This paper provides a conceptual context for exploring how oil and gas majors can shift from dirty fuels to clean energy forms. This energy evolution has become critical as climate change concerns challenge oil and gas corporations' future existence. In these socio-technical milieus, the Danish Oil and Natural Gas Company (DONG Energy) has evolved from a fossil-dominated undertaking to a green energy company, Ørsted. Thus, the paper introduces the concept of 'oil and gas majors transitioning' (OGMT), situates it within the 'energy transition' and 'energy transition governance' normative frameworks, applies it to the evolutionary journey of Ørsted as a case study, and provides insights on how other fossil fuel undertakings can also govern a possible transition to a green energy economy. The study suggests that mainstream oil and gas companies have great potential to transition to clean energy portfolios by optimising organizational steering, technical leverage, and intra- and inter-industry synergies. However, policy support from petroleum-producing host states remains pivotal to the success of OGMT.

本文提供了一个概念背景，用于探索石油和天然气巨头如何从肮脏的燃料转向清洁能源形式。随着气候变化问题对石油和天然气公司的未来生存构成挑战，这种能源演变变得至关重要。在这些社会技术环境中，丹麦石油和天然气公司 (DONG Energy) 已从一家以化石为主的企业发展成为一家名为 Ørsted 的绿色能源公司。因此，本文介绍了“石油和天然气巨头转型”（OGMT）的概念，将其置于“能源转型”和“能源转型治理”规范框架内，并将其应用于 Ørsted 作为案例研究的演变之旅，以及提供有关其他化石燃料企业如何管理向绿色能源经济的可能过渡的见解。该研究表明，主流石油和天然气公司通过优化组织指导、技术杠杆以及行业内和行业间的协同作用，具有向清洁能源投资组合转型的巨大潜力。然而，石油生产东道国的政策支持仍然是OGMT成功的关键。
