There are typologies which separate a priori those involved in the discussions of urban environmental projects according to whether or not they belong to an ecology group or even whether they belong to a “deep green” or “light green” group. The research showed that the typologies mentioned above are not enough to understand the contributions from the participants. Another typology is proposed.
