This proceedings volume combines chapters derived from papers presented at the 4th and 5th Annual Conferences on the Future of the Commercial Contract in Scholarship and Law Reform. This ongoing research project brings together scholars from all over the world at an annual international conference in London. The book focusses on technology in commercial contract law as well as on sustainability in commercial contracts. The latter theme was inspired by the United Nations' climate conference that was to take place in Glasgow in the United Kingdom that same year. The book combines topical current issues in commercial contract law and practice organized in three parts. The first part contains contributions to the area of law and technology. The second part of the book expands on aspects of sustainability understood as environmental reasonableness in the context of commercial contracts. The third part includes several chapters on the topics of supervening events and contractual ethics. This book is therefore part of a coherent line of contributions to the furthering of modern contract theory. The choice of topics is closely following current issues of legal policy and contract practice.
