Will one husband like the environmentalists and not like Scrooge? (10)

I believe the answer is:

economiser

'will one husband' is the definition.
(as a verb, 'husband' can mean use economically)

'like the environmentalists and not like scrooge?' is the wordplay.
'like the environmentalists' becomes 'eco'.
'and' says to put letters next to each other.
'not' becomes 'no' (I've seen this in other clues).
'like scrooge?' becomes 'miser' ('miser' can be a synonym of 'scrooge'. I am not sure about the 'like' bit.**).
'eco'+'no'+'miser'='ECONOMISER'

I've seen this clue in The Guardian.
