Due to manufactured technology enchantment the living being has much convenience and luxury. Though, at the same time, our current existence is doing damage to the environment. Like water pollution, air pollution and Carbon dioxide (CO2) emissions on so forth. But CO2 emissions are the one of the major reason polluting the environment. Furthermost of what we utilise in our daily life lead to emitting CO2 into the environment. Due to this it leads to global warming and climate change problems. Therefore, carbon auditing (Carbon Footprint Analysis) is the first essential step to review the use of energy, to improve energy conservation and to allow building to go green. For this reason we need carbon audit to reduce usage raw materials, waste generation so on so forth to minimise GHG emissions .“CARBON AUDIT” is conducted within the building’s boundary which includes the following stages:- People Survey to gather employee-level data, Building Survey to gather building-operation data, Carbon Footprint Analysis to evaluate the greenhouse gas (GHG) emission and Final Carbon Audit Report to provide tailored recommendations for going green along with action plan to get started

Abstract The Covid-19 pandemic is impacting entire countries. One of them is having an impact on CO2 emissions in Indonesia and Japan. The research project is focused on the use of transportation and electricity by Japanese Literature students of BINUS and Wakayama University Japan students before and during the pandemic. Concepts and methodologies, looking at the situation before and during a pandemic, using quantitative methods and approaches based on carbon footprint analysis. This study provides results showing that the use of electronics and transportation which has CO2 emissions is drastically reduced both in Indonesia and in Japan. However, Japan has higher CO2 emissions when compared to Indonesia which is influenced by certain factors, such as transportation mileage.

Dried Sludge

Cement manufacturing and the treatment of sludge are considered both energy-intensive industries and major greenhouse gas (GHG) emitters. However, there are still few studies on comprehensive carbon footprint analysis for adding municipal sludge in the cement production. In this study, the lime-dried sludge blended with calcium oxide at the mass mixing ratio of 10% was utilized as raw material for the preparation of Portland cement. The chemical and physical properties of sludge were analyzed. A set of carbon footprint calculation methods of lime-drying treatment of sludge and reuse in cement kilns was then established to explore the feasibility of coprocessing lime-dried sludge in cement kilns. The results showed lime-dried sludge containing CaO, SiO2, Al2O3, and Fe2O3 was ideal for cement production as raw material. However, the water content of lime-dried sludge should be strictly limited. The lime-drying process presented the biggest carbon emission (962.1 kg CO2-eq/t sludge), accounting for 89.0% of total emissions. In the clinker-production phase, the lime-dried sludge as raw material substitute and energy source gained carbon credit of 578.8 and 214.2 kg CO2-eq/t sludge, respectively. The sludge used for producing cement clinker could reduce carbon emissions by 38.5% to 51.7%. The addition ratio of lime and stacking time in the sludge lime-drying process could greatly affect the carbon footprint of coprocessing lime-dried sludge in cement kiln.
