Protect Our Winters is a climate advocacy nonprofit with a negligible operational footprint but no formal sustainability disclosure. Its strength lies in aggressive pro-climate lobbying and public lands advocacy. Core weakness: complete absence of operational emissions reporting, energy strategy, or science-based targets for its own organisation—despite being a climate organisation.
