 Okay, so we just presented on work that we did that was funded by the Global Alliance, and we've been working on it for about three years, looking at the sustainability of wood fuel extraction as compared to supply on a spatial geographic basis. It was well attended and I was happy that we had a good showing. And just to summarize the results, we find that about 30% of overall global wood harvest is unsustainable, and that sounds like a lot, but it's actually quite a bit less than most people have been assuming for many, many decades, 60% or 70% less. I'm a little ambivalent about the results because it means that cookstove interventions that I support are actually earning fewer carbon credits, or should earn fewer carbon credits than they do, but at the same time it's important to get accurate information out there so that people don't have misplaced expectations about what stoves can do.
