Introduction
The Emissions Trading Scheme (ETS) is a market-based approach designed to control pollution by providing economic incentives for achieving reductions in the emissions of pollutants, notably greenhouse gases. This system is increasingly used worldwide as part of the strategy to combat climate change.
Historical Context
The concept of emissions trading originated in the late 20th century, drawing upon economic theories of market efficiency to address environmental issues. One of the first significant implementations was the US Acid Rain Program in the 1990s, targeting sulfur dioxide (SO₂) emissions. The success of this program paved the way for more comprehensive schemes addressing carbon dioxide (CO₂) emissions, such as the European Union Emissions Trading System (EU ETS) established in 2005.
Types/Categories of Emissions Trading Schemes
- Cap-and-Trade Systems: Involves setting a maximum cap on emissions and allowing entities to trade permits to emit up to a certain level.
- Baseline-and-Credit Systems: Involves setting an emissions baseline, and entities receive credits for emissions reductions below this baseline which they can trade.
Key Events
- 1997 Kyoto Protocol: Introduced international carbon trading as a mechanism to achieve greenhouse gas reduction targets.
- 2005 EU Emissions Trading System (EU ETS): The largest multi-national emissions trading scheme, targeting CO₂ emissions from power plants, industrial plants, and airlines.
- 2015 Paris Agreement: Encouraged countries to engage in emissions trading as a method to meet their national targets (Nationally Determined Contributions).
Detailed Explanation
An Emissions Trading Scheme functions through the issuance and trading of emissions permits. The governing body sets a cap on the total amount of greenhouse gases that can be emitted by covered entities. These entities receive or purchase emission allowances, which they can trade among themselves.

Importance and Applicability
- Environmental Impact: Reduces greenhouse gas emissions, thereby mitigating climate change.
- Economic Efficiency: Encourages cost-effective emission reductions.
- Innovation: Incentivizes the development of new, cleaner technologies.
- Flexibility: Provides companies the flexibility to meet regulatory requirements in a cost-effective manner.
Examples
- EU ETS: Covering sectors such as power generation and aviation within the EU, this scheme aims to reduce greenhouse gas emissions by 43% by 2030, compared to 2005 levels.
- California Cap-and-Trade Program: Covers large GHG-emitting industries and aims to reduce emissions to 1990 levels by 2020 and 40% below 1990 levels by 2030.
Considerations
- Setting the Cap: The cap needs to be stringent enough to ensure significant reductions.
- Permit Allocation: Should be fair and transparent, balancing economic impacts with environmental goals.
- Market Volatility: Price volatility in the emissions market can impact economic stability.
Related Terms
- Carbon Tax: A direct tax imposed on carbon dioxide emissions.
- Renewable Energy Certificates (RECs): Tradable certificates representing the environmental benefits of 1 megawatt-hour of renewable energy.
- Clean Development Mechanism (CDM): A Kyoto Protocol mechanism that allows industrialized countries to invest in emission reduction projects in developing countries.
Comparisons
ETS vs Carbon Tax
- ETS: Cap sets a definite limit on emissions but can result in volatile prices.
- Carbon Tax: Provides price certainty but does not guarantee a specific level of emissions reduction.
Interesting Facts
- Innovative Financing: ETS has led to innovative financial instruments such as carbon credits and offsets.
- Global Reach: More than 40 national jurisdictions and over 20 cities, states, and regions are putting a price on carbon.
Inspirational Story
The EU ETS has led to significant reductions in CO₂ emissions in Europe. For instance, from 2005 to 2020, emissions from stationary installations covered by the EU ETS fell by around 35%, showcasing the potential of market-based mechanisms in addressing environmental challenges.
Famous Quotes
“The cap-and-trade approach is a smarter approach because it treats the environment as what it is: an asset that’s in limited supply.” — Fred Krupp
Proverbs and Clichés
- “You can’t manage what you can’t measure.”
- “Every ton of CO₂ matters.”
Expressions, Jargon, and Slang
- Cap: The maximum allowable emissions.
- Allowance: A permit to emit a specific amount of emissions.
- Offset: A credit for reducing emissions outside the cap-and-trade system.

Summary
The Emissions Trading Scheme is an innovative approach to managing and reducing greenhouse gas emissions. By creating a market for emission allowances, ETS incentivizes businesses to reduce emissions efficiently and encourages the development of cleaner technologies. With global implementation, ETS is proving to be an essential tool in the fight against climate change, balancing economic and environmental priorities.
