To some degree it probably doesn't matter. If you send $ on carbon offsets that don't offset carbon, you're still imposing an extra cost on releasing carbon and thus incentivizing yourself to release less. Basically a self-imposed carbon tax. Obviously it would be even better if the $ went to actual carbon sequestration, but the program would presumably work to some degree if you just gave the $ to some totally unrelated cause (which seems to be the solution UC has settled on).
