Emissionsrechtehandel

Emissionsrechtehandel

Emissionsrechtehandel, also known as emissions trading or cap-and-trade, is a market-based instrument within Environmental Finance designed to control pollution by providing economic incentives for reducing pollutant emissions. It operates on the principle of establishing a limit, or "cap," on the total amount of specific pollutants that can be emitted by a group of sources. Within this cap, participants are allocated or can buy and sell emissions allowances, each representing the right to emit a certain quantity of a pollutant. This system creates a compliance market where the allowances become a valuable financial instrument.

History and Origin

The concept of emissions trading has roots in the 1960s with discussions around market-based approaches to environmental protection. However, its significant international adoption began with the 1997 Kyoto Protocol, an international treaty under the United Nations Framework Convention on Climate Change (UNFCCC). The Kyoto Protocol established three market-based mechanisms, including an international emissions trading mechanism, to help industrialized countries meet their greenhouse gas reduction targets. This marked the creation of what is now known as the carbon market²¹, ²².

Building on this, the European Union (EU) launched the world's first large multi-national greenhouse gas emissions trading scheme, the EU Emissions Trading System (EU ETS), in 2005. It was established as a cornerstone of the EU's climate policy to tackle climate change and cost-effectively reduce emissions¹⁹, ²⁰. The EU ETS, a prominent example of a cap and trade system, initially covered major energy-intensive sectors and has since expanded its scope to include aviation and, more recently, maritime transport¹⁷, ¹⁸.

Key Takeaways

• Emissionsrechtehandel is a market-based approach to environmental regulation that sets a limit on total emissions and allows entities to trade emission allowances.
• It aims to reduce pollution, particularly greenhouse gases, cost-effectively by creating a price for emissions.
• The system operates on the principles of supply and demand for emission allowances, influencing their market price.
• Major systems like the EU ETS demonstrate its application in achieving climate targets.
• Participants are required to monitor and report their emissions and surrender enough allowances to cover their annual output.

Interpreting the Emissionsrechtehandel

The effectiveness of an Emissionsrechtehandel system is largely gauged by its ability to drive down emissions and foster innovation in cleaner technologies. The price of an emission allowance in the market reflects the cost of polluting, providing a clear signal to businesses. A higher price generally indicates a stronger incentive to reduce emissions. This market-driven approach aims to achieve emission reductions where it is most cost-efficient, allowing for flexible compliance. Entities facing high abatement costs may choose to buy allowances, while those that can reduce emissions cheaply can sell their surplus, benefiting from the market mechanism¹⁶. The dynamics of price volatility in allowance prices can influence investment decisions in emission reduction technologies.

Hypothetical Example

Imagine "Company Alpha" and "Company Beta" are two industrial firms operating under an Emissionsrechtehandel system. The regulator sets a total cap for the industry and initially allocates 100 carbon credits to each company, with each credit permitting one tonne of CO2 equivalent emissions.

Company Alpha invests in new, energy-efficient machinery and manages to reduce its emissions to 70 tonnes. It now has 30 surplus credits. Company Beta, facing higher costs for abatement, emits 120 tonnes. To comply with the regulation, Company Beta needs an additional 20 credits.

In this scenario, Company Alpha can sell 20 of its surplus credits to Company Beta. Both companies benefit: Company Alpha earns revenue from selling its unused allowances, offsetting its investment in efficiency, while Company Beta avoids penalties by purchasing the necessary credits, achieving compliance at a potentially lower cost than if it had to implement expensive internal reductions. This transaction exemplifies the core function of emissions trading, where the price of the credits is determined on commodity markets through trading.

Practical Applications

Emissionsrechtehandel is primarily applied as a tool in public policy for climate change mitigation. Beyond the well-known EU ETS, similar systems operate in various jurisdictions worldwide, including parts of the United States (like California's Cap-and-Trade Program), China, and Canada¹⁵. These systems typically cover emissions from large industrial installations, power generation, and increasingly, other sectors like transport and buildings¹³, ¹⁴.

Companies participating in these schemes integrate the cost of allowances into their business models, influencing investment in research and development for low-carbon technologies. The revenues generated from the auctioning of allowances by governments are often earmarked to finance the green transition, supporting investments in renewable energy and energy efficiency improvements¹¹, ¹². Such systems encourage industries to explore new offsetting projects and other avenues for emission reduction.

Limitations and Criticisms

Despite its widespread adoption, Emissionsrechtehandel faces several limitations and criticisms. One common concern is the potential for "carbon leakage," where industries might relocate to regions with less stringent emission regulations to avoid compliance costs, leading to no net global reduction in emissions. Another criticism revolves around the initial allocation of allowances; if too many allowances are distributed, it can lead to a low carbon price, weakening the incentive for emissions reduction¹⁰.

Concerns have also been raised regarding the market efficiency and integrity of carbon markets. Issues such as the potential for over-crediting in voluntary markets or allegations of "greenwashing" can undermine public trust and the environmental effectiveness of the system⁸, ⁹. Some argue that while the system aims for cost-effectiveness, the actual reduction in emissions may not be as significant as desired, or it might disproportionately affect certain industries or consumers if not carefully designed. The complexity of derivatives used in carbon markets also raises concerns about transparency and potential for manipulation.

Emissionsrechtehandel vs. Carbon Tax

Emissionsrechtehandel is often compared with a carbon tax, another market-based approach to climate policy. The primary distinction lies in what each mechanism fixes and what it allows to fluctuate.

While Emissionsrechtehandel provides certainty over emission reduction targets, a carbon tax offers price certainty for businesses, making it easier to forecast costs. Both instruments aim to internalize the external cost of pollution, creating incentives for polluters to reduce their environmental impact⁵, ⁶, ⁷.

FAQs

How does Emissionsrechtehandel help reduce pollution?

It sets a legally binding limit (cap) on the total amount of pollution allowed. Companies that emit less than their allocated amount can sell their excess allowances, creating a financial incentive to reduce emissions. Conversely, companies that exceed their limit must buy additional allowances or face penalties, making pollution more expensive.

What are carbon allowances or credits?

Carbon credits or allowances are tradable permits, each representing the right to emit one tonne of carbon dioxide equivalent (CO2e) greenhouse gases. They are the currency of emissions trading systems.⁴

Who participates in Emissionsrechtehandel systems?

Typically, large industrial emitters, power generators, and increasingly, sectors like aviation and maritime transport, are mandated to participate. Some systems also include voluntary participants or mechanisms for project-based credits.³

Are all emission allowances given for free?

No. While some early systems or specific industries might have received a portion of allowances for free (known as "grandfathering"), most modern Emissionsrechtehandel systems increasingly use auctions as the primary method for distributing allowances. This ensures the "polluter pays" principle is applied and generates revenue that can be reinvested into climate action.¹, ²
