The objective of green networking is to minimize greenhouse gas emissions while maintaining the same level of performance. Green networking refers to all processes used to optimize networking and inter-networking functions to make it more energy efficient. Green networking concepts can be extended to cover any method that reduces latency, save bandwidth, and/or decrease computation time, as a reduction in these factors invariably leads to power savings. These savings can directly translate into lowering greenhouse gas emissions and reduce computing's carbon footprint and its impact on the environment. Energy-awareness is critical in the networking infrastructure, especially in wireless 5G networks and beyond. Research on blockchain for 5G wireless networks is still in its infancy. But it is obvious that blockchain will significantly uplift the shape and experience of future mobile applications and services. Identifying the green networking analytics will lead to sustainable energy policy planning for the future.

Global climatic changes have a negative impact on the development of all sectors of the economy, including agriculture. However, the very production of agricultural products is one of the most important sources of greenhouse gases entering the atmosphere. Taking into account the need to reduce the “carbon footprint” in food production, a special place is occupied by the analysis of the volume of greenhouse gas emissions and the development of measures for their sequestration in agriculture. One of the main directions for reducing emissions and immobilizing greenhouse gases is the development of special techniques for their sequestration in the soil, including those used in agriculture. Adaptation of existing farming systems for this task will significantly reduce the “carbon footprint” from agricultural production, including animal husbandry. The development of carbon farming allows not only to reduce greenhouse gas emissions, but also to significantly increase the level of soil fertility, primarily by increasing the content of organic matter in them. As a result, it becomes possible, along with the production of crop production, to produce “carbon units” that are sold on local and international markets. The paper analyzes possible greenhouse gas emissions from agriculture and the potential for their sequestration in agricultural soils. The role of various elements of the farming system in solving the problem of reducing the “carbon footprint” is considered and ways of developing carbon farming in the Republic of Tatarstan are proposed

Viticulture faces two challenges regarding climate change: adapting and mitigating greenhouse gas emissions. Are these two challenges compatible? This is one of the questions to which Adviclim project (Life project, 2014–2019) provided tools and answers. The assessment of greenhouse gas emissions was implemented at the scale of the plot using a life cycle approach: calculating the carbon footprint. This approach makes it possible to take into account the emissions generated during each stage of the life cycle of a product or a service: in this case, the cultivation of one hectare of vine for one year. Carbon footprint was assessed for the 5 pilot sites of the Adviclim project: Saint-Emilion (France), Coteaux du Layon/Samur (France), Geisenheim (Germany), Cotnari (Romania) and Plompton (United Kingdom). An important work for primary data collection regarding observed practices was carried out with a sample of reresentative farms for these 5 sites, and for one to three vintages depending on the site. Beyond the question asked in the project, the calculation of these carbon footprints made it possible to (i) make winegrowers aware of the life cycle approach and the share of direct emissions generated by viticulture, (ii) acquire new references on the technical itineraries and their associated emissions, (iii) improve the adaptation of the methodology for calculating the carbon footprint to viticulture.

Abstract Objectives The climate impacts of human food systems have been well documented. Guidance to individuals to reduce their dietary carbon footprint would benefit from simple advice, but little is known about the impact of simple changes on self-selected diets. Here we examine a random sample of high-impact diets from the U.S. to test the effects of a single change in each diet on greenhouse gas emissions (GHGE) and nutritional quality. Methods Based on an extensive review of lifecycle assessment studies in the environmental sciences literature, we created a database of Food Impacts on the Environment for Linking to Diets (dataFIELD). We matched impact data from dataFIELD to the 24-hour recall dietary data in the 2005–2010 waves of the National Health and Nutrition Examination Survey (NHANES). For all adults with reliable diets (N = 16,800), we calculated their dietary carbon dioxide equivalents per 1000 kcal (kg CO2-eq 1000 kcal−1), a density measure of GHGE. A 10% random sample (N = 330) of all diets in the top quintile of this variable was selected. The single food item with the highest GHGE was identified in each of these high-impact diets and was substituted for an equal-calorie amount of a similar, but lower impact food (e.g., chicken for beef). Each of the 330 diets were then re-evaluated on total GHGE/1000 kcal and on the Healthy Eating Index, a summary measure of nutritional quality developed for the U.S. population. Results The food with the highest impact in each of the randomly chosen diets was most often a type of beef (52%), a mixed dish with beef (33%), or a shellfish/shellfish mixed dish (10%). After single-item substitutions were made for these foods with equivalent poultry-based items, the mean impact from this sample of diets dropped (p < .001) from 4.35 ± 0.1 to 1.95 ± 0.8 kg CO2-eq 1000 kcal−1. This represents a 54% reduction in average dietary greenhouse gas emissions from diets. Healthy Eating Index values for the revised diets showed slight improvements. Conclusions Simple substitutions can be made in individuals' diets to reduce their carbon footprints, without sacrificing dietary quality. If promoted on a wide-scale basis, such a strategy could substantially reduce greenhouse gas emissions from the U.S. diet. Funding Sources Wellcome Trust.

Reduction of greenhouse gas emissions is one of the key requirements for sustainable production and consumption, but while the Canadian chemical industry has been very successful in reducing emissions to water and air, and while non- CO2 greenhouse gas emissions have been minimised as well, reduction of CO2 emissions has been less successful. The industry itself forecasts that further reduction of CO2 emissions will be minimal. On the other hand concerns about global warming are increasing, while at the same time the chemical industry increases its commitment to sustainability. Determining the carbon footprint of a chemical plant and of its products will help to identify more emissions reduction possibilities and is a necessary step for the further reduction of the chemical industry's environmental impact. Carbon footprint determination is a corporate goal for AkzoNobel, an international coatings and specialty chemicals company, but the carbon footprint is not yet established for many products, and the information available from the chemical industry is scarce. This paper presents a case study of AkzoNobel's Saskatoon Plant and its attempt to calculate and analyse the carbon footprint of the plant and its main products which are used in the potash industry.

AbstractThe livestock industry is one of the main contributors to greenhouse gas emissions and there is an increasing demand for the industry to reduce its carbon footprint. Several studies have shown that feed additives 3-nitroxypropanol and nitrate to be effective in reducing enteric methane emissions. The objective of this study was to estimate the net mitigating effect of using 3-nitroxypropanol and nitrate on total greenhouse gas emissions in California dairy industry. A life cycle assessment approach was used to conduct a cradle-to-farm gate environmental impact analysis based on dairy production system in California. Emissions associated with crop production, feed additive production, enteric methane, farm management, and manure storage were calculated and expressed as kg CO2 equivalents (CO2e) per kg of energy corrected milk. The total greenhouse gas emissions from baseline, two 3-nitroxypropanol and three nitrate scenarios were 1.12, 0.993, 0.991, 1.08, 1.07, and 1.09 kg CO2e/kg energy corrected milk. The average net reduction rates for 3-nitroxypropanol and nitrate were 11.7% and 3.95%, respectively. In both cases, using the feed additives on the whole herd slightly improved overall carbon footprint reduction compared to limiting its use during lactation phase. Although both 3-nitroxypropanol and nitrate had effects on decreasing the total greenhouse gas emission, the former was much more effective with no known safety issues in reducing the carbon footprint of dairy production in California.

Objectives:In accordance with the concern of global warming problem, many companies in Korea are striving to reduce greenhouse gas emissions in accordance with consumer awareness. Many studies have been reported for various products; however it is difficult to find carbonated soft drinks in Korea. The purpose of this study is to the impact of the greenhouse gas emissions, especially carbonated soft drinks in Korea.Methods:Calculation method of the greenhouse gas emissions followed “Guidelines for Carbon Footprint of Products” used in Korean Carbon Footprint Labeling. It was developed based on international standards such as ISO 14040 series. Life cycle of carbonated soft drinks was considered as a pre-manufacturing stage, manufacturing stage, distribution and disposal stage. Use stage of the product was excluded.Results and Discussion:This study shows that the package types and amounts for pre-manufacturing, manufacturing and disposal steps of carbonated soft drinks (the unit contents: 500 mL/unit, 1.5 L/unit), and also shows the results of greenhouse gas emissions. From the results, the pre-manufacturing stage of PET bottle manufacturing is the first contributor that occupy above 60% of greenhouse gas emissions. For reducing carbon emissions, low carbon manufacturing techniques for PET bottle are important. Sensitivity analysis was performed for PET bottle manufacturing, cap manufacturing and waste plastic disposal including site data and assumptions made. The sensitivity of each item was less than 7%.Conclusions:In conclusion, this study shows that the pre-manufacturing step of PET bottle and cap production have very significant impact on the greenhouse gas emissions. Therefore lightweight packages and usage of recycled plastics would be main techniques for reducing greenhouse gas emissions of carbonated soft drinks. From this study, the increment of product’s carbon footprint certification would be used as an effective policy instrument for achieving reduction goals of Korea Government. And also it could be used to spread the culture of reducing greenhouse gas emissions.

Daily emissions of greenhouse gasses have a negative impact on the quality of the atmosphere. In almost every sector there is a certain emission of these gasses. This means that every sector, whether it is the energy, industry, transport sector or the household has a part in the degradation of the environment. In this connection, many models have been developed, whose task is to reduce greenhouse gas emissions and carbon dioxide as well to improve the environmental quality. This paper will discuss the carbon footprint model. A carbon footprint is the set of greenhouse gas emissions caused by something. It can be calculated for a product, service, person or even a country, and is used to understand the impact of human activity on the earth’s climate. Also, an analysis of carbon footprint using different types of fuel for heating households will be presented.

BackgroundInhaled therapies are key components of asthma and chronic obstructive pulmonary disease (COPD) treatments. Although the use of pressurised metered-dose inhalers (pMDIs) accounts for <0.1% of global greenhouse gas emissions, their contribution to global warming has been debated and efforts are underway to reduce the carbon footprint of pMDIs. Our aim was to establish the extent to which different scenarios led to reductions in greenhouse gas emissions associated with inhaler use, and their clinical implications.MethodsWe conducted a series of scenario analyses using asthma and COPD inhaler usage data from 2019 to model carbon dioxide equivalent (CO2e) emissions reductions over a 10-year period (2020–2030) in the UK, Italy, France, Germany and Spain: switching propellant-driven pMDIs for propellant-free dry-powder inhalers (DPIs)/soft mist inhalers (SMIs); transitioning to low global warming potential (GWP) propellant (hydrofluoroalkane (HFA)-152a) pMDIs; reducing short-acting β2-agonist (SABA) use; and inhaler recycling.ResultsTransition to low-GWP pMDIs and forced switching to DPI/SMIs (excluding SABA inhalers) would reduce annual CO2e emissions by 68%–84% and 64%–71%, respectively, but with different clinical implications. Emission reductions would be greatest (82%–89%) with transition of both maintenance and SABA inhalers to low-GWP propellant. Only minimising SABA inhaler use would reduce CO2e emissions by 17%–48%. Although significant greenhouse gas emission reductions would be achieved with high rates of end-of-life recycling (81%–87% of the inhalers), transition to a low-GWP propellant would still result in greater reductions.ConclusionsWhile the absolute contribution of pMDIs to global warming is very small, substantial reductions in the carbon footprint of pMDIs can be achieved with transition to low-GWP propellant (HFA-152a) inhalers. This approach outperforms the substitution of pMDIs with DPI/SMIs while preserving patient access and choice, which are essential for optimising treatment and outcomes. These findings require confirmation in independent studies.
