Contraction and Convergence
"A brilliant, imaginative and simple means of reaching a just global
agreement on emission reductions has been put forward. Known as contraction and
convergence (C&C), it was first proposed by the Global Commons Institute (GCI) in 1990. Recognition of its unique qualities
as a framework for combating climate change has grown at an astonishing rate
since that date. C&C is founded on two fundamental principles: first, that
global emission of carbon dioxide must be progressively reduced; and second,
that global governance must be based on justice and fairness. ..." (from How We Can Save the Planet by Mayer
Hillman, p 119).
C&C consists of:
- Contraction: Global CO2 emissions are reduced towards an
internationally-agreed target by an internationally-agreed year.
- Convergence: Global convergence to equal per capita shares of this
contraction is phased towards the contraction target by an agreed year.
