In May 2021, the United Nations General Assembly adopted a resolution to bring the global environmental community together in Stockholm, Sweden for a major international environmental meeting on June 2 and 3 2022, the week of World Environment Day.

“Stockholm+50: a healthy planet for the prosperity of all – our responsibility, our opportunity” (Stockholm+50) took place five decades after the 1972 United Nations Conference on the Human Environment. The event provided leaders with an opportunity to draw on 50 years of multilateral environmental action to achieve the bold and urgent action needed to secure a better future on a healthy planet.

By recognizing the importance of multilateralism in tackling the Earth’s triple planetary crisis – climate, nature, and pollution – the event sought to act as a springboard to accelerate the implementation of the UN Decade of Action to deliver the Sustainable Development Goals, including the 2030 Agenda, Paris Agreement on climate change, the post-2020 global Biodiversity Framework, and encourage the adoption of green post-COVID-19 recovery plans.

The meeting also reinforced the messages and the outcomes of the event to commemorate UNEP’s 50th anniversary (UNEP@50), which took place in March 2022, in Nairobi. Stockholm+50 was convened by the United Nations and hosted by the Government of Sweden with support from the Government of Kenya.
