Step 2: Identify effects and indicators

This book explains how to identify and select the effects you will assess as well as the relevant indicators.

1. Effects and indicators

Simplified example of clustering in an effect/indicator treeStep 2 involves identify the effects assessed, along with the indicators that are used to describe them (ideally all of the measures’ potential effects should be reflected).

Clustering the effects (i.e. sorting them into economic, social and environmental categories) can ease communication of the results and facilitate the steps that follow.

Effects can be assessed using quantitative data (if available) or qualitative data (if sufficient data is not available or would require disproportionate effort).
