Carbon markets continue to grow as countries and companies work to reduce greenhouse gas emissions. Many firms now set net-zero targets. To reach those goals, they must cut emissions and offset the emissions they cannot eliminate. Carbon credit exchanges play an important role in this process by providing platforms where verified carbon credits are bought and sold.
Each carbon credit represents one metric ton of carbon dioxide removed or avoided through climate projects such as reforestation, renewable energy, or methane capture. Carbon exchanges help the credit markets work. These platforms support price discovery, market liquidity, and transparent trading.
This article explores the top carbon credit exchanges shaping the market in 2026: Intercontinental Exchange (ICE), Xpansiv, AirCarbon Exchange (ACX), and ESGCX. They span global compliance markets, voluntary carbon credit venues, and next-generation digital marketplaces.
Carbon Credits and Market Trends Shaping 2026
The carbon credit market has expanded quickly in recent years. Governments have introduced carbon pricing programs, while many corporations now use carbon credits as part of their climate strategies.
The global carbon market hit around $783 billion in 2024 and exceeded $1 trillion in 2025. This growth shows strong demand from corporate climate programs and government policies.
Voluntary carbon markets (VCMs) also continue to grow. The sector reached over $2 billion in traded value in 2024. Forecasts suggest strong growth ahead. The VCM could exceed $10 billion by 2030.
Several trends are shaping this market:
- Corporate climate commitments. More companies now include carbon credits in their climate strategies. Studies suggest that over 60% of sustainability-focused companies plan to increase their use of carbon offsets.
- Nature-based climate projects. Forestry and land-use projects remain major sources of credits. Forestry projects account for about 41% of the carbon credit supply, while renewable energy projects represent roughly 32%.
- Demand for high-quality credits. Many buyers now seek projects with strong verification and measurable impact. Around 44% of buyers prefer high-quality certified credits with stronger transparency standards.
- Digital technology in carbon markets. New platforms use digital tools and data systems to track carbon reductions. About 41% of market participants are adopting digital monitoring and verification systems.
As the market grows, trading infrastructure also becomes more important. Carbon exchanges provide the platforms that allow buyers and sellers to transact efficiently.
How Carbon Exchanges Support Climate Markets
Carbon exchanges create structured marketplaces for environmental assets. They connect buyers and sellers and provide transparent trading systems. These exchanges typically support two main types of markets.
- Compliance carbon markets: Governments create these markets through emissions trading systems. Companies must hold carbon allowances equal to their emissions. The European Union Emissions Trading System is the largest example.
- Voluntary carbon markets: Companies buy carbon credits voluntarily to offset emissions. These credits usually come from climate projects such as forest protection or renewable energy development.
Exchanges support both markets by providing tools for trading and price discovery. Some exchanges focus on derivatives and futures contracts. Others focus on spot trading of voluntary credits.
Reliable trading platforms also help reduce risk. They improve transparency by publishing prices and trading data. Several exchanges now play a major role in these global markets, and we’re breaking down each one of them so you’ll know your best pick.

Intercontinental Exchange (ICE): The Global Benchmark for Carbon Derivatives
The Intercontinental Exchange (ICE) operates one of the largest environmental derivatives markets in the world. It focuses mainly on compliance, carbon markets, and emissions allowance trading.
ICE hosts futures and options contracts tied to several carbon pricing systems. These include European Union Allowances (EUAs), which serve as a global benchmark for carbon pricing. The exchange has recorded strong trading activity in recent years.

North American environmental markets on ICE also reached record activity. In 2025, 6.2 million contracts were traded in these markets. This total included 4.2 million California Carbon Allowance contracts.
Because of its deep liquidity and strong participation, ICE remains a key platform for companies and financial institutions managing carbon price risk.
