At 24, I was recently diagnosed with osteopenia.
I know you've said that soda can cause calcium to be leached from your bones because of the phosphoric acid in it, but does this apply to all carbonated beverages?
What about sparkling water?
I want to make sure I'm getting enough calcium from my diet.

As you state, sodas can cause calcium to be leached from bones due to the presence of phosphoric acid (if this is news to you, please see this post for details).
Not all carbonated beverages contain phosphoric acid; you'll usually find that particular ingredient in cola beverages (rather than lemon-lime sodas or club sodas).
In any case, it is always wise to take a peek at the ingredient list for reassurance.
Keep in mind that phosphoric acid in soda calcium leaching is only a problem if your calcium consumption is insufficient.
Someone who meets their daily calcium requirement and drinks one can of soda a day is in a very different -- and much less worrisome -- situation from someone who only gets 40 percent of their daily calcium requirement and drinks three cans of soda on a daily basis.
