High Quality Content by WIKIPEDIA articles! A zero-carbon city is a settlement powered exclusively by renewable energy sources. To become a zero carbon city, an established modern city must collectively reduce emissions of greenhouse gases to zero and all practices that emit greenhouse gases must cease. Also, renewable energy must supersede other non-renewable energy sources and become the sole source of energy, so a zero-carbon city is a renewable-energy-economy city. This transition which includes decarbonising electricity (increasing the importance of the sources of renewable electricity) and zero-emission transport, is undertaken as a response to climate change and peak oil.
Best Available Technology Not Entailing Excessive Costs (BATNEEC) is a sustainable waste management system that effectively analyses series of methodologies, Best Practicable Environmental Options (BPEO) and their impacts as applicable in solid waste management within the environment to reducing cost, fossil fuels and greenhouse gas emissions as the key performance indicators, in line to ensuring global sustainability of Zero waste tolerance. It's generally known in most developed nations such as EU with recent regulations and practices has given preferences on preventive measures to reduce waste volumes through different processes of management. Similarly, revers is the case when compared with the developing nations. As this research had reveled vast resources through waste disposals yet on taped from Nigerian waste sector, vis-a-vis the sequential quantifications of Nigerian carbon footprint in GHG emission of CO2 and CH4 equivalent in tons.
This study was conducted at Hisar and Karnal district of Haryana, India, to create awareness towards sequestration of greenhouse gases for sustainable agriculture. The 125 farmers were selected and interviewed with the help of well-structured schedule. The majority of the farmers were of middle age group (36-50 years), educated up to matric, belonged to a joint family (5-6 members), performed only farming and had average land holding up to 5 acres. The result shown that farmers' awareness towards greenhouse gases, climate change and global warming were found fully aware as per farmers' responses. Major causes of greenhouse gases were high use of inorganic farm inputs (2.88), intensive tillage practices (2.75) and etc. Very serious losses due to greenhouse gases were crop benefit ratio decreased, crop damaged due to adverse climatic uncertainty. Results pertaining adoption of alternative measures for sequestration of greenhouse gases for sustainable agriculture was medium. Farm practices like the evolution of new crop cultivars, crop diversification, zero tillage and integrated farming practices were found very effective among the farmers to reduce the greenhouse gases emission.
In this modern era, people have become such dependent on motorized transportation that they want to have their private mode of transport for the convenience of their frequent movement. From a recent statistics it is found that currently almost 2.7 million vehicles are running alone on the roads of Bangladesh and approximately 2.4 million are the type of vehicle which is used for personal means. Because of the huge number of vehicles on the road, the fuel consumption is very high and except gas, most of other fuels (octane, petrol, diesel etc.) are imported from abroad. Bangladesh an import-dependent country, with this high demand of fuel, is so now counting loss. Furthermore burning of these fuels causes a huge amount of carbon dioxide (CO2) emission that results greenhouse effect.In this project, the idea of a green bus system is proposed which can be a remarkable aid to the recent traffic condition. In this regard a prototype of green bus system is implemented where resources such as wind, solar and piezo-electric generator are employed. All the resources being used in this project are abundantly available and also emit zero CO2.
It is possible to define zero energy/emission buildings by various aspects.Energy consumption in operation phase of the buildings is the majority discussion in this field.EU s targets regarding climate change and energy for sustainable growth which were approved by European parliament include greenhouse gas emission reduction by 20%,increase in consuming of renewable energy resources by 20% and achieving 20% increase in energy efficiency for moving toward zero energy/emission buildings until 2020.The zero energy/emission buildings are gaining interest as renewable energy resources which help to capture green house gases emission, especially CO2 emission.By considering this fact that residential buildings consume 40% of total delivered energy in Sweden,the scientifically assessment of CO2 level in this country by residential sector on one hand and implementing new technologies for decreasing GHG emission in term of decreasing energy consumption on the other hand are very important. By knowing this fact that for producing 1KWh energy in Sweden around 40g CO2 emission is released,in two million Swedish single family houses it is possible to capture around 800000 tonnes CO2 emission
Due to rapid growth in population and industrialization, there has been a tremendous rise in demand of fossil fuels, coal and gas refineries which simultaneously increases the level of emitted carbon dioxide in the environment resulting in increase of concentration of greenhouse gases causing global warming. To overcome this there is a need to capture carbon dioxide from environment. There are many organisms falling under different-different level to assimilate carbon dioxide as a carbon source which is not only restricted to photosynthetic organisms. At the industrial-scale, many carbon dioxide utilizing microorganism are used extensively. This study focuses onto to capture gaseous carbon dioxide by the microorganism at high temperature and anaerobic conditions. Some Chemotrophs like Clostridium species was studied. These microorganisms uptake atmospheric carbon dioxide and convert into bio-based products. Utilization of emitted carbon dioxide from atmosphere provides a sustainable solution of zero emission platforms.
This book presents a systematic study of methane production and oxidation processes in anoxic soils, using mathematical modelling tools and dynamical systems theory. Methane is a greenhouse gas and the second largest contributor to global warming among anthropogenic greenhouse gases. Methane emission from soil ecosystems is basically regulated by two opposing microbial processes: methane production and methane oxidation. Main topic of the book includes quantification and quantitative analyses of the soil microbial communities and associated biogeochemical processes that release soil carbon as methane gas to the atmosphere. It demonstrates and quantifies different dynamic regimes for a variety of long-term behaviors of methane emissions. It also discusses the roles of potential process-controlling factors and its spatiotemporal variability. Consequently, this study illustrates a "zero-emission" technique to force the emission towards 'zero' at long-term.
The necessity to reduce green house gas emission and growing difficulties in fossil fuel recovery raise great challenges for the scientific community to develop efficient, low cost alternative energy sources. Hydrogen is sought by many as a way to store and transport energy produced from renewable sources. As a fuel hydrogen produces only water on burning and is not toxic in any way. Photolytic processes are very attractive for hydrogen production due to the zero greenhouse gas emissions, however, they can be commercially used only if limitations related to low efficiency and poor stability can be resolved. In this work we describe a novel cell structure for stable photo electrochemical water splitting that can be prepared by electrodeposition from ionic liquids at high temperature. The deposition methods developed here provide low cost and efficient way to synthesise high quality semiconductors and their alloys. The concept presented in this work can potentially be applied to a variety of efficient, yet unstable systems to achieve efficient and long lasting water splitting.
_ Weltweit nehmen die Anforderungen der Gesetzgeber an die Automobilindustrie hinsichtlich der Reduktion von CO 2 -Flottenemissionen und der Markteinführung alternativer Fahrzeugantriebe zu. Jörg Wansart entwickelt ein Simulationswerkzeug für die Analyse von Strategien der Automobilindustrie zur Einhaltung der gesetzlichen Anforderungen bezüglich Greenhouse Gases (GHG) und Zero Emission Vehicles (ZEV) in Kalifornien.
