Climate Change and Development Authority (CCDA) is a new government entity that is now undergoing transition from the former Office of Climate Change and Development (OCCD).

CCDA coordinates the Climate Change efforts of the Government of Papua New Guinea, a continuation of basically where the former OCCD left off. It is the coordinating entity for all climate change related policies and actions in the country. Additionally, it is the designated National Authority under the United Nations Framework Convention on Climate Change (UNFCCC). The office is currently undergoing a transitional phase which requires a major re-structure, in a coordinated and structured manner,complying with its own Climate Change Management Act (CCMA) 2015. The CCMA 2015 clearly defines this in Sections 8-11 of the Act on the organisation’s establishment, purpose, functions and powers.
