  Understanding global climate change and finding ways to curb it is one of the greatest scientific challenges of our time, a number of studies examining the climatic effects of agriculture, including animal husbandry. Analyzing the most common methods of studying the climatic effects of animal husbandry, we can say that each method has its own shortcomings, their practical application is often difficult, and their results can be contradictory. In articles examining CO2 emissions from grasslands, we often come across results that contradict basic in-kind observations. In my opinion, it is worthwhile to define exactly what is meant by animal husbandry in the research on the topic, as there is no uniform conceptual definition, and in the future it would be expedient to develop a method for calculating GHG emissions from small livestock farms.

  The aim of our study is to find the most appropriate method for examining the impact of small, extensive livestock/mixed farms on climate change. We would like to describe a self–developed calculation, the application of which requires basic mathematical knowledge. With the method, we get an analysis that can be prepared in a short time, either in the case of real farms or model farms that exist in theory. In order to use it, a detailed description of a farm must be prepared, with the help of a year's work process, annual purchases and the summation of annual production. By drawing conclusions from the obtained results, the farm's GHG emissions can be optimized, and it can also help to find climate–neutral farming methods for the production of animal products.
