- Sustainability and sustainable development are amongst the largest and most complex challenges for the 21st century. This is not just a matter for states and governments, but rather a common goal to which we should all contribute. Are the rules of private law suitable to contribute to sustainable solutions? The authors in this book explore aspects of property law, tort law, and contract law. They investigate whether the current rules of private law provide sufficient incentives and possibilities for sustainable action, or whether these rules require reform. This research is part of a joint research project of the Maastricht European Private Law Institute (M-EPLI), in which researchers from various fields work together on large societal issues. Through seminars, discussions and joint research, M-EPLI researchers aim to cross boundaries between their respective fields and contribute to solving large societal challenges.
