Особенности оценки углеродного следа в сельском хозяйстве: сравнительный анализ методических подходов

Abstract

The study of the components of the carbon balance and the possibilities of its regulation for different types of land use is an urgent scientific task within the framework of the global problem of increasing concentrations of greenhouse gases in the atmosphere and the development of the concept of carbon neutrality. In this article, an assessment of the carbon footprint of the farm was carried out based on an analysis of the capabilities of carbon calculators Cool Farm Tool, AgRe-Calc, Farm Carbon and Ex-Act V9.4, as well as the Methodology for quantitative determination of greenhouse gas absorption volumes, approved by Order of the Ministry of Natural Resources of the Russian Federation No. 371 dated 05/27/2022. Calculations were carried out using the example of the farm located in the Burlinsky region of the Altai region. The results of the study showed that the largest carbon footprint of the considered farm is formed by the cultivation of flax, somewhat smaller by sun-flower and wheat crops, and the lowest by fodder crops. Differences in estimates based on different methods are recorded not only in the resulting total carbon footprints, but also in the structure of the carbon footprint for each crop. In general, in Russia and abroad there are different approaches to determining the carbon footprint. The approach used in carbon calculators assumes that all carbon generated in one way or another during economic activity forms a carbon footprint, while the 2022 methodology of the Ministry of Natural Resources also takes agriculture into account as an important sink and carbon reservoir.
