The My Green Lab program has been instrumental in the department's sustainability efforts. It focuses on saving energy in lab equipment, improving waste management, and using eco-friendly materials. These measures significantly reduce the environmental footprint of the department’s research.

The certification process for My Green Lab includes an initial assessment, implementing recommended changes, and a final review to measure progress. Labs can earn different certification levels -bronze, silver, gold, platinum, or green- based on their adoption of sustainable practices.

Pilot project

In January 2024, the Contaminant Chemistry Unit at the department began the certification process with a detailed survey covering procurement, waste handling, solvent use, fieldwork, electricity, and water use. The initial results showed an average score of 50%, qualifying for a silver certification. The survey highlighted strengths in resource management, fume hoods, fieldwork, and travel, while also identifying areas needing improvement, such as purchasing, green chemistry, cold storage, and energy use. The unit has six to eight months to make improvements before a final survey and certification, which will be valid for two years.

Merle Plassmann, Staff Scientist at the Contaminant Chemistry Unit and the driving force behind this project, emphasizes the importance of educating lab staff about sustainable practices and their relevance. "This includes routine checks like gas line inspections and fume hood maintenance, as well as applying green chemistry principles in daily tasks," she explains. "We've also adjusted -80°C freezers to -70°C, saving 20-30% in electricity, and are consolidating -20°C freezers to reduce energy use. Additionally, Stockholm Univesity is working on a long-term project to create a 'marketplace' for sharing surplus lab equipment to cut down on procurement needs."

The benefits of certification

Inspired by an article in the journal Nature and supported by positive feedback from the university’s environmental group and internal stakeholders, the program began as a pilot with one unit. If successful, it will extend to other units within the department.

"Certification brings many benefits," explains Plassmann. "It raises awareness about sustainability, encourages collaboration among departments, inspires innovative research practices, and saves money. Public recognition of certification also enhances the department’s reputation, which is helpful for grant proposals and can set an example for other labs."

The recent external audit, conducted from May 20 to May 22 praised the department’s integration of the university's Climate Roadmap, which aims for carbon neutrality by 2040 and alignment with the UN’s Sustainable Development Goals (Agenda 2030). The audit highlighted the department’s high levels of engagement, transparency, and awareness among staff and students. It also commended the department’s events, like the Environmental Research Day, which promote collaboration and improve the department's overall environmental management. Minor suggestions included better reporting of environmental issues and improving communication strategies.

Looking ahead to the next audit in May 2025, the Environmental Science Department remains dedicated to leading in environmental sustainability, building on a strong foundation, and continually improving.
