Carbon Pricing

Pricing Carbon: A $100 Billion Engine for Climate Action

In a world facing the dual pressures of slowing economic growth and escalating climate risks, a powerful tool is gaining traction: carbon pricing. According to the World Bank Group’s State and Trends of Carbon Pricing 2025 report, this mechanism is no longer a niche policy but a significant driver of climate action and a new source of revenue for governments.

The Global Shift in Carbon Pricing

The adoption of carbon pricing is accelerating globally. In 2024, direct carbon pricing covered 28% of global greenhouse gas (GHG) emissions, a substantial increase from just 5% in 2005. This expansion generated over $100 billion in revenue, a milestone reached for the second consecutive year. A significant portion of this money more than 50% is being reinvested into environmental, infrastructure, and development projects, creating a virtuous cycle of funding for a sustainable future.

Key drivers of this shift include:

• Expansion of major markets: China’s Emissions Trading System (ETS) alone expanded to cover 3 billion more tons of CO2 equivalent (tCO2e), bringing its total to 8 billion tCO2e.
• New entrants: Countries like India, Brazil, and Türkiye are implementing their own ETS frameworks, tailoring them to balance economic growth with climate goals.
• Diverse instruments: There are now 80 carbon pricing instruments in force globally, including 43 carbon taxes and 37 ETSs, showing a growing variety of approaches.

Challenges and Innovations

Despite this progress, significant challenges remain. The global average carbon price is only $5 per tCO2e, far below the $50–100 range needed to align with a 2°C climate scenario. Additionally, over a billion unretired carbon credits are “clogging” markets, and high-emitting sectors like agriculture remain largely unpriced.

However, innovation is addressing these gaps:

• New financial products: Carbon markets now feature insurance products and political risk guarantees to build confidence among investors.
• Corporate adoption: Internal carbon pricing tools are being used by 1,753 companies, marking an 89% increase since 2021 and signaling a growing corporate commitment to decarbonization.
• Demand for quality: Voluntary buyers are increasingly paying premiums for high-integrity credits, such as those from nature-based removal projects.

Why Carbon Pricing is a Development Tool

As global public debt approaches 100% of GDP and climate action requires trillions in annual investment, carbon pricing is emerging as a critical tool for development. It provides a stable and substantial revenue stream for governments, mobilizes private capital, and encourages innovation. By putting a price on pollution, it not only drives down emissions but also empowers nations to fund their own sustainable transitions, proving that climate policy and economic development can go hand-in-hand.
