Abstract: Climate governance in Nigeria is a new entrant to the domain of public interest. Attempts at legislation through agenda setting inroads and eventual attaining the list of state responsibilities for public policy has been an illusion. This study attempts an interrogation of the political architecture-National Legislative Assembly (NASS) and Federal Executive arms of government in Nigeria capacity to marshal articulate climate change policies and sustain its governance in the midst of competing exigencies. Relying on secondary documents, the “public choice theory” was selected to understand the legislative delays and its ramification for Nigeria. The core argument herein, hinges on the comatose state of the Nigeria’s earlier vision 2020 framework in which climate change was encased and the obscurity of the vision. This study further posits the need for governance urgency connected to concretized deliverables within the context of the “greater good” window shut consistently against vulnerable groups.
