International Day of Light 2021

The International Day of Light is a global initiative that provides an annual focal point for the continued appreciation of light and the role it plays in science, culture and art, education, and sustainable development, and in fields as diverse as medicine, communications, and energy. The broad theme of light will allow many different sectors of society worldwide to participate in activities that demonstrates how science, technology, art and culture can help achieve the goals of UNESCO - education, equality, and peace.

Society at large is experiencing a variety of challenges impacting its trust in science. The last 12+ months have openly demonstrated the importance of evidence-based solutions — in fields from healthcare to engineering.

Celebrated on 16 May, the International Day of Light is an annual United Nations observance raising global awareness of the importance of light science and technology in areas such as communications, sustainable development, climate action and healthcare.

The message of this year's International Day of Light - Trust Science - encourages both scientists and the public alike to sign and support a declaration affirming their trust in science and the importance of public confidence in the scientific process. Now is the time for us all to pledge our support.

We ask all supporters of the International Day of Light and its objectives to join with us in signing the Trust Science Pledge. This includes those who support the crucial role of the scientific process in improving our quality of life.
