The university's CO2 footprint - a visual representation of Leiden University's environmental impact - is calculated every year. The CO2 footprint for 2020 shows a striking break in the trend in terms of energy use, mobility and waste.

The University's CO2 footprint has once again decreased. This is the conclusion of the 2022 Sustainability Report. The report also concludes that steps have been taken to integrate sustainability into Leiden University education and research.

Leiden University continued to reduce its carbon footprint in 2021 by being more careful with natural resources and making structural reductions to its energy consumption. This is what it says in the Sustainability Report 2021.

How much energy and greenhouse gas emissions can Dutch homes save? Xining Yang uses Leiden as an example and shows with his research how enormous the impact can be. At least, if we work harder on becoming more sustainable. Based on the models he developed, Yang will receive his doctorate on 28 June.

Four bachelor’s students in archaeology have embarked on a month-long field school in Aruba. They will work with Harold Kelly, a local archaeologist at the National archaeological museum of Aruba, and with the research team of Island(er)s at the Helm.

Hydrogen can help to solve the climate problem. At least, if we start producing it in the right, clean way. Leiden researchers mapped out the global environmental impact of hydrogen production and looked ahead to 2050. They published their work in Energy & Environmental Science.

During the summer, staff and students of the Faculty of Archaeology travel to all parts of the world, initiating or joining fieldwork projects. Read some of our students' stories here!

The University has established an Environmental Policy Plan, which sets a number of ambitious goals to reduce its direct environmental impact and CO2 footprint and to raise staff awareness of sustainable and eco-friendly operations.

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

He had been back from Australia for less than 48 hours, but there was no sign of that. Michel Mandjes of MI had the honor of kicking off the very first Tuesday Talks: Science Insights on Tuesday. He did so with a presentation on complex networks.

Education

With the start of June, the annual Leiden Archaeology Field School has begun. Like last year, the Field School takes place in Oss. Every week, a group of 25 first year students gets to learn the ins and outs of a professional excavation.

Arbitration law has grown into a ‘sexy’ area of practice about which students are keen to write a thesis and in which many lawyers specialise.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

The film MعLMIN made by Visual Ethnography alumna Loes Moree will be screened during the fourth Fieldrecordings event. Field Recordings is an annual event for visual anthropology, sound art and landscape film.

If European countries rely solely on technological advances, they won't be able to limit global heating to 1.5 degrees. Households will also need to change their lifestyles. This 'inconvenient truth' is the result of calculations done by industrial ecologist Stephanie Cap. ‘It's not a popular message,…

For the first time, a court has ordered a company to reduce its carbon dioxide emissions. Lawyers see it as a landmark ruling that will have far-reaching consequences for Shell and possibly also other similar companies.

Back in June, the annual Leiden Archaeology Field School took place in Oss. For a month, every week, a group of 25 first year students gets to learn the ins and outs of a professional excavation. This is what they have been prepared for in the past year. ‘It is very exciting to put all the theory into…

Innovation through repetition. That is how university lecturer Jurriaan Witteman describes his research on the automatic processing of angry voices in the brain. The original research was conducted 20 years ago, but, with an NWO grant, Witteman is now going to see if those results are accurate.

Human resources

Hans Slabbekoorn researches animal sounds and the effect of the noise we humans make on these animals. He is also committed to making his discipline more diverse.

After years of hard work, Urban Studies graduates were presented with their diplomas. How do they look back on their studies? And what can we expect from them in the future?

Understanding the proces of electrochemical reactions is essential to improve the technology for the energy transition. Fuel cell cars, for example use hydrogen produced from the electrolysis of water. Mariana Monteiro did fundamental research on the process and won two prizes with her thesis.

If your work allows it, you can work partly from home and partly at the University. How this combination of working from home and at the University will turn out for you depends on your own working activities and situation and those of your team. This means that tailor-made solutions are needed.

You can apply for an exemption from parking fees when you demonstrably disabled or when you have to park on different parking lots for your commute.

To set up your digital workspace, use the following tools: Webmail, Office 365 and OneDrive.

Imagine we could do what green plants can do: photosynthesis. Then we could satisfy our enormous energy needs with deep-green hydrogen and climate-neutral biodiesel. Scientists have been working on this for decades. Chemist Chengyu Liu will receive his doctorate on 8 June for yet another step that brings…
