This thesis integrates scoring, gamification, and Corporate Sustainability Reporting(CSR) to encourage sustainable behaviours through electronic driving journals. As environmental stewardship becomes increasingly important, the European Union's Corporate Sustainability Reporting Directive (CSRD) mandates greater transparency in reporting environmental, social, and governance (ESG) activities. In this context, driving journals in Sweden, primarily used to distinguish between professional and personal vehicle use, emerge as a critical factor in influencing sustainable practices. The study explores the potential of scoring and gamification, which involves incorporating game-design elements into non-game contexts to transform routine compliance activities into engaging processes that promote sustainable behaviour. By combining these journals with the requirements of the CSRD, the research examines their effectiveness in fostering an environmentally conscious driving culture among corporate fleets and individual users. The study employs a multidimensional approach, which involves conducting a comprehensive literature review, analysing the market, and practically applying the findings with Northtracker, a leading driving journal provider. The goal is to examine how aligning Northtracker's systems with CSRD guidelines can help promote and comply with sustainable practices by enhancing user engagement. The results indicate that incorporating scoring and gamified elements within driving journals can effectively increase user participation and compliance, leading to a measurable reduction in environmental impact resulting from improved driving habits. Nonetheless, the study highlights several challenges, such as privacy concerns, data accuracy, and user acceptance, which require a balanced approach to scoring and gamification in sustainability initiatives. The thesis concludes by recommending strategic actions that policymakers and corporations can take to exploit this integration's potential fully. These implications go beyond the immediate scope of driving journals and offer valuable insights into the broader application of scoring and gamification in environmental sustainability efforts.
