Abstract Aim: This study aimed to evaluate the carbon dioxide (CO2) dynamics in tropical semi-arid reservoirs during a prolonged drought period as well as to test if the trophic state affects the CO2 saturation. Methods This study was performed in four reservoirs located in the tropical semi-arid region in the northeast of Brazil. All samplings were performed between 9 and 12 am using a Van Dorn Bottle. Samples for partial pressure of carbon dioxide (pCO2 ) measurements were taken in the sub-surface as well as samples for total phosphorus and chlorophyll-a. Correlation analysis and linear regression were used to detect relations among the calculated pCO2, water volume and chlorophyll-a. Results The water level reduction due to atypical droughts caused chlorophyll-a concentrations to increase, which in turn, led to CO2 reduction in the water. However, CO2 concentrations were very variable and an alternation between CO2 sub-saturation and super-saturation conditions was observed. This paper showed that water volume and chlorophyll-a were important regulators of CO2 in the water, as well as important carbon balance predictors in the tropical semiarid reservoirs. Conclusions The results of this paper indicate that the eutrophication allied to drastic water level reductions lead to a tendency of autotrophic metabolism of these systems.

This study shows how to measure CO2 emissions caused by railways during its life span from construction to disposal. It is now a common global concern that CO2 reduction is vital for conserving the global environment. Amidst this growing awareness, rail transport has attracted significant attention as an environmentally-friendly transportation mode due to its low emission of CO2 gas. But in many studies the amount of CO2 is calculated only during operation and doesn’t include emissions during the phase of construction of related infrastructure and rolling stocks. Rail transport can not be a truly environmentally-friendly transportation mode if it isn’t proven to emit less gases compared with other modes during a modes whole life cycle. In this paper, we introduce the method to calculate CO2 emission from the construction of infrastructure with the application of Life Cycle Assessment (LCA) and the result of a case study.

Turnaround Process

One of the most pervasive trends in the global airport industry in recent times has been the adoption of green renewable technologies. Many airports around the world have now installed photovoltaic (PV) solar systems as a key environmental measure. One of the critical areas of energy management at an airport is the provision of power and cooling at the gate, which is used during the aircraft turnaround process. Historically, the aircraft auxiliary power unit (APU) was the primary power source during the aircraft turnaround process. In recent times, airports have transitioned to the use of fixed electrical ground power (FEGP) and preconditioned air to mitigate the emissions from use of aircraft auxiliary power unit (APUs). Based on an instrumental case study research approach, this study has examined how Moi International Airport in Kenya has mitigated the airport’s carbon footprint by using a green, renewable energy system. The study’s qualitative data was examined by document analysis. The case study revealed that Moi International Airport has installed a photovoltaic (PV) solar system with a 500kW capacity that is used to primarily provide solar power at the airport’s apron area. The photovoltaic (PV) solar system has delivered Moi International Airport with an important environmental related benefit as it has enabled the airport to reduce it carbon footprint, as the photovoltaic (PV) solar system has reduced the airport’s carbon dioxide (CO2) emissions by an estimated 1,300 tonnes per annum.

Diminishing natural resources have increased the prominence and implementation of approaches to sustainable planning, design, and application. Green schools minimize environmental impact by promoting environmentally friendly attitudes, reducing the need for infrastructure facilities, and using recycling as a strategy both during and after their construction. As with other green buildings, green schools reduce dependency on fossil fuels and thus limit the emission of carbon dioxide and other pollutants. Concerning global warming, green schools have the capacity to “turn back time,” creating learning circles that elicit solutions from their student bodies. In this chapter, the authors explore the economic, ecological, and social dimensions of green schools by means of a case study of an education campus in Adana, Turkey. The authors aim to elucidate how green schools may be effective in the conservation of future resources in architectural sustainability.
