Every restaurant is assessed against SEERO, our six-dimension sustainability framework — covering sourcing, seasonality, waste, animal products, social impact, and plant-forward cooking. Each finding is weighted by how strongly it is corroborated. The combined result is translated into a planet rating from 1 to 5.

SEERO is an acronym for Starting, Engaged, Endorsed, Recognised, Outstanding:

How a level is reached. Each level needs two things together: a minimum number of dimensions covered, and a minimum overall strength of evidence across them. A dimension only counts once its evidence is specific and substantiated — a passing mention doesn't qualify. Meeting only one of the two keeps a restaurant a level lower.

Ratings of four or five planets require human validation and, at the top tier, an external audit. Scores are based on publicly available evidence and restaurant submissions at the time of assessment.
