International climate financing must increase to at least USD300 billion per year by 2035. Previously, 100 billion per year was considered a binding target. The industrialized countries in particular must provide these funds – from their budgets, via privately mobilized funds or multilateral development banks (MDBs). Developing countries can also contribute to this goal via their MDBs or through voluntary contributions. The industrialized countries and the EU in particular have thus achieved a fundamental goal for this COP: expanding the donor base.
