Global warming is a reality due to the curent level of greenhouse gas emissions globally. Housing construction should take into account factors which contribute to global warming while making the construction affordable in view of the greenhouse gas emissions and the continually increasing energy costs. It is important that housing construction overcomes the irrationality of the current conventional construction method which is not only expensive but has poor thermal performance and ignores the significant environmental impact of high embodied energy of the building process which contributes to the greenhouse gas emissions. Because of this there is a need for developing improved low cost sustainable building techniques. This paper presents an innovative rammed earth core concrete jacket walling system that can provide significant improvements in environmental impact, comfort and cost of both building the house and the cost of operational energy. The construction uses mainly local natural materials with very little high energy processing there by reducing the embodied energy of the construction. Not only using local materials in this construction but also only basic building skills are required for construction workers and therefore the system is ideally suited to rural areas and has potential application to developing countries. This method of construction has better performance in case of earth quakes which saves many lives. The paper presents a discussion of the efficiency of such high thermal mass solutions and describes the construction process.

In the last few decades, climate change and the global warming have emerged as important environmental issues. The cause of global warming is the increase of greenhouse gas emissions (GHG). There are several greenhouse gases responsible for global warming: water vapor, carbon dioxide (CO2), methane, nitrous oxides, chlorofluorocarbons (CFCs) and others. They are mostly the result of the fossil fuels' combustion in cars, buildings, factories, and power plants. The gas responsible for the most of the global warming is carbon dioxide (CO2). This increase in the greenhouse gas emissions leads to a greater interest of the consumers, board management and stakeholders in the environmental impact of their activities, products and services.The verification of the Carbon Footprint of distribution oil immersed transformer, presented in this paper, was recognized as an opportunity for the company to understand its own environmental impact and to identify inefficiencies and opportunities within its business.Carbon Footprint of a Product (CFP) is a rather new term closely related to the greenhouse gas emissions. The CFP is considered as a total of the greenhouse emissions generated during the life cycle of a product – that is, from raw material acquisition or generation from natural resources to a final disposal. It is described within the standard ISO 14067:2018 Carbon footprint of products – Requirements and guidelines for quantification [1]. This standard belongs to the environmental series ISO 14000 and enables the organization to demonstrate its environmental responsibility.Life Cycle Assessment (LCA), as well as the Carbon Footprint of products together with environmental impact of the product, are shown in this paper in accordance with standard ISO 14067:2018. The LCA is a method for the quantification of the environmental impacts of individual products. It takes into account a complete life cycle, starting from a raw material production, until the product’s final disposal or materials’ recycling in accordance with ISO 14040 [2] and ISO 14044 [3]. Greenhouse gases are expressed in mass-based CO2 equivalents (CO2e), which is the unit of measurement in the ISO 14067:2018 standard. The functional unit in ISO 14067:2018 can be either a product or a service. In this paper, the functional unit was the product – oil immersed distribution transformer, in four product variations. The LCA scope used in the preparation of this study was "cradle to gate" – it covers the CFP from the acquisition of the raw materials ("cradle") up to dispatch from the factory ("gate").The objectives of product life cycle considerations in Končar D&ST Inc. are to reduce the use of natural resources and emissions to the environment, as well as to improve social performance at different stages of the product life cycle.By linking the economic and ecological dimension of the production, different aspects during realization of product in all phases of the life cycle come together. In this way company achieves cleaner products and processes, competitive advantage in the market and improved platform that will meet the needs of the changing business climate.Lifecycle thinking is based on the principles of reducing environmental impacts at the beginning of product creation, giving a wider picture of material and energy flow and ultimately environmental pollution prevention. These principles are organized in Končar D&ST Inc. internally by planning and introducing cleaner manufacturing processes, environmental protection management and eco-design.Incorporating ISO 14067:2018 into company business is recognized as an opportunity for transparent communication to interested parties, incorporating CO2 emissions into annual reports and as a baseline information for a first step towards managing carbon emissions.

The aim of the study was to analyze emissions in the supply chain and to identify, based on a literature analysis, which supply chain strategies could contribute to reducing these emissions. A broad spectrum of new supply chain strategy solutions was identified and, based on simulations of selected products, conclusions were drawn and the advantages and disadvantages of theoretical solutions were presented for individual cases. A critical analysis of the literature and simulation methods were used to illustrate the problem presented in this paper, to identify the factors causing greenhouse gas emissions and to draw conclusions in the form of proposals to redesign existing strategies, considering the factors determining the increase in pollution caused by the performed logistics processes. The results of the simulations and the literature analysis indicate that solutions related to the redesign of strategies must consider the specificity of the product and the nature of the chain. Not all proposed strategies are applicable to all chains, and each new strategy must be carefully considered and consider many factors. An important element to reduce the negative environmental impact of chains is a well-thought-out relationship with suppliers, a well-chosen and adapted logistics infrastructure, including means of transport. The presented solutions clearly indicate that the environmental aspect plays an increasingly important role in chain management and influences the applied chain strategies. However, reducing the environmental impact of a chain is not a revolutionary approach and an easy-to-implement strategy change, but a well-thought-out, long-term process that considers the specifics of the products, the possibilities of alternative sourcing and distribution modes, and the need to invest in logistics infrastructure to make it as environmentally neutral as possible.

To what degree do serious issues require serious consequences for politicians who fail to address them? Should politicians who fail to keep campaign promises have greater consequences than not being reelected? In this work of philosophical short story fiction, Brian Greenwald is running a unique presidential campaign. Not only is he a single-issue candidate for stopping global warming, but an ominous figure follows him everywhere with the promise to kill him at the end of his term if he fails to move the needle. The electorate knows this, and elects Greenwald President in a landslide. Everything he does in office is focused on the single goal of lower greenhouse gas emissions. At the end of his first term emissions have gone flat, but not down. By the end of his second term, even after exceptional efforts, global greenhouse gas emissions have failed to significantly fall. Good to his word, the ominous figure kills him for failing to deliver.

Greater American regulatory moving from federal to state governments has resulted in varying levels of environmental legislation and regulation. One example is the cap-and-trade system in California, which has been deemed a success in limiting greenhouse gas emissions as well as in earning revenue for the state. However, the coinciding production rates for polluting organizations has not been analyzed on a macro level. This study examined the air pollution and production rates of electricity organizations operating in California since cap-and-trade went into effect and found that since the legislation took effect, not only did production decreased slightly, but also, contrary to much analysis, the rates of air pollution from these organizations increased sharply.

Food insecurity is a recurrent condition in which members of a household do not have enough food to cover their nutritional needs; this condition contributes to increasing social vulnerability of those affected. In Peru, there are more than 9 million people who suffer this condition, which generates malnutrition and anemia, mostly in children. On the other hand, the waste of food is associated with production the large amounts of greenhouse gas emissions that affect global warming. According to reports in Peru, 20% of what is food produced becomes waste. This scenario in terms of food for Peruvians represents 3 billion calories in wasted food that could feed 2 million people. The Peruvian Food Bank manages food donations, ensuring this food can reach people in need through humanitarian aid entities. This applied research work uses the tools of operations research to determine a solution to the problem of maximizing the combination of food orders to be distributed based on their total nutritional value to the beneficiaries, seeking maximum coverage and minimum logistic costs.
