Voluntary Carbon Credit Market Size, Share & Industry Analysis, By Project Type (Avoidance or Reduction Projects, Nature-Based Solutions, and Carbon Removal), By Buyer Type (Corporate, SME, Government, and Others), By End User (Aviation, Oil & Gas, Technology & Data Centers, Industrial, and Others), and Regional Forecast, 2026-2034

The global voluntary carbon credit market size was valued at USD 2.77 billion in 2025. The market is projected to grow from USD 3.75 billion in 2026 to USD 45.18 billion by 2034, exhibiting a CAGR of 36.48% during the forecast period.

Companies are increasingly using voluntary carbon credits to address offset emissions that cannot yet be eliminated through operational decarbonization. The growing adoption of corporate climate targets and expansion of voluntary carbon offset projects are key drivers of the market growth. According to the Science Based Targets initiative (SBTi), as of 2024, more than 4,200 companies globally have validated or committed to science-based climate targets, reflecting strong corporate alignment with the Paris Agreement. Many of these organizations incorporate carbon credits within broader climate strategies to compensate for residual emissions reductions while transitioning to low-carbon operations. Cap and trade indirectly influences the market by setting carbon price benchmarks and encouraging companies to offset the emissions beyond regulatory requirements.

At the same time, the supply of voluntary carbon credits has grown through large-scale offset projects, including forest conservation, afforestation and reforestation, renewable energy development, and methane capture initiatives. Data from Verra indicates that by 2023, the Verified Carbon Standard (VCS) program had issued over 1 billion carbon credits globally, demonstrating the expanding scale of voluntary carbon mitigation projects. In addition, governments and international organizations are increasingly encouraging private-sector participation in climate finance and nature-based solutions, particularly in emerging economies.

• For instance, in April 2023, Microsoft expanded its voluntary carbon credit procurement as part of its commitment to become carbon negative by 2030. The company signed agreements to purchase carbon removal credits from several projects, including reforestation, Bioenergy With Carbon Capture And Storage (BECCS), and direct air capture initiatives.

Some of the leading companies operating in the industry include Ecosecurities and Puro.earth, Biofílica Ambipar, BioCarbon Partners, and others. EcoSecurities is a global environmental company specializing in the development, sourcing, and commercialization of carbon credits and climate mitigation projects. The company supports governments, corporations, and financial institutions in implementing nature-based and technology-based carbon offset projects across sectors such as forestry, renewable energy, and land-use management. Carbon prices in the market are determined by project type, credit quality, certification standard, and buyer demand, typically varying widely based on environmental integrity and co-benefits.

VOLUNTARY CARBON CREDIT MARKET TRENDS

Growing Digital Infrastructure and Transparency Mechanisms is the Prominent Market Trend

A major trend shaping the market is the rapid development of digital infrastructure and transparency mechanisms to improve credit traceability and market integrity. Carbon registries and exchanges are increasingly adopting digital Monitoring, Reporting, And Verification (MRV) systems, blockchain-enabled registries, and satellite-based monitoring to ensure accurate measurement of emission reductions and prevent double counting of carbon credits. Clean energy projects such as wind, solar, hydro, and biomass generate carbon credits by reducing or avoiding greenhouse gas emissions compared to fossil fuel-based energy sources.

For instance, in June 2023, the Integrity Council for the Voluntary Carbon Market (ICVCM) released its Core Carbon Principles (CCPs) framework to establish global quality benchmarks for carbon credits and improve transparency in the market (Source: ICVCM). Similarly, in September 2023, Verra introduced updates to its Verified Carbon Standard (VCS) program, strengthening rules for project monitoring, credit issuance, and risk management to enhance market credibility (Source: Verra Registry Updates).

MARKET DYNAMICS

Expansion of Nature-Based Carbon Offset Projects to Drive the Market Growth

A key driver of the market is the rapid expansion of nature-based carbon offset projects, particularly those focused on forest conservation, reforestation, and land-use management. These projects generate verified emission reductions while also supporting biodiversity protection and community livelihoods. According to Verra, as of December 2023, more than 2,000 projects were registered under the Verified Carbon Standard (VCS) globally, with forestry and land-use projects representing a significant share of issued voluntary carbon credits (Source: Verra Registry Database).

In addition, in October 2023, the World Bank highlighted that nature-based solutions could deliver up to 30% of the global mitigation needed by 2030 to meet climate goals (Source: World Bank Climate and Nature Report). These projects are attracting increasing participation from corporations seeking high-quality carbon offsets while contributing to sustainable development objectives. These factors are anticipated to drive the CAGR during the forecast period.

MARKET RESTRAINTS

Concerns Over Credit Quality and Market Integrity to Hamper the Market Demand

A significant restraint in the market is the growing scrutiny over the environmental integrity and quality of certain carbon offset projects, particularly those linked to avoid deforestation and land-use activities. Questions regarding additionality, permanence, and accurate emissions measurement have led to increased market caution among buyers.

For instance, in January 2023, according to Verra forest projects, an investigation highlighted concerns about the credibility of some rainforest carbon credits issued under voluntary programs, prompting calls for stronger verification frameworks and transparency standards. In response to such concerns, registries and governance bodies have begun tightening methodologies and monitoring procedures to strengthen credit credibility.

MARKET OPPORTUNITIES

Integration of Carbon Credits with Global Carbon Removal Technologies to Propel Market Growth Opportunities

A major opportunity in the market is the growing integration of carbon removal technologies such as direct air capture (DAC), bioenergy with carbon capture and storage (BECCS), and enhanced mineralization, which can generate high-quality carbon removal credits. These technologies are attracting increasing investment as corporations seek durable carbon removal solutions to meet long-term climate commitments.

For instance, in September 2023, Climeworks announced the expansion of its Mammoth direct air capture plant in Iceland, which is expected to capture up to 36,000 tons of CO₂ annually once fully operational. Projects like these create verified carbon removal credits that can be sold in voluntary carbon markets. Additionally, governments and international climate initiatives are supporting carbon removal technologies as part of broader decarbonization strategies.

MARKET CHALLENGES

Uncertainty In Regulatory Frameworks And Carbon Market Alignment To Hinder Market Growth

A major challenge in the voluntary carbon credit market growth is the uncertainty surrounding regulatory frameworks and the alignment between voluntary and compliance carbon markets. Governments and international climate bodies are still developing policies that define how voluntary carbon credits can be used alongside global emissions reduction commitments under the Paris Agreement.

For instance, in November 2022, discussions during COP27 highlighted the ongoing need to clarify the implementation of Article 6 of the Paris Agreement, which governs international carbon trading mechanisms and corresponding adjustments between countries. These evolving rules create uncertainty for project developers and corporate buyers regarding how  these credits may be recognized within future compliance systems.
