I agree, John, that there should be fees on all greenhouse gas
emissions, but I especially focused on aviation, since there are few
ways to fly without causing emissions, so it seems a suitable place to
start with the idea to make polluters pay for the cost of cleaning
things up.

Good point Andrew, fees may contravene the Warsaw convention - that's
why all this should be worked out at C4 (the Copenhagen Climate Change
Conference, later this year).

I propose that a new treaty be negotiated at C4 that includes aviation
emissions. I suggest that such emissions can best be offset by
carbon-negative activities such as carbon air capture and storage
(CAC&S).

Such an arrangement would help get CAC&S as an industry off the
ground, and further innovation and economies of scale will then bring
the cost of CAC&S down substantially, which would be in the interest
of air carriers that have to offset their emissions.

Fees could be imposed on conventional jet fuel at the airport where
refueling takes place. The proceeds could then be used to fund CAC&S
which could take place anywhere in the world. Government doesn't have
to operate all of this, but it should check that gases are indeed
captured and kept out of the atmosphere (and, I should add, the
oceans).

Air carriers could also fund CAC&S facilities in advance, which could
give them credits equivalent to the fees they would otherwise have to
pay. Since safe storage is a major part of the operation, I can see
that capture could well take place close to, say, limestone deposits
that could soak up the captured carbon. Market mechanisms can best
sort out such details.

Alternatively, captured carbon could be reused in ways that replace
fossil fuel usage. In that case, there won't be financial assistance,
since there will be no storage. Yet, it will be financially attractive
since the industries that buy the carbon would save on the emission
fees they would otherwise have to pay if they bought CO2 that was
produced from fossil fuel. I've discussed that in more detail in the
article at:
http://www.nowpublic.com/environment/funding-co2-air-capture

The question is what will be the effective way to reduce greenhouse
gases. In part, that will depend on what's politically most
attractive. I can see the logic of making polluters pay for the cost
of cleaning things up. Extending that logic back to the past would
make western countries also pay for past emissions by funding extra
air capture, but all this should be worked out at C4.

Generally, I believe the best way to go is to reach a broad commitment
at C4 to reduce greenhouse gases, while leaving it up each country to
decide how best to achieve the agreed reduction targets. That
agreement could be backed up by the threat of fees imposed on products
imported from countries that fail to reach their targets, and the
proceeds of these fees could then be used to fund CAC&S.

Cheers!
