 Welcome to ALAN 2023 from the Conference Chairs!

On behalf of the Steering and Local Organising Committees, we are pleased to invite you to attend the 2023 Artificial Light at Night Conference.

The ALAN conference series is dedicated to examining all aspects of artificial light at night, including how light is produced (e.g. technologies, industry, and lighting design), where it is present (e.g. remote sensing), the effects it has on humans and nature (e.g. ecology), how it is perceived (and not perceived) by the public (e.g. perceptions of safety and security), and how the benefits and detriments of lighting may be balanced by regulation (e.g. standards and laws).

As population grows and technology evolves, the use of artificial light at night continues to increase, intensifying the impact on human and natural environments. So as scientists, practitioners, regulators, and users of artificial light at night, the need to understand, innovate, and educate has never been stronger. ALAN 2023 will bring us together, linking inquisitive minds and new ideas.

We look forward to sharing, learning, and connecting with you August 10 – 13, in Calgary, Canada during
ALAN 2023.
