What is Carbon Credit Pricing Scheme ?

By -

The Carbon Credit Pricing Scheme is a mechanism designed to encourage the reduction of greenhouse gas (GHG) emissions by placing a monetary value on carbon emissions. It incentivizes organizations and countries to adopt cleaner technologies and practices. Here’s a detailed overview of the scheme:

1. Understanding Carbon Credits

A carbon credit represents the right to emit one metric ton of carbon dioxide (CO₂) or its equivalent in other GHGs. These credits can be earned by reducing emissions below a baseline level or through activities like afforestation or renewable energy projects.

2. Key Components of Carbon Credit Pricing

a. Pricing Mechanisms

  1. Carbon Tax:

    • Directly sets a price on carbon emissions.
    • Emitters pay for each ton of CO₂ released into the atmosphere.
    • Example: Canada's carbon tax program.

  2. Emissions Trading System (ETS):

    • A cap-and-trade system where a limit (cap) is set on emissions.
    • Companies that emit less than their cap can sell surplus credits to others.
    • Example: European Union ETS.

b. Market-Driven Pricing

  • Carbon credit prices are determined by supply and demand in voluntary or compliance markets.
  • Prices fluctuate based on regulatory policies, technology advancements, and market confidence.

c. Subsidies and Incentives

  • Governments may offer financial incentives for projects generating carbon credits (e.g., renewable energy, methane capture).

3. Determining Carbon Credit Prices

Several factors influence the price of carbon credits:

  1. Market Type:

    • Compliance Markets: Driven by government regulations. Prices are generally higher due to strict standards.
    • Voluntary Markets: Driven by corporate and individual commitments. Prices may vary widely.

  2. Sector and Geography:

    • Renewable energy credits in developing countries may be priced lower than reforestation credits in developed nations.

  3. Project Type:

    • High-impact projects (e.g., reforestation, carbon capture) often command premium prices.

  4. Global Regulations:

    • International treaties like the Paris Agreement set ambitious goals for reducing emissions, impacting prices.

4. Current Trends in Carbon Credit Prices (2024)

  • Prices range widely:
    • Voluntary Market: $5 to $50 per ton of CO₂.
    • Compliance Market: $50 to $150 per ton of CO₂, particularly in the EU ETS.
  • Increasing demand from corporates aiming for net-zero targets has boosted voluntary market prices.

5. Benefits of the Carbon Credit Pricing Scheme

  • Promotes investments in low-carbon technologies.
  • Encourages sustainable practices.
  • Provides a revenue stream for climate-positive projects.
  • Supports global efforts to limit temperature rise to 1.5°C above pre-industrial levels.

6. Challenges and Criticisms

  • Price Volatility: Fluctuations can create uncertainty for investors.
  • Double Counting: Risk of the same credit being sold multiple times in voluntary markets.
  • Equity Concerns: Developing nations often face challenges in accessing carbon credit markets.

7. Future Outlook

  • With increasing global focus on decarbonization, carbon credit prices are expected to rise.
  • Innovations like blockchain are being explored for transparency in trading.
  • Carbon border adjustment mechanisms (CBAMs) may impose tariffs on imports based on embedded emissions, further influencing prices.

Carbon pricing instruments are tools designed to put a monetary value on greenhouse gas (GHG) emissions, incentivizing emitters to reduce their carbon footprint. The two primary categories of carbon pricing instruments are market-based mechanisms and direct pricing mechanisms. Here's a breakdown of the various instruments:

1. Market-Based Mechanisms

These rely on market forces to regulate and reduce emissions.

a. Emissions Trading System (ETS)

Also known as Cap-and-Trade.

  • How It Works: A cap is set on the total emissions allowed in a system. Emitters receive or buy allowances (carbon credits), each permitting the emission of one ton of CO₂.
  • Trading: Companies that emit less than their allowances can sell surplus credits to others.
  • Examples:
    • European Union ETS
    • California Cap-and-Trade Program

b. Baseline-and-Credit System

  • How It Works: Emitters are assigned a baseline level of emissions. Companies that reduce emissions below their baseline generate credits, which they can sell to others.
  • Examples:
    • New South Wales Greenhouse Gas Abatement Scheme (Australia)

c. Offset Mechanisms

  • Allow entities to invest in projects outside their operations (e.g., afforestation, renewable energy) to offset their emissions.
  • Often used in voluntary carbon markets.
  • Examples: Verified Carbon Standard (VCS), Gold Standard.

2. Direct Pricing Mechanisms

These impose a fixed price on carbon emissions or fuels based on their carbon content.

a. Carbon Tax

  • How It Works: Emitters pay a fixed fee for every ton of CO₂ emitted.
  • Advantages: Simple to implement, provides price certainty.
  • Examples:
    • Sweden’s Carbon Tax (one of the highest globally, ~$140 per ton of CO₂).
    • British Columbia Carbon Tax (Canada).

b. Fuel Taxes

  • Taxes on fossil fuels based on their carbon content (e.g., coal, oil, natural gas).
  • These are indirect forms of carbon pricing and are commonly implemented in many countries.

3. Hybrid Mechanisms

These combine features of both market-based and direct pricing instruments.

a. Price Floor and Ceiling in ETS

  • Sets minimum and maximum prices for carbon credits in trading systems to manage price volatility.
  • Example: California’s Cap-and-Trade system includes a price floor.

b. Carbon Fee and Dividend

  • How It Works: Emitters pay a carbon fee, and the revenue is redistributed to citizens as dividends.
  • Example: Proposed policies in the U.S., like the Climate Leadership Council’s plan.

c. Carbon Contracts for Difference (CCfD)

  • Governments agree to pay the difference between the market price of carbon and a higher fixed price, ensuring long-term price certainty for investors.
  • Example: Used to promote clean hydrogen and industrial decarbonization in Europe.

4. Other Innovative Instruments

a. Carbon Border Adjustment Mechanism (CBAM)

  • Tariffs on imported goods based on their embedded carbon emissions.
  • Ensures a level playing field for domestic industries subject to carbon pricing.
  • Example: European Union's CBAM (expected implementation: 2026).

b. Internal Carbon Pricing

  • Organizations set their own internal carbon price to guide decision-making and investment.
  • Types: Shadow pricing, implicit pricing, and explicit pricing.
  • Example: Microsoft, BP, and Shell use internal carbon pricing.

c. Sector-Specific Carbon Pricing

  • Pricing targeted at specific industries, such as aviation or shipping.
  • Example: International Civil Aviation Organization's (ICAO) CORSIA program.

5. Voluntary Carbon Markets

  • Individuals or companies voluntarily purchase carbon offsets to neutralize their emissions.
  • These markets operate outside regulatory frameworks and cater to entities aiming for net-zero goals.

Conclusion

Carbon pricing instruments vary in approach, scope, and complexity, but they all aim to achieve the same goal: reducing emissions cost-effectively while promoting sustainable practices. The choice of instrument depends on national priorities, economic considerations, and sector-specific challenges.

In most of the western countries and developing countries are launching the new concept called the “ Recycling Malls ” in major cities and towns across their countries. The main objective of the recycle mart is to sell the used products (ex: used plastic, glass, paper, etc.). This is an innovative way of making things and helping in reducing environmental pollution in the surroundings across the globe.   There are different kinds of pollutions that are generated effecting Air, Water, Land, Food, Sea, Ocean pollutions. It is damaging the EARTH gradually and impacting directly and indirectly that are highly toxic and increase the scope of new harmful viruses etc.   Issue: Wastes are different types that are generated in the world which is mostly produced by man. Anything that is produced excess and unable to control is added into pollutant list. The recycling plants are getting adopted across the globe with different techniques, methodologies and Strategic ways in c...
