The study covers six key marine economic sectors: Fisheries; Renewable energy; Oil and gas; Tourism; Transport; Environment and ecosystem. It highlights that if blue scenarios are applied, Viet Nam’s GDP is estimated to be 34% (or USD23.5 billion) higher and GNI per capita 77,9% higher compared to the business as usual scenario in 2030. Key to unleashing the blue economy is a Marine Spatial Planning Master Plan which UNDP is helping the government design, consult and launch.
