Every individual or agency activity will generate greenhouse gas emissions which could be countable and expressed as equivalent to carbon dioxide. One of the activities that produce carbon emissions is activities carried out on the campus, one of which is  Batanghari University. Batanghari University consists of 5 faculties, namely the Faculty of Teacher Training and Science, Faculty of Law, Faculty of Economics, Faculty of Engineering and Faculty of Agriculture with a total population of Batanghari University of 5,582 people including 5,278 students, 210 lecturers and 94 education staff. This study aims to analyze the amount of carbon emissions generated from activities of the Batanghari University and to compare the percentage of total carbon emissions produced from each scope. Calculation of carbon emissions using the method of The Greenhouse Gas Protocol (GHG Protocol), by dividing it into 3 scopes, including calculating the carbon footprint from transportation activities, emission form the used of gas, and emissions from electricity used and the used of paper. Carbon dioxide (CO2) emissions calculated by using the IPCC (International Panel On Climate Change) method. The results showed that the total carbon footprint produced at the Batanghari University for 6 months was 790.24 ton.CO2-eq. The distribution of emissions based on the scope as follows : scope 1 activity of electricity consumption was 162,705 ton.CO2-eq; scope 2 activities of using LPG was 0.609 ton.CO2-eq; and the scope 3 transportation activities of lecturers, students and education staff was 625.91 ton.CO2 -eq and paper usage activity are 1.0247 ton.CO2-eq. The largest carbon footprint was generated from transportation activities at 79.2% and the smallest was the use of LPG at 0.07%.

Abstract. The electricity consumption for commercial, residential, and industrial sectors is considered the primary cause of increasing carbon dioxide emissions. To calculate the carbon footprint, the researcher used Carbon Footprint Ltd. This study aims to quantify the carbon footprint associated with the consumption of electricity by sectors (residential, commercial, industrial, public buildings, and streetlights) in Butuan City during the pre-lockdown period (January and February), and then compare these with the carbon footprint calculated during the lockdown period (March and April 2020). A GIS-based approach was applied to generate the spatial distribution across the 86 barangays of Butuan City. The study findings that the carbon footprint in the lockdown period is ∼ −17% lower than the mean carbon footprint calculated for the pre-lockdown period. In absolute values, the total estimated carbon footprint during the pre-lockdown and lockdown period was ∼ 10,947 mtCo2e and ∼ 9,138 mtCo2e, respectively. Furthermore, the findings imply that the central and northern areas have the highest impact of savings on average ∼ 130 mtCo2e of greenhouse gas avoided by barangays. This research provides quantitative insight to understand the measured generated in lockdown and pre-lockdown periods.

This article explores the issues of carbon dioxide (CO2) emissions resulting from the production of the goods and services provided to supply tourism consumption. First, we define the scope of tourism activities and the resulting tourism consumption and tourism direct gross value added (TDGVA). Second, we calculate CO2 emissions for sectors and compile a carbon input-output table (CIOT). Third, we adjust the tourism-related products consumed according to the range of the corresponding sectors of the CIOT. Finally, we use Shanghai as an example to calculate the carbon emissions that result from tourism consumption using the input-output model. This study shows that the TDGVA accounted for 7.97% of the Gross Domestic Product (GDP) in 2012, whereas the carbon footprint of tourism accounted for 20.45% of total carbon emissions. The results demonstrate that tourism is not a low-carbon industry in Shanghai.

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.

The article provides an overview and analysis of the state of the problem of reducing greenhouse gas (GHG) emissions in Russia, considers the measures developed at the level of the country and individual corporations that issue GHG to combat climate change. Particular attention is paid to methods of carbon dioxide (CO2) compensation, including taking into account the absorbing capacity of forests. The experience of the largest Russian oil company "Tatneft" is described in the implementation of a project for the breeding and scaling of triploid aspen with an increased absorptive capacity for planting seedlings in forests in order to reduce and compensate for the carbon footprint.

Abstract. In recent years, space-borne observations of atmospheric carbon-dioxide (CO2) have become increasingly used in global carbon-cycle studies. In order to obtain added value from space-borne measurements, they have to suffice stringent accuracy and precision requirements, with the latter being less crucial as it can be reduced by just enhanced sample size. Validation of CO2 column averaged dry air mole fractions (XCO2) heavily relies on measurements of the Total Carbon Column Observing Network TCCON. Owing to the sparseness of the network and the requirements imposed on space-based measurements, independent additional validation is highly valuable. Here, we use observations from the HIAPER Pole-to-Pole Observations (HIPPO) flights from January 2009 through September 2011 to validate CO2 measurements from satellites (GOSAT, TES, AIRS) and atmospheric inversion models (CarbonTracker CT2013B, MACC v13r1). We find that the atmospheric models capture the XCO2 variability observed in HIPPO flights very well, with correlation coefficients (r2) of 0.93 and 0.95 for CT2013B and MACC, respectively. Some larger discrepancies can be observed in profile comparisons at higher latitudes, esp. at 300 hPa during the peaks of either carbon uptake or release. These deviations can be up to 4 ppm and hint at misrepresentation of vertical transport. Comparisons with the GOSAT satellite are of comparable quality, with an r2 of 0.85, a mean bias μ of −0.06 ppm and a standard deviation σ of 0.45 ppm. TES exhibits an r2 of 0.75, μ of 0.34 ppm and σ of 1.13 ppm. For AIRS, we find an r2 of 0.37, μ of 1.11 ppm and σ of 1.46 ppm, with latitude-dependent biases. For these comparisons at least 6, 20 and 50 atmospheric soundings have been averaged for GOSAT, TES and AIRS, respectively. Overall, we find that GOSAT soundings over the remote pacific ocean mostly meet the stringent accuracy requirements of about 0.5 ppm for space-based CO2 observations.

Cheap meat, dairy, and eggs are an illusion—we pay for each with depleted forests, polluted freshwater, soil degradation, and climate change. Diet is the most critical decision we make with regard to our environmental footprint—and what we eat is a choice that most of us make every day, several times a day. Dietary choice contributes powerfully to greenhouse gas emissions (GHGE) and water pollution. Animal agriculture is responsible for an unnerving quantity of greenhouse gas emissions. Eating animal products—yogurt, ice cream, bacon, chicken salad, beef stroganoff, or cheese omelets—greatly increases an individual’s contribution to carbon dioxide, methane, and nitrous oxide emissions. Collectively, dietary choice contributes to a classic “tragedy of the commons.” Much of the atmosphere’s carbon dioxide (CO2) is absorbed by the earth’s oceans and plants, but a large proportion lingers in the atmosphere—unable to be absorbed by plants or oceans (“Effects”). Plants are not harmed by this process, but the current overabundance of carbon dioxide in the atmosphere causes acidification of the earth’s oceans. As a result of anthropogenic carbon dioxide emissions, the “acidity of the world’s ocean may increase by around 170% by the end of the century,” altering ocean ecosystems, and likely creating an ocean environment that is inhospitable for many life forms (“Expert Assessment”). Burning petroleum also leads to wars that devastate human communities and annihilate landscapes and wildlife—including endangered species and their vital habitats. Additionally, our consumption of petroleum is linked with oil spills that ravage landscapes, shorelines, and ocean habitat. Oil pipelines run through remote, fragile areas—every oil tanker represents not just the possibility but the probability of an oil spill. As reserves diminish, our quest for fossil fuels is increasingly environmentally devastating: Canada’s vast reserves of tar sands oil—though extracted, transported, and burned only with enormous costs to the environment—are next in line for extraction. Consuming animal products creates ten times more fossil fuel emission per calorie than does consuming plant foods directly (Oppenlander 18). (This is the most remarkable given that plant foods are not generally as calorically dense as animal foods.) Ranching is the greatest GHGE offender.

The production of primary aluminum is an energy-intensive industry which produces large amounts of direct and indirect greenhouse gas emissions, especially from electricity consumption. Carbon Emissions Constrained Energy Planning proved to be an efficient tool for reducing energy-related greenhouse gas emissions. This study focuses on energy planning constrained by CO2 emissions and determines the required amount of CO2 emissions from electricity sources in order to meet specified CO2 emission benchmark. The study is demonstrated on and applied to specific aluminum products, aluminum slugs and aluminum evaporator panels. Three different approaches of energy planning are considered: (i) an insight-based, graphical targeting approach, (ii) an algebraic targeting approach of cascade analysis, and (iii) an optimization-based approach, using a transportation model. The results of the three approaches show that approximately 2.15 MWh of fossil energy source should be replaced with a zero-carbon or 2.22 MWh with a low-carbon energy source to satisfy the benchmark of CO2 emissions to produce 1 t of aluminum slug; however, this substitution results in higher costs. This study is the first of its kind demonstrated on and applied to specific aluminum products, and represents a step forward in the development of more sustainable practices in this field.

Abstract In the present work the carbon footprint for a material developed in the Faculty of Architecture, Design and Urbanism of the Autonomous University of Tamaulipas (UAT) constituted by argillaceous earth, aloe juice and fiber of ixtle with utility like the inner coating of walls in buildings was determined. The objective of this paper is the calculation of the contribution of carbon dioxide (CO2) by the plant, considering the stoichiometry of CO2 absorption accompanied by the determination at the laboratory level. It was found that the use of organic materials in mortar mixtures, when they are produced manually by the person who will use them, and that is common in cases of self-construction, can generate approximately −0.45 kg of CO2 equivalent for each kilogram of plant produced for the preparation of mixtures. In addition, the equivalent CO2 was calculated for the elaboration of a cubic meter of useful mixture as a wall covering obtaining a value below the equivalent 14 kg of CO2.

As a Party to the United Nations Framework Convention on Climate Change (UNFCCC), and its Kyoto Protocol, Romania is required to elaborate, regularly update and submit the national GHG Inventory. In compliance with the reporting requirements, Romania submitted in 2010 its ninth version of the National Inventory Report (NIR) covering the national inventories of GHG emissions/removals for the period 1989-2008. The inventories cover all sectors: Energy, Industrial Processes, Solvent and other product use, Agriculture, LULUCF and Waste. The direct GHGs included in the national inventory are: Carbon dioxide (CO2); Methane (CH4); Nitrous oxide (N2O); Hydrofluorocarbons (HFCs); Perfluorocarbons (PFCs); Sulphur hexafluoride (SF6). The emissions trend over the 1989-2008 period reflects the changes characterized by a process of transition to a market economy. With the entire economy in transition, some energy intensive industries reduced their activities and this is reflected in the GHG emissions reduction. Energy represents the most important sector in Romania, accounting for about 69% of the total national GHG emissions in 2008. The most significant anthropogenic greenhouse gas is the carbon dioxide. The decrease of CO2 emissions is caused by the decline of the amount of fossil fuels burnt in the energy sector, as a consequence of activity decline. According to the figures, there is a great probability for Romania to meet the Kyoto Protocol commitments on the limitation of the GHG emissions in the 2008-2012 commitment period.
