<div dir="ltr">Crispin: <br><br>Slow in praise, please. <br><br>According to <a href="http://cleancookstoves.org/about/news/10-26-2017-rural-cooking-smoke-is-making-delhi-air-pollution-worse.html">GACC yesterday</a>,<br><blockquote style="margin:0px 0px 0px 40px;border:none;padding:0px"><br> "One of the most surprising sources of Delhi's air pollution is the smoke coming from the millions of cooking and space heating fires outside of the city limits," said Dr. Sarath Guttikunda, Director of UrbanEmissions. "Urban areas such as Delhi cannot solve their air pollution issues without first addressing the issue of cooking, space heating, and household air pollution in the households beyond that surround them."</blockquote><br><div style="">I don't know about "first". That's a bit like saying Delhi cannot stop putting its sewage and sludge in the Yamuna (<a href="https://www.wsj.com/articles/the-worlds-next-environmental-disaster-1508511743">The World’s Next Environmental Disaster</a>, WSJ 20 October 2017) without first stopping upstream water pollution and diversions that reduce the river's ability to act as the gutter. </div><br>Besides, who has to "go first" about "addressing the issue"? The central Ministry of Petroleum and Natural Gas and the Ministry of Finance are expanding LPG distribution in rural areas, and those closer to cities may well get saturated in three years (unless LPG prices are increased, without increasing the subsidy payments). <br><br>CCF 2017 might well be the swan song for GACC. I don't know when again Dr Guttikunda would get to present his research and opinions at a global GACC event. He know well that knowing about air pollution is not enough. Why, as of two years ago, India didn't even have emission standards for coal-fired power plants. Setting "international standards" for PM2.5 in mg per MJd is a waste of time. . <br><br><div><br></div><div>Nikhil<br> <div class="gmail_extra">

<p class="MsoNormal"><span>Dear Nikhil<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I think we are getting to some fine source material. The
<a href="http://www.urbanemissions.info/blog-pieces/whats-polluting-delhis-air/" target="_blank">
first link</a> is great. Domestic stove emissions exist in a context, stoves are not pills, and a Standard has to be examined on the basis of the service standard required of that Standard. The purpose of a contextual review is to see if the Standard addresses
adequately the needs of the users. Following that, we look to see if the test methods applied address the needs of the users of those products. Capiche? It is a two-stage assessment.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>Applied to the concept of DALYs and aDALYs there seem to be three stages. The first is whether or not there could be such a thing as an aDALY, (something you have shown to be irrational) then second,
the assessment of how well the aDALY serves as a metric, then the testing of a stove to determine from its performance whether it creates the conditions that create an aDALY.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>Have I got that correct?
<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>So in Guttikunda’s contextual analysis, the aDALY created a cooking stove disappears into the morning smog like a pedicab at dawn.<u></u><u></u></span></p>
