What is the relationship between humans and nature like? And how can we use it to tackle climate problems? In the Master Honours Class ‘Planet in Peril’, students approach climate issues from the perspective of the humanities. ‘Things are not always as one-sided as they seem.’

Steel production is likely to take up a large portion of our future carbon budget. Capturing CO₂ from coal-based production won’t solve the problem. Technologies that rely on renewables are more effective, but not enough to get to net zero.

Greenhouse gas emissions related to pharmaceutical consumption increased by 77 percent over the past 24 years, according to a Leiden University study published in The Lancet Planetary Health. Moreover, efficiency gains have stalled since 2008. ‘Our best option is reducing consumption and minimising…

A staggering 6.5 billion chicks are killed worldwide every year. These are generally male chicks that are of no economic value. In Ovo has developed technology that can quickly determine the sex of a chick, to ensure that only female chicks are hatched. The first 150,000 chicks have now hatched in this…

Physicist Remko Fermin from Leiden University was awarded a Rubicon grant from NWO. He will use it to study superconducting diodes that could contribute to reducing the CO2 emission of data centres.

You should start working now, and the positive results will only be seen long after your term has expired. That is just about the worst thing you can say to politicians and policymakers.
