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.

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

The COVID-19 pandemic has had a profound impact on all areas of life, including education. The education system, which was originally face-to-face, had to be replaced with online learning. Various problems arise related to the implementation of the Distance Learning or PJJ system. This system makes parents have to participate more in supervising as well as being a substitute for teachers at home in the learning process of their children. In addition, homeschooling also raises problems where students find it difficult to understand the material given by the teacher. The decrease in enthusiasm for learning becomes a problem when the PJJ system seems monotonous and boring. To support the government's program in breaking the chain of the spread of COVID-19 without reducing the effectiveness of online learning implemented by the Ministry of Education and Culture, this activity was carried out. This activity is expected to help reduce the anxiety of parents who are afraid that their children are not serious and have difficulty in learning. In addition, it is hoped that this activity will help participants to easily understand the material that has not been mastered. The methods of socialization, demonstration, and mentoring are carried out directly. The success of this activity can be seen from the assistance of the participants in solving the problems faced and the enthusiasm of the participants during the activity.

International agreements and policies on climate change urge for a drastic reduction in greenhouse gas (GHG) emissions to prevent a temperature rise above 2 °C at the end of the century. Determination of the product carbon footprint (CF), identifying carbon hotspots and examining ways for CF reduction is an essential step towards mitigation actions. Viticulture and winemaking are very important for the economy of Mediterranean regions, especially for the sustainability of rural areas. To determine the CF for wine, the Life Cycle Assessment (LCA) approach was adopted with system boundaries from vineyard to market. Input data were collected from 20 vineyards on the island of Cyprus, where the indigenous Xynisteri variety is cultivated and from an SME winery that uses the grapes to produce wine. The winery CF was 99,586 kg CO2-eq for 76,000 bottles produced (1.31 kg/0.75 L bottle). The uncertainty factor was determined to be ±50%, which was considered adequate for the methodology followed. The share of electrical energy was 46%, of packaging 18% and of the vineyard 16%. Fuel (transportation and heating), as well as waste management (solid and wastewater) contributed 10% each to the CF. There is potential for mitigation of the CF by replacing the bottles currently used by lighter ones, lowering the energy use and reusing a part of the solid waste as fertilizer. Research towards eco-innovation of viticulture/winemaking is essential for reducing the footprint of the sector to promote sustainable wine production.

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.

Nature-based conservation management (NBCMs) estates are seen as natural solutions to climate change and hence immune to harmful greenhouse gas (GHG) emissions. However, NBCMs, in their daily operations to protect and conserve biodiversity, may result in GHG emissions. These may come as a significant carbon burden. This is the first study based on a literature review to look at the carbon footprint of an entire conservation estate operation and management. South African National Parks (SANParks) aimed to contribute to national targets by reducing their fossil-fuel-generated energy consumption by 2% per year until achieving carbon neutrality. The objectives of this paper were (1) to quantify the SANParks C emissions profile at the organization and individual park level and develop recommendations to sustainably reduce carbon emissions and (2) to suggest alternative scenarios that SANParks could follow to achieve zero energy emissions. The study presented an audit analysis of the emission sources linked to SANParks’ daily activities over a five-year period (2015–2019) using the GHGs protocol corporate accounting and reporting standard methodology. Over the reference period, SANParks emitted an average of 73,732 t of carbon dioxide equivalent (tCO2e) per year. Most emissions came from electricity usage, 40,681 tCO2e (55%), followed by fuel usage for stationary combustion at 26,088 tCO2e (35%), and both account for 90% of SANParks’ total emissions. Results have shown the variation amongst individual parks in GHG emission and intensity ratio among the different parks. Total SANParks emission showed a significant relationship with Scope 2, followed by number of employees, building size, Scope 3, and Scope 1, in order. This work recommends how SANParks estate may reduce their carbon emissions at a national and individual level. SANParks achieved 1% year-on-year energy emissions reduction through its renewable base; however, an ambitious target of 8% would be appropriate for a 1.5 °C future based on the energy scenario planning.

Cities account for 70% of carbon emissions and are therefore a vital driver for climate change. Thus, a city’s main contributing sectors need to be identified. Territorial-based footprints focus on the final energy consumption, which is derived from the stationary and transport sectors. The consumption-based approach is based on consumption data, which are converted into carbon emissions using an input–output model. If the consumption-based approach is applied to an urban district not only emissions in the investigated area are considered, but also those that occur along the supply chain of consumed products in the urban district. The goal of this study was to apply and evaluate two different approaches to calculate an urban district’s carbon footprint to support climate protection management at the local government level. To achieve this goal, these two different approaches were applied to calculate the carbon emissions of the urban district Wedding in Berlin and were compared regarding criteria such as data availability and relevance. The footprints resulted in 400,947 t CO2–eq. for the territorial approach and in 401,371 t CO2–eq. per year for the consumption-based approach, which resulted in 4.61 t CO2–eq and 4.62 t CO2–eq per capita and year, respectively. Methodologically, the two approaches differ significantly, but the total results showed a difference of only 0.1%. Thus, this study cannot verify that the consumption-based approach mostly leads to higher emissions per capita in the Global North. This could be due to lower purchasing power and a higher share of multiple-person households in the relatively poor urban district of Wedding, Berlin. The territorial approach is more suitable to derive measures for local climate action, whereas the consumption-based approach highlights the responsibility of consumers for GHG emissions along the supply chain and the importance of the food sector.

As a contribution to the fight against climate change, ESNE’s 2018/19 carbon footprint has been evaluated using the CarbonFeel methodology, based on ISO 14069 standards. In the scenario studied, greenhouse gas (GHG) emissions produced by direct and indirect emissions have been included. For comparative purposes, a second scenario has been analyzed in which fossil fuels used for heating are replaced by electrical energy from renewable sources. A decrease of 28% in GHG emissions has been verified, which could even reach 40% if the energy for thermal conditioning was replaced by renewables.

Home study led to a disintegration of the covid-19 spreading chain. In applying home learning systems, parents play a vital role in the student learning process during the current long-range learning system. So with home learning, it is the parents who become educators at home in place of teachers. This research aims to identify what can be problematic for parents in educating children during the covid-19 pandemic. The study involves a qualitative method that offers research interviews, observation and documentation. Among the problems of parents in educating children in the time of the covid-19, children are often in a changed mood, children are less disciplined, children are bored at home, parents need additional quotas to develop the activities of BDR, of course there is much work to be done in developing good communication to develop a good mood for children especially to carry out remote lessons, Guiding and providing motivation for children to be more disciplined, educating children, varying and innovative indoor activities so that they do not get bored quickly.

If one has a passion for the planet, then this is the right time to drastically lower the carbon emissions. A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Some carbon emissions will probably never be eradicated entirely from certain industries, such as air travel or construction. When emissions cannot be further reduced, carbon offsetting is the next best thing, says Winters (1). Offsetting emissions is paying for or investing in organisations that can extract carbon from the atmosphere to help others reduce their footprint. It could include investing in reforestation projects or new technologies that suck carbon out of the atmosphere and sequester it underground permanently, technologies to replace jet fuel with alternative green fuels, or switching fossil-fuel-powered facilities with hydrogen-powered facilities.    Unless the global economy meets the aims of the Paris Agreement, keeping climate change well below 2°C, the world is expected to suffer extreme weather conditions leading to mass migration and global catastrophe. The argument for global companies to reduce their greenhouse gas (GHG) emissions is clearer than it has ever been. Business operations around the world are now subject to greater climate and transition risks. Consumers are insisting for eco-friendly products and responsible corporate behaviours. Investors are increasingly embracing capital-allocation strategies that take environmental, social, and governance (ESG) issues into account. Policy makers and government organizations are exploring the potential regulation of carbon emissions. The more aggressive the targets, the better the results.   In COP26 climate summit in Glasgow held in November 2021, it was made clear that the current climate crisis has been precipitated by unsustainable lifestyles and wasteful consumption patterns mainly in the developed countries. The world needs to awaken to this reality. Globally, the building and construction sectors account for nearly 40% of global energy-related carbon dioxide emissions in constructing and operating buildings (2). Current building codes address operating energy but do not typically address the impacts of embodied carbon in building materials and products. However, more than half of all GHG emissions is related to materials management (including material extraction and manufacturing) when aggregated across industrial sectors (3).   In order to reduce our carbon footprint, we can start an eco-friendlier life. In winter, instead of heating, insulate the loft and walls which will make sure our home retains heat during the winter and stays cool in summer. By switching to a company that provides electricity from solar, wind, or hydroelectric energy, we can reduce our household emissions. Buy energy efficient electrical appliances. Additionally, make sure to turn off and unplug anything we are not using. It takes energy and resources to process and deliver water to our homes. So, by using less water, we can help the environment and lower our carbon footprint. The food we eat can have a significant impact on the environment. For example, meat and dairy products require a lot of land, water and energy to produce. They also create a lot of methane, a greenhouse gas. Moreover, food shipped from overseas uses a lot more resources than local produce. By eating fewer animal products, especially red meat, (or choosing a plant-based diet) and shopping for locally sourced food, we can make a big difference.  Why not support our local farmers’ market?   Powering empty rooms and office space is a huge energy drain. By making sure we turn off lights and appliances when they are not in use, we can make sure we are not wasting power. we can also request to install automatic, movement-sensing lights and energy-saving LED bulbs to address the issue. It has never been easier to collaborate with others online. Whether through sharing documents using cloud storage or video conferencing instead of travelling, we can reduce our waste and emissions. Try moving away from printed documents where possible, and encourage others to work on their digital skills for the workplace. Cycling and walking are two of the most environmentally friendly ways to travel. And, not only are they good for the planet, but they are also good for our health. If we can, choose to cycle or walk to work where possible. ‘Reduce, reuse, recycle’ is a popular slogan. Companies of all sizes use a host of different products in their day-to-day running. Whether it has things like paper, electronic devices, packaging, or water, it all has a carbon footprint. By reducing the amount of waste, we generate, reusing IT equipment, and recycling waste, we can make a real difference. Single use plastics may be convenient, yet they are fairly dreadful for the environment. Not only do they pollute our waterways and oceans, but they also require energy to produce and recycle. We can stop using things like disposable coffee cups and cutlery to reduce our company’s carbon footprint. Instead of preaching, let us practise and bring a change.
