Despite the City of Turku’s ambitious plans of reducing greenhouse gas (GHG) emissions per capita by 2020 by 30%, compared to 1990 levels, a rise in population resulted in a peak in emissions levels at the turn of the millennium. As a result, the City Council decided to set its procurement of electricity on a new course, sourcing all their requirements from renewable energy. Turku’s new contract – covering all electricity the City purchases – began in 2013. An interesting result of the tendering process was that the green electricity requirement had a minor impact on the purchase price, thus encouraging the city to continue seeking green procurement. Its electricity is now produced from 100% certified renewable sources. Turku's GHG emissions are expected to decrease by 31,000 tonnes a year (2% of total emissions). In terms of the origin, a large proportion of the electricity provided under the contract is generated by hydropower, but part of the mix used by the energy company also includes wind and biomass.
