This tracker is a living dataset, and it gets stronger with community input. Know of a local, state, or national data center opposition movement that isn’t listed here — or have a correction or an additional source for an existing entry? Please get in touch: to.jaewook.lee at gmail
When reporting a movement, it would be very helpful to include: where it is (county and state), when it began, any key dates (hearings, votes, bills, protests), the groups or officials involved, and at least one link to a news article or official record so the entry can be verified.
Research collaborations are also very welcome – especially if you have expertise in topics like American political economy, environmental politics, or social movements. Please feel free to reach out with ideas or contributions.
