Three sources of income support of the implementation of the Programme of Work directly: 1) the UN Regular Budget, including the UN Development Account, which supports the core functions of the Secretariat including servicing of the Governing Bodies, 2) the Environment Fund, which is the foundation that enables UN Environment to implement its global and regional work across all areas of the programme and address emerging issues, and 3) Earmarked Contributions, which complement the core funding in the delivery of the programme. The Global Environment Facility (GEF) is the largest financial partner of UN Environment that funds activities aligned with the Programme of Work.
In 2016, UN Environment received $464.9 million for 2016 and future years against the annual budget of $338.8 million. The UN Regular Budget and the Environment Fund together form the core of the organisation’s funding and amounted to 28% of the total funding available in 2016. The Environment Fund received just under 50% of the approved budget of $ 135.5 million from 86 out of the 193 Member States. The earmarked contributions in direct support to programme amounted to $138.7 million or 45% of the funds available. This is higher than the projected budget of $101 million. The Global Environment Facility provided $238.5 million in revenue through letters of commitment for 2016 and future years. Out of this, $84 million was available for project implementation, or 27% of the total funding available in 2016.
