The event was organised by the Sky and WWF in the premises of the European Parliament in Brussels with…

Last week Esther Kentin participated in the Second Meeting of the Ad Hoc Open-Ended Expert Group on Marine Litter and Microplastics organized by UN Environment in Geneva.

Microplastics are everywhere: in the ocean, in cooking salt and even in animals. Should that worry us? 'Yes,' said environmental scientist Thijs Bosker during a pop-up lecture in The Hague on 8 September. ‘We really need to do something now, not wait until it becomes an even bigger problem.’

Some thirty Leiden students balanced on SUP boards for the Supping for Sustainability Lustrum activity. Together with alumnus Merijn Tinga, better known as the Plastic Soup Surfer, they paddled their boards through the Leiden canals and waterways, fishing plastic waste out of the water.

Merijn Tinga hit the headlines in 2016 as the Plastic Soup Surfer. In force six winds, the Leiden biologist ventured across the English Channel on a hydrofoil kiteboard made from plastic bottles. Interview with this Leiden artist who is fighting the mountain of plastic waste and finding his feet as…

Last July, after the end of my Advanced LLM in Public International Law, I wanted to find new tasks to prove myself on topics related to what I studied during my stimulating master in the Netherlands. In the impossibility to work “on the field” as I was busy for my bar exam in my own country and I was…

The number of international organisations has increased over the last decades. As has the number of cities interested in housing these organisations. International organisations bring wealth to cities and help improve their reputation. They often act as a magnet for other international corporations.…

An international team of astronomers including Leiden scientists publishes the image of a young star with a surrounding dust disk that is still being fed from its surroundings. The phenomenon around the star SU Aur may explain why so many exoplanets are not neatly aligned with their star. The European…

Leiden University is committed to reducing our water consumption.

What is my contribution to the world? This is what students and researchers at Leiden University College The Hague (LUC) ask themselves every day. They want to make a difference with their teaching and research in the four global challenges of ‘Peace and Justice,’ ‘Sustainability,’ ‘Diversity’ and ‘…

While colloidal aggregates are often undesirable due to their random shapes, we exploit them as a starting point to synthesize patchy particles.

Leiden University offers its students a wide range of bachelor's, master's and minors that explore sustainability or climate. Here, you find an overview of those programmes in the academic year 2020-2021.

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

How can an effective ‘Safe and Circular by Design’ method be developed for practical application in a designer’s context, particularly for the initial stages of product design, incorporating Safe-by-design strategies, LCA/LCT, risk assessment and ethics?

On 11 March, pharmaceutical company Janssen received approval to launch its corona vaccine on the European market. This made Janssen the fourth company to be given the green light by the European Medicines Agency. As Lead of the Janssen Campus in the Netherlands, Biology alumnus Bart van Zijll Langhout…

‘Fighting for health’ is the title of Professor of General Practice Hedwig Vos’s inaugural lecture – and for good reason. Public interest is at the heart of everything she does, from advancing knowledge about women’s health to reducing health inequalities.

Last week Esther Kentin participated in the Second Meeting of the Ad Hoc Open-Ended Expert Group on Marine Litter and Microplastics organized by UN Environment in Geneva.

How do you count the nanoplastics in your body? Leiden researchers published a method in Nature Protocols today that should make this easier. Important for both environmental and medicine research.

Time and again synthesised substances have been shown to pollute the environment more than lab tests predicted. In her inaugural lecture on 16 November, professor of Ecotoxicology Martina Vijver gives a warning for the risks of new, man-made chemical substances and nanomaterials. Various media payed…

A Leiden Groningen student team has reached the European finals of the BISC-E competition. In this annual competition students have to come up with a sustainable solution to a major social problem. The team invented Suckerspheres: a natural alternative to the plastic microbeads that are still widely…

Op de dag van de duurzaamheid van 10 oktober startte de 'Billiecup' pre-pilot op de Faculteit der Rechtsgeleerdheid.

Canal Cups, Auke-Florian Hiemstra and Liselotte Rambonnet’s project to rid Leiden of disposable plastic cups and its canals of litter, has taken 59th place in Trouw newspaper’s Top 100 sustainable initiatives.

Having lectures on sustainability when you're a first-year student of Law, or a course on climate change when you're studying Public Administration may sound odd, but that is just what Associate Professor in Environmental Sciences Thijs Bosker wants to see happening. Together with his colleague Paul…

You can't see them with the naked eye, but they are highly likely to pose a threat to our health: microplastics. These tiny plastic particles are present everywhere in the environment, including within our bodies. On science platform The Conversation molecular biologist Meiru Wang offers valuable insights…

An Interdisciplinary project group of the Master Industrial Ecology was awarded a prize for its project “From waste to resource, One chain with shared responsibility”, commissioned by AEB Amsterdam and Waag Society.

The project

In September 2023, we started transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.

Flying is cheaper than driving a car, but a disaster for the environment. Yet few politicians dare to levy excise duty on kerosene. This is only one example from a world where emotions and yelling are burying facts, and in which scientists lose connection with society.

Life returned to something resembling normal after Covid but other crises soon took its place. These great challenges are also being felt at the University and our researchers are working on solutions. The nitrogen crisis, problems with young people’s services and an increasingly urgent climate crisis:…

Earth Overshoot Day, the day on which humanity has used all the natural resources that the Earth can regenerate in a single year, falls on 30 July this year. Three researchers from Leiden explain how this date can be pushed back.

PhD defence
