This research aims to design a toolkit that helps governments in guiding and assessing maritime companies to implement blue economy principles for supporting the achievement of sustainable development goals (SDGs) in coastal states. Currently, there are 153 of 193 United Nations member states which are coastal. Coastal states are playing an important role in ocean economy development in the world while have been impacted by many environmental problems. The environmental, social, and economic aspects should be considered in blue economy business to reduce ecological scarcities and environmental risk, to improve food security, human well-being, quality jobs, poverty eradication, economic growth, also to ensure sustainable production and consumption. To support blue economy business in coastal states, a toolkit of the Blue Economy Company Index (BECdex) has been designed. BECdex would be able to assess and guide maritime companies to implement blue economy principles and achieve the relevant SDGs. Maritime companies are profit organizations that operating their business in blue economy sectors and taking place in the ocean and coastal areas. The methodology used in this research includes designing a structure of the index through selection, classification, and modification from the existing blue economy concepts to set the aspects, outcomes, principles, and indicators of BECdex and mapping the index to SDGs. Besides the index scoring formula had been created. BECdex can classify maritime companies into three categories of labeling, namely Excellent Blue Economy Company, Good Blue Economy Company, and Standard Blue Economy Company based on their implementation of BECdex indicators. The indexing will be conducted on a website. Finally, this toolkit is expected to be an innovative solution to encourage companies in blue economy sectors to voluntarily implementing the blue economy in supporting the achievement of SDGs in coastal states.
