A tax on disposable plastics is probably pretty doable.

The worst part is that K-Cups solve a non-existent problem. Their advantages over your normal office percolator is that it takes less work, nobody has to make it, they don't collect rancid coffee oils that nobody bothers to clean out, and the beans are marginally better than the garbage most offices are buying. You can also stock a variety of flavors without having to commit your entire office to drinking a pot of artificial cinnamon flavoring.

But you could solve all of those by just using instant coffee and a water boiler! Just about every other country in the world has figured out how to make decent enough instant coffee, especially in Asia. But for some reason, America is still stuck with Folgers crystals.

That's actually where I'd start if you want to have an impact via guerrilla marketing. Convince your office to switch over to something like Sudden coffee or even the Starbucks Via packs. No, it's not as good as your fancy third-wave coffee spot around the corner or even just a regular Starbucks. But it can be head and shoulders above anything a Keurig will give you.
