 The General Conference

Considering that enhanced global awareness of, and increased education in, the science and technologies of light is vital in order to address challenges in areas such as sustainable development, energy, and community health, and for improving the quality of life in all countries, but being aware also of the adverse impacts of light pollution on nature and human lives,

Stressing that the applications of light science and technology are vital for advances in medicine, communications, entertainment and culture,  and  that  light-based  technologies  respond  to  the  needs  of  humankind  by  providing  access  to  information  and  increasing  societal  well-being, as  well  as  promoting  peace  through  improved communications,

Noting the broad and significant impact of recent initiatives of UNESCO’s International Basic Sciences Programme and the  enthusiastic  commitment  by  the  International  Year  of  Light  and  Light-based  Technologies  consortium to continue working with UNESCO in the framework of internationally-coordinated outreach and education programmes,

Recognizing that it  is  essential  to  ensure  that  existing  gains  from  previous  UNESCO initiatives  in  science  and  education are effectively followed-up and strengthened,

Also recognizing the importance of light and light-based technologies,

1. Decides to proclaim 16 May of each year as International Day of Light;
2. Invites the Director-General to:

(a)   promote the celebration of International Day of Light;

(b)   encourage Member States, intergovernmental and non-governmental organizations, universities, research centres, civil society associations, schools and other local stakeholders to actively participate in the event in a manner which each considers most appropriate and without financial implications for the regular budget of UNESCO
