How is Environmental Sustainability a Key to Innovation?

Received: 09 February 2022;  Published: 27 April 2022;  doi: 10.21926/aeer.2202016

Abstract

The private sector plays an important role in the global climate goals and the 1.5°C target set during the Paris Agreement. Through investment in green projects and technology and energy efficiency initiatives, their carbon management strategy is paramount to achieve sustainability and good business practices. It is crucial to understand the proposals that the industry has established to reduce its environmental impact by applying supply chain optimization and technological advances or by participating in the carbo [...]

How do World-renowned Coffee Companies Manage Carbon Emissions? A Case Study of Starbucks

Received: 10 January 2022;  Published: 26 April 2022;  doi: 10.21926/aeer.2202015

Abstract

Carbon emissions are a major factor influencing climate change. Climate change also has ecological impacts, such as loss of biodiversity and loss of ecosystem functions and services. Starbucks is a large multinational company which aims to reduce their environmental impact. Starbucks’ carbon emissions in 2018 were 16,706 thousand metric tons, including 320 thousand metric tons of direct scope 1 emissions, 1,094 thousand metric tons of indirect scope 2 emissions and 14198 thousand metric tons of indirect scope 3 emi [...]

Conservation Prioritization of Ecologically Susceptible Zones at Disaggregated Levels

Received: 29 December 2021;  Published: 22 April 2022;  doi: 10.21926/aeer.2202014

Abstract

Ecologically susceptible zones (ESZs) are endowed with the distinct bio, geo, climatic, hydrological, and ecological integrity that sustain natural resources to support the livelihood of dependent populations. However, globalization and consequent anthropogenic activities have led to the erosion of the natural resource base and enhanced the levels of pollutants, triggering global environmental change, evident from changes in the climate. Alterations in the structure and the ecological integrity of ESZs may lead to [...]

The Tension Between Growth and Innovation Led Greenhouse Gas Reductions in the Information and Communication Technology and Media and Entertainment Sector: A Case Study of AT&T Inc.

Received: 13 January 2022;  Published: 15 April 2022;  doi: 10.21926/aeer.2202013

Abstract

With scientific consensus on climate change and growing public concern, firms are recognising the multiple risks associated with inaction on their Greenhouse Gas (GHG) emissions. The Information and Communications Technology (ICT) and Entertainment & Media (E&M) sectors provide essential communications services, that are foundational for much of the modern world's social and economic systems. The ICT sector has already demonstrated success in innovations that enable emissions reductions. At the same time, the ICT i [...]

Poly (Lactic Acid) (PLA)/Recycled Styrene Butadiene Rubber (rSBR) Composites

Received: 01 March 2022;  Published: 11 April 2022;  doi: 10.21926/aeer.2202012

Abstract

Recycled styrene butadiene rubber (rSBR) from waste car tires was used as a filler in poly(lactic) acid (PLA) to modify its properties. The compounds were prepared via twin-screw extrusion and molded by injection with different rSBR contents (0 to 25% wt.). Additionally, recycled rubber particle size was controlled between 125 and 1000 μm to determine the effect of this parameter. From the samples produced, a series of morphological, physical and mechanical characterizations were performed. As expected, rSBR additi [...]

Cyanobacterial Blooms and Their Implications in the Changing Environment

Received: 03 January 2022;  Published: 16 March 2022;  doi: 10.21926/aeer.2201011

Abstract

Cyanobacteria are the most ancient phytoplankton that first appeared at least 2.5 billion years ago and have a prolonged evolutionary history. They can form impenetrable and toxic blooms in aquatic ecosystems such as freshwater and marine environments. Cyanobacterial blooms produce cyanotoxins that endanger ecosystem functioning and deteriorate water quality used for recreation, drinking, and in fisheries, thus, adversely affecting human health and the economy. Some bloom-producing genera are Aphanizomenon, Plankto [...]

A Case Study of How DHL Practices Carbon Management

Received: 10 January 2022;  Published: 10 March 2022;  doi: 10.21926/aeer.2201010

Abstract

Awareness of the challenges of sustainable development, and in particular the risks of climate change, is leading to inevitable restrictions on greenhouse gas emissions. Companies must now adopt a systematic approach to sustainable development. This issue is particularly important as true carbon risk management must be introduced into the strategy of companies that will increasingly operate in a global low-carbon economy. Indeed, companies are now called upon to be accountable and transparent about the environment [...]

Relationship between Thermal Variance and Hatchery Estimates of Fertility in a Multispecies Assemblage of Anadromous Salmonids in Response to Managed Flows

Received: 15 November 2021;  Published: 22 February 2022;  doi: 10.21926/aeer.2201009

Abstract

Our study sought to identify a regional explanation for declining fertility in stocks of co-occurring salmonids in the upper Trinity River, northern California, USA. We focused on evaluating the relationship between thermal variance in river water and hatchery-measured estimates of female fertility as a function of highly managed annual flow regimes. We evaluated annual and seasonal variation in volume of flow and water temperature in response to managed flows associated with annual in-river restoration actions. We [...]

NIR Spectroscopy and Aquaphotomics Approach to Identify Soil Characteristics as a Function of the Sampling Depth

Received: 24 December 2021;  Published: 15 February 2022;  doi: 10.21926/aeer.2201008

Abstract

Soil is a very complex medium made of minerals, organic matter, microorganisms, air, and water. Vibrational spectroscopy techniques are exceptionally well-suited to be used with portable and hand-held devices. In this study, NIR spectroscopy was applied using portable instrumentation and the holistic Aquaphotomics approach to identify the differences in three Mediterranean soil profiles from Sardinia (Italy). The soil samples (95) collected from alluvial and loess-sampling sites in the three study areas of North Sa [...]

How Might Changing Climate Limit Cyanobacteria Growth in Shallow Prairie Lakes? An Empirical Space-For-Time Evaluation of the Potential Role of Increasing Sulfate

Received: 20 November 2021;  Published: 15 February 2022;  doi: 10.21926/aeer.2201007

Abstract

Cyanobacteria blooms alter aquatic ecosystems and occur frequently in shallow prairie lakes, which are predicted to increase in salinity as the regional climate becomes hotter and drier. However, flat landscapes that experience depression bottom salinity with high concentrations of sulfate in addition to sodium and chloride, may mitigate nutrient increases or even inhibit cyanobacteria growth. Cyanobacteria can dominate shallow lakes with low N:P ratios because many cyanobacteria species fix dissolved N2, whether d [...]
