Long but compelling viewing.
I’m keen to hear from our resident biochar climate change gurus on biochar review methodology, ranking and placement under ‘food’ when it could also reside under energy, land use and materials.

In his presentation, they declare v.conservative approach to measurement. Should the biochar community of experts be engaging more closely with this initiative?
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.
