There is still a round-a-bout way of getting one.

HSBC Offshore Premier clients (that means banking in Jersey and having at least GBP 100,000.00 worth of business with them), still get the green IDC and IEC without annual fees.

But bear in mind that AFAIK green Amex charge cards don't "come with" Membership Rewards. Although you may not pay for the card as such, you would still have to pay some 20.00 bucks a year per card to earn points.
