What is the impact of nuclear energy exclusion on MDB financing?

Question

Accepted Answer

Excluding nuclear energy from ESG frameworks blocked nuclear projects from MDB development financing and reduced bank appetite for the sector
ESG frameworks traditionally excluded nuclear energy, which in turn prevented the nuclear sector from accessing development financing from major Multilateral Development Banks (MDBs). This exclusion also discouraged financial institutions from financing nuclear projects and nuclear companies, including in the period when the World Bank and Asian Development Banks had not yet included nuclear energy in their financing frameworks. The World Bank was stated as excluding nuclear energy until June 10, 2025, while Asian Development Banks were stated as excluding it until November 24, 2025.
What MDBs and development financing channels did nuclear energy miss
The exclusion meant the nuclear sector could not access development financing from MDBs including the World Bank and regional MDBs such as the Asian Development Banks during the stated exclusion windows. Those financing channels are explicitly described as being precluded by the ESG frameworks’ traditional approach to nuclear energy. As a result, nuclear projects were left outside the development-financing pathways tied to those ESG-aligned MDB frameworks.
How the exclusion affected broader financial institutions beyond MDBs
The impact was not limited to MDBs: the exclusion also discouraged financial institutions from financing nuclear projects and nuclear companies. In practical terms, this meant fewer lenders were willing to fund nuclear assets when their sustainability and ESG criteria did not recognise nuclear energy within the financing framework. This environment contributed to nuclear energy being “shunned by a number of investors and banks” for decades, as described in the same coverage.
The specific timing of when inclusion began for MDB frameworks
The World Bank inclusion timing is given as “until June 10, 2025,” and Asian Development Banks’ inclusion timing is given as “until November 24, 2025.” Those dates frame the period in which nuclear energy remained excluded from the ESG-linked MDB financing position, and they mark the point after which the sector could begin to be considered within those MDB-aligned frameworks. The coverage links this change in recognition to a broader shift in sustainable finance practices.
How later financing examples show what changed after ESG/MDB recognition
After the period of exclusion, nuclear financing started appearing in sustainable instruments such as green loans and green bonds, including a “world’s first” green loan in November 2022. Crédit Agricole CIB signed a green loan entirely dedicated to France’s nuclear sector for a €1 billion bilateral loan to EDF to fund maintenance of existing French nuclear power plants, made possible by EDF’s updated Green Financing Framework incorporating nuclear power following the European Union’s green taxonomy. The later emergence of nuclear-related green loan facilities and bank participation in nuclear financing events is presented as part of the shift away from earlier ESG exclusion barriers.
