With more and more governments and organizations taking Carbon Footprint as the measure of greenhouse gas emission, the study about the calculation of carbon footprint has become a hot spot. The paper analyzed the carbon footprint in different stages of a product life circle, including manufacturing, transporting, using and disposing and also studied the part contributing the largest carbon emission. Especially in the calculation of carbon emission of manufacturing stage, recursive call algorithm was applied. The optimization design model of carbon footprint was also depicted. All the work this paper had undertaken facilitates to formulate specific carbon emission reduction measures.

<p>Carbon footprint (CF) is a measure of greenhouse gas emissions generated from daily human-induced activities as carbon dioxide equivalent. This study is an attempt to represent a consumption-based CF study from the scope of transportation, electricity, and waste generation for University of the Punjab (PU), Lahore under the WRI/WBCSD greenhouse gas protocol corporate standards. Data acquired through fieldwork, questionnaire surveys, direct sampling, and existing records for the year 2019-20 suggested that electricity is the greatest contributor of CO2 emissions at 59%, followed by transportation at 36%, and waste generation at approximately 5%. The total CF(CO2_eq) generated from different sources is about 18360.62MT for one year. The recent COVID-19 lockdown has offered inimitable prospect to compare the carbon footprint of one of the largest higher education institutes of Pakistan before and during this pandemic. The data can serve for tracking, assessing, and setting goals for greenhouse gas emission reduction programs in future.</p>

This study aimed to analyze the holistic amount of greenhouse gas emission of Napier Pakchong 1 grass plantation in Prachinburi Province, Thailand, in a term of carbon footprint. The carbon footprint of Napier plantation from irrigation plot and non-irrigation plot was 17.182 and 19.138 kg CO2e/ton of Napier Pakchong 1 grass, respectively. The largest contribution to the greenhouse gas emission came from the fertilizer application. The irrigation to the crop significantly increased the crop yield resulting in the reduction of greenhouse gas emission per unit weight of the crop. The suitable type and the optimal quantity of fertilizer application, as well as the most efficient irrigation system with the least environmental impact, were suggested for further study.

A field experiment was conducted at research farm, Bihar Agricultural University, Sabour, India during 2017 and 2018 to gain insight crop phonology mediated greenhouse gas emission under different tillage and nitrogen management practices in direct seeded rice (DSR). The experiment was conducted in split plot design with two tillage viz. zero tillage (ZT) and conventional tillage (CT) as main plot and four nitrogen management practices viz. 100% nitrogen through neem coated urea (S1), SPAD based nitrogen management (S2), 75% through neem coated urea + 25% nitrogen through vermicompost, (S3) and ¼ nitrogen as basal and rest in equal three splits at 20, 40, 60 DAS (S4) as sub plot, in three replication. The highest yield (4.69 t ha-1), net return (Rs 46440 ha-1) and B:C ratio (1.44) were recorded from zero tilled DSR. Further, highest yield (4.82 t ha-1), net return (Rs 44880 ha-1) and B:C ratio (1.36) was obtained under split application of nitrogenous fertilizers among other subplot treatments. The range of methane (0.57- 1.47 mg m-2 hr-1) carbon dioxide (0.32- 0.61 mg m-2 hr-1)  and nitrous oxide (19.58- 38.79 µg m-2 hr-1) emission was recorded lowest in zero tilled plots and split application of nitrogenous fertilizer also emitted lowest values of 1.59 mg m-2 hr-1 methane, 0.86 mg m-2 hr-1 carbon dioxide and 46.76 µg m-2 hr-1 nitrous oxide at maximum tillering stage of crop growth. Moreover, methane and nitrous oxide emission was gradually decreased from maximum tillering to harvesting stage. Zero tilled DSR with split nitrogen fertilizer application ascribed lowest greenhouse gas intensity among the other crop establishment and nitrogen management options. Thus, zero tilled method of crop establishment with split application of nitrogenous fertilizer could be a remunerative and environmentally stable method for direct seeded rice cultivation.
