Assessment Challenges

Impact assessments build on knowledge about causalities. For some effects, though, this knowledge is still very limited, which makes it challenging to quantify impacts. Ignoring these effects may, however, lead to distorted results: Just because we cannot properly model an effect, does not mean that it doesn't exist! 


These pages describe the three such effects: Rebound Effects, Leakage Effects, and Indirect Land Use Change.
