The European Advertising Standards Alliance (EASA) is the single authoritative voice on advertising self-regulation issues and promotes high ethical standards in commercial communications by means of effective self-regulation, while being mindful of national differences of culture, legal and commercial practice. These standards are promoted for example via EASA's Advertising Self-Regulatory Charter and EASA's Best Practice Recommendations.

As a non-profit organisation based in Brussels, it brings together national advertising self-regulatory organisations (SROs) and organisations representing the advertising industry in Europe and beyond.
