Dear Ron
You mention $16 and $27 per tonne CO2 equivalent. I presume you are referring to a payment that one would receive when showing that one has earned a tonne of CO2 equivalent.
[RWL: Yup - examples only - hopefully larger.]
# Prices seem to vary all over the place to purchase carbon credits. What is the present price that a biochar producer could expect to receive as a carbon Credit for the biochar he produced? It is one thing to hope for future price increases for Carbon Credits, but is that realistic? Would you perhaps have a graph that shows the price trend for CarbonCrdits that you could share with the Lists?
1: Where would one apply to get such payments? [RWL: Anywhere one can. Numerous stove promoters on this list already getting some.]
# OK!! Can you tell the Stoves and Biochar Lists where they could apply to get Carbon Credit payments for the biochar they produce?
2: Who would be eligible to receive such payments? [RWL: Anyone who can prove they deserve them.]
# That makes sense.
3: What conditions must be met, before the payments would actually be made? [RWL: Whatever is acceptable to the presumably willing buyer of the credits.]
# That does not make sense at all! Surely there must be some rules or standards that must be met to ensure that the Carbon Credits are real. If not, then the entire system is open to fraud.
I am concerned that with the state of the World Economy, Governments will lose their interest in longer term Climate Change Concerns, and would put their priorities on addressing short term and more immediate concerns. [RWL: We disagree.]
# What is your basis for disagreement? Kyoto seems to be dead in the water. At the last meeting, I believe that most Governments said "We will do something about controlling CO2 emissions sometime after 2020, but we will not say what we will do, and when we will do it." Is this a reasonable summation? If you feel not, what would you feel is?
What are your views on the future of Carbon Credit payments? [RWL: They will slowly creep up in price (maybe in time to do some good). Biochar credits from char-making stoves look like the easiest to sell of any.
# The recent report on the important impact of Black Carbon on climate change would seem to reduce the relative importance of the CO2 parameter. As I understand it, most "generally accepted Climate Change Models" were calibrated under the assumption that BC was a minor or insignificant factor, and the model factors were adjusted to relate observed temperature rise to anthropogenic CO2. Now that BC could have a "forcing effect" perhaps 2/3 as great as the present forcing effect attributed to CO2, recalibrating the models to reflect the increased importance of BC will inherently diminish the importance of CO2 as a factor in CAGW (Catastrophic Anthropogenic Global Warming). Accordingly, it would seem reasonable to project a significant decline in "Carbon Credit Revenue" to biochar producers. Does this seem reasonable? If not, why not?
# Concerning carbon credits for biochar from char-making stoves, would you have an approximate idea of the value of the carbon credits per tonne for such biochar? Would you have an approximate idea of the annual tonnage of biochar that is sold in connection with a carbon credit payment.
# As we all know, "adequate carbon credit payments" could lead to a huge increase in biochar production and use. However, if it is unreasonable to believe that "adequate carbon credit payments" will be available soon, then stoves and biochar must rise on their own inherent merits, without such support. Holding onto a false hope can only result in disappointment.
Best wishes,
Kevin

Thanks very much.

Dean and list:
Tami's is one huge report (232 pages in a major journal sounds like a world record). I spent quite a few hours today trying to grasp the topic - and know now I had better give up. The Black Carbon problem is going to take experts like Tami to bring its importance into the world of stoves. There may be an argument that if a stove can prove $16/.tonne CO2, you might have a chance at proving up to (or even more than?) $27/tonne CO2e, if you are in the right place on the globe. (These numbers based on numbers given in terms of W/sqm.) I recommend casual readers getting quickly to the figures at the extreme end of the report/paper. There is a lot of useful numercal geographic and sources comparisons there.
As Crispin has indicated the intentional large scale annual burning of large parts of Africa look like a good place to instead harvest and get useful energy and biiochar instead (through stoves and more).
Congratulations on arranging to have Tami be the ETHOS key-noter. I think she may have been at the first!

Dear Friends,
Tami is the keynote speaker at ETHOS this year and it will be interesting to hear what she's been learning!
All Best,
Dean

Dear Friends
A new and I would say major major paper on the atmospheric impact of black carbon particles is available for download. We know at least two of the authors here on ‘Stoves’. Profs Tami Bond and Philip Hopke (the aethalometer builder who said he was a minor contributor) are frequent contributors on the subject of emissions testing.
The paper is important because it is the first really detailed examination of the effects of atmospheric heating by Black Carbon (BC).
The abstract is at http://onlinelibrary.wiley.com/doi/10.1002/jgrd.50171/abstract and the paper is at
http://onlinelibrary.wiley.com/doi/10.1002/jgrd.50171/pdf
It is not behind a paywall but it is large (40 MB). Times to get your hands dirty with BC!
Regards
Crispin
