On Thursday, the UN secretary general, Ban Ki-moon, attempted to rage expectations for the ongoing climate talks outside of Paris. He recommended negotiators to not make the perfect an enemy of the good.

On a brief stop at headquarters prior to returning to France, he told reporters, “There is no perfect agreement. But our goal is clear: an agreement that truly addresses climate change, and puts the world on track for long-term prosperity, stability and peace. That is what the days ahead in Paris can and must deliver”.

During most of his tenure, Mr. Ban has tried to push for a climate agreement. He will soon start his final year as secretary general. Securing a pact in France has been seen by many as vital to his legacy.

On Thursday, while answering a question asked by a reporter, he clarified that commitments made by nations worldwide, would be mainly voluntary, not binding legally. He said that diplomats were still attempting to find ways to ensure that these promises would be carried out.

He said, “I understand that member states are discussing many different ways how to make this agreement very robust and meaningful and a universal one with an implementable framework”.

Mr. Ban pushed both rich and poor nations to play their part. He added that he was continuously pressing developed countries to make them identify their responsibility to take the lead, while has urged developing countries to put in more efforts, with their increasing capabilities.
