The next UN Conference on Climate Change, COP 21, will open in Paris on 30 November 2015. A lot is expected of this Conference as it is the decisive moment to renew the Kyoto Protocol providing the international community with an effective mechanism to deal with greenhouse emissions at a global level. Although expectations are very high, there is a growing scepticism on the ability of the Conference to deliver. Since Copenhagen, the UNCCC has not shown the capacity to reach concrete and effective agreements. This time the urgency to renew the Kyoto Protocol can exert a positive influence in order to achieve ambitious results.
