AbstractToday the requirements for reducing the impact of our manufacturing activities are increasing as the world awakes to and addresses the environmental impacts of our society. Energy consumption, greenhouse gas emissions, materials availability and use, environmental impact levels, etc. are all topics of interest. Semiconductor manufacturing in general and process steps such as CMP are not exempt from this and, in many cases, the industry has led the efforts in reducing impacts. This paper will first review some of the drivers for sustainable manufacturing, then define some of the terms that will be useful for determining the engineering aspects of sustainability and sustainable manufacturing, as well as metrics for assessing the impact of manufacturing in general and CMP in particular. An assessments of CMP will be given to illustrate the potential for “design for the environment” in CMP and related processes. Consideration will be given to research opportunities, including process modeling, that this focus provides to CMP researchers, consumable suppliers and industry.

This study aimed to explore the impact of the Places to Grow Plan 2006 on travel behavior of the work commuters living in GTHA. A comparative analysis was done between the year 2001 and 2011 which represent the situations five year before and after the implementation of the Plan. Data were collected from Transportation Tomorrow Survey. The study revealed that in 2011, energy consumption by motorized vehicles increased in the Traffic Assessment Zones of GTHA around the Growth Centres designated by the Places to Grow Plan. Active transportation increased mainly in Toronto in 2011. It is apprehended that the intensification strategy of the Places to Grow Plan contributed in increasing the energy consumption of work commuters either by increasing the number of trips or length of trips made by motorized vehicles (including cars and different forms of transit) which also affect the Greenhouse Gas emissions in the atmosphere.

AbstractTo perform their business operations, telecommunication companies need to consume energy. This paper aims to analyze and compare the energy consumption and their greenhouse gas emissions for there of the biggest telecommunication companies: Vodafone, Orange and Telekom. Although the scientific literature proposed some analysis on the environmental measures that the telecommunication companies have to take, there is a shortage of researchers focused on GRI reporting data and the pairwise comparison method. The authors compared these telecommunication companies’ emissions under the following criteria: energy consumption (GRI 302-1), scope 1 (GRI 305-1), scope 2 (GRI 305-2) and scope 3 (GRI 305-3) greenhouse gas emissions, reduction of emissions (GRI 305-5), using the pairwise comparison method. To reduce their emissions, companies developed a sustainability strategy. This paper will further emphasize what are the plans to reduce emissions for the company which, following the analysis, pollutes the most. To provide an overview of the future of the company which, by the analysis, pollutes the most, the authors have identified and analyzed what are the main actions that the company should take to reduce their impact on the environment. To do so, the authors firstly analyze the causes of the pollution produced by the telecommunication company using Ishikawa diagram. Then, it identifies what are the main organizational processes that can be improved using APQC standardization, to show that the improvement can be made if the organization adjusts their organizational processes. This paper is an enhancement to the studies form the field because it provides a comparative analysis on three of the most competitive telecommunication companies in the world, uses GRI criteria and pairwise comparison method and gives an overview on the next steps for the telecommunication company to reduce their greenhouse gas emissions.

The Impact

Companies around the world are increasingly expected to report their greenhouse gas emissions. Currently there are various formulas to calculate emissions, and there are different reporting formats. Most of the reporting formats are paper-based or non-readable-by-machine formats. The emissions of companies will influence their accounting results due to ‘cap & trade’ systems or environmental taxes. Analyses of financial impacts are important for management decisions and corporate evaluations by interested third parties. A standardized reporting format for GHG (greenhouse gas) emissions is critical for reliable analysis of the impact of emissions on finances. This paper proposes an XBRL (eXtensible Business Markup Language) format as the foundation for standardizing the emissions reporting formats, and provides a preliminary XBRL taxonomy for emissions reporting. XBRL makes it possible to combine the financial reports and the emissions reports. Evaluations of the emissions impact are easier for both managers of the company and external parties, even if a large number of emissions reports must be analyzed.

The Impact

There have been efforts to restrict older trucks in many jurisdictions all over the world. The primary goal of the restrictions is to minimize greenhouse gas emissions. In addition to the environmental benefits, it is also possible that the truck age restriction could contribute to the enhancement of traffic safety. Older trucks are subject to longer travel-miles than newer trucks and tend to have higher mechanical failure rates. Extremely few studies have been done to explore the impact of trucks’ age on their crash occurrence due to mechanical problems. This study aims to investigate the association between the truck crashes due to mechanical issues and the truck age. Two approaches are adopted to achieve the objective. First, a chi-square test reveals that the proportions of the mechanical failures among older trucks are higher than those among newer ones ( χ 2  = 256.199, p < 0.0001 ). Second, the modeling results indicate that the number of truck crashes due to mechanical failures is significantly increased by the truck age. The findings suggest that policies restricting older trucks should consider not only environmental effects but also traffic safety benefits.

Wind is increasingly used as a renewable energy all around the world. Although wind turbines help reduce greenhouse gas emissions, the costs to wildlife cannot be overlooked. To date, monitoring programs and research have mainly focused on the impact of wind farms on birds but negative effects on bats have also reported. Here we compile information related to European free–tailed bat deaths at wind farms in southern Spain. In a world where the demand for renewable energy is rising we highlight the need to better understand and prevent bat fatalities.

The Impact

The article is devoted to the review of the main materials of the international conference Eurocoke-2021, which took place on October 5-6 in Amsterdam, the Netherlands. Despite the fact that the conference is named as European, the representatives of the world's leading firms and research centers from the EU, England, Australia, India, USA, China, Ukraine and other countries took part in its work. The article summarizes the main results and conclusions of the reports and discussions. As the most of speakers noted, that despite the impact of the global recession and the logistical difficulties caused by the COVID-19 pandemic, as well as the China's ban to use Australian coal, a significant change in the global coal market is not expected in the near future. China's trade policy has led mainly to a redistribution of markets for Australian, American, Canadian and Russian coal. Technologies and researches to replace some of the components of the coking coal charge with a cheaper coal grades or carbonaceous materials of plant origin in order to reduce the cost of coke and steel are still relevant. The strict requirements for limiting greenhouse gas emissions are forcing coke and steel producers to modernize the existing traditional production facilities (including using integrated technologies) to reduce emissions and improve the efficiency of the CO2 capturing and utilization. In the world steel production in the next decade, a significant increase in the share of technologies focused on abandoning coke and blast furnace production is hardly possible due to the high cost and duration of the corresponding projects. Keywords: coke production, steel industry, world coking coal market, steel market, trends, recession, logistics, COVID-19, greenhouse gas emissions, decarbonization, direct iron reduction, integrated technologies, stamped charge coking, biomass, catalysis.
