Which of the following agencies launched the 'International Environmental Education Programme'?

UNESCO launched the International Environmental Education Programme in the mid nineteen seventies to spread environmental learning.

The UN Environment Programme coordinates global environmental policy but did not head this education programme alone.

The World Conservation Union works mainly on species and habitat conservation, not on this schooling initiative.

The Global Environment Facility funds environmental projects and was set up much later.

The programme grew out of the Belgrade Charter and the Tbilisi environmental education conference.

Its aim was to build awareness, knowledge and skills for protecting the environment worldwide.
