A new government report on climate change shows that global emissions of greenhouse gases have increased to very high levels despite various policies to reduce climate change. Building energy accounts for 40% of the world’s energy consumption and accounts for 33% of the world’s greenhouse gas emissions. This study applied the LEAP (Long-range energy alternatives planning) model and Bass diffusion method for predicting the total energy consumption and GHG (Greenhouse Gas) emissions from the residential and commercial building sector of Sejong City in South Korea. Then, using the Bass diffusion model, three scenarios were analyzed (REST: Renewable energy supply target, BES: Building energy saving, BEP: Building energy policy) for GHG reduction. The GHG emissions for Sejong City for 2015–2030 were analyzed, and the past and future GHG emissions of the city were predicted in a Business-as-Usual (BAU) scenario. In the REST scenario, the GHG emissions would attain a 24.5% reduction and, in the BES scenario, the GHG emissions would attain 12.81% reduction by 2030. Finally, the BEP scenario shows the potential for a 19.81% GHG reduction. These results could be used to guide the planning and development of the new city.

A substantial share of the building sector in global energy demand has attracted scholars to focus on the energy efficiency of the building sector. The building’s energy consumption has been projected to increase due to mass urbanization, high living comfort standards, and, more importantly, climate change. While climate change has potential impacts on the rate of energy consumption in buildings, several studies have shown that these impacts differ from one region to another. In response, this paper aimed to investigate the impact of climate change on the heating and cooling energy demands of buildings as influential variables in building energy consumption in the city of Poznan, Poland. In this sense, through the statistical downscaling method and considering the most recent Typical Meteorological Year (2004–2018) as the baseline, the future weather data for 2050 and 2080 of the city of Poznan were produced according to the HadCM3 and A2 GHG scenario. These generated files were then used to simulate the energy demands in 16 building prototypes of the ASHRAE 90.1 standard. The results indicate an average increase in cooling load and a decrease in heating load at 135% and 40% , respectively, by 2080. Due to the higher share of heating load, the total thermal load of the buildings decreased within the study period. Therefore, while the total thermal load is currently under the decrease, to avoid its rise in the future, serious measures should be taken to control the increased cooling demand and, consequently, thermal load and GHG emissions.

The primary energy consumption and greenhouse gas emissions from nickel smelting products have been assessed through case studies using a process model based on mass and energy balance. The required primary energy for producing nickel metal, nickel oxide, ferronickel, and nickel pig iron is 174 GJ/t alloy (174 GJ/t contained Ni), 369 GJ/t alloy (485 GJ/t contained Ni), 110 GJ/t alloy (309 GJ/t contained Ni), and 60 GJ/t alloy (598 GJ/t contained Ni), respectively. Furthermore, the associated GHG emissions are 14 tCO2-eq/t alloy (14 tCO2-eq/t contained Ni), 30 t CO2-eq/t alloy (40 t CO2-eq/t contained Ni), 6 t CO2-eq/t alloy (18 t CO2-eq/t contained Ni), and 7 t CO2-eq/t alloy (69 t CO2-eq/t contained Ni). A possible carbon emission reduction can be observed by comparing ore type, ore grade, and electricity source, as well as allocation strategy. The suggested process model overcomes the limitation of a conventional life cycle assessment study which considers the process as a ‘black box’ and allows for an identification of further possibilities to implement sustainable nickel production.

This paper attempts to discuss the embodied energy consumption and embodied greenhouse gas emissions in manufacturing industry. Based the on input-output theory, this paper establishes the calculation model, which gives the calculation of embodied energy consumption and embodied greenhouse gas emissions of 2002 and 2007 respectively. By comparison, it draws the conclusion that the total direct energy consumption of 2007 is much more than the year of 2002, while the total embodied energy consumption is less than the year of 2002. However, Non-metallic mineral products, Metal smelting and pressing and Electric equipment and machinery perform otherwise. The reason accounting for the calculation results is that the embodied energy intensity is greatly decreased.

Research Question: This paper aims to analyse the impact of reported greenhouse gas (GHG) emissions on financial performance of companies operating in the chemical industry from Central-Eastern Europe over the period 2015-2019. Motivation: Currently, the climate change and global warming have become highly topical due to their progressively visible destructive effects worldwide on the environment, society, and economic activity. Idea: To offer the suitable information to all its stakeholders, each company should identify the necessary information, measure it, make it useful, and take reasonable steps to ensure that it’s accurate; our research investigates the effect of reported greenhouse gas emissions on return on sales, as a measure of business performance. Data: The paper is based on panel data extracted from non-financial and/or annual reports for the top 10 largest companies operating in the chemical industry geographically located in Central-Eastern Europe covering the time frame 2015-2019. The final sample consists of 34 firms and 134 firm-year observations. Tools: A multiple linear regression model was designed and applied, having return on sales as the dependent variable and GHG emissions as the independent variable. Findings: The findings of our study confirm that a lower level of GHG emissions will generate an increase in return on sales, consequently, the environmental performance reported in terms of controlling for GHG emissions enhances the financial performance measured as return on sales ratio. Contribution: The paper contributes to the literature on climate change, revealing a negative, but significant effect of GHG emissions on financial performance and endorsing that companies which today pay less attention to this global concern, tomorrow will face difficulties in terms of sales.

AbstractMolybdenum is mainly used as an alloy material in the iron and steel industry and typically in the form of ferromolybdenum (FeMo). The current study aims to evaluate the energy consumption and greenhouse gas emissions (GHG) of four ferromolybdenum production cases using inventory inputs from a process model based on mass and energy conservations. The total energy required for producing 1 tonne of FeMo can vary between 29.1 GJ/t FeMo and 188.6 GJ/t FeMo. Furthermore, the corresponding GHG emissions differ from 3.16 tCO2-eq/t FeMo to 14.79 tCO2-eq/t FeMo. The main variances are from the mining and beneficiation stages. The differences in these stages come from the beneficiation degree (ore grade) and the mine type (i.e., co-product from copper mining). Furthermore, the mine type has a larger impact on the total energy consumption and GHG emissions than the beneficiation degree. More specifically, FeMo produced as co-product from copper mining has a lower environmental impact measured as the energy consumption and GHG emission among all the four cases. The inventory, consumed energy or associated GHG emission is independent on the initial ore grade and mine type in the downstream production stages such as roasting and smelting. Also, transport has the least impact on the energy consumption and GHG emission among all production stages.

Changes in seasonal weather cycles, a growing number of extreme phenomena, an upward trend in temperature and changes in the distribution of rainfall, significantly affect the functioning and effectiveness of agriculture. However, agriculture plays a major role in the emergence and intensification of these phenomena. The aim of the article is to present, analyse and evaluate the relations between agriculture and climate, with particular emphasis on greenhouse gas (GHG) emissions from agriculture in these relations. A cause-and-effect analysis was conducted based on literature studies, using the descriptive statistics method and analysis of the development trend. The basis for analysis were data on GHG emissions in the European Union (EU-28). The contribution of agriculture to the EU’s greenhouse gas emissions, albeit slightly but still increasing in recent years. The level of this emission is determined primarily by the type of agricultural activity conducted – animal production is definitely responsible for higher emissions than plant production. It is difficult to present a universal model of agricultural adaptation to climate change and a set of actions limiting the negative impact of agricultural production on climate. This is hindered by both the specificity of the agricultural sector and the large diversity of local conditions and applied farming practices. The opportunity to increase the effectiveness of actions taken may be a better connection between the implementation of objectives including the reduction of the causes and negative consequences of climate change and the objectives of sustainable agricultural development.

The relationship between agriculture and climate change is two-sided. Agriculture is the branch of the economy most affected by the ongoing processes. It is also a large emitter of greenhouse gases and there are more and more voices about the need to reduce emissions. The purpose of the study was, based on FADN (Farm Accountancy Data Network) data, to determine the structure of greenhouse gas emissions in farms and to identify types of farms where it is possible to reduce GHG (greenhouse gas) emissions through better energy use. The emission volume was determined on the basis of the IPCC (Intergovernmental Panel on Climate Change) methodology modified for the FADN data. The emissions related to the production of energy were found to be of minor importance compared to other emission sources. Only in the horticultural crop type is the emission from the Energy section the dominant stream of GHG emission. The greatest emissions come from livestock production. Therefore, the emphasis on reducing emissions should not be placed on the Energy sector because, except for the type of horticultural farm, there is not much potential for reduction. The introduction of taxes for GHG emissions at the level of 27.31 EUR/t would reduce farm income from 21% for the type of field crops to 40% for the type of herbivorous animals. The exception is low-emission permanent crops, where the decrease in income would be only 3.85%.
