Hungarian National Inventory Report for 2005

Pursuant to the UN Framework Convention on Climate Change (UNFCCC), Hungary has been preparing annual inventories of greenhouse gas emissions using the IPCC methodology since 1994. Due to the drastic reduction of production in the energy sector, industry and agriculture in the beginning of the 1990’s, the average of 1985, 1986 and 1987 was selected as base year. Base years are used as points of reference for the greenhouse gas reduction program, under which Hungary has undertaken to reduce the emissions by 6 %.

In the early years of inventory preparation, it was problematic to ensure time series consistency because of capacity shortage of the inventory team. Finally, a recalculation project was started in 2003 with the support of the Ministry of Environment and Water.

Additionally, specific national emission factors were determined for a number of technologies thereby increasing the accuracy of the inventories. Eventually, a consistent time series including each of the years of 1985 through 2003 (19 years in total) was generated by early 2005. At the same time, the inventory compilers started using the recently issued CRF reporter program.

As of the 1st of January 2006, the GHG emission inventories have been prepared under the coordination and with the participation of the Ministry of Environment and Water. Later in this year a Greenhouse Gas Inventory Division was established in the Hungarian Meteorological Service (OMSZ).

While in the current inventory cycle the inventory preparation and compilation was a joint effort of the Ministry and the Service, in the future OMSZ will be responsible for all inventory related tasks. The main purpose of this National Inventory Report is to describe the input data and calculation methodologies on which the emissions estimates are based thus increasing the transparency of the inventory.
