UNEP’s funding is made up of a) Core Funding, comprised of the Environment Fund (EF), and the UN Regular Budget (RB), and b) Extra-Budgetary Funding (XB). Core funding is primarily used to fund staff posts, with a small amount allocated to funding project activities. Most funding for project activities comes from XB funding. Core funding makes up around 15% of UNEP’s funding, XB accounts for around 85%
