In recent years, people become more aware of the impact of food production on the environment and increasingly want to change their food to minimize the impact of their diet on the planet Earth. To make this possible it is necessary to know the exact impact of certain types of food of animal origin on the environment. This paper presents greenhouse gas (GHG) emissions as well as the intensity of greenhouse gas emissions associated with the production of different poultry species in Croatia over the last decade (2010 - 2020). Greenhouse gas emissions were calculated using the Intergovernmental Panel on Climate Change (IPCC) methodology for conditions in Croatia. As the birds do not have the highest GHG emission within animals, emissions from enteric fermentation, only CH4 and N2O emissions from manure management in poultry production were considered. Between the years 2010 and 2020, total emissions of CH4 from poultry production were increased by about 12%, at the same time N2O emissions increased by 53%. The changes, that is, an increase in GHG emissions can be attributed to the total number of poultry in Croatia, which increased by 38%. According to the Central Bureau of Statistics, apart from the total number of poultry in the last ten years, there has been a significant change in the proportion of certain poultry species. This primarily refers to broilers and laying hens, which have changed their annual population average from 3.1 to 9.2 million broilers or 5.0 to 2.8, million laying hens. Emissions in other poultry species have been declining significantly, as the number of animals has also been declining. Poultry production in the Mediterranean and continental parts of the Republic of Croatia did not significantly affect the total GHG emission in Croatia. Poultry production in the Mediterranean part represents only 7% of total poultry production in Croatia. |
