Green Lab is an international non-profit organization based in the USA that certifies laboratories for sustainable working practices. My Green Lab was named by the United Nations in its "Race to Zero" campaign as one of the key players in the goal of making medical and pharmaceutical companies, laboratories and research facilities climate-neutral by 2050. Laboratories are among the most resource-intensive workspaces in the field of biomedical research, and facilities at Cologne University Medicine have already been certified or are in the process of certification.
