The present study intends to analyse the Corporate Social Responsibility (CSR) practices of companies operating in a global environment. On the one hand, it identifies the requirements contained in CSR guidelines and standards, developed by different international institutions. On the other hand, empirical research is conducted focused on Spanish companies with operations and/or suppliers in developing countries. In particular, we analyse the CSR practices reported by Spanish companies that joined the Global Compact, taking as an information source their Communication on Progress Reports corresponding to the year 2007 (60 companies). The results of this analysis show the CSR performances of the studied companies with regard to issues like human rights, labour rights, environment and corruption.
