Negotiators at the Paris climate summit aim to finalise a global agreement to tackle climate change this Saturday after talks overran, hosts France said.
According to the French Foreign Minister Laurent Fabius things are moving in the right direction and a decision will be made on Saturday. One current obstacle is determining the compensation for countries most affected by climate change.
The draft document highlights that temeratures must be kept well below the 2C and every effort must be made to limit the temperatures increases to 1.5C.
The main outstanding issues seem to relate to the question of differentiation between developed and developing nations. Richer nations want emerging countries to take on more responsibility with cutting emissions and provide finance to the very poor nations affected by rising temperatures.
Richer nations have also insisted on developing a single system of verification of promise for all countries ensuring a fair, transparent deal for every nation.
