Make coffee, not trash is motto of Eko Brew, the maker of a reusable filter for single cup coffee brewing machines.
You have to be willing of course to take that extra step of filling filter with your own coffee (which in turn allows you to choose which coffee to drink) and rinse filter between uses.
How many single cups end up in landfills after use on a yearly basis? I don't know.
It reminds me of efforts in Japan to combat waste created by huge amount of chopsticks discarded by recycling them.
