International Year of Light
2015 United Nations observance to raise awareness of light science and its applications

The International Year of Light and Light-based Technologies 2015 or International Year of Light 2015 (IYL 2015) was a United Nations observance that aimed to raise awareness of the achievements of light science and its applications, and its importance to humankind. IYL 2015 opening ceremonies was held on 19–20 January 2015 in Paris.
History
The International Year of Light is "a global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health."
UNESCO delegates from Ghana and Mexico introduced the proposal to the executive board, explaining the motivation and mission underlying the International Year of Light. The resolution was adopted by the executive board joined by co-signatories from a further 28 Board Members. The resolution proposing an IYL 2015 was placed before the 190th Session of the UNESCO executive board held in Paris from 13–18 October 2012 by Ghana, Mexico, and the Russian Federation (Board Members) and New Zealand (UNESCO Member State).
The resolution A/RES/68/221 proclaiming the IYL 2015 was adopted on 20 December 2013 during a plenary meeting of the 68th Session of the UN General Assembly, with the General Assembly acting on the recommendation of its Second Committee (Economic and Financial) during consideration of an Agenda item on Science and Technology for Development.
Prince Andrew, Duke of York is a patron of IYL 2015.

Why this record matters
“International Year of Light” is worth following because a concise public description often conceals a longer documentary argument. Here, International, Year and Light provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 8, 2026. The linked authority identifier is Q15646474. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2015, 2012 and 2013.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
