Speaker: Joint IDA / SDAA meeting

Topic: The International Dark-Sky Association (IDA) 

The International Dark-Sky Association (IDA) is the recognized authority on light pollution and is the leading organization combating light pollution worldwide. Carefully crafted and robust public policy is crucial to fulfilling IDA’s mission to protect the nighttime environment and our heritage of dark skies. IDA is involved in a variety of efforts to influence the decisions of various lawmaking and oversight bodies worldwide to formulate, adopt, implement, evaluate or change public policies on outdoor lighting. We partner with various government entities to support policy priorities that protect night skies and promote quality outdoor lighting.
