<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US">I am very interested that you think that CO from coal-fired cooking stoves is a measurable pollution problem anywhere. It might be in the vicinity
of the fire, but in the ambient air? That would be news. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US">It should be obvious (but may not be) that if the coal were burned with extremely low PM and CO emissions, the perception and reality of using coal
as a domestic fuel would be changed dramatically. For those who are interested in getting extremely poor people to reduce their emission of CO2 annually, a fuel-efficient coal stove would also be of interest.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US">Thank you for noting and providing some numbers on the increase in coal use as a domestic fuel in a tropical country. There is often a broad assumption
that hot countries use biomass exclusively for cooking. You will no doubt be impressed that in some places the portion of people using coal for at least some of their cooking approaches 100% in winter.<o:p></o:p></span></p>

<p class="MsoNormal">Coal, as a fuel is used widely for domestic cooking in many regions of India, which contributes significantly to the Carbon Monoxide (CO) and PM2.5 levels (both indoor and ambient). Chandrapur, Maharashtra (India) which has been identified
by the Central Pollution Control Board (CPCB) as one of the most critically polluted cities of India (CPCB, 2016) is one such area where coal stoves have created problem to the air quality. <o:p></o:p></p>

<p class="MsoNormal">According to the Environmental Performance Index Report, 2014 prepared by Yale University, the number of people using solid fuel as cooking fuel has increased greatly. The absolute number of people using solid fuels (biomass and coal) for
home cooking and heating has roughly doubled from 333 to 646 million from 1989 to 2010 and this particular number is expected to rise substantially by the year 2020. According to Census, 2011 data more than 3.5 million people still use coal as their primary
fuel for cooking. As per provincial reports of Census of India, population of Chandrapur city in 2011 was 3,21,036. The estimated use of Coal in Chandrapur is in approximately 11,769 households.<o:p></o:p></p>
