Evidence

Peer-reviewed

Geography

International; Europe-heavy practitioner sample

System

Food systems and environmental assessment

## WHAT THE EVIDENCE SAYS

A survey of 79 life-cycle assessment practitioners found rebound effects regarded as relevant but seldom modelled, while assumed reductions in upstream production were more routinely included. Missing data and methodological guidance were major obstacles.

## WHY IT MATTERS / OUR READ

A food-waste programme may alter spending and markets after food is saved; impact estimates should disclose which behavioral feedbacks are excluded.

## CAVEATS / UNCERTAINTY

Convenience-sampled self-reports, predominantly European academic perspectives, are not direct tests of actual carbon reductions.
