[Stoves] ESPs for stove solidfuel PM2.5?

[Anderson, Paul]

Terry,

The plan was released in 2013.   Is there any info on actions, roadblocks, successes, goals met, etc?

Anyone for some light Sunday reading? Here is the Kenya Country Action Plan from the Clean Cookstoves Alliance Kenya - http://cleancookstoves.org/resources_files/kenya-country-action-plan.pdf

If anyone feels like sending your thoughts or feedback I'd be happy to pass them along at the next meeting we go to or you can email them directly as well on

Best,

Andrew:

You say "targets are needed". What targets and who needs them where? Why should I concede that what WHO - and the cabal of "implementation scientists" - WANT for everybody everywhere is indeed what is needed by poor peoples and their governments?

The WHO 25µg/m3 guideline<http://apps.who.int/iris/bitstream/handle/10665/69477/WHO_SDE_PHE_OEH_06.02_eng.pdf> for PM2.5 is for 24-hour mean, with 10µg/m3 as the annual mean. For our purposes, let me only note that

(a) this value need not be in every spot for everybody; the definition of location, measurement protocol, and averaging methods matter;

(b) there is zilch evidence that the annual mean is reported in even 1,000 representative households or a representative neighborhood, city, district, leave alone separately from cooking fuels and other sources (Kirk Smith has no skeletons in his closet);

(c) the assumptions of equitoxicity, "no safe threshold", and uniform cohorts across the world and over time, are simply untenable; (as also the assumptions and derived form of the Integrated Exposure Response, which came roughly a decade after the guideline); and,

(d) PM2.5 is an indicator of pollution because of its co-emission with other pollutants such as NOx. (How much NOx from cookstoves, Crispin?)

There is no basis to drag WHO into cooking and heating stove business. There is no there there. We are here to serve people, not pundits.

WHO "guidelines" are of zero value for air quality management (AQM). It has "interim targets" for annual average and daily maxima, but again of no consequence. It has SDG targets for energy and health which are in complete contravention of our work on cleaner combustion of solid fuels because it has bought into Berkeley/EPA/CCA lie that solid fuels are by definition unhealthy.

Now that GACC is dead, the time has come to kill the ISO TC-285 circus and rubbish the WHO/Berkeley gangsterism. (I hate to personalize the distasteful propaganda in Kirk Smith, who I agree with in many respects, just that he has to be held responsible for his intellectual air pollution.)

Let's see if people on this list can take control of the cookstoves debate, even if they cannot produce usable, marketable cookstoves that are contextually designed and promoted.

Who should give a hoo(t) about WHO?

Let's not be distracted by the red herrings. WHO air quality guidelines (AQG) for PM2.5 and PM10 are purely adventurism of self-professed pundits. WHO has neither the jurisdiction nor the competence in air quality management (AQM) and of course no money to finance AQM development. It has become the bag carrier for UN Foundation, Gates Foundation, and USEPA (which has probably ended this last September, at least as far as cookstoves and ISO TC-285 chatterbox are concerned)

We here should forget about WHO or, if we have the druthers, improve our work and challenge the WHO directorate of social and environmental health if we can't ignore them. The elements of challenge, apart from the case I laid out above - there is no there there, just vacuous, incompetent babble outside WHO's mandate - are simple:

1. The  are not "standards". (AQS) Even leaving aside the issue of compliance and enforcement, standard-setting is an art with interplaying colors of science, law, economics, and capacity, all contextually determined. To pretend otherwise means a contempt of half a century of regulatory battles in the rich, and better-informed, world.

2. WHO has borrowed these AQS from USEPA and such other entities, who in turn use the AQS, with air transport modeling studies, to develop fuel bans or source emission standards, depending on location and associated demographics, meteorology, and technology status. Again, this has the same colors with different contextual pictures. But unlike them, WHO has no authority - nor the competence - to define fuel bans or emission standards. What it did in its 2014 report Household Fuel Combustion Guidelines - Solid Fuels (HFCG) is a ridiculous overreach, on the strength of ludicrous "literature reviews" on invalid or incomparable cohorts, that consultants like Kirk Smith and Sumi Mehta churned out. The literature reviews and the GBD "relative risk" computations, combined with contemptible "room modeling" by BAMG got you the TC 285 emission targets, on the one hand, and gave license to Kirk Smith to pronounce "not truly health protective" and "no stacking".

All this has been a waste of tie. The only proper means of moving the technology frontier is to develop low-emission rate stoves that make a significant measurable contribution to improving the quality of air breathed by specific populations.

Yes, I am in favor of fuel bans if such technologies are not available. But not only are cleaner combustion technologies available, there are means of venting, filtering, extracting that can be adapted to different structures and neighborhoods.

Fuel bans or subsidies I am reasonably equipped to evaluate. I have even had some effective contribution there. What we next need is to challenge WHO and CCA to come up with (i) the evidence of daily and annual exposures to solid fuel cookstove pollutants and corresponding disease incidence, (ii) establish causality and hence avoidability, and (iii) air quality modeling for daily, monthly, seasonal variations according to geographies, fuels, cohorts, that can inform air quality management plans. (If they continue to kill people by GBD assumptions, I demand lifelong exposure data for roughly 3 billion people from 1986 to 2026.)

Time to turn the heat on. So those who can't cook get out of the kitchen and stop feasting at the meager foods of the unfortunate.

Any takers?

...but is 25µg/m3 the target we should be aiming for, I realise this is the level the World Health Organisation say but how practicable is it given your next paragraph?

This is very much what I see at home, around 5µg/m3 quiescent state but when I walk into the room I notice a temporary rise to over 10µg/m3, some of this may possibly be from particulates released into the local atmosphere by *my* chimney as I heat with wood, as well as background particulates and dust from my working.

In other words they are willing to spend more money to clean up emissions instead of preventing them in the first place.

Yes I cannot see this being a sensible use of the money, nor fitting filters like a diesel car has to have now in UK (they have a back pressure which could not be overcome with natural draught).

This will be coal burning then?

So is it a sensible target, 0.42g/kg of fuel burned? If we assume 150% excess air (or more as long as it's known) we can relate that to a particulate concentration in µg/m3 of the stack emissions.

...and yes Nikhil I realise I am being deterministic where you consider it is meaningless but I still feel targets are needed.
