As the impacts of climate change and global demand for marine resources have increased, the development of an integrated, holistic marine governance framework has become a key goal for both the EU and US. Recent policy events on both sides of the Atlantic provide a window of opportunity to significantly improve marine governance in national and international waters. To this end, the Ecologic Institute led a transatlantic project team that convened a multi-stakeholder dialogue allowing experts from the EU, US and other regions to develop best practices for integrated marine management.
