I think a veil/glaze of black or dark brown will work. If you don't want to make things too dark, maybe try a lighter red brown...this should neutralize the green without darkening it.

I'm with Adrian - If you're trying to 'grey' a colour then add the complimentary (Colour on opposite side of colour wheel) so adding something from the red spectrum will kill the greeness (Is that even a word?)
