This guide provides straightforward actions for anyone interested in sustainable research practices to implement in their lab or research environment. It serves as a starting point to inspire you and your team to make research more environmentally friendly. Intended for anyone in the research community - whether working in a lab, studying, or managing research administration - each section is clearly labeled for easy navigation. While the Green Guide is designed to be broadly applicable across research fields, additional information can be found in our resources or by joining the LEAF program for further guidance on sustainable research practices. Please feel free to share this guide, created by CPR Goes Green, a grassroots initiative at the Center for Protein Research, University of Copenhagen, to promote sustainable practices broadly.
