other ecology-oriented program (sorry, but I can't remember what it was) that mildly heated biochar actually DID do a lot of good. And that this not only sequestered a fair bit of carbon over a long period, but added good resources to the soil. Admittedly, it did occur to me that this would be restricted to local efforts, as it would be a logistical nightmare to try to have any sort of centralised facility generate this "product" to transmute it from problem waste to useful soil additive. And yes, as I was reading the article I was hoping to see that there was some sort of actual carbon being put into the soil, rather than just some sort of cosmetic trading system. I kept hoping to see something like that, and then gave a little sigh of disappointment when you clarified that aspect too! Sigh... Seems again that we have no simple answers to complex problems. I'll remain hopeful though that we can come up with a wide array of small and helpful initiatives that will help turn the tide on our carbon exhalations. Many people adopting small changes might end up being as important as large government driven programs. I'll keep on resisting the urge to buy a big plasmaTV!! And I just got solar PV installed on my roof. If it is the study I'm thinking of it would have been Paul Blackwell's work, worth looking it up. He did find that some biochars worked on some soil
