On July 31, the European Commission adopted the first set of rules under the European Sustainability Reporting Standards (ESRS).^[1] The ESRS is an important follow-up to the adoption of the Corporate Sustainability Reporting Directive (CSRD) in January by the European Union (EU). CSRD requires EU and non-EU companies with activities in the EU to file annual sustainability reports. EU companies—including EU subsidiaries of non-EU companies—will file reports prepared in accordance with ESRS.
