To this end, we address urgent challenges in relation to the mechanisms involved…

In the absence of stringent and coordinated international action, States might seek alternatives to promote environmental protection unilaterally.

Leiden University is aware of its role in society and wants to create a green, healthy and inclusive campus and have a positive impact on the field of climate and circularity.

What performance criteria does a new technology have to fulfill in order to be added to the list of future energy options and what constraints exist in terms of broad market penetration?

The project’s overall goal is to improve Indonesia’s environmental legal framework and its implementation by strengthening the regulatory capacity of the government, and by enhancing the capacity of CSOs and scholars to hold the government accountable for its regulatory performance.

This project aims to explore the environmental impact of early Roman expansion (4th/3rd century BC) through a program of dating and ecological sampling of traces of field systems (centuriations).

The state of our environment is a global concern. Despite an increasing awareness, setting internationally binding and ambitious commitments has proven to be a very difficult process. Can unilateral trade measures form an alternative and contribute to global environmental protection?

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.
