Corporate Social Responsibility (CSR) is a growing concern both among companies and among stakeholders. Stakeholders have become more interested in the consequences of business activities and therefore companies must engage in socially responsible behaviour in order not to lose the trust of society. This is one of the reasons why CSR is now so important and this is why it is something that cannot be forgotten. CSR is voluntary by nature and this means that companies cannot be forced to be socially responsible. Stakeholders, however, can try to influence business decision and foster the adoption of an ethical philosophy. This thesis wants to address how governments are trying to support companies that want to become socially responsible and how institutions are trying to promote CSR. Special attention is being paid to the most important initiatives to promote CSR in the European Union, in the United Kingdom, in Italy, and in Switzerland.
