Environmental Education and Training (EET) promotes attitudes and value systems that influence environmentally ethical behaviour by developing understanding, skills and values that will enable people participate as active and informed citizens in the development of an ecologically sustainable and socially just society  

Environmental Education is fundamental to the achievement of the goal of sustainable development. Education, awareness raising and training are essential to UNEP fulfilling its mandate of Inspiring, Informing and Enabling nations and peoples to achieve sustainable development.

The Environmental Education and Training (EET) activities of the United Nations Environment Programme are founded on its mission of inspiring, Informing and Enabling nations and peoples to improve their quality of life without compromising that of future generations. This is done to promote innovative, action oriented, and value-based education for sustainable development by ensuring that environmental considerations are taken into account.   

The Environmental Education and Training Unit is responsible for the implementation of Environmental Education and Training activities in close collaboration with all UNEP Divisions.  The Unit is located in the Cross-Cutting Issues Branch in the Division of Environmental Policy Implementation (DEPI) at UNEP Headquarters in   Nairobi ,  Kenya  .  There are also EET regional focal points located in Mexico City (for Latin America and the Caribbean region), Bangkok, Thailand (for Asia and the Pacific region), Nairobi (Africa), Geneva (Europe), Bahrain (West Asia region).

The Environmental Education and training Unit in UNEP undertakes this crucial function by developing and strengthening environmental education and training initiatives to address all institutions, governments, segments, and ages in society.

 The Unit also collaborates with other partners, which include Governments, regional and national environmental education and training centres, institutions of higher learning, international and local non-governmental organisations and the private sector.
