The carbon footprint is one of the main factors for measuring CO emissions2, this atmospheric gas represents a worldwide environmental problem. Currently, universities are making inroads into the solution through the quantification and mitigation of CO2. Academic activities and the delivery of physical documents generate high amounts of paper consumption and consequently levels of CO2, which establishes a problem. The objective is to estimate the carbon footprint of the Universidad Técnica Estatal de Quevedo (UTEQ) located in Ecuador. The methodology employed consisted of a quantification of the number of files registered in the academic system per year. The files were multiplied by an average number of sheets obtained through a survey applied to teachers. The carbon footprint was determined by multiplying the CO emission factor2 by annual paper consumption. The emissions obtained are 3.21 ton CO2 eq to 3.00 ton CO2 eq for the year 2020-2021 and 2021-2022, respectively. The virtual education implemented at UTEQ contributed to the fulfillment of climate change objectives, due to the non-emitted CO2 emissions determined in this study, an issue that is related to the achievement of a green university.

Abstract: A simple transfer function has been used to predict indoor temperature and humidity from outdoor climate. Using downscaled output from the Hadley Model (HadCM3) changes in indoor climate through to 2100 were predicted for an idealised unheated room at a number of European sites. The potential threats to paper and the risk of salt damage were predicted using damage functions. Although paper faces an increased risk in some temperate locations, salt weathering can increase or decrease dependent on location. Many future indoor climates may already exist at other locations, so communication throughout the heritage sector offers examples for the management of future challenges. Climate change is relatively slow so there is ample time for the adoption of good practices at these locations. [Copyright &y& Elsevier]

Abstract: This paper estimates the effects of humidity and temperature on mortality rates in the United States (c. 1973–2002) in order to provide an insight into the potential health impacts of climate change. I find that humidity, like temperature, is an important determinant of mortality. Coupled with Hadley CM3 climate-change predictions, I project that mortality rates are likely to change little on the aggregate for the United States. However, distributional impacts matter: mortality rates are likely to decline in cold and dry areas, but increase in hot and humid areas. Further, accounting for humidity has important implications for evaluating these distributional effects. [Copyright &y& Elsevier]

• Cellulose-based solutions can improve environmental performance of food packaging. • Food products require specific barrier functions from cellulose-based packaging. • Eco-design enables quantifying environmental performance and identifying trade-offs. • Fulfilling the barrier requirements for food product packaging is crucial. This short communication describes the climate change impacts of using cellulose, and more precisely cellulosic fiber-based materials, in food packaging, representing current and emerging industrial state of the art technology, without specific reference to current scientific advances. First, the different types of cellulosic fiber-based packaging materials, which can be used to replace fossil-based packaging materials, are presented for flexible and rigid applications. The focus is on technological solutions with packaging properties that enable the protection of commonly sold food products. The manufacturing processes associated with these cellulosic fiber-based materials is described and the environmental impact assessment of 4 selected case studies presented: stand-up pouches, flexible flow wraps, frozen or chilled food trays, and molded pulp lids. A simplified eco-design Life Cycle Assessment (LCA) was then performed to compare each solution with its fossil-based counterpart. Differences and similarities between the various cellulosic solutions have been identified. Furthermore, the assessment confirms that cellulosic fiber-based materials have reduced environmental impacts as compared to fossil-based counterparts, if a similar packaging weight is obtained. Indeed, all impacts of plastics are between 3 and 5 kg CO 2 eq/kg, while all impacts of cellulosic fiber-based materials are below 1.5 kg CO 2 eq/kg. [ABSTRACT FROM AUTHOR]
