In recent years and at COP26, India and California have demonstrated continued global climate leadership, including joining the ZEV Transitions Council to advance ZEV adoption and promote international cooperation. Both regions are hubs of innovation and offer important lessons on using creative policy design and strategic public institutions to accelerate EV deployment. A California-India ZEV Partnership will provide the opportunity to explore sub-national policy design as a lever for vehicle electrification, and importantly, harness the role of states as laboratories of innovation in both the US-India context as well as the global south.
