Air Emission Data system - IPTJ
The Air Emission Data System (IPTJ) includes data on national air pollutant and greenhouse gas emissions. The data can be searched by substances, source sectors, geographical locations and years.
The Finnish Environment Institute receives a broad range of information from various sources and based on this information calculates or compiles data on all air pollutants, including greenhouse gases in the energy and waste sectors (Figure 1). In cases where industry-reported data are available from the VAHTI data system, this information is used instead of the calculative data in the IPTJ for the respective processes.
VAHTI is the data system run by the regional environment centres to collect data reported by industry on environmental load, among other things, for supervision purposes.

Data on greenhouse gas emissions from agriculture and land use are processed by Agrifood Research Finland and on carbon dioxide sinks in forests by the Finnish Forest Research Institute.
The source sector categories are based on the UNFCCC (United Nations Framework Convention on Climate Change) and UNECE CLRTAP (United Nations Economic Commission for Europe Convention on Long-Range Transboundary Air Pollution) classifications for reporting requirements.
The Finnish Environment Institute (SYKE) is responsible for compiling the annual emission reports to the UNECE CLRTAP. The Institute also calculates the greenhouse gas emissions from the waste sector, and emissions of F-gases and NMVOCs (non-methane volatile organic compounds) for the inventory report to the UNFCCC. Statistics Finland is the responsible body for this convention.
Information on the annual inventories to both conventions can be found from the web pages of the environmental administration.
