This report, part of the State of Climate Finance in Africa series, provides a deep dive analysis of tracked climate finance in Nigeria in 2019/2020. Following a discussion of climate change policies, strategies, and plans enacted in the country to date, it delves into climate finance committed to and within Nigeria, mapping flows along their lifecycles from sources and intermediaries (private and public), the financial instruments used to channel funds (grant, debt or equity), and through to how finance is ultimately used on the ground (mitigation, adaptation or dual benefits). While data gaps limit a fully comprehensive assessment, the key purpose of this case study is to inform and facilitate discussions among policymakers and public and private financiers, identifying gaps and opportunities for scaling climate finance in Nigeria.
