“…Furthermore,Hristov et al (2011) indicated that NH 3 emission factors from large ruminant production systems are highly variable with dairy farms. Data gaps for some NH 3 emission factors were claimed byCederberg et al (2013), who included the improving of models for N fluxes and emissions from soil in the top priorities of LCA research.Regarding background information, Ecoinvent is the most widely used data set (cited in 18 of the selected papers), but other databases were also employed. BUWAL, IDEMAT, Franklin, and CCalc are different databases encountered in the selected studies.…”

“…Emissions from land use change (LUC) are presented separately in a sensitivity analysis due to lack of agreed methodology and since the choice of calculation method strongly influences ration CF (Flysjö et al, 2012). Nor were CO 2 lost from or C sequestered in soil included due to methodological difficulties and large uncertainties in estimating them since the process is reversal and largely influenced by initial soil organic carbon stocks (which vary widely) and climate regimes (Kätterer et al, 2012;Cederberg et al, 2013).…”

Feed production is a significant source of greenhouse gas (GHG) emissions from dairy production and demands large arable and pasture acreage. This study analysed how regional conditions influence GHG emissions of dairy feed rations in a life cycle perspective, that is the carbon footprint (CF) and the land area required. Factors assessed included regional climate variations, grass/clover silage nutrient quality, feedstuff availability, crop yield and feed losses. Using the Nordic feed evaluation model NorFor, rations were optimised for different phases of lactation, dry and growing periods for older cows, first calvers and heifers by regional feed advisors and combined to annual herd rations. Feed production data at farm level were based on national statistics and studies. CF estimates followed standards for life cycle assessment and used emissions factors provided by IPCC. The functional unit was ' feed consumption to produce 1 kg energy corrected milk (ECM) from a cow with annual milk yield of 9 900 kg ECM including replacement animals and feed losses'. Feed ration CF varied from 417 to 531 g CO 2 e/kg ECM. Grass/clover silage contributed more than 50% of total GHG emissions. Use of higher quality silage increased ration CF by up to 5% as a result of an additional cut and increased rates of synthetic N-fertiliser. Domestically produced horse bean ( Vicia faba), by-products from the sugar industry and maize silage were included in the rations with the lowest CF, but horse bean significantly increased ration land requirement. Rations required between 1.4 to 2 m 2 cropland and 0.1 to 0.2 m 2 /kg semi-natural grassland per kg ECM and year. Higher yield levels reduced ration total CF. Inclusion of GHG emissions from land use change associated with Brazilian soya feed significantly increased ration CF. Ration CF and land use depended on ration composition, which was highly influenced by the regional availability and production of feedstuffs. The impact of individual feedstuffs on ration CF varies due to, for example, cultivation practices and climate conditions and feedstuffs should therefore be assessed in a ration and regional perspective before being used to decrease milk CF. Land use efficiency should be considered together with ration CF, as these can generate goal conflicts.

“…Therefore, CF is expressed in carbon dioxide equivalent (CO 2 eq.) [26], measuring the total greenhouse gas emissions directly caused by individual, activity, organization or product [27]. So it is necessary to analyze the CF, since it is one of the highlights of all concerns related to environmental issues, of representative dangerous chemicals' packages.…”

Abstract:The purpose of this paper was to analyze the development trend of hazardous chemical packaging towards low carbon economy from both qualitative and quantitative perspectives. Four types of relatively small volume packaging with volume/weight less than 450L/400kg, respectively, and three intermediate bulk containers (IBCs), which are widely used for hazardous chemicals were studied to calculate the carbon footprint (CF) from cradle to grave using life cycle assessment (LCA) method and to predict the future carbon emission of hazardous chemical packaging in the next five years (2016)(2017)(2018)(2019)(2020), based on the export data of Tianjin Port in China. Grey model (GM) was adopted in the prediction. The results showed that majority of IBCs have lower carbon footprint than other types when the packaging contained same amount of same hazardous chemical. With the development of international trading, the demand of hazardous chemicals will increase as well. As the result, carbon emission generated by hazardous chemical packaging will increase accordingly. However, based on GM simulation result, increasing the amount of IBC use will effectively reduce the relative amount of carbon emission.
