In line with the UN80 Initiative, launched in early 2025 to promote the urgent modernisation of the United Nations system, substantial budget cuts were announced. As a result, several UN entities have reduced their staff and are considering further adjustments, which may affect a wide range of global programmes, including those addressing environmental issues. These reductions could weaken the UN’s capacity to implement the 2030 Agenda. Unless urgent measures are taken, the environmental Sustainable Development Goals may not be achieved. This article provides a concise, descriptive overview of the situation and proposes alternatives for strengthening links between international and local environmental action in support of achieving the relevant Goals.
