Which executive agency is involved with smart, green, and integrated transport initiatives?

The correct choice refers to the "Innovative and Executive Agency" (INEA), which is specifically tasked with the management of the European Union's funding programs aimed at supporting infrastructure projects, including those that promote smart, green, and integrated transport initiatives. These initiatives align with the EU's goals of enhancing transportation efficiency, sustainability, and connectivity across member states. INEA plays a crucial role in facilitating projects that are at the forefront of technological innovation in the transport sector, thereby contributing to the overarching objectives of the EU's transport policy.

The other agencies mentioned have different focuses. For instance, EASME primarily supports small and medium-sized enterprises and does not specifically focus on transport initiatives. ERCEA deals with the European Research Council, which is more concerned with research in various areas rather than transport per se. INAE focuses on broader aspects of energy and climate, which can touch on transport but does not have the direct emphasis on initiatives related to integrated transport systems.
