Nigeria is an energy insecure country and heavily relies on combustion of fossil fuels to provide power to meet its teeming population’s energy needs. The Nigerian government desires transitioning to a low carbon economy and securing access to clean power for its energy needs. However, Nigeria is not capable of independently financing its transition to a low carbon economy and would require aid to achieve this objective. Nevertheless, Nigeria has been overlooked by international actors capable of donating financial aid for climate action or collaborating with it on sustainable projects for a myriad of legal and non-legal considerations. The situation in Nigeria calls for urgent international intervention as modern science has linked the evident effects of climate change to carbon emissions from the combustion of fossil fuels. This thesis employs a doctrinal approach to identify the Market-Based and Non-Market approaches within the Paris Agreement as legal avenues Nigeria can explore to secure needed financial aid and support on climate action. These legal avenues also incorporate vital accountability measures to reassure international actors that the Nigerian government will undertake all necessary action to champion its long-awaited transition to a low carbon society. This thesis discusses practical ways the Market-Based and Non-Market approaches of the Paris Agreement ought to be implemented in Nigeria, within the legal ambits of Nigeria’s climate system and with due acknowledgement of its domestic realities. Furthermore, this thesis proffers recommendations regarding ideal regulatory overhauls the Nigerian government ought to implement to attract international financial aid and support on climate action.
