In Jeju Island, Korea, a demonstration complex for smart grid technology was established to demonstrate the efficiency and feasibility of five fields, such as ‘smart place’, ‘smart transportation’, ‘smart renewable’, ‘smart power grid’, and ‘smart electricity service’. The demonstration of the efficiency and feasibility of this technology ended in May 2013 and now the second stage projects are proceeding to expand the scope of the above fields. Also, Dae Kyung Engineering Co., Ltd., one of the professional engineering businesses in Jeju Island, is steadily expanding its green industry domain in the ‘smart renewable’ and ‘smart transportation’ fields by establishing consortiums with major companies. I would like to introduce how a small and local company’s passion for a ‘green’ technology led to establishing ‘green’ communities and inducing changes in the world through developing ‘green’ technologies. A case of ‘Gapado (Gapa Island)’ which is a small island belonging to Jeju Island is quite relevant example of this kind of change and experience. Gapado has become a green island and dreamt about making the world greener through the networks with other islands and local governments around the world. In the future, the International Green Island Forum Corporation will hold forums on environment and green technologies regularly and build networks with local governments at home and abroad and businesses which aim at supporting ‘green and carbon-free islands’. Through this, the forum will contribute to conserving islands’ unique ecology and culture and pursue development in island areas using new and renewable energy and realizing where no carbon is emitted. We are looking forward to seeing people all around the world who dream green islands, and eco cities join forces with us.
