Acting on the nomination of Secretary-General Kofi Annan, the United Nations General Assembly in 2006 unanimously elected Steiner Executive Director of the United Nations Environment Programme (UNEP) for a four-year term. At the time, he was not nominated by a Member State, but prevailed over candidates such as Børge Brende of Norway and Rajendra K. Pachauri of India. His mandate was later extended twice, this time on the proposal of the Secretary-General Ban Ki-moon.

In November 2018, Guterres also appointed Steiner to co-chair (alongside Maria Ramos) the United Nations' Task Force on Digital Financing of Sustainable Development Goals.
