<p>This paper summarises the results of a survey carried out amongst the student population of one of the largest Greek Technological Educational Institutes. It explores attitudes toward the environment in general and then, more specifically, toward global warming and global warming-mitigation technologies. It also explores student understanding of sources of carbon dioxide and climate change-mitigation technologies, such as carbon dioxide capture and storage (CCS). Further, it analyses responses to questions about willingness of respondents to pay to solve global warming. The data was collected in October and November of 2011 using a structured questionnaire which was first formulated in English and then translated into Greek. The analysis was performed using the statistical package SPSS v17.0 and focused on descriptive statistics, in order to compare the average ratings for the different statements.</p> <div> <p>The present study concludes that university students in Greece are overwhelmingly positively disposed towards the environment with the majority of respondents believing that protecting the environment should have priority over economic considerations. Students also view the effects of global warming as serious enough to warrant action and state their belief that the current generation should meet its own needs without compromising the ability of future generations to meet their own. Moreover, the majority of the participants are against the development of nuclear energy, favoring RES (solar wind and bioenergy), and energy conservation technologies. However, the study has also identified a lack of understanding in regards to sources of carbon dioxide. The majority of the respondents do not seem to know that oceans act as sinks of CO<sub>2</sub> emissions or that the housing stock is a significant contributor to this problem.&nbsp;</p> </div> <p>&nbsp;</p>

In today’s world, owing to industrial expansion, urbanization, the rapid growth of the human population, and the high standard of living, the utilization of the most advanced technologies is unavoidable. The enhanced anthropogenic activities worldwide result in a continuous increase in global warming potential, thereby raising a global concern. The constant rise in global warming potential forces the world to mitigate greenhouse gases, particularly carbon dioxide. Carbon dioxide is considered as the primary contributor responsible for global warming and climatic changes. The global anthropogenic carbon dioxide emissions released into the atmosphere can eventually deteriorate the environment and endanger the ecosystem. Combating global warming is one of the main challenges in achieving sustainable development. Carbon capture and storage is a potential solution to mitigate carbon dioxide emissions. There are three main methods for carbon capture and storage: post-combustion, pre-combustion, and oxy-fuel combustion. Among them, post-combustion is used in thermal power plants and industrial sectors, all of which contribute a significant amount of carbon dioxide. Different techniques such as physical and chemical absorption, physical and chemical adsorption, membrane separation, and cryogenic distillation used for carbon capture are thoroughly discussed and presented. Currently, there are various materials including absorbents, adsorbents, and membranes used in carbon dioxide capture. Still, there is a search for new and novel materials and processes for separating and capturing carbon dioxide. This review article provides a comprehensive review of different methods, techniques, materials, and processes used for separating and capturing carbon dioxide from significant stationary point sources.

AbstractThe phenomenon of anthropogenic climate change has been identified as a threat multiplier for many human-related concerns. Carbon capture and storage (CCS) can, in combination with several other mitigation technologies, alleviate global warming by reducing carbon dioxide (CO2) emissions. Reducing climate change-related risks via CCS creates another risk, smaller in extent: the risk that some of the stored CO2 leaks out of the storage complex. This article reviews European legislation and evaluates how one of its objectives, that private liabilities of CCS-related leakage risks are not socialized, is ensured. Slight modifications of European legislation are suggested in order to prevent an indefinite liability of CCS operators in case a storage complex turns out to be unexpectedly and unavoidably prone to CO2 leakages. Official German and Hungarian financial precaution specifications are contrasted and related to this article’s finding that the state budget is sufficiently hedged against the expected value of climate-related leakage compensation costs of poorly managed storage complexes if 3 to 6% of a CCS operator’s emission-related revenues are diverted into a financial precaution fund.

Change Mitigation

The latest technologies for climate change mitigation are carbon capture and storage (CCS). Some countries are developing CCS projects, and they are currently at different stages of deployment. Despite the signing of international agreements on climate change mitigation, Russia’s efforts to develop and implement CCS technologies are quite limited. Therefore, it is vital that people are aware of the importance of carbon dioxide capture, utilization, and storage. The purpose of this article is to produce guidelines and toolkits to form a system of measures aimed at raising awareness of the Russian society on carbon dioxide capture and storage technologies. The paper discusses the key findings of several recent studies on the topic, e.g., a study focusing on the level of environmental consciousness among St. Petersburg students; a content analysis of the Russian school textbooks; a study of environmental groups in Russian social media; and an experimental study on creating eco-comics and posters as educational tools for promoting environmental awareness. A multi-level system of educational activities is proposed, including events for preschoolers, schoolchildren, students, and adults.

Abstract A theory of capillary-gravitational waves in the transition region between seawater and liquid carbon dioxide in deep oceans is proposed. It is shown that the thickness of the transition layer affects the properties of capillary-gravity waves. The question of the structure and stability of wave disturbances at the interface between seawater and liquefied carbon dioxide is essential for the safe storage of liquefied carbon dioxide in the ocean. This is an important issue on the current agenda in light of global warming.

Increasing emissions of greenhouse gases have caused climate change as well as global warming. As a result, reducing carbon dioxide production or its disposal is very important. One way to solve this problem is to inject carbon dioxide into oil tanks to increase hydrocarbon extraction. In this research, a simulation of carbon dioxide storage in an oil reservoir has been performed using a hybrid method. The results show that horizontal wells have better potential than vertical wells for storage.
