Chios

Chios is a Greek island, located northeast in the Aegean Sea. It is the fifth in size island of Greece with a surface area of 842.29 km2. Chios has a population of approximately 51320 inhabitants. The total length of Chios coastline reaches 213 km. Chios is notable for its exports of mastic gum and the island is also known as "the Mastic Island". 

Chios is not interconnected yet to the mainland and electricity is mainly produced by diesel generators while about 11% of electricity comes from renewable energy sources on the island. A significant source of CO2 emissions comes from diesel and petrol powered transport on the island while another significant source of emissions is maritime and air transport to and from the island.

The municipality of Chios, having in mind a vision on clean energy transition, participates in various national and European programmes that aim to reduce carbon dioxide emissions. It is also implementing projects for the reduction of energy consumption of individual municipal buildings, school complexes, the replacement of light bulbs of street lighting with photovoltaic lighting elements and recently, the electrification of public transport.

In this direction, Chios has developed its Clean Energy Transition Agenda between 2021-2022 as part of the technical assistance received from the Clean energy for EU islands secretariat. In addition, the island already puts planning into action through a new project on circular and sustainable desalination, again by taking advantage of the second round of technical assistance provided by the Islands secretariat in 2022.
