Decarbonization policies are being stymied by political conflict. Local communities might oppose decarbonization infrastructure such as solar farms, mines, or transmission lines if they view these projects as imposing high costs on them in relation to their benefits. To decarbonize, the automobile industry seeks to shift from the internal combustion engine to electric vehicles, which require lithium-based rechargeable batteries. In the United States, to meet the increasing lithium demand through domestic sources, there is a proposal for a lithium mine in Thacker Pass, Nevada, which faces strong opposition from native nations and environmental groups. Using a representative sample of Nevada residents (n = 1,368), we explore if proximity to the Thacker Pass mine and to any Nevada mine influence public support for the proposed lithium mine. In addition, we test three frames that emphasize different benefits of the proposed mine: climate policy, national security, and local economic development. We find that respondents living closer to the Thacker Pass mine tend to be more supportive of the proposed lithium mine but exposure to existing Nevada mines does not affect public support. Among the treatment frames, only the national security frame increases public support. This suggests that to navigate local public opposition, the national security-domestic sourcing of key inputs required for decarbonization, aspect of decarbonization projects should be highlighted.
