This chapter examines the crucial role that innovative strategies adopted by energy companies play in the decarbonization of the transport sector. As climate change mitigation becomes an urgent global priority, and the European Union tightens its regulations and environmental policy frameworks, a coordinated and systemic approach to energy production, distribution, and consumption in the transport sector is becoming increasingly important. Energy companies are emerging as key actors in this transformation, moving beyond their traditional roles to become active drivers of low-emission mobility. Their contributions include the generation and integration of renewable energy sources, investment in energy storage technologies and smart grids, and the development of electric vehicle charging infrastructure. Furthermore, energy companies are engaging in cross-sector collaboration and digital innovation to support the efficient management of energy flows and mobility services. These initiatives not only reduce greenhouse gas emissions from the transport sector but also enhance energy security, system flexibility, and economic resilience. By implementing comprehensive and forward-looking innovation strategies, energy companies are accelerating the transition to sustainable transport, aligning business practices with climate goals, and responding proactively to market and policy changes. This study highlights the strategic importance of the energy sector’s involvement in shaping a carbon-neutral future for transport, thereby contributing to a more sustainable and resilient mobility ecosystem at both national and European levels.
