Summary of Carbon Pricing for Climate Action

Core Content

Carbon pricing is a critical policy tool for addressing climate change by incorporating the cost of greenhouse gas (GHG) emissions into economic decision-making. It provides strong incentives for reducing emissions and can generate revenue more efficiently than alternative methods. However, it is not a standalone solution and must be complemented by other policies and investments.

Main Points

• Climate Change Context: To limit global temperature rise to 1.5°C above preindustrial levels, countries are submitting updated 2030 climate plans and pledging to reach net-zero emissions by 2050. Current national climate commitments are still insufficient to meet the Paris Agreement's goals.

• What is Carbon Pricing?
  Carbon pricing involves assigning a cost to GHG emissions, typically through:

  • Carbon Tax: A direct tax on emissions, set by the government.
  • Emissions Trading System (ETS): A cap-and-trade system where entities must surrender allowances for their emissions.
  • Crediting Mechanisms: Issue emissions reduction credits for projects that reduce emissions below a baseline.

  Carbon pricing can also be implicit, such as through removing fossil fuel subsidies or differential energy pricing.

• Role of Carbon Pricing
  Carbon pricing is a cost-effective tool for GHG mitigation and should be part of a broader policy package. It should be combined with:

  • Public investment in infrastructure and technology.
  • Regulatory changes (e.g., building norms, urban planning).
  • Complementary policies that address market failures and support the transition to low-carbon alternatives.

  The benefits of carbon pricing extend beyond climate goals, including cleaner air, improved public health, and enhanced macroeconomic stability.

• Key Challenges and Opportunities

  • Current carbon prices are generally too low to meet climate targets.
  • Political resistance and poor communication often hinder the implementation of ambitious carbon pricing policies.
  • Carbon pricing can be more effective in jurisdictions with strong institutions and transparent tax systems.
  • A global minimum carbon price is being advocated to align national and international climate ambitions, promote equity, and reduce competitive pressures between countries.

• State of Play

  • As of 2021, 64 carbon pricing instruments are in operation globally, covering over 20% of GHG emissions.
  • These instruments generate approximately $53 billion in annual revenue.
  • The majority of carbon prices remain below the recommended range of $40–$80 per tonne of CO₂e to meet the 2°C goal.
  • Many countries, especially in Asia, Africa, and Latin America, are exploring or implementing carbon pricing mechanisms, including carbon taxes, ETSs, and crediting schemes.

• Carbon Price Levels

  • Only a small portion of global emissions (less than 4%) are covered by carbon prices in the $40–$80 range.
  • Several jurisdictions, including the EU, Canada, and South Korea, have ambitious carbon pricing systems.
  • Some countries, like Canada, are planning to increase their carbon tax to $170 per tonne of CO₂e by 2030.

• Carbon Pricing Instruments and Conditions

  • Carbon Tax: Preferred for smaller economies and those with strong tax frameworks.
  • ETS: More suitable for larger, market-linked economies with political barriers to tax reform.
  • Crediting Mechanisms: Useful for sectors where other instruments face challenges, and to build capacity for carbon pricing.

• World Bank Group's Role
  The World Bank Group supports countries in designing and implementing carbon pricing policies through:

  • Convening power.
  • Research and knowledge sharing.
  • Country program support.
  • Environmental tax reforms that align with carbon pricing goals.

Key Takeaways

• Carbon pricing is essential for climate action but must be part of a broader policy mix.
• It can be implemented in various forms, each with its own strengths and limitations.
• Current carbon prices are insufficient to meet global climate goals.
• A global minimum carbon price could help increase ambition and ensure consistency.
• Public support and stakeholder engagement are vital for the success of carbon pricing reforms.
• Revenue from carbon pricing can be used for decarbonization, poverty alleviation, and economic development.

Conclusion

Carbon pricing is a powerful and flexible tool for driving climate action and economic transformation. However, its success depends on political will, institutional capacity, and effective communication. Countries must also address market failures and invest in complementary policies to ensure a fair and sustainable transition. The World Bank Group plays a crucial role in supporting these efforts through knowledge, research, and policy assistance.
