Carbon Credit Market Size, Growth Rate and Regional Forecast to 2034: Drivers, Restraints and Segment Shares

The carbon credit market stood at USD 900 billion in 2025 and is forecast to reach USD 2870 billion in 2034. This analysis sets out the size, the growth rate, what supports the forecast, what could pull it down, and where the revenue sits. Every figure comes from CDI's carbon credit market report, which covers 2020-2024 as the historical period and 2026-2034 as the forecast period, with 2025 as the base year.

The market was worth USD 400 billion in 2020 and USD 820 billion in 2024. The base year, 2025, comes in at USD 900 billion. From that base the forecast carries a CAGR of 13.4% through to USD 2870 billion in 2034.

The historical period compounded at 17.6%. The forecast rate is lower, but it is applied to a much larger base. Anyone planning around this market should hold both numbers in view: the pace has already been demonstrated, and the open question is the mix of segments and regions that delivers the next stretch.

The report covers five regions: North America, Europe, Asia Pacific, Latin America, and the Middle East and Africa. It segments the market by market type, project type, credit approach, registry standard, vintage status, trading channel, instrument, buyer type, end-use industry and service layer.

Three points in the data explain the forecast.

First, growth is concentrated in one small line. Article 6 and Mechanism-Based Credits grows at 42.2% against the market's 13.4%. Its revenue moves from USD 1.5 billion to USD 50 billion, and its share of revenue from 0.2% to 1.7%. The market's overall 13.4% depends on that rate holding. Exposure to this line, and not to the market as a whole, determines a supplier's own rate.

Second, the regional base is large and still expanding. Europe is the largest region at USD 342 billion in 2025, 38% of the global total. It reaches USD 889.7 billion by 2034, at which point its share is 31%. Asia Pacific holds 30% of revenue, at USD 270 billion in 2025 and USD 1061.9 billion in 2034. Because both the existing revenue and the added revenue concentrate in these two regions, regional weighting matters more to a forecast than the number of regions covered.

Third, the trend is already in the record. The 17.6% historical rate, running from USD 400 billion in 2020 to USD 820 billion in 2024, shows the direction. The segment and regional sections of the report carry the detail on mix.

The forecast misses if policy and confidence move more slowly than assumed. The report names four conditions: cap tightening is delayed in key systems, new national systems launch late, mechanism authorisations stall, and integrity concerns keep voluntary buyers away. Together these hold prices and volumes below the base path.

The report sizes that outcome. The restraint case reaches USD 2330 billion by 2034, against USD 2870 billion in the base case, off an unchanged USD 900 billion in 2025.

There is also a structural drag. Compliance Market accounts for 96.9% of 2025 revenue, USD 872 billion, and grows at 12.6% against the market's 13.4%. Its revenue still reaches USD 2625 billion by 2034 and its share falls to 91.5%. That is a drag on the average, and the line is still growing.

The same concentration creates a dependency. One line dominates the market type axis, so anything that changes demand for Compliance Market changes the headline number. Nothing else on the axis carries that weight. At the regional level, Germany generates USD 78 billion of Europe's USD 342 billion in 2025, 22.8% of the region, and reaches USD 190 billion by 2034. Europe looks diversified when read as a region. Read by weight it is not, and the regional forecast inherits whatever happens in that one country.

By market type, the 2025 split is Compliance Market at 96.9%, Voluntary Market at 2.9%, and Article 6 and Mechanism-Based Credits at 0.2%. Share moves toward Article 6 and Mechanism-Based Credits, which reaches 1.7% in 2034. Taking a position there does not require displacing whoever holds Compliance Market, the harder and more expensive contest.

By region, the 2025 shares are:

• Europe, 38%
• Asia Pacific, 30%
• North America, 24%
• Middle East and Africa, 4.5%
• Latin America, 3.5%

The report states that Europe leads with 38% of global revenue through 2034. Asia Pacific is the region gaining share: it moves from 30% of revenue in 2025 to 37% in 2034, with revenue rising from USD 270 billion to USD 1061.9 billion. It grows faster than the market as a whole. Capacity and channel investment placed there compounds against a rising regional base.

Carbon credit demand sits alongside the build-out of other decarbonisation routes, and several of these markets show a similar regional pattern. In the green hydrogen market, Asia Pacific leads with 38% of global revenue through 2034. The grid-scale energy storage market shows Asia Pacific at 38% of revenue as well. For a narrower regional view, the GCC renewable energy market covers six Gulf countries, with Saudi Arabia leading at 44.12%.

For a buyer or supplier, the practical reading is a short list. Watch the Article 6 rate, because it carries the forecast's upside. Watch Compliance Market policy, because it carries the forecast's weight. Weight regional plans toward Europe and Asia Pacific, where both the base and the added revenue concentrate.
