The Rostock Energy Alliance (Energiebündnis Rostock) was founded in April 2011 by the City of Rostock and nine other municipal stakeholders from sectors such as public transport, housing and waste and water management. Their united goal is a locally based energy supply fully sourced from renewables. While CO2 emissions should be reduced, quality of life should not. The Alliance meets face-to-face biannually to exchange knowledge and experience, as well as to seek synergies for various constituent activities. The Alliance aims to reduce the annual CO2 emission per person to 2.5 t or less by 2030. Compared to 2010, this is equal to a 2 % reduction per year. To date (2015), the Energy Alliance supported the city in the creation of an energy transition concept and the current implementation of associated measures, in addition to the foundation of an energy cooperative.
