Development finance statistics

Environment: OECD DAC External Development Finance Statistics


The OECD DAC measures and monitors development finance targeting the environment using the environment marker. Introduced in 1992, this predates the Rio markers. Reporting on ODA flows has been mandatory since 1998. Reporting on non-credit OOF flows was introduced in 2010 on a voluntary basis.
