Contributions to GCF are facilitated through Contribution Agreements or Arrangements signed by contributors, GCF, and the Trustee, which is the existing mechanism for receiving contributions to the Trust Fund.

This arrangement was signed between Ireland, GCF, and the World Bank in December 2016, for contributions made at the Initial Resource Mobilisation (IRM) period. Amendments were made to the arrangement in December 2017, December 2018 and December 2019.
