A carbon tax is a tax levied on the carbon emissions from producing goods and services. Carbon taxes are intended to make visible the hidden social costs of carbon emissions. They are designed to reduce greenhouse gas emissions by essentially increasing the price of fossil fuels. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. When a fossil fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to CO2. Greenhouse gas emissions cause climate change. This negative externality can be reduced by taxing carbon content at any point in the product cycle.
The spark spread is the theoretical gross margin of a gas-fired power plant from selling a unit of electricity, having bought the fuel required to produce this unit of electricity. All other costs must be covered from the spark spread. The term was first coined by Tony West's trading team on the trading floor of National Power Ltd in Swindon, UK during the late 1990s and quickly came into common usage as other traders realised the trading and hedging opportunities.
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO2-equivalent) per unit of comparison. Such units can be for example tonnes CO2-eq per year, per kilogram of protein for consumption, per kilometer travelled, per piece of clothing and so forth. A product's carbon footprint includes the emissions for the entire life cycle. These run from the production along the supply chain to its final consumption and disposal.
The European Union Emissions Trading System is a carbon emission trading scheme which began in 2005 and is intended to lower greenhouse gas emissions in the EU. Cap and trade schemes limit emissions of specified pollutants over an area and allow companies to trade emissions rights within that area. The ETS covers around 45% of the EU's greenhouse gas emissions.
The Multiannual Financial Framework (MFF) of the European Commission, also called the financial perspective, is a seven-year framework regulating its EU annual budget. It is laid down in a unanimously adopted Council Regulation with the consent of the European Parliament. The financial framework sets the maximum amount of spendings in the EU budget each year for broad policy areas ("headings") and fixes an overall annual ceiling on payment and commitment appropriations.
William Dawbney Nordhaus is an American economist. He was a Sterling Professor of Economics at Yale University, best known for his work in economic modeling and climate change, and a co-recipient of the 2018 Nobel Memorial Prize in Economic Sciences. Nordhaus received the prize "for integrating climate change into long-run macroeconomic analysis".
Carbon accounting is a framework of methods to measure and track how much greenhouse gas (GHG) an organization emits. It can also be used to track projects or actions to reduce emissions in sectors such as forestry or renewable energy. Corporations, cities and other groups use these techniques to help limit climate change. Organizations will often set an emissions baseline, create targets for reducing emissions, and track progress towards them. The accounting methods enable them to do this in a more consistent and transparent manner.
A low-carbon economy (LCE) is an economy which absorbs as much greenhouse gas as it emits. Greenhouse gas (GHG) emissions due to human activity are the dominant cause of observed climate change since the mid-20th century. There are many proven approaches for moving to a low-carbon economy, such as encouraging renewable energy transition, energy conservation, electrification of transportation, and carbon capture and storage. An example are zero-carbon cities.
The CRC Energy Efficiency Scheme was a mandatory carbon emissions reduction scheme in the United Kingdom which applied to large energy-intensive organisations in the public and private sectors. It was estimated that the scheme would reduce carbon emissions by 1.2 million tonnes of carbon per year by 2020. In an effort to avoid dangerous climate change, the British Government first committed to cutting UK carbon emissions by 60% by 2050, and in October 2008 increased this commitment to 80%. The scheme has also been credited with driving up demand for energy-efficient goods and services.
The availability and uptake of green electricity in the United Kingdom has increased in the 21st century. There are a number of suppliers offering green electricity in the United Kingdom. In theory these types of tariffs help to lower carbon dioxide emissions by increasing consumer demand for green electricity and encouraging more renewable energy plant to be built. Since Ofgem's 2014 regulations there are now set criteria defining what can be classified as a green source product. As well as holding sufficient guarantee of origin certificates to cover the electricity sold to consumers, suppliers are also required to show additionality by contributing to wider environmental and low carbon funds.
Carbon leakage a concept to quantify an increase in greenhouse gas emissions in one country as a result of an emissions reduction by a second country with stricter climate change mitigation policies. Carbon leakage is one type of spill-over effect. Spill-over effects can be positive or negative; for example, emission reductions policy might lead to technological developments that aid reductions outside of the policy area. Carbon leakage is defined as "the increase in CO2 emissions outside the countries taking domestic mitigation action divided by the reduction in the emissions of these countries." It is expressed as a percentage, and can be greater or less than 100%. There is no consensus over the magnitude of long-term leakage effects.
Carbon emission trading (also called carbon market, emission trading scheme (ETS) or cap and trade) is a type of emissions trading scheme designed for carbon dioxide (CO2) and other greenhouse gases (GHGs). It is a form of carbon pricing. Its purpose is to limit climate change by creating a market with limited allowances for emissions. This can reduce the competitiveness of fossil fuels, and instead accelerate investments into renewable energy, such as wind power and solar power. Fossil fuels are the main driver for climate change. They account for 89% of all CO2 emissions and 68% of all GHG emissions.
An eco-tariff, also known as an environmental tariff or carbon tariff, is a trade barrier for the purpose of reducing pollution and improving the environment. These trade barriers may take the form of import or export taxes on products that have a large carbon footprint or are imported from countries with lax environmental regulations. The EU Carbon Border Adjustment Mechanism is a carbon tariff.
A low-carbon fuel standard (LCFS) is an emissions trading rule designed to reduce the average carbon intensity of transportation fuels in a given jurisdiction, as compared to conventional petroleum fuels, such as gasoline and diesel. The most common methods for reducing transportation carbon emissions are supplying electricity to electric vehicles, supplying hydrogen fuel to fuel cell vehicles and blending biofuels, such as ethanol, biodiesel, renewable diesel, and renewable natural gas into fossil fuels. The main purpose of a low-carbon fuel standard is to decrease carbon dioxide emissions associated with vehicles powered by various types of internal combustion engines while also considering the entire life cycle, in order to reduce the carbon footprint of transportation.
A world taxation system or global tax is a hypothetical system for the collection of taxes by a central international revenue service. The idea has garnered currency as a means of eliminating tax avoidance and tax competition; it has also aroused the ire of nationalists as an infringement upon national sovereignty.
Zero-carbon housing is housing that does not emit greenhouse gasses (GHGs) into the atmosphere, either directly, or indirectly due to consumption electricity produced using fossil fuels. Most commonly zero-carbon housing is taken to mean zero emissions of carbon dioxide, which is the main climate pollutant from homes, although fugitive methane may also be emitted from natural gas pipes and appliances.
Coal, cars and lorries vent more than a third of Turkey's six hundred million tonnes of annual greenhouse gas emissions, which are mostly carbon dioxide and part of the cause of climate change in Turkey. The nation's coal-fired power stations emit the most carbon dioxide, and other significant sources are road vehicles running on petrol or diesel. After coal and oil the third most polluting fuel is fossil gas; which is burnt in Turkey's gas-fired power stations, homes and workplaces. Much methane is belched by livestock; cows alone produce half of the greenhouse gas from agriculture in Turkey.
The European Green Deal, approved in 2020, is a set of policy initiatives by the European Commission with the overarching aim of making the European Union (EU) climate neutral in 2050. The plan is to review each existing law on its climate merits, and also introduce new legislation on the circular economy (CE), building renovation, biodiversity, farming and innovation.
The Carbon Border Adjustment Mechanism (CBAM) is a carbon tariff on carbon intensive products, such as steel, cement and some electricity, imported to the European Union. Legislated as part of the European Green Deal, it takes effect in 2026, with reporting starting in 2023. CBAM was passed by the European Parliament with 450 votes for, 115 against, and 55 abstentions and the Council of the EU with 24 countries in favour. It entered into force on 17 May 2023.
A climate club is a coalition of the willing among countries that wish to adopt more stringent climate mitigation policies.
