Climate scientists have proposed a contraction and convergence approach in order to share out the impacts of climate change in a more equitable manner on a global scale. This approach adopts the following principles: -

  • The precautionary principle
  • The polluter-pays principle
  • The equity principle

A drastic shift in global emissions of carbon dioxide from the burning of fossil fuels would be required to bring about stabilisation of CO2 levels to 450 parts per million. This is called the contraction principle. But how are these reductions to be shared out? Using the above principles, the fairest way is to set the limit by allowing an equal share of CO2 per capita, reaching this (convergence) by 2030. Having given allocations to each nation based on population size, trading would be allowed, so that technical and economic resources would be given in exchange for greater pollution ‘debt'. While this might seem idealistic at first sight, it is well within the economic sights of richer nations to reach such a target. The estimated reduction in carbon dioxide emissions required to stabilise the climate exceeds that of the Kyoto Protocol. In the UK a reduction in carbon dioxide emission by 60 per cent from current levels might seem overly optimistic. However, the actual cost of making such a change would amount to 0.02 per cent, or six months economic growth over a half century to 2050. The economic case for action has been robustly defended by the Stern Report, published in 2007.
