Cap And Share
Cap and Share was originally developed by Feasta (the Foundation for the Economics of Sustainability). It is a regulatory and economic framework for controlling the use of fossil fuels in relation to climate stabilisation. Convinced that climate change is a global problem and that there is a need to cap and reduce greenhouse gas emissions globally, the philosophy of Cap and Share maintains that the earth’s atmosphere is a fundamental common resource. Consequently, it is argued, each individual should get an equal share of the benefits from the limited amount of fossil fuels that will have to be burned and their emissions released into the atmosphere in the period until the atmospheric concentration of greenhouse gases has been stabilised at a safe level. Design This market based mechanism was devised by Feasta in 2005 and 2006, and they have set out the case for the introduction of Cap and Share globally in policy documents.The Foundation for the Economics of Sustainability, ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

Pigovian Tax
A Pigouvian tax (also spelled Pigovian tax) is a tax on any market activity that generates negative externalities (i.e., external costs incurred by the producer that are not included in the market price). The tax is normally set by the government to correct an undesirable or inefficient market outcome (a market failure), and does so by being set equal to the external marginal cost of the negative externalities. In the presence of negative externalities, social cost includes private cost and external cost caused by negative externalities. This means the social cost of a market activity is not covered by the private cost of the activity. In such a case, the market outcome is not efficient and may lead to over-consumption of the product. Often-cited examples of negative externalities are environmental pollution and increased public healthcare costs associated with tobacco and sugary drink consumption.. In the presence of positive externalities (i.e., external public benefits gaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Carbon Trading
Carbon rationing, as a means of reducing CO2 emissions to contain climate change, could take any of several forms. One of them, personal carbon trading, is the generic term for a number of proposed emissions trading schemes under which emissions credits would be allocated to adult individuals on a (broadly) equal per capita basis, within national carbon budgets. Individuals then surrender these credits when buying fuel or electricity. Individuals wanting or needing to emit at a level above that permitted by their initial allocation would be able to purchase additional credits in the personal carbon market from those using less, creating a profit for those individuals who emit at a level below that permitted by their initial allocation. Some forms of personal carbon trading (carbon rationing) could be an effective component of climate change mitigation, with the economic recovery of COVID-19 and new technical capacity having opened a favorable window of opportunity for initial te ...

Greenhouse Development Rights
Greenhouse Development Rights (GDRs) is a justice-based effort-sharing framework designed to show how the costs of rapid climate stabilization can be shared fairly, among all countries. More precisely, GDRs seeks to transparently calculate national “fair shares” in the costs of an emergency global climate mobilization, in a manner that takes explicit account of the fact that, as things now stand, global political and economic life is divided along both North/South and rich/poor lines. Critically, GDRs approaches climate protection and economic development as two sides of one coin. Its goal is developmental justice, as it might exist even in a world that is compelled to rapidly reduce greenhouse-gas emissions to near-zero levels. The GDRs analysis suggests that rapid climate stabilization will prove impossible without an extremely strong commitment – a right – to a dignified level of sustainable human development (humanity). A right to life free from the privations of pover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georgism
Georgism, also called in modern times Geoism, and known historically as the single tax movement, is an economic ideology holding that, although people should own the value they produce themselves, the economic rent derived from land—including from all natural resources, the commons, and urban locations—should belong equally to all members of society. Developed from the writings of American economist and social reformer Henry George, the Georgist paradigm seeks solutions to social and ecological problems, based on principles of land rights and public finance which attempt to integrate economic efficiency with social justice. Georgism is concerned with the distribution of economic rent caused by land ownership, natural monopolies, pollution rights, and control of the commons, including title of ownership for natural resources and other contrived privileges (e.g. intellectual property). Any natural resource which is inherently limited in supply can generate economic rent, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emissions Trading
Emissions trading is a market-based approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants. The concept is also known as cap and trade (CAT) or emissions trading scheme (ETS). Carbon emission trading for and other greenhouse gases has been introduced in China, the European Union and other countries as a key tool for climate change mitigation. Other schemes include sulfur dioxide and other pollutants. In an emissions trading scheme, a central authority or governmental body allocates or sells a limited number (a "cap") of permits that allow a discharge of a specific quantity of a specific pollutant over a set time period. Polluters are required to hold permits in amount equal to their emissions. Polluters that want to increase their emissions must buy permits from others willing to sell them. Emissions trading is a type of flexible environmental regulation that allows organizations and markets to decide how best to meet policy t ...

Emissions Reduction Currency System
Emissions Reduction Currency Systems (ERCS) are schemes that provide a positive economic and or social reward for reductions in greenhouse gas emissions, either through distribution or redistribution of national currency or through the publishing of coupons, reward points, local currency, or complementary currency. Compared to other emissions reductions instruments Emissions reduction currency is different from an emissions credit. The value of an emissions credit is determined by a national cap in emissions and the degree to which the credit confers a right to pollute. The ultimate value of an emissions credit is realised when it is surrendered to avoid punitive fines for emitting. Emissions reduction currency is also different from a voluntary carbon offset where a payment is made, typically to fund alternative energy or reforestation, the emissions reduction or sequestration resulting from which is used to reduce or cancel the payers responsibility for emissions produced by t ...

Economics Of Global Warming
The economics of climate change concerns the economic aspects of climate change; this can inform policies that governments might consider in response. A number of factors make this and the politics of climate change a difficult problem: it is a long-term, intergenerational problem; (pb: benefits and costs are distributed unequally both within and across countries; and both the scientific consensus and public opinion on climate change need to be taken into account. Effects of climate change may last a long time, such as sea level rise which will not be reversed for thousands of years. The long time scales and uncertainty associated with global warming have led analysts to develop " scenarios" of future environmental, social and economic changes. These scenarios can help governments understand the potential consequences of their decisions. One of the responses to the uncertainties of global warming is to adopt a strategy of sequential decision making. This strategy recognizes tha ...

Carbon Tax
A carbon tax is a tax levied on the carbon emissions required to produce goods and services. Carbon taxes are intended to make visible the "hidden" social costs of carbon emissions, which are otherwise felt only in indirect ways like more severe weather events. In this way, they are designed to reduce carbon dioxide ( ) emissions by increasing prices of the fossil fuels that emit them when burned. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. In its simplest form, a carbon tax covers only CO2 emissions; however, it could also cover other greenhouse gases, such as methane or nitrous oxide, by taxing such emissions based on their CO2-equivalent global warming potential. When a hydrocarbon fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to . Greenhouse gas emissions cause climate change, which damages the environment and human health. This negative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cap And Dividend
Cap and dividend is a market-based trading system which retains the original capping method of cap and trade, but also includes compensation for energy consumers. This compensation is to offset the cost of products produced by companies that raise prices to consumers as a result of this policy. The process begins with some governments setting aggregate pollution quotas (e.g., for carbon emissions) and selling pollution permits to the public respectively. Polluters are required to buy those credits to match their pollution outputs. Some of the cost producers pay for pollution will result in higher costs for consumers, who as citizens are additionally faced with the environmental costs of the pollution. Under the cap and dividend system, public revenues raised from the sale of pollution credits is rebated to citizens or to consumers as a subsidy for increasing efficiency. Overview The goal of this type of pseudo-tax is to reduce carbon emission rates. This is similar to the cap-an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
