A group of more than 20 environmental organizations developed a concise guide to the science-based principles and priorities for environmental monitoring that are crucial to advance responsible offshore wind development in the United States. The new guide, which NRDC helped develop, offers two levels of recommendations: 1) Monitoring priorities common to all geographic regions where offshore wind is being developed; and 2) Monitoring priorities specific to individual geographic regions to account for unique regional considerations. The guidance document will be periodically updated to incorporate additional regions and to reflect the latest scientific and technological advancements.
