I'm trying to fix that, and I hope you can help!</div>
<div><br></div><div>I mean, yes, I can wave my hands about PM and CO and four million deaths!</div><div><br></div><div>But how many deaths (or DALYs) do you avert per stove? Or per 10,000 stoves? Or per 100,000,000?</div>
<div><br></div><div>I thought it would be an easy question to answer, but it's turning out to be quite tricky to even ballpark.</div><div><br></div><div>Here is one interesting source. This is from the very recent webinar on Kirk Smith's HAPIT tool. </div>
<div><br></div><div><a href="http://www.cleancookstoves.org/resources_files/hapit-results-rwanda.pdf" target="_blank">http://www.cleancookstoves.org/resources_files/hapit-results-rwanda.pdf</a><br></div><div><br></div><div>
This report considers 25,000 households.</div>
<div>If you provide all of those households a rocket stove, you save only 0.75 lives per year.</div><div><br></div><div>If you take the GACC's target 100,000,000 households, that would mean</div><div><br></div><div>0.75/25000*100000000 = <b>3,000 lives saved</b> worldwide annually.<br>
</div><div><br></div><div>What am I missing there? This seems so small.</div><div><br></div><div>Some speculation:</div><div><br></div><div>Kirk Smith mentions in the HAPIT webinar that even a small amount of PM2.5 is still harmful. Perhaps biomass stoves just don't get the number low enough?</div>
<div><br></div><div>I think this would fit with the chart in the linked PDF that shows that stoves only reduce deaths by <5% for indoor air pollution. A few times in the HAPIT webinar, they mention "a lot of lives are still left on the table."</div>
<div><br></div><div>This also seems to agree with something I found in Christian L'Orange's dissertation:</div><div><a href="http://digitool.library.colostate.edu///exlibris/dtl/d3_1/apache_media/L2V4bGlicmlzL2R0bC9kM18xL2FwYWNoZV9tZWRpYS8yNDYyOTQ=.pdf" target="_blank">http://digitool.library.colostate.edu///exlibris/dtl/d3_1/apache_media/L2V4bGlicmlzL2R0bC9kM18xL2FwYWNoZV9tZWRpYS8yNDYyOTQ=.pdf</a><br>
</div><div><br></div><div>Figure 33 shows that Envirofit G3300 stoves only have a 3% (or so) impact on "Adjusted Relative Risk" (of death)</div><div><br></div><div><br></div><div>Please do not worry about hurting my feelings in correcting these numbers. Am I thinking about this the wrong way around? Have I punched the numbers in incorrectly? </div>
<div><br></div><div>Also, I would be very interested to read more good papers on health impacts for stoves. It is all really quite interesting work. I feel bad that I didn't look at it sooner.</div><div><br></div><div>
