Visit this web site, learn some facts, look at the 20 pages of stoves (List of EPA certified stoves) that already meet the Phase 1 standard of (4.5/7.5 grams per hour) (catalytic/non-catalytic). You will also see a handful of mostly pellet stoves that already meet the five year Phase 2 (1.5 grams per hour) standard.

The Phase 2 1.5 grams per hour is a tough but not impossible standard. However, it has nothing to do with the stove you own now and forever, or the one you may buy up to five years from now.
The "fact" that decomposing wood or burning wood is carbon neutral is not relevant to particulate emissions. I've never seen smoke rising from a rotting log.
