This study explored how managers’ environmental values, leadership, and stakeholder engagement impact environmental sustainability and corporate financial performance in the Philippines’ oil and gas industry. Given the country’s vulnerability to climate change, oil and gas companies face pressure to adopt sustainable practices, with managers playing a crucial role in these efforts. Using a quantitative approach, the study surveyed managers in the oil and gas industry, assessing their environmental values, leadership, stakeholder engagement practices, and both environmental and financial performance. The key findings indicate that managers’ environmental values directly influence environmental sustainability and stakeholder engagement, environmental leadership does not directly impact environmental sustainability but has a significant indirect effect through stakeholder engagement, stakeholder engagement directly affects environmental sustainability and indirectly influences financial performance via environmental sustainability, and strong environmental sustainability leads to positive financial performance. These results underscore the importance of fostering managers’ environmental values and their ability to engage stakeholders in sustainability efforts. Effective leadership relies on collaboration with stakeholders rather than individual actions. This study enhances the understanding of environmental sustainability in the Philippine oil and gas industry and suggests focusing on developing managers’ environmental values to improve sustainability outcomes.
