Check out this blog post[0] for data on at-home decaffeination by steeping. It requires a much longer steep than most people think. Related note: An interesting paper[1] found "no observable trend in caffeine concentration due to the variety of tea", meaning that green tea doesn't necessarily have less caffeine than black tea, for example.

Green teas have about the same amount of caffeine. If anything, they'd have more since they are less processed. But as prepared, they have a lot less because they are steeped for shorter periods of time and with cooler water.

  > If anything, they'd have more since they are less processed. white tea seems to say otherwise..

    White tea has such little caffeine because it is steeped for only a few seconds at a low temperature. Again, it's the difference in preparation methods rather than the leaf.
