Burial Ground In England

I found this burial ground called Sun Rising Burial Ground and Nature Preserve, located in Britain. It seems that cremation is not "Green" and they allow for it, but gently discourage it. I've not run into this argument, although I've read about the "Green Burial Movement" yet must have really been out to lunch not to understand that there are such large cons that accompany cremation process.
