Society for Sustainable Development Design (DOOR) is a civil society organization founded in 2003 with the mission to promote sustainable development principles in all segments of society, at the local, regional and national levels, primarily in the field of energy.

DOOR’s aim is to contribute to achieving a just and carbon-neutral society, adapted to climate change, in which the public takes part in delivering, monitoring, and evaluating public policies, and sustainable energy plays an important role in social, economic, and ecological development and decreasing poverty.

The organisation has successfully implemented more than 100 projects with topics ranging from climate change mitigation, encouraging citizens’ participation in sustainable energy policy-making, improving education about renewable energy sources, and alleviating energy poverty. Door has 14 employees, 60 members, and depending on current activities and requirements at times over 20 active volunteers.
