CORIN-Asia Foundation in collaboration with the Electric Vehicle Development Center, Prince of Songkla University (PSUEV) has conducted research and development on innovative electric engine for long-tail boat . The project was funded by the National Innovation Agency (NIA). The objective of this project was to  reduce carbon dioxide emissions from long-tail boat transportation by replacing combustion engine with appropriate electric engine. The coastal area of ​​Songkhla Lake, the Gulf of Thailand  coast, and the Andaman coast were used as the study areas. The research result reveals that the developed electric engine for long-tail boat can reduce carbon dioxide emissions by 25 times or 42.04516 kg CO2eq. and reduce cost from the original combustion engine by more than 85% or reduce energy costs by 27 times (comparing the usage distance of 20 kilometers). This electric engine for long-tail boat is suitable for using in community tourism. It is an initiative to solve the pollution problem and reduce the impact on the community from engine noises. It also promotes sustainable tourism business by attracting tourists who travel in the style of “Low Carbon Tourism”.  Furthermore, it is an opportunity for trading carbon credits in the future. The research results have been expanded to target groups in the areas of  Surat Thani, Nakhon Si Thammarat and Ranong Provinces.  Recently, CORIN-Asia Foundation has been assigned by the Governor of Satun Province to develop a model for using electric boats to reduce carbon emissions in transportation within the Satun Global Geopark area.
