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 Funding Acknowledgements Type of funding sources: Other. Main funding source(s): Special Research Fund (BOF), Hasselt University Introduction The transportation sector is one of the major sectors influencing climate change, contributing around 16% of total Greenhouse gases (GHG) emissions. Aviation contributes to 12% of the transport related emissions. Among other climate change impacts, elevated heat exposure is associated with increased cardiac events and exposure to air pollution caused by GHG emissions has also well-known association with increased cardiovascular related morbidity and mortality. The global temperature rise should be restricted to less than 2 °C which requires keeping carbon emission (CO2) less than 2900 billion tonnes by the end of the 21st century. Assuming air travel a major contributing source to GHG, this study aims to raise the awareness about potential carbon emissions reduction due to air travel of international events like a scientific conference. Purpose Due to the global pandemic of COVID-19, the Preventive cardiology conference 2020 which was planned to be held at Malaga Spain, instead was held in virtual online way. This study aims to calculate the contribution of reduced CO2  emissions in tons due to ESC preventive cardiology conference 2020, which was then held online and air travel of the registered participants was avoided. Methods Anonymized participant registration information was used to determine the country and city of the 949 registered participants of the Preventive Cardiology conference 2020. It is assumed that participants would have travelled from the closest airports from their reported city locations to Malaga airport, Spain. At first, the closest city airports were determined using Google maps and flights information, then the flight emissions (direct and indirect CO2-equivalent emissions) per passenger for the given flight distances were calculated. The CO2 emissions (tons) were calculated for round trips in economy class from the participants of 68 nationalities (excluding 60 participants from Spain as they are assumed to take other modes of transport than airplane). Results In total, 1156.51 tons of CO2  emissions were saved by turning the physical conference into a virtual event. This emission amount is equivalent to the annual CO2 production of 108 people living in high-income countries. Conclusion The pandemic situation has forced us to rethink the necessity of trips by air and has shown us the feasibility of digitally organized events. The information from this study can add to the awareness about reduced amount of carbon emission due to air travel by organizing events in a virtual way when possible. Apart from only digitally organized events there are others options to reduce the carbon footprint of conferences such as limiting the number of physical attendees, encouraging the use of relatively sustainable transport modes for participants from nearby countries (e.g. international trains and use of active transport modes at conference venue etc.) and including CO2 emission offsetting costs.

The Circular Economy concept implies the re-design of existing production systems in agriculture, by promoting agricultural waste recycling. In an organic zucchini—lettuce rotation, two different agroecological tools were considered: biofertilizer and presence or absence of green manure (GM+ and GM−). In particular, we compared: (i) anaerobic digestate from cattle manure, co-composted with vegetable wastes, with the presence of GM (AD GM+); (ii) olive pomace compost, re-composted, with the presence of GM (OWC GM+); (iii) municipal waste compost with GM (MWC GM+); (iv) municipal waste compost without GM (MWC GM−). These materials were tested with a commercial organic fertilizer without GM (COF GM−) as a positive control. The objectives were: (i) assessing the environmental sustainability of biofertilizers through carbon footprint analysis by greenhouse gas—GHG—emissions; (ii) evaluating the agronomic performance on the vegetable rotation, by energy output assessment. The total carbon emissions of biofertilizers production was 63.9 and 67.0 kg of CO2 eq Mg−1 for AD and OWC, respectively. The co-composting and re-composting processes emitted 31.4 and 8.4 kg CO2 per Mg of compost, respectively. In AD the ventilation phase of composting accounted for 37.2% of total emissions. The total CO2 emission values for the two-crop cycles were the highest in COF GM− and the lowest in OWC GM+, due to different fertilizer sources. On the average of the treatments, the input that induced the highest CO2 emission was irrigation (37.9%). The energy output assessment for zucchini and lettuce highlighted similar performance for all the treatments. Our findings demonstrated the validity of the tested processes to recycle agro-industrial wastes, and the potential of agroecological practices (GM) to mitigate GHG emissions.

This paper presents a review of carbon dioxide (CO2) emissions from transportation in an attempt to establish a quick and suboptimal update of the methods used to calculate and analyze CO2 emissions from transportation. Transportation is the largest contributor to air pollution through the release of high amounts of CO2 gas into the atmosphere. The methods for calculating and analyzing the carbon footprint of transportation; which is of critical importance in the management of greenhouse gases that contribute to global warming; are still being developed. However; there are some differences in the definitions and methods used to calculate the carbon footprint of transportation in previous studies. This review focuses on the similarities of the methods used to measure CO2 emissions as well as the analyses used to evaluate the emissions. This paper will also highlight the advantages and limitations of each research work. By doing this; the present study contributes to the selection of appropriate methods for calculating CO2 emissions from transportation and draws attention to environmental issues. It is hoped that the implementation of the most appropriate framework will help to reduce CO2 emissions from transportation

Abstract. Reservoirs are important sources of greenhouse gases (GHGs) to the atmosphere, and their number is rapidly increasing, especially in tropical regions. Accurately predicting their current and future emissions is essential but hindered by fragmented data on the subject, which often fail to include all emission pathways (surface diffusion, ebullition, degassing, and downstream emissions) and the high spatial and temporal flux variability. Here we conducted a comprehensive sampling of Batang Ai reservoir (Malaysia), and compared field-based versus modelled estimates of its annual carbon footprint for each emission pathway. Carbon dioxide (CO2) and methane (CH4) surface diffusion were higher in upstream reaches. Reducing spatial and temporal sampling resolution resulted in up to a 64 % and 33 % change in the flux estimate, respectively. Most GHGs present in discharged water were degassed at the turbines, and the remainder were gradually emitted along the outflow river, leaving time for CH4 to be partly oxidized to CO2. Overall, the reservoir emitted 2475 gCO2eqm-2yr-1, with 89 % occurring downstream of the dam, mostly in the form of CH4. These emissions, largely underestimated by predictions, are mitigated by CH4 oxidation upstream and downstream of the dam but could have been drastically reduced by slightly raising the water intake elevation depth. CO2 surface diffusion and CH4 ebullition were lower than predicted, whereas modelled CH4 surface diffusion was accurate. Investigating latter discrepancies, we conclude that exploring morphometry, soil type, and stratification patterns as predictors can improve modelling of reservoir GHG emissions at local and global scales.

Abstract Green Open Space (GOS) is one of the efforts to deal with increasing greenhouse gas (GHG) emissions because it can absorb CO2 emissions. Transportation activities cause high CO2 emissions, and the lack of public green open space, which results in the ability of green open space to absorb emissions, is not optimal. The intensity of traffic activity is getting more and more crowded, which will impact the surrounding community. This study aims to determine the level of adequacy of public green open space (GOS) in absorbing carbon dioxide (CO2) emissions from transportation activities. This study uses a literature review approach. The results obtained are the adequacy of public green open space in absorbing emissions from transportation and so that solutions are obtained to carry out policies in reducing air pollution produced by vehicles, and the importance of green open spaces (GOS).

The objective of this study is to compare the carbon dioxide (CO2) emissions from materials used in the execution of internal building masonry for construction projects that use plaster blocks and those using ceramic bricks. A total of 20 projects in the city of Recife, Brazil, were analyzed, all of them belonging to a large construction company operating in the Northeast region. The Greenhouse Gas (GHG) emissions were estimated using indexes found in the literature and calculated based on the Energy Life Cycle Assessment (ELCA). The emissions from the transport of materials to the construction site were calculated based on the driving distances between the suppliers and the building sites, taking into account the fuel consumption of the transport vehicles. The construction sites using plaster blocks for the internal masonry seals obtained an average indicator of 19.21 kgCO2/m² of constructed area compared to 33.86 kgCO2/m² from those using ceramic bricks. Construction sites using plaster blocks for internal masonry had a 43.26% reduction in GHG emissions and there was a strong correlation between costs due to the execution of activities and material emissions.

Plans for mitigating greenhouse gas (GHG) emissions in the agri-food sector should not only include the production of agricultural raw materials but also the food processing industry. The aim of the research was to determine the carbon footprint of a meat processing enterprise and to analyze the intensity indicators of GHG emissions. The study was conducted in a medium-sized company, located in the Wielkopolska Province, for which pork is a basic feedstock for the production (over 81.0%). The results show that the largest GHG emissions were related to the consumption of electricity, natural gas and fuels in the transport of products. There were estimated values of several indicators of emission intensity. The main indicator of GHG emissions related to the unit of product was 519 g CO2 eq. per 1 kg. It is concluded that the analysis of the carbon footprint can be an important instrument for the management of GHG emissions at the company level and can also serve the purpose of assessing the effects of implementing plans for a low-carbon economy in the meat processing sector.

Emisi karbon Gas Rumah Kaca (GRK) yang dihasilkan dalam penyelenggaraan pendidikan di Perguruan Tinggi dapat dikatakan cukup tinggi. Akumulasi karbon menjadi penyebab efek rumah kaca yang berdampak pada peningkatan suhu bumi atau disebut pemanasan global dan menimbulkan bencana ekologis. Pandemi Covid 19 telah memaksa proses belajar di rumah, secara otomatis hal tersebut mendorong adanya jeda dalam penggunaan energi dari alat elektronik dan kendaraan bermotor yang juga berarti terjadi penurunan Emisi GRK dari energi tersebut. Tujuan penelitian ini adalah untuk mengetahui besaran jejak karbon yang dihasilkan selama proses pembelajaran di kampus, sekaligus potensi penurunan Emisi karbon oleh belajar dari rumah. Metode penelitian adalah kuantitatif melalui pendekatan berbasis analisis jejak karbon sebagai instrumen untuk menghitung jumlah karbondioksida (CO2) dari kegiatan manusia. Selanjutnya dilakukan konversi nilai energi listrik (KWh) dan bahan bakar minyak (Liter/jam) menjadi besaran carbon GRK yang dihasilkan (CO2 α) dari kegiatan belajar/perkuliahan secara tatap muka dalam kelas. Hasil penelitian menunjukkan besaran jejak karbon yang diperoleh dari kuliah tatap muka, kemudian diturunkan melalui belajar di rumah sebesar 749.868 Kg untuk simulasi 100 kelas/tahun. Diharapkan pengurangan Emisi GRK melalui pembelajaran di rumah ini dapat menjadi satu habituasi baru pasca wabah Covid 19. Kata kunci: Belajar di rumah, jejak karbon, gas rumah kaca. ABSTRACT  Greenhouse Gas (GHG) carbon emissions generated in the implementation of education in Higher Education can be said to be quite high. The accumulation of carbon causes the greenhouse effect which has an impact on increasing the temperature of the earth or is called global warming and causing ecological disasters. The Covid 19 pandemic has forced the learning process at home, automatically this has led to a pause in the use of energy from electronic devices and motorized vehicles which also means a reduction in GHG emissions from this energy. The purpose of this study was to determine the amount of carbon footprint generated during the learning process on campus, as well as the potential for reducing carbon emissions by learning from home. The research method is quantitative through an approach based on carbon footprint analysis as an instrument to calculate the amount of carbon dioxide (CO2) from human activities. Furthermore, the value of electrical energy (KWh) and fuel oil (Liters / hour) is converted into the amount of carbon GHG produced (CO2 α) from face-to-face learning activities in class. The results showed that the amount of carbon footprint obtained from face-to-face lectures, then reduced through home study, was 749,868 kg for a simulation of 100 classes / year. It is hoped that reducing GHG emissions through learning at home can become a new habituation after the Covid 19 outbreak. Keywords: Carbon footprint, greenhouse gases, home study.
