I thank Trevor of the Biochar Listserv for introducing the topic. It is
a worthy topic for the Stoves list, also. Trevor wrote:

Thanks for pointing out these two videos. First one is 1 hr 17
minutes. And I stayed with it to the end. Very informative. Second
one is also over an hour, but in the first 6 minutes I determined that
it is a repeat of the same talk to a different group.
You should look at one of them, and I refer to the first one..
At minute 32:26 there is a list of the top 20 Drawdown ""ways"
(approaches??). Well worth studying (and is discussed in the
subsequent few slides and minutes. Numbers linke #1 (refrigeration and
AC ) is listed as 89 GT (gigatonnnes CO2e) by the year 2050, which is 30
years away from 2020 (their starting point). Correct me if I am wrong,
but that is 89 GT TOTAL in those 30 years, not 89 GT per year.
And the grand total is 1051 GT , See the summary table at:
http://www.drawdown.org/solutions-summary-by-rank
#10 is rooftop solar, at 24 GT.
#20 is nuclear (admitedly controversial) at 16 GT.
and #21 is Clean Cookstoves, at 15.8 GT
The top 20 account for about 75% of the total drawdown being
discussed. MANY other ways are in small numbers of GT. Of special
note is #72 Biochar, calculated as 0.8 GT by 2050.
This is all for discussion.
My calculations about TLUD stoves that earn carbon credits and produce
charcoal are:
1. Goal of 250 MILLION stoves by 2030, but just say it is to be by 2050.
2. Each stove earns 4 carbon credits (each is 1 tonne CO2e) per year.
That would be 1000 Million tonnes. Which is 1 GT ..... PER YEAR!!
3. Do that for 30 years and that becomes 30 GT. WHAT IS THIS?
Just the TLUD stoves for poor people could be double what is
calculated by the Drawdown book.
So, Please correct me about any errors by me. Let each Listserv do
its own discussion.
