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 agreement was signed between the Brussels Capital Region of Belgium GCF, and the World Bank in December 2014, for contributions made at the Initial Resource Mobilisation (IRM) period. Amendments were made to the agreement in December 2015 and December 2016.
