The Impact

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

AbstractIt has become a standard for researchers carrying out biotechnology projects to do a life cycle assessment (LCA). This is a process for assessing the environmental impact of a technology, product or policy. Doing so is no simple matter, and in the last decades, a rich set of methodologies has developed around LCA. However, the proper methods and meanings of the process remain contested. Preceding the development of the international standard that now governs LCA, there was a lively debate in the academic community about the inclusion of ‘values’ within the process. We revisit this debate and reconsider the way forward for LCA. We set out ways in which those outside of science can provide input into LCAs by informing the value assumptions at stake. At the same time, we will emphasize that the role of those within the scientific community need not (and sometimes, will inevitably not) involve value-free inquiry. We carry out this exploration through a case study of a particular technology project that sought ways to produce industrial and consumer products from algal oils.

Investment Decision Making

Energy efficiency is an important means for sustainable manufacturing. One action for manufacturing companies to improve energy efficiency is through investments. While these investments often are profitable, opportunities remain unexploited. This paper explores the structural context of the investment decision-making process by examining the associated activities, procedures, and the role of information. While the structural context may limit complex investments that do not fit predefined rules and controls, such as energy efficiency and other sustainability-related investments, it remains a scarcely studied aspect of investment decision-making for energy efficiency investments. Method-wise, the paper is based on a case study of a major investment at a pulp and paper company, motivated and justified based on productivity, strategic, energy, and sustainability rationales. The paper contributes with illustrating how configurations of internal investment activities and procedures may be crucial for sustainability-related investments to pass through the investment process. Moreover, the configuration of activities and procedures is also indicated as influential for the way in which an investment is executed. Hence, for energy efficiency and other sustainability-related investments to make business sense constitutes more than achieving desirable payback periods; the structural context should be considered.

The constant growth of the world’s population has generated various changes in the use of the diversity of the resources provided to us by the planet. Considering that by properly managing energy in air conditioning systems correctly, it collaborates in the fight against climate change, reducing the excessive use of fossil fuels and, therefore, the emission of CO2 and other greenhouse gases, creating an environment of comfort in industrial sectors, businesses, companies, homes, among others. The objective of this research is to validate the instrument considering the information obtained about smart devices applied in air conditioning systems and their improvement in energy efficiency. The methodology applied consisted of a field study conducted through an online survey that was directed at 226 students and professionals from three provinces of the Republic of Ecuador. To validate the data obtained in the instrument, the exploratory factor analysis was performed also of the principal components in the last phase it was obtained in factor transformation matrix (0.986), which demonstrates the validity of the study. To apply the KMO test and Bartlett’s sphericity, the following ranges (≥0.6) y (<0.05) were considered respectively.

Self Differentiation

AbstractSince their inception, climate change negotiations have stalled because of the scope of parties’ mitigation responsibilities under the United Nations Framework Convention on Climate Change (UNFCCC). The concept of common but differentiated responsibilities and respective capabilities (CBDR-RC) became a core principle of the framework to ensure consensus on a global climate policy in 1992 and to promote differentiation. By letting each country assess its current responsibilities and capacities for climate mitigation through their nationally determined contributions (NDCs), the Paris Agreement has built on the principle of CBDR-RC and promoted self-differentiation. As the concept evolved, the role of emerging economies has been a particular focus of discussions. Academia is still grappling with the revised meaning of CBDR-RC and the newly introduced NDCs. This article contributes to the discussion by analyzing the role of emerging economies in climate governance through the lens of regional responsibility. In particular, it discusses how cooperation can be a more effective way to ensure differentiation, especially by distinguishing emerging economies from other developing countries with fewer capacities. The article uses the Amazon rainforest as a case study, discussing Brazil’s role within the region. Building on lessons from regional schemes that have successfully promoted climate mitigation, the article looks at the Amazon Cooperation Treaty Organization (ACTO) as an avenue for enhanced cooperation at the regional level.

This case study explores the application of the Lead-user method in the development of medical applications based on Wireless Sensor Network (WSN) technology by three independent research teams. The study also reflects on the role of student teams as Innovation Intermediaries (Howells, 2006; O’Flaherty, et al. 2013) and as a resource for discovering new medical devices. This exercise produced surprising results, with the emergence of diverse WSN technology product concepts applied to Geriatric Falls Detection & Analysis, Sport Cardiac Screening and Critical Care Vital signs within accident and emergency environments. This case highlights the segmented nature of medical areas and the difficulty in applying a generic WSN technology to meet the functional requirements of the broader individual medical domains. It questions the appropriateness of applying ‘total’ highly functional technologies broadly across highly specialised niche medical areas.
