Ultimately, it is human behaviour that determines emission levels. Mobility, energy consumption, industrial and agricultural production and consumption patterns are the principal contributors. On the other hand, it is the development and resolute use of clean technologies that reduces emissions. This process can be supported by tightening limit values and providing economic incentives, such as the CO2 levy on fossil fuels that was introduced on 1 January 2008.
The principal sources are transport, industry, households and agriculture (emissions 2008).
