Abstract:
Worldwide, more than 1.3 billion tonnes of food are wasted each year, which is equivalent to releasing 4.4 Gt of CO2 equivalents (CO2e). In this context, the Food Bank of Navarra (FBN) annually avoids the waste of approximately 3000 tons of perfectly consumable food. The aim of this study was twofold: on the one hand, to analyse the carbon footprint of the FBN and, on the other hand, to perform a comparative analysis of the greenhouse gas (GHG) emissions in two scenarios, \"with\" and \"without\" the actions of the FBN, in order to identify and quantify the environmental benefits, in terms of GHG emissions reduction, associated with the reduction in food waste. The analyses were conducted in two different years. The carbon footprint associated with the FBN\'s activities was 147 t of CO2e in the year 2018. The quantification of GHGs in the scenario \"without the FBN\" showed that if the FBN did not exist 4715 t of CO2e would have been emitted. The results obtained in consecutive years were similar, highlighting the importance of the FBN-not only in social terms but also environmental terms-as it prevented a large amount of GHGs from being emitted into the atmosphere. A detailed account of the carbon emission reduction associated with the food bank\'s operations and the knowledge of the benefits involved could boost their positive effects in facilitating the integration of their activities into policies aimed at climate neutrality.
摘要:
全球,每年浪费超过13亿吨食物,相当于释放4.4Gt的CO2当量(CO2e)。在这种情况下,纳瓦拉食品银行(FBN)每年避免浪费大约3000吨完全可消费的食物。这项研究的目的是双重的:一方面,分析FBN的碳足迹,另一方面,对两种情景下的温室气体(GHG)排放进行比较分析,“带有”和“没有”FBN的动作,为了识别和量化环境效益,在减少温室气体排放方面,与减少食物浪费有关。分析是在两个不同的年份进行的。2018年,与FBN活动相关的碳足迹为147吨二氧化碳。在“没有FBN”的情况下,温室气体的量化表明,如果FBN不存在,将排放4715吨CO2e。连续几年获得的结果相似,强调FBN的重要性-不仅在社会方面而且在环境方面-因为它阻止了大量的温室气体排放到大气中。详细说明与食品银行的运营相关的碳减排以及对所涉及利益的了解,可以增强其在促进将其活动纳入旨在气候中性的政策方面的积极影响。
