OPT recommends: -

"That the principle of “contraction and convergence” (rich and poor converging towards a common per person emissions target) be accepted as an equitable starting point for distributing total tolerable carbon emissions, provided that this is allocated to states on the basis of their population size at a specific date.

This would encourage the adoption of population restraint policies; whereas allocation on a simple per person criterion would encourage continued population growth, thus continuously reducing every person’s carbon entitlement."

The Optimum Population Trust on C&C

"Contraction and Convergence is a prime example of a UNFCCC-compliant Global Climate Change Framework. It is a rational formulation for reconciliation of 'Climate Justice without Vengeance'.

Several ideas derived from C&C have surfaced since Kyoto with ideas that can be perhaps in various ways incorporated into C&C.

However, there is an overwhelming need for an over-arching UNFCCC-compliant Framework that enables the globally competing interests of the over-consuming and the under-consuming to be reconciled with each other and with the objective of the UNFCCC in a non-random manner.

We feel that C&C is the veteran and indeed the apex example of this and urge you to consider our request.

At Kyoto in December 1997 and shortly before they withdrew from these negotiations, the USA stated, “C&C contains elements for the next agreement that we may ultimately all seek to engage in.”

The adversarial reasons for their withdrawal then were in play again at COP-15. C&C answers this in a unifying and constitutional way and the need for this answer becomes increasingly critical."
