Abstract

S obzirom na povećanu svijest o globalnom zatopljenju i crpljenju resursa, razni su načini pokušaja smanjenja opterećenja na planet. Biljna prehrana je predstavljena kao jedna od mogućih rješenja, jer u odnosu na životinjske proizvode ima znatno nižu emisiju stakleničkih plinova koji doprinose zagrijavanju planeta. U ovom radu objašnjene su razlike u emisiji CO₂ kod hrane biljnog i/ili životinjskog podrijetla. Cilj je pokazati kako isključivo biljna prehrana nije nužno i najodrživija. Analizirana su tri tipa jelovnika, ovisno o omjeru biljne i životinjske hrane prisutne u njima. Najveću emisiju CO₂ imao je jelovnik u kojem dominira meso, ali najmanji onaj koji se svrstava u kategoriju fleksitarijanskog, a ne isključivo biljni. Također je korekcijama svakog jelovnika uvođenjem lokalnih i sezonskih namirnica utvrđeno smanjenje CO₂ ekv za 48,8% u fleksiterijanskom jelovniku, 38,4% za mesni jelovnik te 9,4% u jelovniku koji je isključivo biljni. Ovo je svakako potvrda nužne edukacije populacije kako se i malim promjenama može i korekcijom prehrambenih navika, manje opteretiti planet

Abstract (english)

Given the increased awareness of global warming and resource depletion, there are various ways of trying to reduce the burden on the planet. Plant-based nutrition is presented as one of the possible solutions, because compared to animal products, it has a significantly lower emis-sion of greenhouse gases that contribute to the warming of the planet. This paper explains the differences in CO₂ emissions from food of plant and/or animal origin. The goal is to show that an exclusively plant-based diet is not necessarily the most sustainable. Three types of menus were analyzed, depending on the ratio of plant and animal food present in them. The menu dominated by meat had the highest CO₂ emissions, but the one classified as flexitarian, not exclusively plant-based, had the lowest. Also, corrections to each menu by introducing local and seasonal foods resulted in a reduction of CO₂ eq by 48.8% in the flexitarian menu, 38.4% for the meat menu, and 9.4% in the exclusively vegetarian menu. This is certainly a confirma-tion of the necessary education of the population that even with small changes and by correcting eating habits, the planet can be less burdened.
