The special environmental license plates are the only specialty plates sold in Massachusetts that exclusively fund environmental programs. The Right Whale & Roseate Terns, the Leaping Brook Trout, and the Blackstone Valley Mill plates represent the diversity of Massachusetts ecosystems. From the coasts and estuaries to the inland streams to the urban rivers, every person in Massachusetts feels the impact when waters are degraded. The plates are available from the Registry of Motor Vehicles .
