Helsinki - Helsinki Region Environmental Services Authority
Helsinki Region Environmental Services Authority (HSY) represents the Helsinki Metropolitan Area (Cities of Helsinki, Espoo, Vantaa and Kauniainen) with a population of 1.1 million. Total coverage area is 791 km2 with almost 600,000 jobs. HSY is a regional authority providing environmental services for residents and companies in the Helsinki area. Besides water and waste services, HSY produces reliable and accurate information in order to improve the urban environment. The tasks of the HSY's Regional and Environmental Information unit are air quality monitoring, climate indicators, strategy work on the mitigation of, and adaptation to climate change as well as producing and delivering regional spatial data.
The cities of the Helsinki Metropolitan area (HMA) and HSY have prepared regional climate change mitigation (2007) and adaptation (2012) strategies, both concentrating on the built and the urban environment. The impacts of climate change in the region have also been identified and policies and measures to adapt to these impacts have been defined. Neither mitigation nor adaptation is novel to HMA. However, the environmental knowledge guiding and supporting planning and decision making can always be increased.
One of the biggest challenges in cutting GHG emissions in the HMA is to phase out fossil fuels and in tandem improve the energy efficiency of buildings. Overall, the GHG emissions reach up to 5.1 tCO2e per capita, with over 50 % from the heating of buildings. The DECUMANUS energy efficiency products provide a foundation for meeting this challenge. In various future projects and campaigns, the roof heat loss map and the solar potential map will be used to identify the primary targets for installing renewable energy and retrofitting houses.
By adapting to climate change, the Helsinki Metropolitan Area prepares for the consequences of climate change, such as increased risks of floods, heavy rainfalls, mild and wet winters and drought periods. Minimizing the negative impacts of climate change and benefitting from the positive consequences requires early and planned action and necessary spatial information. In this respect, the green roof potential and the day-time population distribution are valuable additions to our knowledge base.
HSY produces reports and spatial analyses for planning and development in the Helsinki Region. The essential spatial data, metadata and digital maps are made available for the city officials and decision makers. Moreover, as much information as possible is published via HSY’s web-based open data map interface kartta.hsy.fi.
