Food and diet life cycle assessment (LCA) studies offer insights on the environmental performance and improvement potential of food systems and dietary patterns. However, the influence of ingredient resolution in food-LCAs is often overlooked. To address this, four distinct decomposition methods were used to determine ingredients for mixed dishes and characterize their environmental impacts, using the carbon footprint of the U.S. daily pizza intake as a case study. Pizza-specific and daily pizza intake carbon footprints varied substantially between decomposition methods. The carbon footprint for vegetarian pizza was 0.18–0.45 kg CO2eq/serving, for meat pizza was 0.56–0.73 kg CO2eq/serving, and for currently consumed pizzas in the U.S. (26.3 g/person/day; 75 pizzas types) was 0.072–0.098 kg CO2eq/person/day. These ranges could be explained by differences in pizza coverage, ingredient resolution, availability of ingredient environmental information, and ingredient adjustability for losses between decomposition methods. From the approaches considered, the USDA National Nutrient Database for Standard Reference, which reports standardized food recipes in relative weights, appears to offer the most appropriate and useful food decompositions for food-LCAs. The influence and limitations of sources of reference flows should be better evaluated and acknowledged in food and diet LCAs.

Life Cycle Assessment (LCA) has been increasingly used for the improvement of the environmental performance of products and services, including agro-food chains. Pollination by honeybees can be regarded as one of the functions of an apicultural system and is of utmost importance for both natural ecosystems and agriculture. Furthermore, the beekeeping chain can represent an instrument for the protection and conservation of honeybee diversity when local subspecies are used. The Carbon Footprint of honey evaluates greenhouse gas emissions throughout the Life Cycle Assessment—more specifically, emissions of carbon dioxide, nitrous oxide, and methane. To this aim, data from beekeeping farms were collected, including data on annual honey production, other hive products, the geographical locations of the apiaries, processing plants, technologies used, and fuel and energy consumption. Based on the ISO 14040 method for the use of Life Cycle Assessment, the Carbon Footprints that were calculated for honey ranged from 1.40 to 2.20 kg CO2e/kg of honey for migratory beekeeping and from 0.380 to 0.48 kg CO2e/kg of honey for non-migratory beekeeping. The movements for the management of migratory beehives (on average, 44 km/hive for farm 1, 32 km/hive for farm 2, and 13 km/hive for farm 3) represented the main impact in migratory beekeeping systems, and they were quantified as 1.234, 1.113, and 0.68 CO2e/kg of honey. However, electricity represented the main impact of systems without migratory practices.

This paper presents a life cycle assessment (LCA) of bleached eucalyptus kraft pulp production in Brazil. The entire production system was investigated, starting with forestry and ending with bleached pulp at the gate of the pulp mill. Alternative bleaching sequences were compared for three different scenarios using somewhat different elemental chlorine-free (ECF) sequences: Dhot(EPO)DD, Dhot(EPO)DP, and aZeDP. The main difference between the scenarios investigated was the magnitude of the carbon footprint contribution from bleaching. For the base case and chemical island scenarios (both reflecting Brazilian conditions), the contribution was 15%-18% of the total carbon footprint. For the ecoinvent scenario, the corresponding share was 34%-41%. The ecoinvent scenario represents generic LCA data for bleaching chemicals. Ecoinvent is a public database commonly included in commercial LCA software. For each scenario, the alternative bleaching sequences studied resulted in similar carbon footprints of the bleached pulp. A comparison of the data from the different scenarios showed a large range of carbon footprints for the chemicals used for pulp bleaching. It is crucial to select data sets that are relevant in terms of geography and technology. The most dominant contributors to the carbon footprint of the unbleached pulp were forestry and pulp production. Although the focus has been on carbon footprints, the contributions to other environmental effects commonly included in LCAs were also assessed and only minor differences between the alternative bleaching sequences were found.
