Policy impacts from new research exploring the issue of light pollution and how reducing it can help to address major societal challenges are discussed in this latest episode of the CIHT Podcast, featuring Dr Christopher Kyba of the German Research Centre for Geosciences.

In conversation Dr Kyba explains the research which involved measuring from satellites the contribution of street lighting to night time light emissions from urban areas.

The findings indicate that most wasted artificial light does not come from street lights but from other sources.
