Contraction-&-Concentrations

As future greenhouse-gas emission contract, their concentration in the atmosphere slows and stabilises. Contraction - premeditated at an effective rate - fulfils the objective and the principle of precaution in the UN Climate Treaty. Faster contraction means less dangerous rates of climate change.

  • "Contraction & Convergence" or "C&C" establishes a constitutional, global-equal-rights-based framework for the arrest of greenhouse gas emissions

Contraction-&-Convergence

As Contraction occurs, a North [Red] South [Black] Convergence of international 'shares' occurs. Accelerating convergence to equal shares per head, relative to the global rate of contraction, observes the principle of equity in the UN  Treaty. This is the constitutional way of solving the climate's opportunity-cost to developing countries while sharing future constraint at rates that avoid dangerous climate change.

Contraction-&-Conversion

As Contraction & Convergence occurs, a global Conversion to emissions-free energy systems can be financed by the international trading of emissions permits created by C&C, thus levelling the global playing field. Making effciency a function of equity is constitutional. This inclusivity observes the principle of 'sustainable development' for all in the UN Treaty.

Expansion-Divergence-Damages

Should Contraction & Convergence and Conversion fail to occur, the globally asymmetric growth of emissions and income will continue, triggering rates of damages that will collapse security and overwhelm the economy.

The need to avoid this is obvious and absolute.
