Green and social considerations are closely connected. Accepting this in theory is rather straightforward; enacting it, less so.
Carbon markets are a case in point. Initiatives aimed at pricing carbon dioxide emissions so that polluters would find it more costly to continue with business as usual are effective when the price they assign to carbon is high enough to prompt a switch to green. That switch, however, has economic and, therefore, social repercussions that are harder to manage.
