UNITED Nations Secretary-General Ban Ki-moon has invited all world leaders to a signing ceremony on April 22 for the historic climate agreement that was reached in Paris in December last year.

The signing event will take place at UN Headquarters in New York on the first day the agreement will be open for signature, which coincides with the observance of International Mother Earth Day, observed in many countries as simply Earth Day.
 
The Secretary-General intends to use the occasion of the signing ceremony to further engage leaders from business and civil society to put the new agreement into action.
 
In his invitation letter, the Secretary-General said that leaders’ participation could also facilitate the early entry into force of the Paris Agreement and “provide for the smooth finalization of the operational details needed to give effect to the provisions of the new Agreement.”
