Members of the CTA agree to our shared principles and values and are invited to use the CTA Seal on their websites and in their communications to demonstrate their commitment to the CTA and to encourage dissemination of the CTA concept. Adopting the seal is an explicit pledge towards increasing interoperability between our technologies and our communities.
