The aim of the 4-year project is to use greenhouse gas emission data calculated from atmospheric measurements to help refine national emission inventories based on activity statistics. The project focuses on eight European countries, including Hungary. The project places particular emphasis on methane (CH₄), nitrous oxide (N₂O) and halogenated gases (F-gases), which play a key role in the atmospheric greenhouse effect.

The greenhouse gas monitoring station maintained by ATOMKI at Hegyhátsál is one of the stations on which the project bases. Here, atmospheric concentration of nitrous oxide is continuously measured and air samples are taken for F-gas analyses. The emission data calculated from these measurements is shared with the national organizations responsible for the emissions inventories.

The project is being implemented within the framework of a consortium. The 17-member consortium of 8 countries is led by Utrecht University. The total funding for the project is 3,526,154.50 EUR, of which ATOMKI will receive 178,000 EUR.
