of consensus on which indicators to measure.
- Comparability and bench-marking is key to choosing data types, measurements and indicators.
- Data availability between cities is inconsistent.
Knowledge Gaps and Needs
- Typologies based on perception and quantitative variables.
- A scientific/knowledge-based framework for urban sustainability indicators.
- Urban data governance: How are decisionmakers using data? What information is needed to make improved decisions, i.e., urban sustainability?
