The research discusses management decisions made for corporate sustainability. The research is based on analyzing and synthesizing elements of the responsible decision-making process. To achieve the research goal, the authors summarized the practices of sustainable development and existing studies of cognitive and behavioral economics, which made it possible to track the process of environmental responsibility in decision-making. The research characterizes greenwashing commonly seen in sustainable development, covering everything from intentional marketing techniques to cognitive distortions in decision-making. Digital ESG data analytics systems aid in verifying the process of making responsible decisions. The authors proposed a solution for potential financial support to distribute these digital systems. The authors proposed an algorithm for screening ESG data and choosing environmentally responsible solutions in corporate accounting. The continuation of research in the field of responsible decision-making is actualized by the verification of such decisions for the purposes of corporate accounting and global response to climate change.
