The city of Graz subsidizes solar collector installations that
provide hot water for household heating and use, offering
€ 100 per m² of installation costs up to 30 m². To find out
their roofs’ solar potential, citizens use Graz’s online solar
roof app. Photovoltaic installations are subsidized at € 500/
kWp up to 5 kWp.
The city of Graz offers financial benefits for building owners
who switch their heating to district heating systems. For
heating installations within apartments, subsidies between
30 and 100% of recognized investments are provided according
to beneficiary income. Standard single-family residential
installations including water heating are also subsidized
regardless of owner income.
In July 2011, Graz’s city council approved a “District Heating
Implementation Plan” (Communal Energy Concept 2011),
part of the City Development Concept (4.0 STEK; §21(3) lit
5 StROG 2010). It allows the city of Graz to make district
heating compulsory under certain conditions and move toward
long-term air quality health in a particularly polluted
area. As a consequence, two areas have been legally designated
for compulsory connection to the district heating
Climate-change adaptation measures require farsighted, intelligent
planning for the future. The “Smart City Graz Mitte”
Project seeks to demonstrate new urban energy concepts as
part of innovative, sustainable city development. A mixeduse
400-hectare urban quarter is to be transformed into an
environmentally friendly, livable and intelligently developed
neighborhood. In 2012, task forces for key project phase-1
areas and milestones have been defined; in-detail planning

Frequent floods (e.g., 2005 and 2009) led to the assumption
that climate change in general is increasing heavy rainfall
in Austria. The “Graz Rivulet Program” seeks to provide
the best possible flood protection over a ten-year period at
the same time it sets up ecological and recreational benefits.
In 2012, the previous ten years’ flood protection work continued
on specific Graz area rivers.
City of Graz has reported 1 Community emission inventory, since 1994. In its latest inventory, compiled in 1994, the "Stationary energy", "Transport" and "Agriculture, forest and other land use" are identified as key emission sources.
