[Stoves] Clean stoves and LPG planning (India and Haiti)

Anil says, "all fuels are dirty - only excellent combustion makes them
clean. <http://nariphaltan.org/diesel.pdf> "

Depends on what the meaning of clean is. In my view, the meaning is
contextual, not just at the micro level but nationally.

Beginning with UNDP (as I recall it) and most recently coming to Obama's
"Clean Power Plan", the term has been corrupted to no end. "Clean" is
supposed to be "no fossil fuel", which is plainly stupid; the efficiency of
fossil fuel use has improved dramatically in various steady applications,
at least in the industrialized and industrializing countries, with the
result that "more complete combustion" emits much less non-CO2 pollutants
(with the result that CO2 per unit kg input goes up, which is good from
both health and climate points of view).

And then "clean" is supposed to be "renewable", which raises another raft
of questions. Many renewables require land and capital, which are not
"renewable" and some like biomass require much more water and labor, which
are not entirely "renewable".

Then consider the evidence I cited in my response to Ron last night -- from
the Nature article he sent and the black carbon link I added -- that
traditional biomass combustion emits far more climate and health pollutants
 in India than coal.

Definitions matter. Measurements matter. Relative magnitudes matter.

Emission inventories are manufactured, but my rough sense from the rather
delightful "640 districts" study is that meteorogical data can provide a
check on how emissions translate into contribution to concentrations.
(There is far more to PM2.5 or to even small-scale biomass and coal
combustion than household cooking, which is why I find this "household
energy consumption" mania rather meaningless. Besides, the underlying data
are poor, poor, poor. Everybody in the modeling world knows that.)

Of course, coal and solid biomass can be combusted "cleanly" - in popular
understanding - not just in power plants but also in direct thermal
applications by small users. We know that from fuel chemistry, combustion
chemistry, and air chemistry.

US consumption of biomass energy in 2016 <http://www.eia.gov/renewable/> is
estimated to be 4 quads (quadrillion Btus), which is about 100 mtoe
(million tons of oil equivalent). Not sure if it includes charcoal and
campfires. It is more than all other "new renewables" (excluding large
hydros) combined in the US.

And I am guessing that is about the same as all small-scale (non-power)
biomass energy consumption in India - 62.5 m in households (0.5 ton biomass
per household per year x 0.5 mtoe per mt biomass x 250 m households), rest
outside homes.

Plus non-energy small-scale anthropogenic combustion -- burning crop
wastes, leaves, urban solid biomass.

The deceit of ISO IWA is that the chemistries in actual cooking conditions
do not matter, that "stove testing" with WBTs under tightly controlled fuel
chemistry and fictional "box models" have *predictive values* for air
pollution exposure and incremental "health benefits".

Ignoring all non-household solid fuel use use, combustion of other fuels
(industrial, transport, commercial, even households) that emit pollutants,
and natural sources of PM2.5.

That is insane. (Cecil and Crispin might have milder words.)

There must be NO assertion of "clean" based on stove testing. I know that
is a radical statement, but the time has come to sit back and take stock of
this farce going on for some five years now. It has nothing to do with air
pollution, nothing to do with exposures and dose-response ratio in any
cohort-specific manner, just about nothing to do with anything other than
cooking up some alternative GBD numbers. (Which is not a bad idea in
itself. Stay tuned.)
