The paradigm of corporate environmental disclosures aimed at investors developed in 2017 with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations. Existing literature on social responsibility disclosures points to gender diversity on the board of directors as an influencing factor. This study aims to assess the influence of gender diversity in climate-related financial disclosures, as recommended by the TCFD based on a sample of 27 companies operating within the sectors of electricity, oil, coal and gas, water, and alternative energy that have announced their adherence to the recommendations from 2017 to 2021. By applying a linear regression model, the results indicate the presence of a positive association between the level of TCFD disclosures and board gender diversity, as well as other factors, such as company size, CEO duality, and general liquidity. However, the influence of board gender diversity on corporate reporting based on the TCFD recommendations suggests that the commitment of boards to the reporting of climate change risks and opportunities is not significantly dependent on gender diversity, as the presence of women in the Boards is favorable for the reporting but without a significant impact on the level of disclosures. This research offers insights into sustainability reporting practices, focusing on a relatively new perspective of reporting climate-related financial topics and their determinants. The findings hold implications for organizational leaders and stakeholders, mainly investors, as these recent sustainable reporting practices are challenging but also bring new opportunities related to transparency towards climate-related issues.
