The above posters seem to have got it spot on
I recently had a chance to quiz BA's environment chap about this - he said that the ETS suspension is so that the ICAO meeting in October next year can come up with a workable solution.
If not, ETS will be re-introduced in some form, apparently.
Mike Echo: we also discussed the situation with the Chinese and US airlines refusing to comply, and he agreed with my suggestion that, obviously, any scheme where there is widespread dissent and disobedience is unworkable; you can't ban / impound every non-EU airline / aircraft for something like this.
If ETS is re-introduced, it looks like it will be intra-EU only, for the time being, as a first step. Otherwise, it will defer to ICAO.
