IDA is committed to financial transparency. We know our members and supporters want to make the biggest difference possible, so we diligently work to ensure your hard-earned money is put to work addressing the big issues. Your dollars translate into increased protections of the night sky, ecosystems, wildlife, and the planet.

IDA thanks our members, supporters, Brand Partners, and foundations for their generous support. We couldn’t protect the night skies without you!
