Current climate change is based on growth of greenhouse gas emissions, which are mainly due to human activities. Activities related to the global food system are responsible for about fourth of the global greenhouse gas emissions. Thereby, the emissions of the food system, which are related to the products that it provides, should be decreased. Greenhouse gas emissions of products can be estimated and communicated by the indicator of carbon footprint, whereas reduced greenhouse gas emissions of the products’ users, resulting from the emission improvements related to the products, can be presented by the carbon handprint. The aim of this master thesis was to calculate the carbon footprint of a Finnish food business’ meat containing food product. In addition, the food product’s meat component was replaced with different meat alternatives in order to assess the carbon handprints, and to compare the carbon footprint and carbon handprint as information providers of climate impacts. The main method used in this thesis was life cycle assessment, while methodology of carbon handprint was used as an additional method. Life cycle assessment was used to assess the carbon footprint, and it was applied according to the ISO standards of 14040 and 14044. Primary data for the study was collected from the Finnish food business through interviews by phone and e-mail, while secondary data was gathered from different sources. The actual calculation process of the carbon footprint and carbon handprints were executed by using Excel. The carbon footprint of the studied food product was found to be 1,20 kgCO2eq/one packaged food product, while the handprints based on the meat alternatives were found to be 0,27-0,39 kgCO2eq/one packaged product. Carbon footprint and handprint were found to be different as communication tools of climate impacts. In addition, they were discovered to have their advantages and limitations depending on the chosen point of view.
