Since 1990 GCI has well-tempered the focus on UNFCCC-Compliance with C&C

C&C & the Rajan Carbon Tax Proposal

C&C or Doing Enough Soon Enough for UNFCCC-Compliance is like
playing in time & in tune in music in a cadential structure of 'closure'.

It means Equity Equals Survival.

*********************************

In December 1997, a C&C-based way-ahead was debated in the final session of COP-3,
with strong interest from India, China the Africa Group the USA. The United States stated,
"C&C contains elements for the agreement that we may ultimately all seek to engage in."

GCI proposed Contraction & Convergence, Allocation & Trade at COP-2 in 1995.

In 2009, Adair Turner, then Chairman of UK Climate Change Committee,
told the Parliament that C&C is the basis of the UK Climate Act
(UKCA).

Are C&C + the Rajan-Carbon-Tax-Proposal compatible? Open/download this pdf file
into Acrobat Reader. There are 42 slides in this 'heuristic', suggesting the answer is 'yes'.

Without a full-term carbon-cap, the tax is meaningless. With it however, the second key
to the structure is reconciling the tension between over & under carbon-consumers.

Indexed to the rising price of carbon and the contraction of emissions, you can keep an eye on
the closure between the 'debits' & 'credits' between carbon-debitors & carbon-creditors.

This is equivalent to contraction with immediate convergence as argued by the Government of
China at COP-15
. You can tap through the
present slides (2020 - 2040) one-by-one.


There are 42 slides in this 'heuristic'.
Each slide is identical except . . . .

[a] each slide shrinks by 1/20th of the total carbon budget weight (137.5 Gt C)
annually from 13.1 Gt C in 2020, to absolute zero Gt C in 2040.

[b] All weights (cumulative & marginal) are shown counting down for each year.

[c] The debit/credit balances expressed as global $s are shown for each year calculated
above & below the global per capita average of carbon emissions of the global budget.

[d] within this structure carbon-debitors pay into a global fund
while carbon-creditors withdraw from it.

[e] with a population base year for 2020 (7.5 billion).

It may seem 'dry' but this is quite deliberate.

[f] As with the carbon, all net calculations have been purged from these accounts.

[g] Globally aggregating any 'net-calculations' is only relevant to that absolute calculation,
which obviously has to be done first.

[h] The procedure shown, halves global emissions between 2020 & 2030 -
i.e. minus 50% (to avoid "uncontrollable ecosystem collapse" (Figueres),

[i] & completes to -100% by 2040 which (sadly) still adds
(albeit) declining amounts of CO2 to the global atmosphere.

Over the years the C&C approach generated a lot of support from inumerable persons
