Credits are gained by investing in clean technologies and low-carbon solutions, and by certain types of emission-saving projects around the world to cover a proportion of their emissions. Cap and trade's purpose is to create a market price for emissions or pollutants that did not previously exist and address possible negative externalities. Permits are issued to emitters and operating without a permit is against the law. The burden of a volatile market thus lies with the industry rather than the controlling agency, which is generally more efficient. It is a policy move aimed at controlling large amounts of gas emissions from a cluster of sources. Pollution is the prime example of a market externality. It is possible to implement such systems in subgame perfect equilibrium.
How cap and trade works. The system reduces emissions by setting a limit on pollution and creating a market. Cap and trade is a powerful approach to reducing pollution in our atmosphere. It’s our best shot, environmentally and economically, for curbing emissions that drive global warming.
What is 'Cap And Trade'?
Companies in Quebec can also buy permits from companies in California and vice versa. The benefit of this is that it should create a more stable carbon price over time, because so many more companies are participating. The government gives out some permits for free, usually to companies in sectors that are vulnerable to competitors in other jurisdictions without cap-and-trade systems. One example is the aluminium industry in Quebec, which faces stiff competition around the world.
The rationale is that these companies should not face a disadvantage — and therefore be tempted to relocate — by doing business in a jurisdiction with cap and trade. The government can also auction off some of the carbon permits, which helps set a price for them and raises money for government. The government is promising to direct this money into other environmental projects — new public transit lines, for instance. Whether they keep this pledge remains to be seen. Under a carbon tax, the government simply sets a price on carbon and everyone who buys a product that creates emissions must pay it.
In theory, people will cut their carbon use over time to avoid paying the tax. The advantage of a carbon tax, compared with cap and trade, is that it is relatively easy to administer and straightforward to understand. Everyone pays the same price to burn carbon. The downside to a carbon tax is that it does not set an exact cap on emissions.
The government just sets the price and hopes that consumer behaviour will do the rest. Cap and trade, on the other hand, allows government to mandate the exact reductions it wants to see. But there is a downside.
Cap and trade is a lot more complicated than a carbon tax, and can be gamed by industry. For example, if companies over-report the amount of carbon they are burning to begin with, government could set the caps too high and not actually achieve significant reductions.
The allocation of permits also allows government to pick winners and losers: There is also a transparency issue. Under a carbon tax, everyone knows more or less what they are paying. Under cap and trade, companies will likely pass the cost to consumers, but it may not be clear exactly what those costs could be. Goldsmith of San Francisco's Superior Court stated that the rules governing California's cap-and-trade system were adopted without a proper analysis of alternative methods to reduce greenhouse gas emissions.
If the decision is made final, the state would not be allowed to implement its proposed cap-and-trade system until the California Air Resources Board fully complies with the California Environmental Quality Act. Some of the emitters obtain allowances for free, which is for the electric utilities, industrial facilities and natural gas distributors, whereas some of the others have to go to the auction.
In February , five U. In , the State of Illinois adopted a trading program for volatile organic compounds in most of the Chicago area, called the Emissions Reduction Market System. Waxman and Edward J. South Korea's national emissions trading scheme officially launched on 1 January , covering entities from 23 sectors.
With a three-year cap of 1. This amounts to roughly two-thirds of the country's emissions. In an effort to reverse the adverse consequences of air pollution, in , China started to consider a national pollution permit trading system in order to use market-based mechanisms to incentivize companies to cut pollution.
In , when the Chinese government started considering a national level pollution permit trading system again, there were more than 20 local pollution permit trading platforms. The Yangtze River Delta region as a whole has also run test trading, but the scale was limited. When the market launched, it will be the largest carbon market in the world. The initial design of the system targets a scope of 3. In November , China approved pilot tests of carbon trading in seven provinces and cities — Beijing, Chongqing, Shanghai, Shenzhen, Tianjin as well as Guangdong Province and Hubei Province, with different prices in each region.
Their successes or failures will, therefore, have far-reaching implications for carbon market development in China in terms of trust in a national carbon trading market. The effort to start a national trading system has faced some problems that took longer than expected to solve, mainly in the complicated process of initial data collection to determine the base level of pollution emission.
Trading is set to begin in after a three-year rollout period. India has pledged a 20 to 25 per cent reduction in emissions intensity from levels by Under the scheme, annual efficiency targets will be allocated to firms.
Tradable energy-saving permits will be issued depending on the amount of energy saved during a target year.
Renewable Energy Certificates occasionally referred to as or "green tags" [citation required] , are a largely unrelated form of market-based instruments that are used to achieve renewable energy targets, which may be environmentally motivated like emissions reduction targets , but may also be motivated by other aims, such as energy security or industrial policy. Carbon emissions trading is emissions trading specifically for carbon dioxide calculated in tonnes of carbon dioxide equivalent or tCO 2 e and currently makes up the bulk of emissions trading.
It is one of the ways countries can meet their obligations under the Kyoto Protocol to reduce carbon emissions and thereby mitigate global warming. Trading can be done directly between buyers and sellers, through several organised exchanges or through the many intermediaries active in the carbon market.
The price of allowances is determined by supply and demand. As many as 40 million allowances have been traded per day. In terms of dollars, the World Bank has estimated that the size of the carbon market was 11 billion USD in , 30 billion USD in ,  and 64 billion in The Marrakesh Accords of the Kyoto protocol defined the international trading mechanisms and registries needed to support trading between countries sources can buy or sell allowances on the open market.
Because the total number of allowances is limited by the cap, emission reductions are assured. However, while the USA as a nation did not ratify the Protocol, many of its states are developing cap-and-trade systems and considering ways to link them together, nationally and internationally, to find the lowest costs and improve liquidity of the market.
For example, in contrast to other Kyoto-compliant systems, some states propose other types of greenhouse gas sources, different measurement methods, setting a maximum on the price of allowances, or restricting access to CDM projects. Creating instruments that are not fungible exchangeable could introduce instability and make pricing difficult. Various proposals for linking these systems across markets are being investigated, and this is being coordinated by the International Carbon Action Partnership ICAP.
On June 9, the Group published a statement stating the need to act on climate change and stressing the importance of market-based solutions. It called on governments to establish "clear, transparent, and consistent price signals" through "creation of a long-term policy framework" that would include all major producers of greenhouse gases. Business in the UK have come out strongly in support of emissions trading as a key tool to mitigate climate change, supported by NGOs.
On December 11, , Rex Tillerson , the CEO of Exxonmobil , said a carbon tax is "a more direct, more transparent and more effective approach" than a cap-and-trade program, which he said, "inevitably introduces unnecessary cost and complexity". He also said that he hoped that the revenues from a carbon tax would be used to lower other taxes so as to be revenue neutral.
They argue grandfathering "would penalise airlines that took early action to modernise their fleets, while a benchmarking approach, if designed properly, would reward more efficient operations". Assuring compliance with an emissions trading scheme requires measuring, reporting and verification MRV.
These measurements are reported to a regulator. For greenhouse gases, all trading countries maintain an inventory of emissions at national and installation level; in addition, trading groups within North America maintain inventories at the state level through The Climate Registry.
For trading between regions, these inventories must be consistent, with equivalent units and measurement techniques. In some industrial processes, emissions can be physically measured by inserting sensors and flowmeters in chimneys and stacks, but many types of activity rely on theoretical calculations instead of measurement.
Depending on local legislation, measurements may require additional checks and verification by government or third party auditors , prior or post submission to the local regulator.
A firm might buy a small amount of allowances but emit a much larger amount of pollution. This creates a troublesome moral hazard problem. This problem may be solved by a centralized regulator.
The regulator should perform Measuring, Reporting and Verification MRV of the actual pollution levels, and enforce the allowances. Enforcement methods include fines and sanctions for polluters that have exceeded their allowances. Concerns include the cost of MRV and enforcement, and the risk that facilities may lie about actual emissions. The net effect of a corrupt reporting system or poorly managed or financed regulator may be a discount on emission costs, and a hidden increase in actual emissions.
Based on institutional and enforcement considerations, Kruger et al. An alternative to centralized regulation is distributed regulation, in which the firms themselves are induced to inspect the other firms and report their misbehavior.
It is possible to implement such systems in subgame perfect equilibrium. Moore and Repullo  present an implementation with unbounded fines; Kahana and Mealem and Nitzan  present an implementation with bounded fines. Their work extends the work of Duggan and Roberts  by adding a second component which takes care of the moral hazard. For example, in the popular science magazine New Scientist , Lohmann argued that trading pollution allowances should be avoided as a climate stabilization policy for several reasons.
First, climate change requires more radical changes than previous pollution trading schemes such as the US SO 2 market. It requires reorganizing society and technology to "leave most remaining fossil fuels safely underground". Carbon trading schemes have tended to reward the heaviest polluters with 'windfall profits' when they are granted enough carbon credits to match historic production.
Expensive long-term structural changes will not be made if there are cheaper sources of carbon credits which are often available from less developed countries, where they may be generated by local polluters at the expense of local communities. Research by Preston Teeter and Jorgen Sandberg has shown that the flexibility, and thus complexity, inherent in cap and trade schemes has resulted in a great deal of policy uncertainty surrounding these schemes.
As a result of this uncertainty, organizations have little incentive to innovate and comply, resulting in an ongoing battle of stakeholder contestation for the past two decades.
Lohmann b supported conventional regulation, green taxes, and energy policies that are "justice-based" and "community-driven. Annie Leonard 's documentary The Story of Cap and Trade criticized carbon emissions trading for the free permits to major polluters giving them unjust advantages, cheating in connection with carbon offsets , and as a distraction from the search for other solutions.
Forest campaigner Jutta Kill of European environmental group FERN argued that offsets for emission reductions were not substitute for actual cuts in emissions. Kill stated that "[carbon] in trees is temporary: Trees can easily release carbon into the atmosphere through fire, disease, climatic changes, natural decay and timber harvesting.
Regulatory agencies run the risk of issuing too many emission credits, which can result in a very low price on emission permits. On the other hand, issuing too few permits can result in an excessively high permit price.
However, a price-ceiling safety value removes the certainty of a particular quantity limit of emissions. If polluters receive emission permits for free "grandfathering" , this may be a reason for them not to cut their emissions because if they do they will receive fewer permits in the future. This perverse incentive can be alleviated if permits are auctioned, i. Revenues from auctioning go to the government and can be used for development of sustainable technology  or to cut distortionary taxes, thus improving the efficiency of the overall cap policy.
On the other hand, allocating permits can be used as a measure to protect domestic firms who are internationally exposed to competition. This argument in favor of allocation of permits has been used in the EU ETS, where industries that have been judged to be internationally exposed, e.
This method of distribution may be combined with other forms of allowance distribution. The Bill was found to protect low-income consumers, but it was recommended that the Bill be made more efficient by reducing welfare provisions for corporations, and more resources be made available for consumer relief. Distinct cap-and-trade systems can be linked together through the mutual or unilateral recognition of emissions allowances for compliance.
Linking systems creates a larger carbon market, which can reduce overall compliance costs, increase market liquidity and generate a more stable carbon market. In , the U. In , the provinces of Ontario and Manitoba agreed to join the linked system between Quebec and California. The International Carbon Action Partnership brings together regional, national and sub-national governments and public authorities from around the world to discuss important issues in the design of emissions trading schemes ETS and the way forward to a global carbon market.

While this depends on the specific cap-and-trade program, some examples include producers of the polluting substance, distributors of a product whose production or consumption generates emissions, States, or even nations. How allowances are initially distributed. Allowances could be auctioned, distributed for free based on current or historical emissions, or given out using some combination of an auction and a free distribution. In an auction, allowances are sold to the highest bidders.
Uses of auction revenue depend on the specific cap-and-trade program, and could include the distribution of a portion of the revenue to consumers. Whether the program allows for the purchase of offsets in lieu of allowances.
Offsets are certified reductions in emissions from sources that are not required by the cap-and-trade program to restrict their emissions.
Emitter ABC found it really easy and cheap to reduce its emissions below the level covered by its allowances, while Emitter XYZ had a tougher time. ABC was able to make larger reductions in its emissions and offered to sell its extra allowances to XYZ. This transaction was a good deal for XYZ because the cost of allowances it bought was lower than the cost of equipment needed to reduce its own emissions to a level that matched the number of allowances it held before buying more allowances from ABC.
How much an allowance costs. In general, the allowance price depends on the options available to reduce emissions and the demand for allowances. If there are relatively low-cost options to reduce emissions, the price of allowances would be lower.
Actual emissions are measured and penalties are assessed if targets are missed. Depending on the program, these tasks could be the responsibility of one or more governmental agencies.
The burning of fossil fuels, including coal, oil, and natural gas, is the main source of carbon dioxide — the most important greenhouse gas produced by human activity — and a major source of other emissions. A cap-and-trade program for greenhouse gas emissions would increase the cost of using fossil fuels, making them less competitive with non-fossil energy resources and increasing the overall cost of energy to consumers.
The cost of using coal, which has the highest carbon dioxide content and the lowest price per unit of energy among the fossil fuels, would be most affected by a cap-and-trade program for greenhouse gases. A cap-and-trade program allows emitters to have flexibility in their approach to reducing emissions. An alternative environmental policy might require each regulated source to use a specific emission control technology.
With a cap-and-trade program, the overall cap on emissions is fixed, but the compliance approach by any individual source need not be specified. This flexibility allows parties to choose the least costly option and should reduce the cost of reaching the overall emissions cap. The implementation of the U. Allowances for sulfur dioxide emissions were actively traded as coal-fired electricity generating units covered by the program chose a variety of compliance strategies.
These strategies included installing scrubbers, switching to lower sulfur coal, and buying allowances. Cap-and-trade programs have been used to limit several different types of emissions in State, U.
Carbon Program May Hold Lesson for Other States
Cap-and-trade is environmentally and economically friendly approach to capping and controlling greenhouse gas emissions which is the primary cause of global warming. It is a policy move aimed at controlling large amounts of gas emissions from a cluster of sources. This approach sets an overall cap. How a cap-and-trade system works Critics of all types of carbon pricing say it hits the poor hardest by raising household energy prices. Ontario's first cap-and-trade auction takes place on Wednesday. Here is a basic explanation on how the cap-and-trade system is expected to work. Ontario plunges into cap and trade with first.
