After two weeks of intense negotiations at Katowice in Poland ministers of  200 nations finally reached consensus on rules to implement the 2015 Paris climate agreement.

The Paris accord aims to limit rise in global atmospheric temperature to well below 2 degrees Celsius from pre-industrial revolution levels. UN Secretary-General Antonio Guterres hailed the development.

The concerns of developing nations including India and least developed nations on funding for carbon credit were finally addressed.

The affluent nations which are the main polluters agreed to pay for greening in the underdeveloped world.

The UN Secretary-General, however, qualified his praise for the negotiating nations saying that the approval of the Paris agreement work programme is the basis for a transformative process as this will require strengthened ambition from the international community.
