[Stoves] Advocacy action: ask the GACC to stop promoting the WBT

Thu Jan 26 21:41:40 CST 2017

Dear Rebecca

The Adapted WBT makes a better calculation of the charcoal and how it is handled in order to give a more realistic performance of charcoal burning stoves (which the WBT doesn’t do well unmodified).

We could ask David Beritault who created it (as far as I know). He is very good on technical and conceptual analysis. I have never used the test myself because it leaves in place dozens of systematic errors from the WBT. The results it gives for lab tests are closer to field tests than WBT lab tests. That is why they used it in Cambodia.

Hi Crispin,

What attributes does the Geres WBT have that produce "better results" than the GACC WBT?  Like wise for CSI Indonesia test method.  Please be specific and detailed if possible.

Many thanks,

Rebecca
