The Association of Children's Museums (ACM) is a global network dedicated to supporting and advocating for children's museums worldwide. It serves as a hub for sharing knowledge, resources, and best practices among its members, which include museums, educators, and professionals committed to enriching the lives of children through interactive and educational experiences.

ACM focuses on fostering environments where children can learn through play, creativity, and exploration. The organization provides a platform for collaboration and innovation, helping museums to enhance their educational offerings and community impact.

In terms of sustainability, the Association of Children's Museums encourages its members to adopt environmentally friendly practices and integrate sustainability into their operations and exhibits. However, specific details on ACM's own sustainability initiatives or certifications are limited. The organization promotes awareness and education on environmental issues through its network, aiming to inspire future generations to value and protect the planet.
