Do you know of a particularly effective or innovative approach for changing behaviors related to climate change mitigation or adaptation, energy conservation, or sustainable transportation? Your own program? Nominate it for Landmark designation. Designation as a “Landmark” (best practice) case study through this no-cost peer selection process recognizes behavior change programs and approaches considered to be among the most successful, innovative, replicable and adaptable in the world. Designated programs gain exposure and credibility, and we prepare and post detailed on-line program case studies, which may help them respond to requests for information, attract customers and investors, and/or maintain or increase program funding.
