Emissions Trading Mode in America and China and Its Future

The emissions trading is a kind of sustainable development measures that is based on market mechanism, and its growing is closely connected with the market development level. The level of American emissions permits market is relatively high, and also predicts the prospect of professional bourse pattern. Most of emissions permits transactions in China are organized by government environment authority, which make it lack of market function. Emissions permits is a kind of property rights. It is important and profitable, while the emissions trading market obviously possesses the two-class of original allocation and second-time transfer. But there are some decisive differences between emissions permits and ordinary transaction object, so the specialized bourse for emissions trading should be built.     

The optimal initial allocation of pollution permits: a relative performance approach

The initial allocation of pollution permits is an important aspect of emissions trading schemes. We generalize the analysis of Böhringer and Lange (2005, Eur Econ Rev 49(8): 2041–2055) to initial allocation mechanisms that are based on inter-firm relative performance comparisons (including grandfathering and auctions, as well as novel mechanisms). We show that using firms’ historical output for allocating permits is never optimal in a dynamic permit market setting, while using firms’ historical emissions is optimal only in closed trading systems and only for a narrow class of allocation mechanisms. Instead, it is possible to achieve social optimality by allocating permits based only on an external factor, which is independent of output and emissions. We then outline sufficient conditions for a socially optimal relative performance mechanism.     

The effectiveness of anti-leakage policies in the European Union: results for Austria

With the third trading period of the EU emissions trading scheme (EU ETS) starting in 2013, the system of allocating emission allowances will significantly change: In contrast to the previous two trading periods, auctioning of the allowances should now be the rule rather than the exception. Accompanying this policy change, concerns over competitiveness of energy intensive, trade exposed sectors as well as over limited environmental effectiveness via the channel of carbon leakage, have regained prominence. In this paper, we thus explore the impacts of potential EU policies to counter losses in international competitiveness and carbon leakage from the perspective of Austria. Based on numerical simulations with a computable general equilibrium model, we evaluate three policy options: an input subsidy for carbon allowances (thus reflecting the planned partially free allocation mechanism in the third EU ETS phase), a subsidy for domestic production, and an export rebate based on sectoral CO₂ costs. Our results show that each policy has the potential to support domestic production in exposed sectors relative to a full auctioning scenario and thus increase competitiveness. However, none is imperatively effective at reducing Austria’s net carbon emissions: while the carbon trade balance is improved and hence leakage declines, the tradability of emission permits within the EU ETS allows CO₂ emissions from Austria’s ETS output to increase. A cost benefit analysis indicates that the two policies promoting domestic output and exports are more cost effective than the CO₂ input subsidy.     

排污权交易政策对企业环保行为的传导机制研究

从企业的目标函数和生产函数两个角度出发,分析了排污权交易政策对企业环保行为的影响机理,并讨论了排污权交易政策下企业的环保行为选择。研究发现：排污权交易政策通过影响企业的资本要素分配,从而影响企业环境资源的使用成本,进而影响企业的生产和环保行为决策;在排污权交易政策的作用下,企业主要采取不同的污染治理投资策略来满足该政策的规制。基于此,政府应制定配套政策和措施,引导企业沿着“政策遵从—环保投资策略—新环保技术采纳”的行为选择路径进行行为决策,以实现排污权交易政策的目标。     

Alternative standards and instruments for air pollution control in Poland

Like other Central European countries, Poland faces the twin challenges of improving environmental quality while also fostering sustainable economic development. In this study we examine the costs of different standards for air pollution control, and the cost savings from using incentive-based policy instruments in lieu of more rigid command-and-control policies. The comparisons are based on the results of a simulation model of energy use and air pollution control for the Polish economy over 1990–2015. The model simulates least-cost energy supply decisions under different environmental policy assumptions, the corresponding emissions, and the cost of achieving the specified policy objectives. The model results suggest that incentive-based policies will have efficiency gains over command policies that are at least worthy of consideration and may be quite substantial. The size of the gains in practice depends in part on how much flexibility is built into the command approach, e.g., capacity for intrafirm trading as well as alack of technology-specific requirements. To achieve these gains, an increase in the current levels of emissions fees is desirable both to strengthen abatement incentives and to improve the capacity of the Polish government to overcome past environmental damages. However, it seems highly unlikely in practice that fees could be raised to the levels necessary to meet current Polish emissions standards. To make further headway, an evolutionary approach to emissions trading patterned after (and profiting from the experience with) emissions trading in the U.S. seems useful. The program could start out relatively modestly and increase in ambitiousness as the Polish economic transition proceeds.     

Allowing for Household Preferences in Emission Trading – A Contribution to the Climate Policy Debate

In the context of emission trading it seems to be taken as given that people's preferences can be ignored with respect to the whole process of fixing emission targets and allocating emission permits to polluters. With this paper we want to reopen the debate on how citizens can be involved in this process. We try to show how citizen preferences can be included in the process of pollution control through emission trading. We propose an emission trading system where all emission permits are initially allocated to households who are then allowed to sell them in the permit market or to withhold (at least some of) them in order to reduce total pollution. This proposal tries to overcome the fundamental disadvantage of traditional permit systems which neglect consumer preferences by solely distributing emission permits to producers / polluters. In our system the property right to nature is re-allocated to the households who obtain the opportunity of reducing actual emissions according to their personal preferences by withholding a part or all of the emission permits allotted to them. Such a change in environmental policy would mark a return to the traditional principles of consumer sovereignty by involving households (at least partially) in the social abatement decision process instead of excluding them. Another advantage of admitting households to the TEP market as sellers or buyers of permits is that this increases the number of agents in the permit market and thus significantly reduces the possibilities of strategic market manipulations.     

Permit Trading and Credit Trading: A Comparison of Cap-Based and Rate-Based Emissions Trading Under Perfect and Imperfect Competition

This paper compares emissions trading based on a cap on total emissions (permit trading) and on relative standards per unit of output (credit trading). Two types of market structure are considered: perfect competition and Cournot oligopoly. We find that output, abatement costs and the number of firms are higher under credit trading. Allowing trade between permit-trading and credit-trading sectors may increase welfare. With perfect competition, permit trading always leads to higher welfare than credit trading. With imperfect competition, credit trading may outperform permit trading. Environmental policy can lead to exit, but also to entry of firms. Entry and exit have a profound impact on the performance of the schemes, especially under imperfect competition. We find that it may be impossible to implement certain levels of total industry emissions. Under credit trading several levels of the relative standard can achieve the same total level of emissions.     

Cross-Industry Emission Permits Trading

The present paper examines the effectiveness of emission permits trading across industries. We find that, while permits trading in a competitive environment minimizes costs of compliance, it also enhances product market imperfections. We also find that a standard-setting regulation yields superior welfare results if policy makers have able information. Standard setting allows policy makers the flexibility of taking into account the existing imperfections in each industry. Although not surprising, this result has important policy implications in situations in which policy makers consider establishing permits trading between publicly owned dominant polluters and other industrial polluters. Since policy makers have able information on publicly-owned firms, it might be welfare improving to directly control emissions of the dominant publicly-owned polluters. Given that many of the major polluters in the real world are large firms in heavily concentrated industries many of which are also regulated, our result warrants policy makers' attention.

Trading Sulphur Emissions in Europe: `Guided Bilateral Trade'

In this paper a system of `guided permit trading' is developed for SO₂emissions reduction which considers permit trading as a bilateral andsequential process. This implies that in order to meet the deposition targetsat the end of the trading process, not every single trade transaction hasto meet the deposition targets. To ensure that the target is ultimately met,the number of permits traded should be controlled by a trade coordinatinginstitution. A simulation of the system of guided bilateral trading ofSO₂ permits among European countries on the basis of the SecondSO₂ Protocol indicates that some non-profitable trade transactionstake place. This prevents the cost effective emission allocation from beingfully achieved. However, the calculations show that guided bilateral permittrading may generate substantial cost savings while contributing toenvironmental protection.     

Opportunity Cost for Free Allocations of Emissions Permits: An Experimental Analysis

An important feature of emissions trading is how emissions permits are allocated. The choice between an auction and free allocation should not influence firms’ production choices nor consumer prices according to economic theory. However, many parties expect the method of allocation to affect product prices. This paper describes an experimental investigation into price determination under a cap-and-trade program with different allocation methods. Participants initially display diverse pricing strategies. However, given a simple economic setting in which earnings depend on behavior, we find that subjects learn to consider the opportunity cost of permits and overall behavior moves toward the economic prediction.     

Economic Implications of Alternative Allocation Schemes for Emission Allowances*

For reasons of political feasibility, emission trading systems may have to rely on free initial allocation of emission allowances in order to ameliorate adverse production and employment effects in dirty industries. Against the background of an emerging European‐wide emission trading system, we examine the trade‐off between such compensation and economic efficiency under output‐based and emissions‐based allocation rules. We show that the emissions‐based allocation rule is more costly than the output‐based rule in terms of maintaining output and employment in energy‐intensive industries. When the international allowance price increases, the inferiority of emissions‐based allocation vis‐à‐vis output‐based allocation becomes more pronounced, as emission subsidies drastically restrict efficiency gains from international trade in emission allowances.     

Emissions Trading and Profitability: The Swedish Pulp and Paper Industry

The purpose of this paper is to develop models with and without potential emissions trading and to compare industry profits under the two regimes. The model in which emissions trading is permitted is a nonparametric industry frontier model in the spirit of Färe et al. (1992). It is relative to this model that industry profit is computed. This profit is compared to the profit without emissions trading to give an estimate of the potential gains that can be realised by allowing for emissions trading. The model, which is applied to data for the Swedish pulp and paper industry, suggests that this industry would have had up to 6% (1%) higher profits in 1989 (1990) if emissions trading had been used instead of individual permits to achieve the same total emissions target. Currently there is no permit trading in this industry so our results only model the potential gains that can be made.     

On Emissions Trading and Market Structure: Cap-and-Trade versus Intensity Standards

This paper examines the interdependence between imperfect competition and emissions trading. We particularly analyze the long run equilibrium in a two-sector (‘clean’ and ‘dirty’) model with Cournot competition among firms who face a fixed cost of production. The clean sector is defined as the sector with the highest long run cost margin on emissions. We compare the welfare implications of a cap-and-trade scheme with an emissions trading scheme based on relative intensity standards. It is shown that a firm’s long run equilibrium output in the clean or dirty sector does not depend on the emissions trading format, but only depends on the fixed cost of producing in the respective sector. Intensity standards can result in clean firms selling allowances to dirty firms, or dirty firms selling to clean firms. The former outcome yields higher welfare. It is demonstrated that cap-and-trade outperforms the intensity-based trading scheme in terms of long run welfare with free entry and exit. With intensity standards the size of the clean sector is too large.     

Towards a sustainable and efficient use of manure in agriculture: The Dutch case

Rapid increases in livestock production in the Netherlands have changed manure from a valuable input into a mere waste product. This is especially true for the southern and eastern parts of the country, where specialized pig and poultry farms have concentrated on sandy soils. As these farms generally own very little land, they largely depend on imported feedstuffs. As a consequence, manure is applied to the land in such large quantities that serious environmental problems have resulted: (1) eutrophication of surface water by phosphate emissions; (2) pollution of groundwater by nitrate emissions; and (3) acidification by ammonia emissions.In the last few years the Dutch government has developed a manure policy to counteract these effects. Our analysis of that policy has revealed at least three fundamental defects, which render the manure policy ineffective and inefficient. In this paper proposals are made to remove the defects in current manure policy. Much attention is paid to the problem of designing a mixture of policy instruments which is both effective as well as efficient in limiting the environmental problems caused by manure. It is shown that the use of financial incentives in regulation can substantially improve the efficiency of the manure policy. Finally, the main economic consequences of the proposed policy are examined for the public sector as well as for the agricultural sector.     

What to expect from an international system of tradable permits for carbon emissions

We use an econometrically-estimated multi-region, multi-sector general equilibrium model of the world economy to examine the effects of using a system of internationally-tradable emissions permits to control world carbon dioxide emissions. We focus, in particular, on the effects of the system on flows of trade and international capital. Our results show that international trade and capital flows significantly alter projections of the domestic effects of emissions mitigation policy, compared with analyses that ignore international capital flows, and that under some systems of international permit trading the United States is likely to become a significant permit seller, the opposite of the conventional wisdom.     

Climate Policy,Learning, and Technology Adoption in Small Countries

A significant reduction in global greenhouse gas emissions requires international cooperation in emission abatement as well as individual countries’ investment in the adoption of abatement technology. The existing literature on climate policy pays insufficient attention to small countries, which account for a substantial proportion of global emission. In this study, we investigate how climate policy and learning about climate damage affect investment in abatement technology in small countries. We consider three alternative climate policy instruments: emission standards, harmonized taxes and auctioned permits. We say that learning is feasible if an international environmental agreement (IEA) is formed after the resolution of uncertainty about climate damage. We find that, either with learning and quadratic abatement costs or without learning, harmonized taxes outperform emission standards and auctioned permits in terms of investment efficiency. Without learning, a large cost of nonparticipation (that a country incurs) in the IEA can be beneficial to the country. Whether learning improves investment efficiency depends on the size of this nonparticipation cost.     

污染物减排政策效果比较——基于经济学视角

我国政府已经把减少污染物排放作为约束性指标纳入到国家中长期发展战略之中,采取有效的污染物减排政策是中国缓解环境压力、实现经济社会可持续发展的重要手段.排污权交易制度是在总量管制的情况下,通过污染物排放权的分配,最终实现该区域总的排污量削减.本文从经济学的视角,研究了排污权交易的实施基础,并与行政强制性减排以及环境税减排进行了效率比较,结果表明排污权交易比单纯的行政强制性排污和环境税约束具有更高的市场效率以及灵活性,同时并不会降低整个社会的污染物排放效果.此外,从市场势力的影响、市场信息的影响、交易规则的影响等方面讨论了影响排污权交易市场效率的因素,对我国排污权交易市场的发展提出了相应的建议,为排污权交易市场的稳定运行提供了理论参考.

The Cost-Effective Choice of Policy Instruments to Cap Aggregate Emissions with Costly Enforcement

We study the cost-effectiveness of inducing compliance in a program that caps aggregate emissions of a given pollutant from a set of heterogeneous firms based on emissions standards and the relative cost-effectiveness of such a program with respect to an optimally designed program based on tradable discharge permits. Our analysis considers abatement, monitoring and sanctioning costs, as well as perfect and imperfect information on the part of the regulator with regard to the polluters’ abatement costs. Under perfect information we find that (a) the total-cost-effective design of a program based on standards is one in which the standards are firm specific and perfectly enforced, and (b) the total cost of an optimally designed program based on standards is lower than the total cost of an optimally designed transferable emission permits system, except under special conditions. This is true when it is optimum to induce perfect compliance and when it is not. Under imperfect information, nevertheless, it is only by implementing a system of tradable permits and perfectly enforcing it with a constant marginal penalty tied to the price of the permits, that the regulator can surmount the informational problem and at the same time minimize the total cost of the program with certainty.
