Thailand has a strategic national policy to increase organic rice farming. This study firstly applied Life Cycle Assessment for evaluating the quantitative environmental impacts at the regional and national levels to facilitate the national policy decision on the expansion of organic rice cultivation areas. The impact categories of interest included global warming, terrestrial acidification, freshwater eutrophication, terrestrial ecotoxicity, and freshwater ecotoxicity, and the life cycle impact assessment method applied was ReCiPe. The results showed that the life cycle environmental impacts from organic rice cultivation in the nine provinces in the North were lower than those from the 12 provinces in the Northeast, due mainly to the higher yields and lower use of fertilizers in the former. The methane emissions in the North (11,147 kg CO2e/ha) were similar to those in the Northeast (11,378 kg CO2e/ha). However, nitrous oxide emissions in the Northeast were higher than in the North due to the higher amounts of fertilizer used. If Thailand expands the rice farming by 50% in the North and by 50% in the Northeast, the greenhouse gas emissions could be reduced from 11,400 to 11,100 kg CO2e/ha, but the impacts of terrestrial acidification, freshwater eutrophication, terrestrial ecotoxicity, and freshwater ecotoxicity could be increased by 0.0257 kg PO4e (95%), 0.508 kg 1,4-DBe (53%), and 33.1 kg 1,4-DBe (17%), respectively. To reduce the global warming as well as other environmental impacts, Thailand should expand rice farming areas to the North. This information could be useful for supporting the policy decisions on which areas the organic rice farming should be expanded in to minimize the potential life cycle environmental impacts.

The number of pet animals in the European Union is increasing over the last decades. Few studies with a limited focus in terms of impacts and life cycle stages exist that assess the environmental impacts of dogs. This paper addresses the entire life cycle of a dog. An LCA study on an average dog was conducted considering the pet food and dog excrements, i.e., urine and feces. Fifteen impact categories were analyzed. An average dog has a climate change and freshwater eutrophication potential of around 8200 kg CO2eq and 5.0 kg Peq., respectively. The main contribution to most impact categories over the dog’s life is caused by pet food. Freshwater eutrophication is mainly determined by the dog´s urine and feces. Feces also have a significant contribution to the category of freshwater ecotoxicity. Impacts increase significantly with increasing weight and a longer lifetime of the dog as well as low collection rates of the feces. This LCA study reveals that pet dogs can have a significant environmental impact, e.g., around 7% of the annual climate change impact of an average EU citizen. Optimizing pet food and increasing the feces´ collection rate can reduce the impacts.

The aim of this study is to assess the environmental impacts of household life cycles in Santiago, Chile, by household income level. The assessment considered scenarios associated with environmental policies. The life cycle assessment was cradle-to-grave, and the functional unit considered all the materials and energy required to meet an inhabitant’s needs for one year (1 inh/year). Using SimaPro 9.1 software, the Recipe Midpoint (H) methodology was used. The impact categories selected were global warming, fine particulate matter formation, terrestrial acidification, freshwater eutrophication, freshwater ecotoxicity, mineral resource scarcity, and fossil resource scarcity. The inventory was carried out through the application of 300 household surveys and secondary information. The main environmental sources of households were determined to be food consumption, transport, and electricity. Food consumption is the main source, responsible for 33% of the environmental impacts on global warming, 69% on terrestrial acidification, and 29% on freshwater eutrophication. The second most crucial environmental hotspot is private transport, whose contribution to environmental impact increases as household income rises, while public transport impact increases in the opposite direction. In this sense, both positive and negative environmental effects can be generated by policies. Therefore, life-cycle environmental impacts, the synergy between policies, and households’ socio-economic characteristics must be considered in public policy planning and consumer decisions.

The production and utilization of fertilizers are processes with known and noteworthy environmental impacts. Direct greenhouse gas (GHG) emissions and a high contribution to water eutrophication due to the nitrogen (N) and phosphorus (P) derivatives are some of the most crucial impacts derived from the overall life cycle of fertilizer use. The life cycle assessment (LCA) has been reliable and analytical tool for the identification, quantification, and evaluation of potential environmental impacts of fertilizers related to the products, production processes, or activities throughout their lifecycle. In this paper, a gate-to-gate LCA approach was applied in order to identify and evaluate the impacts derived from the production processes of nitrate and compound fertilizers the production industry in Northeastern Greece. The results from this study prove that compound fertilizers have a greater impact compared with nitrate fertilizers, contributing up to 70% of the total production impacts. Furthermore, climate change, freshwater eutrophication, and fossil fuel depletion were identified as the most crucial impact categories. Finally, a comparison with relevant LCA studies was conducted, in order to identify the possibility of a consistency pattern of the fertilizer production impacts in general.

National energy models provide decarbonization strategies. Most national energy models focus on costs and greenhouse gas emissions only. However, this focus carries the risk that burdens shift to other environmental impacts. Energy models have therefore been extended by life-cycle assessment (LCA). Furthermore, deep decarbonization is only possible by targeting all high-emission sectors. Thus, we present a holistic national energy model that includes high-emission sectors and LCA. The model provides detailed environmental impacts for electricity, heat, and transport processes in Germany for meeting the climate targets up to 2050. Our results show that renewable energies and storage are key technologies for decarbonized energy systems. Furthermore, sector coupling is crucial and doubles electricity demand. Our LCA shows that environmental impacts shift from operation to infrastructure highlighting the importance of an impact assessment over the full life cycle. Decarbonization leads to many environmental cobenefits; however, it also increases freshwater ecotoxicity and depletion of metal and mineral resources. Thus, holistic planning of decarbonization strategies should also consider other environmental impacts.

Industrial agriculture results in environmental burdens due to the overuse of fertilizers and pesticides. Fungicides is a class of pesticides whose application contributes (among others) to human toxicity and ecotoxicity. The European Union aims to increase organic agriculture. For this reason, this work aims to analyze climate change, freshwater ecotoxicity, terrestrial ecotoxicity, human toxicity, (terrestrial) acidification, and freshwater eutrophication impacts of fungicides and calculate expected benefits to human health (per European citizen) and ecosystem quality (terrestrial) with life cycle assessment (LCA) during crop production. The Scopus database was searched for LCA studies that considered the application of fungicides to specific crops. The analysis shows how many systemic and contact fungicides were considered by LCA studies and what was the applied dosage. Furthermore, it shows that fungicides highly contribute to freshwater ecotoxicity, terrestrial ecotoxicity, human toxicity, and freshwater eutrophication for fruits and vegetables, but to a low extent compared to all considered environmental impacts in the case of cereals and rapeseed. Expected benefits to human health and ecosystem quality after fungicides elimination are greater for fruits and vegetables, ranging between 0 to 47 min per European citizen in a year and 0 to 90 species per year, respectively.

As the world grapples with the COVID-19 pandemic, there has been a sudden and abrupt change in global energy landscape. Traditional fossil fuels that serve as the linchpin of the modern civilization have found their consumption rapidly fell across the most categories due to strict lockdown and stringent measures that have been adopted to suppress the disease. These changes consequently steered various environmental benefits across the world in recent time. The present article is an attempt to investigate these environmental benefits and reversals that have been materialized in this unfolding situation due to reduced consumption of fossil fuels. Life cycle assessment tool has been used hereby to evaluate nine environmental impacts and one energy based impact. These impacts include: ozone formation (terrestrial ecosystems), terrestrial acidification, freshwater eutrophication, marine eutrophication, terrestrial ecotoxicity, freshwater ecotoxicity, marine ecotoxicity, land use, mineral resources scarcity and cumulative exergy demand. Outcomes from the study demonstrate that COVID-19 has delivered impressive changes in global environment and life cycle exergy demand with about 11-25% curtailment in all above-mentioned impacts in 2020 in comparison to their corresponding readings in 2019.

AbstractEvery consumer’s decision has an impact on the environment, and even basic food products such as pasta have an impact due to their high consumption rates. Factors that can be influenced by the consumer include the preparation (cooking), last mile and packaging phases. The last mile has not been considered in most studies but contributes considerably to the environmental impact of pasta. The three phases and their environmental impact on the life cycle of pasta are analyzed in this cradle-to-grave life cycle assessment. The focus of the study lies on the impact categories climate change, agricultural land occupation, fossil depletion, water depletion, freshwater eutrophication and freshwater ecotoxicity. Inventory data were taken from other studies, were collected in cooperation with a zero-packaging organic grocery store in Germany or were gained in test series. Our results show that the preparation of pasta has the greatest environmental impact (over 40% in the impact categories climate change and fossil depletion and over 50% in the impact category freshwater eutrophication), followed by the last mile (over 20% in the impact categories climate change and fossil depletion) and lastly the packaging (nearly 9% in the impact categories freshwater eutrophication and freshwater ecotoxicity). Based on our study´s results, we provide some recommendations for minimizing the environmental impacts of pasta.

Cílem práce bylo posoudit environmentální dopady různých typů zvolených jogurtových kelímků vyrobených z různých materiálů: z plastu, papíru, skla či z kompozitního materiálu. Environmentální dopady byly vyhodnoceny metodou posuzování životního cyklu (z angl. life cycle assessment, LCA). Výsledky práce ukazují, že skleněné a kompozitní obaly jsou horší než obaly plastové, s výjimkou kategorie dopadu Spotřeba fosilních surovin a humánní toxicita. Jako nejlepší vychází plastový obal s K3 dekorací (papír), který ve všech hodnocených kategoriích dopadu vykazuje nejlepší výsledky. V kategorii dopadu Klimatické změny se nejhůř umístil kompozitní obal a obal skleněný. Nejvíce ovlivněnou kategorií je Sladkovodní ekotoxicita, nejvyšší dopady v rámci této kategorie vykazuje obal skleněný a následně kompozitní. V rámci kategorie dopadu Ionizující záření má největší dopad skleněný obal následovaný obalem kompozitním. Na základě výsledků výzkumu bylo zjištěno, že hlavní příčinou dopadů plastových kelímků na životní prostředí je výroba PP granulátu, u skleněných obalů je to výroba samotného skla a v případě kompozitních obalů výroba kompozitního obalu. Abstract (en) The aim of the work was to assess the environmental impacts of different types of selected yoghurt cups made of different materials: plastic, paper, glass or composite material. Environmental impacts were assessed using the life cycle assessment (LCA) method. The results of the work show that glass and composite packaging is worse than plastic packaging except for the impact category Resource use (mineral and metals) and Human toxicity. The best packaging appears to be plastic packaging with K3 decoration (paper), which has the smallest impacts in all evaluated impact categories. In the impact category Climate change, composite packaging and glass packaging have the greatest impact. The most affected category is Freshwater ecotoxicity. The highest impacts within this category are shown by glass packaging and subsequently composite packaging. In the impact category Ionizing radiation, the greatest impact has a glass packaging, then a composite packaging. Based on the results, it was determined that the main cause of the impacts of plastic cups is the production of PP granulate. In the case of glass packaging, it is the production of the glass itself, and in the case of composite packaging, the production of the composite packaging.
