For over five decades, the modern concept of sustainability has evolved along with its implication in almost all spheres, including the engagement of businesses via their Corporate Social Responsibility. The EU has joined international UN endeavors and attempts to progress towards the 17 Sustainable Development Goals (“SDGs”). The EU regime for CSR and CSR reporting is a mixture of hard-law, soft-law and policy measures and has predominantly facultative features. Nevertheless, its backbone is Directive 2013/34/EU, especially Art.19a with a rather general wording about which the case law of the Court of Justice of the EU (“CJ EU”) has not yet developed. The organic shaping of the understanding and application of the CSR reporting has been impacted by the COVID-19 pandemic and related crises translated in EU law measures. Arguably, the COVID-19 pandemic is an unprecedented stress test which has brought new light in the interpretation of the scope of CSR to be reported, perhaps it even takes it into a new dimension.
