Story

The Congress
Since 2014, the International Cradle to Cradle Congress #C2CC23 has been the first and to date the world’s largest platform for C2C solutions with approximately 1,000 visitors, 100 speakers and a 2-day program.
THE HOST
C2C NGO
Problems can only be solved when they are thoroughly understood – this is the aim of our educational initiatives. C2C NGO connects the fields of business, education, politics, and civil society. Our active volunteers, at work in all corners of the country, make Cradle to Cradle accessible to everyone.
Our Congress, with over 1,000 participants from the C2C community, is the largest C2C Platform worldwide. They come together annually to hear from key leaders in business, science, and politics. Fora, lectures, and workshops provide space for meaningful discussions and networking opportunities.
In 2019, we established the C2C LAB in Berlin: the world’s first comprehensive Cradle to Cradle certified renovation. Serving as an educational center, NGO head office, and living lab, it is here where the C2C school of thought and design concept become reality. All who are passionate about working towards creating a positive footprint are welcome to join us in our endeavor.
