During the 2010s, mandatory disclosure of extra-financial information in France has been encouraged by five major laws passed to reinforce corporate social, environmental and climate responsibility of systemic actors, key to the transition process to a low-carbon, circular and sustainable economy. Whether these laws are paper tigers is of the utmost importance in understanding, notably, how firms disclose when disclosure is mandatory. Considering laws as linguistic formulations and their meanings, we provide a qualitative analysis of Universal Reporting Documents of some of the largest publicly traded French companies (CAC40). We demonstrate that this intense regulation period has fostered a common language, instilling an environmental and climate reporting culture. In addition, based on a variety of accountability profiles - responsiveness-oriented, controllabillity-oriented, and out-of-step firms -, we highlight diverse dynamics as to the appropriation of the successive laws, along with private and institutional standards.
