Carbon dioxide (CO2) is one of the greenhouse gases which cause global warming. The amount of fossil fuels consumed to meet the demands in the areas of power and transportation is projected to increase in the upcoming years. Depending on carbon content, each power plant fuel has its own potential to produce carbon dioxide. Similarly, the humans consume food containing carbohydrates (CH), fat, and protein which emit CO2 due to metabolism. The biology literature uses respiratory quotient (RQ), defined as the ratio of CO2 moles exhausted per mole of O2 consumed within the body, to estimate CO2 loading in the blood stream and CO2 in nasal exhaust. Here, we apply that principle in the field of combustion to relate the RQ to CO2 emitted in tons per GJ of energy released when a fuel is combusted. The RQ value of a fuel can be determined either from fuel chemical formulae (from ultimate analyses for most liquid and solid fuels of known composition) or from exhaust gas analyses. RQ ranges from 0.5 for methane (CH4) to 1 for pure carbon. Based on the results obtained, the lesser the value of “RQ” of a fuel, the lower its global warming potential. This methodology can be further extended for an “online instantaneous measurement of CO2” in automobiles based on actual fuel use irrespective of fuel composition.

Abstract The construction industry has a major influence on man-made carbon dioxide emissions. Being sustainable also means reducing or neutralizing our carbon dioxide pollution in the future. This research and the corresponding work are therefore guided by the following question: Is it possible and useful to conduct life cycle assessments and at the same time analyze the environmental impact of the construction sector? In the context of this work, a life cycle assessment of a building is performed using the example of a hotel building. All construction elements of the thermal envelope are examined from an environmental point of view by considering the global warming potential of each part of the construction. The aim of the study is to draw conclusions about the parameters that are decisive for the construction of a hotel building from an ecological standpoint in the production phase. Based on the results of the study, we want to drive the development of a “future” energy performance certificate forward that graphically illustrates the evaluation of buildings under both aspects - energy efficiency (final energy) and sustainability (GWP - global warming potential).

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.

The edge required by renewable technologies is provided by a simplification of the energy supply train. This simplification consists in no longer eating animals. Animals have upside-down energy returned on energy invested values (EROIs), with up to 30 times as much energy having to be put into raising them as we get out of them through eating them or their products. At one time, when our fossil fuels sported extraordinarily high EROIs—100:1 in some cases—we could afford to take this sort of hit on our food-based energy supply. Now, however, we can no longer afford to do so. Moreover, the results of this grossly inefficient energy exchange are rising greenhouse gas emissions. By no longer eating meat, we can reduce greenhouse gas emissions by roughly 14%. Importantly, much of this reduction will be in methane and nitrous dioxide, which have very high global warming potential relative to carbon dioxide.
