Particularly at the regulatory and economic level, it is increasingly the case that companies must fulfil their responsibility for human rights and environmental protection along their transnational supply chains. Svenja Kirstin Langenhagen analyses the interplay between Corporate Social Responsibility (CSR) and the UN Convention on Contracts for the International Sale of Goods of 1980 (CISG), which, due to its character as a uniform law, potentially governs more than 80% of international sales and thus offers the opportunity to create a new international economic order in terms of CSR and transnational supply chains. In addition to the economically analysed question of the practical applicability of the CISG in the field of CSR, she examines the interactions of private law and human rights law with regard to the conformity of goods, the buyer's obligation to give notice of defects and the buyer's remedies, as well as the question of the seller's exemption from liability.
