The Max Planck Sustainability is a grass-roots initiative within the Max Planck Society. It was founded in 2019 in Magdeburg during the first sustainability workshop. The members of the network are committed to improving cooperation of research and administration in the Max Planck Society to create an exemplary and sustainable scientific environment. Our long-term vision is to contribute to an environmentally-friendly Max Planck Society through less resource-intensive scientific and day-to-day practice. We also encourage communication among local initiatives and other institutional entities of the Max Planck Society. The Max Planck Sustainability Network counts several hundred members - scientists, as well as technical and administrative personnel - from over 60 different Max Planck Institutes.
