University of Groningen frontrunner in green labs movement

29 May 2024

Scientists are essential to society and contribute to addressing major challenges such as the climate crisis. Although scientific research often leads to important breakthroughs and insights, laboratory research also involves unintended negative environmental impact, such as high energy consumption, the production of hazardous waste, and the use of resources.

Advocating for systemic change

In the Royal Society of Chemistry Sustainability Journal, Nobel prize winner Ben Feringa and his colleagues share a perspective article with a comprehensive literature review and a case study at the University of Groningen over the past years. The article was written with the intention to enhance lab sustainability and offer advice for other researchers worldwide looking to do the same. The publication advocates for leadership and systemic change in laboratory practices and research approaches.

Small steps, big impact

Feringa and his colleagues demonstrate that small steps can lead to significant improvements. By implementing simple measures like temperature settings, closing fume hoods, sharing chemical supplies, and developing standard operating procedures, many labs have already succeeded in reducing their emissions and waste streams. Additionally, they are undertaking larger projects such as using gloves made from recycled materials, washing pipette tips, and reusing solvents. Another strategy involves rethinking the organization of research projects to prevent waste from the outset and re-evaluating chemical reactions that were considered acceptable 20 years ago, but could now be performed more sustainably. Combining these kinds of measures can have a big impact, as is shown in the UG case study which resulted in annual savings of €398,763 and the equivalent of 477.1 tons of CO2.

LEAF programme

Green Labs UG, chaired by Gael Schaeffer, has gathered extensive data on the consumption patterns of wet and dry labs over recent years. Their approach includes utilizing LEAF, a software system that calculates lab emissions and identifies potential areas for improvement. Labs can join the LEAF initiative by contacting the LEAF coordinator Thomas Freese (

Guidebook for sustainable labs

A comprehensive guidebook with practical suggestions for lab users and lab managers was published internally in 2023. This guidebook shows, for example, what type of sustainable chemicals to use, where it is better to replace plastic with glass, what to do with old or damaged lab equipment and what to do with old lab coats. Since early 2024, this guidebook can also be found online and is already frequently used by the UMCG, Utrecht University, Wageningen University, University of Amsterdam and Washington State University for making their laboratories more sustainable.

Setting the example

The more labs join the network, the better, because as the researchers state in their paper: ‘We hope that we can initiate systemic change, so that we as researchers can set an example for the rest of society’.
