Carbon Market Network
Every year, thousands of companies announce net-zero targets. But reducing emissions takes time, technology, and capital. So what do businesses do about the emissions they cannot eliminate right now They turn to the voluntary carbon market.
The voluntary carbon market (VCM) is one of the most talked-about tools in the global fight against climate change.
It connects companies that want to offset their carbon footprint with projects that reduce or remove greenhouse gas emissions from the atmosphere.
This guide covers everything you need to know about the voluntary carbon market – from the basics of how it works, to the types of credits available, to the biggest challenges the market faces today, and what is changing in 2026.
Whether you are new to carbon markets or looking to deepen your understanding, this article has you covered.
What Is the Voluntary Carbon Market?
The voluntary carbon market is a decentralized marketplace where companies, organizations, governments, and individuals voluntarily buy and sell carbon credits to offset their greenhouse gas (GHG) emissions.
The word “voluntary” is key here.
No law forces buyers to participate. They do it because of climate commitments, ESG goals, investor pressure, brand reputation, or a genuine desire to contribute to climate action.
Each carbon credit in the voluntary carbon market represents one metric tonne of CO2 equivalent that has been reduced, avoided, or removed from the atmosphere.
When a company buys a carbon credit and retires it, they are essentially saying: “One tonne of CO2 that would have gone into the atmosphere did not – because of this project – and we are accounting for it.”

Voluntary Carbon Market vs. Compliance Carbon Market
To understand the VCM properly, you need to know how it differs from the compliance carbon market.
Compliance carbon markets (also called cap-and-trade systems) are mandatory.
Governments set a legal cap on how much CO2 industries can emit.
Companies that exceed that limit must buy allowances or credits.
The EU Emissions Trading System (EU ETS) is the most well-known example.
The voluntary carbon market operates outside government mandates. Nobody has to participate. Companies buy carbon credits because they choose to, not because a regulator forces them.
| Feature | Voluntary Carbon Market | Compliance Carbon Market |
|---|---|---|
| Participation | Optional | Mandatory for regulated entities |
| Oversight | Private standards bodies | Government regulators |
| Credit types | Heterogeneous (vary by project) | Fungible allowances |
| Price range | Under $1 to $500+ per tonne | €60–€100 per tonne (EU ETS) |
| Flexibility | High – many project types | Low – strictly regulated |
| Enforcement | Deregistration | Financial penalties and legal action |
Both markets play important roles in the transition to a low-carbon economy.
Compliance markets create the regulatory floor. The voluntary carbon market drives additional climate action beyond what regulations require.
Why Does the Voluntary Carbon Market Exist?
The voluntary carbon market exists because the world cannot reach net zero fast enough using only policy and regulation alone.
Many companies genuinely want to act on climate but face technical, financial, or time-based constraints on how quickly they can reduce their own emissions.
Buying high-quality carbon credits allows them to:
- Offset unavoidable emissions in the short to medium term while they decarbonize
- Finance climate projects that would not happen without this revenue, such as tropical reforestation or carbon removal technology
- Meet corporate net-zero commitments and ESG reporting requirements
- Support sustainable development in communities around the world through projects that deliver jobs, clean water, biodiversity protection, and more
- Direct capital to emerging economies where high-impact, low-cost emissions reduction opportunities exist but would otherwise go unfunded
How Does the Voluntary Carbon Market Work?
The voluntary carbon market involves several key players and a specific process for creating and trading carbon credits. Here is how it works from start to finish.
Step 1: A Project Developer Designs a Climate Project
A project developer – this could be a company, NGO, government, or community organization – designs a project that will reduce or remove greenhouse gas emissions.
Examples include:
- Planting trees or restoring forests
- Protecting forests that would otherwise be cut down (REDD+)
- Building clean cookstoves that replace firewood
- Capturing methane from landfills or livestock
- Deploying direct air capture (DAC) technology
- Building renewable energy in communities that would otherwise rely on fossil fuels
Step 2: The Project Gets Validated
The project developer submits a Project Design Document (PDD) to a carbon standard body such as Verra or Gold Standard.
An independent third-party auditor then validates the project. They check that the emission reductions are:
- Additional: The reductions would not have happened without the carbon finance
- Measurable: Emissions can be quantified with scientific rigor
- Permanent: The carbon stored or reduced will not be reversed
- Real: The reductions genuinely happen, with no double-counting or overestimation
Step 3: The Project Runs and Monitors Its Impact
Once approved and registered, the project begins operations. The team collects ongoing data to track actual emission reductions.
This process is called Monitoring, Reporting, and Verification (MRV).
Technology is increasingly playing a role here. Satellite imagery, AI, and IoT sensors now help verify forest projects, soil carbon, and more with much greater accuracy.
Step 4: Carbon Credits Are Issued
After independent verification confirms the measured reductions, the carbon standard issues carbon credits to the project developer.
Each credit equals one tonne of CO2 equivalent reduced or removed.
The standard records these credits in a public registry, which anyone can access to confirm that specific credits exist and have not been double-counted or fraudulently retired.
Step 5: Credits Are Sold in the Market
Project developers sell their carbon credits to buyers through:
- Bilateral deals negotiated directly between buyer and seller
- Carbon brokers who match buyers and sellers
- Carbon exchanges and trading platforms for spot or forward purchases
- Carbon funds that pool credits from multiple projects
Step 6: Credits Are Retired
When a company decides to use a credit to offset its emissions, the credit is retired in the registry. This permanently removes it from circulation. No one else can ever use that credit again.
Retirement is the moment a carbon credit fulfills its purpose.
Who Buys Carbon Credits in the Voluntary Carbon Market?
Buyers in the VCM are diverse and growing.
- Large corporations: the dominant buyers. Companies in aviation, oil and gas, technology, consumer goods, and finance purchase credits as part of net-zero commitments. Microsoft, Google, Delta Air Lines, and Swiss Re are prominent examples.
- Small and medium-sized enterprises (SMEs): an emerging buyer group as ESG reporting requirements expand and customers demand sustainability credentials.
- Governments: buy voluntary credits to meet climate pledges that go beyond mandatory targets.
- Individuals: can buy credits through retail platforms to offset personal activities like air travel or home energy use, though this is a small share of total volume.
Types of Carbon Credits in the Voluntary Carbon Market
Not all carbon credits are the same. Understanding the different types helps buyers make more informed decisions.
Carbon Avoidance vs. Carbon Removal
This is the most important distinction in the VCM today.
Carbon avoidance (or reduction) credits represent emissions that were prevented from entering the atmosphere. Examples:
- Protecting a forest that would have been deforested (REDD+)
- Replacing coal-fired energy with solar or wind
- Distributing clean cookstoves that reduce wood burning
Carbon removal credits represent CO2 that has been actively pulled out of the atmosphere and stored. Examples:
- Reforestation and afforestation
- Biochar soil application
- Direct air capture (DAC)
- Enhanced rock weathering (ERW)
- Bioenergy with carbon capture and storage (BECCS)
The market is shifting sharply toward carbon removal. High-quality, durable removals are increasingly preferred by buyers who want their climate claims to hold up under scrutiny.
Nature-Based Solutions (NbS)
Nature-based solutions use natural ecosystems to capture and store carbon.
| Project Type | How It Works | Key Risk |
|---|---|---|
| REDD+ | Protects existing forests at risk of deforestation | Impermanence, inflated baselines |
| Afforestation / Reforestation | Plants trees on previously unforested land | Fire, disease, land use change |
| Improved Forest Management | Changes forest management to increase carbon storage | Permanence |
| Blue Carbon | Restores mangroves, salt marshes, seagrass beds | Policy and land tenure risk |
| Soil Carbon | Agricultural practice changes that build organic matter | Measurement difficulty |
Nature-based solutions are popular because they deliver strong co-benefits like biodiversity, community livelihoods, and clean water.
However, they face permanence risks from fire, disease, and climate change itself.
Technology-Based Carbon Dioxide Removal (CDR)
Engineered CDR approaches are growing fast in the voluntary carbon market.
Biochar Biomass is converted into a stable carbon-rich material through a process called pyrolysis.
The biochar is applied to soil, where the carbon remains for centuries.
As of late 2025, over 86% of all durable CDR credits delivered to the market were biochar carbon removals. Prices range from $150 to $270 per tonne.
Direct Air Capture (DAC) Machines use chemical processes to pull CO2 directly from ambient air and store it underground.
DAC offers the highest permanence but currently costs over $500 per tonne.
Companies like Microsoft, Google, Stripe, and Shopify have made early DAC purchases to help scale the technology.
Bioenergy with Carbon Capture and Storage (BECCS) Biomass is burned to generate energy, and the resulting CO2 is captured and stored underground.
BECCS accounts for roughly 75% of total durable CDR contracted since 2022 by volume.
Enhanced Rock Weathering (ERW) Crushed silicate rocks are spread on agricultural land, where they react with CO2 in rainwater and lock it into stable minerals.
ERW credits currently average over $200 per tonne.
Key Carbon Standards and Certifying Bodies
Carbon standards define the rules, methodologies, and oversight processes for generating valid carbon credits.
They issue credits into registries that track every credit from creation to retirement.
| Standard | Operator | Scale | Specialty |
|---|---|---|---|
| Verified Carbon Standard (VCS) | Verra | 2,300+ projects, 1.2B+ tonnes | Broadest coverage, all project types |
| Gold Standard (GS) | WWF + NGOs | 3,500+ projects, 100+ countries | Strong co-benefits, community projects |
| American Carbon Registry (ACR) | Winrock International | 788 projects, 289M+ tonnes | Americas-focused, diverse types |
| Climate Action Reserve (CAR) | CAR | North America | Landfill gas, forest, livestock methane |
| Plan Vivo | Plan Vivo Foundation | Community-scale | Community-led land use, Global South |
| Puro.earth | Puro.earth | Europe + North America | Engineered CDR only (biochar, ERW) |
Verra – Verified Carbon Standard (VCS)
Verra’s VCS is the most widely used voluntary carbon standard in the world, with over 1.2 billion tonnes of GHG reduced or removed across its registered projects.
It covers nearly every project type and hosts a publicly accessible registry.
Verra also runs the Climate, Community & Biodiversity (CCB) Standards, which assess projects for social and environmental co-benefits, and the SD VISta framework focused on contributions to the UN SDGs.
Gold Standard
Launched in 2003 by WWF and other NGOs, Gold Standard focuses on projects with strong social and environmental co-benefits.
Credits are often priced higher than VCS credits because of their strict verification requirements.
The ICVCM and Core Carbon Principles (CCPs)
For years, the voluntary carbon market lacked a universal quality benchmark. Buyers could not easily tell which credits were genuinely high-quality and which were not.
This opened the door to greenwashing and eroded market trust.
The Integrity Council for the Voluntary Carbon Market (ICVCM) was established to solve this problem.
The ICVCM is an independent governance body that has developed ten Core Carbon Principles (CCPs) – a global quality benchmark for voluntary carbon credits.
Credits that meet these principles can carry a CCP label in registries like Verra and Gold Standard, signaling they have passed rigorous tests.
The 10 Core Carbon Principles
- Effective governance
- Tracking
- Transparency
- Robust independent third-party validation and verification
- Additionality
- Permanence
- Robust quantification of emission reductions and removals
- No double-counting
- Sustainable development benefits and safeguards
- Contribution to net zero transition
As of late 2025, programs covering roughly 98% of historical market volume by retirements are now CCP-Eligible.
Over 30 methodologies across nature-based, methane, and removal categories have been approved under the framework.
The CCP label is rapidly becoming the industry standard for what buyers, regulators, and policymakers treat as a credible credit.
The Voluntary Carbon Markets Integrity Initiative (VCMI)
The VCMI complements the ICVCM from the demand side.
- ICVCM sets standards for credit quality
- VCMI provides a framework for how companies should make credible claims about their use of carbon credits
The VCMI’s Claims Code of Practice helps companies communicate their carbon market activity in ways that are transparent, verifiable, and aligned with global net-zero goals.
Together, the ICVCM and VCMI form a paired integrity system: the ICVCM certifies that credits are real, and the VCMI ensures companies use them responsibly.
How Are Carbon Credits Priced?
Carbon credit prices in the voluntary carbon market vary enormously. Here are indicative price ranges as of early 2026.
| Credit Type | Project Category | Approximate Price (per tonne CO2e) |
|---|---|---|
| Nature-based avoidance (low quality, older) | REDD+, older renewables | Below $1 |
| Nature-based avoidance (CCP-labeled) | High-quality REDD+ | $5 – $15 |
| Nature-based removal | Reforestation / afforestation | $5 – $20 |
| Biochar | Engineered CDR | $150 – $270 |
| Enhanced Rock Weathering (ERW) | Engineered CDR | $200+ |
| BECCS | Engineered CDR | ~$389 |
| Direct Air Capture (DAC) | Engineered CDR | $500+ |
What Drives These Price Differences?
- Durability: Tech-based removals lock carbon away for centuries. Nature-based avoidance is reversible. More permanent = higher price.
- Certification quality: CCP-labeled credits trade at significant premiums over uncertified alternatives.
- Additionality: Projects that clearly needed carbon finance to proceed are more valuable.
- Co-benefits: Credits with verified social and environmental co-benefits command higher prices.
- Vintage: Newer, recent vintages are preferred over older credits.
- Project location: European biochar credits cost more than similar projects in lower-cost regions.
Size and Growth of the Voluntary Carbon Market
The VCM has gone through dramatic swings in recent years.
Where the Market Stands (2025–2026)
- Market value in 2025: approximately $1.6 – $2.5 billion depending on methodology
- Credit retirements in 2025: approximately 157 million metric tonnes (down ~7% from 2024)
- Corporate climate commitments surged 227% in 2025, even as retirements fell

Key Players in the Voluntary Carbon Market Ecosystem
| Player Type | Role | Examples |
|---|---|---|
| Project Developers | Create emission reduction projects on the ground | NGOs, private companies, governments, communities |
| Carbon Standards | Define rules, issue credits, maintain registries | Verra, Gold Standard, ACR, CAR, Puro.earth |
| Third-Party Verifiers (VVBs) | Independent auditors who verify projects | DNV, Bureau Veritas, SCS Global Services |
| Carbon Brokers | Match buyers and sellers | South Pole, EcoAct, First Climate |
| Carbon Exchanges | Platforms for trading credits | Xpansiv, CBL, Pachama, Climatetrade |
| Corporate Buyers | Purchase and retire credits | Microsoft, Google, Delta, Swiss Re |
| Rating Agencies | Rate credit quality independently | Sylvera, BeZero Carbon, CarbonPlan |
| Governance Bodies | Set market rules and frameworks | ICVCM, VCMI, SBTi, CORSIA |
What Is CORSIA and How Does It Connect to the VCM?
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a program developed by the International Civil Aviation Organization (ICAO) to address aviation emissions.
Under CORSIA, airlines operating international routes are required to offset emissions above a baseline threshold.
They do this by purchasing eligible carbon credits – including certain voluntary market credits that meet CORSIA’s eligibility criteria.
CORSIA is significant because it creates a regulated demand signal for voluntary carbon market credits, bridging the compliance and voluntary worlds.
Airlines have become among the largest buyers in the VCM as a result.
Article 6 of the Paris Agreement and the VCM
Article 6 of the Paris Agreement creates a framework for countries to trade emissions reductions across borders to help meet their Nationally Determined Contributions (NDCs).
After years of incomplete negotiations at COP26, COP27, and COP28, negotiators finally agreed on the full Article 6 rulebook at COP29 in Baku in November 2024.
Two Key Mechanisms
Article 6.2 Enables bilateral trading of carbon credits (called Internationally Transferred Mitigation Outcomes, or ITMOs) between countries. This can involve voluntary carbon market credits authorized by the host country.
Article 6.4 Establishes a UN-supervised carbon crediting mechanism open to both countries and corporations. Sometimes called the Paris Agreement Crediting Mechanism (PACM).
Why This Matters for the VCM
- Creates a new internationally recognized framework for carbon trading that intersects with the VCM
- Credits authorized under Article 6.2 can be used for both NDC compliance and voluntary offsetting
- Brings more transparency and accountability norms into the VCM
- Pushes the entire market toward higher quality standards
Challenges and Criticisms of the Voluntary Carbon Market
The voluntary carbon market has real potential, but it also faces serious challenges.
1. Additionality Questions
The core promise of a carbon credit is that the emission reduction would not have happened without carbon finance. But proving this is genuinely difficult.
If a renewable energy project would have been built anyway because solar is now cheap, the credit has no real climate value.
Critics argue that a significant share of credits issued historically – particularly older renewable energy and REDD+ credits – fail this test.
2. Impermanence Risk
Nature-based removal is reversible. A forest that absorbs carbon can burn down tomorrow.
Buffer pools (where extra credits are held in reserve) exist to manage this risk, but impermanence remains a fundamental concern.
3. Inflated Baselines in REDD+ Projects
Several investigations published in 2022–2023, including a major analysis in the journal Science, found that many REDD+ forest projects based their claimed reductions on highly inflated deforestation scenarios.
Verra and other standards responded by revising methodologies, but the scandal damaged market confidence significantly.
4. Greenwashing Risk
Some companies have used carbon offsets as a substitute for real emissions reduction rather than a complement to it.
The EU’s Empowering Consumers Directive bans generic “climate neutral” claims from September 2026 unless backed by rigorous proof.
5. Market Fragmentation
The VCM has no single regulator. Multiple competing standards, registries, and methodologies create confusion.
The ICVCM’s Core Carbon Principles exist specifically to address this by providing a common baseline across standards.
6. Human Rights and Community Concerns
Some carbon projects – particularly large-scale forestry projects – have faced criticism for displacing or harming indigenous communities.
Land rights violations, lack of free prior and informed consent, and inequitable benefit sharing have been documented in multiple cases.
The CCPs include specific safeguards, but implementation remains a work in progress.
7. The Gap Between Commitment and Action
Despite a 227% surge in corporate climate commitments in 2025, credit retirements actually fell 7% that same year.
Over 80% of high-durability carbon removal capacity is currently at risk of not being realized without additional offtake commitments.
How to Buy Carbon Credits: A Practical Step-by-Step Guide
Step 1: Measure Your Carbon Footprint
Before buying any carbon credits, measure your organization’s greenhouse gas emissions across:
- Scope 1 – direct emissions from owned or controlled sources
- Scope 2 – indirect emissions from purchased electricity and heat
- Scope 3 – all other indirect emissions across your value chain
Use the GHG Protocol Corporate Accounting Standard as your framework.
Step 2: Reduce First
Carbon credits should complement genuine emission reductions, not replace them. Set science-based targets to reduce your emissions in line with a 1.5°C pathway.
Use the Science Based Targets initiative (SBTi) framework for credible target-setting.
Step 3: Define What Type of Credits You Need
- Want to claim credible carbon neutrality? You need CCP-labeled credits with strong additionality.
- Want to contribute to cutting-edge climate solutions? Consider biochar or DAC removal credits.
- Have an SDG alignment goal? Look for Gold Standard or CCB-certified projects with verified co-benefits.
- Want to support biodiversity? Look for REDD+ projects with strong safeguards and recent methodology revisions.
Step 4: Evaluate Credit Quality
Do not just buy the cheapest credits. Ask these questions:
- Does the credit carry the CCP label or come from a CCP-Eligible methodology?
- Is the project registered with a reputable standard (Verra, Gold Standard, etc.)?
- Has it been recently verified by an accredited third-party auditor?
- Are the registry serial numbers publicly available?
- Has the credit been independently rated by Sylvera or BeZero Carbon?
Step 5: Choose How You Buy
- Spot market purchases on exchanges like Xpansiv for immediate access to existing credits
- Forward contracts (offtake agreements) to pre-purchase future credits from specific projects
- Portfolio approaches through carbon funds or asset managers
- Direct relationships with project developers for deeper project information and better pricing
Step 6: Retire and Report Transparently
Once purchased, retire credits in the registry and report their retirement in your sustainability disclosures.
Be specific: disclose the project name, standard, vintage year, and quantity retired.
Avoid vague claims like “we are carbon neutral.” Instead, be transparent about what you have reduced, what you have offset, and how.
What Makes a High-Quality Carbon Credit?
| Principle | What It Means |
|---|---|
| Additionality | The reduction would not have happened without carbon finance |
| Permanence | The carbon stored will not be reversed over time |
| No double-counting | The credit is recorded once, used once, retired once |
| Measurability | Reduction is quantified with a robust scientific methodology |
| Transparency | All project data, verification reports, and registry records are public |
| Co-benefits | Delivers additional value — jobs, biodiversity, clean water, community health |
| Third-party verification | Independently confirmed by an accredited auditor |
| Recent vintage | Credits from recent years, reflecting current conditions |
Emerging Trends in the Voluntary Carbon Market in 2026
1. The Quality Revolution
The era of cheap, questionable credits is ending. Buyers increasingly pay significantly more for CCP-labeled, high-integrity credits.
Generic, low-quality avoidance credits are losing market share rapidly.
2. The Rise of Carbon Removal
The market is shifting from avoidance to removal. Corporate net-zero frameworks increasingly require durable carbon removal and not just emission avoidance.
This is driving exponential growth in biochar, DAC, ERW, and BECCS projects.
3. Article 6 Implementation
With the COP29 Article 6 rulebook finalized, 2025 and 2026 mark the beginning of real-world implementation.
Countries are establishing authorization frameworks and beginning to issue ITMOs, creating new intersections between compliance and voluntary markets.
4. AI, Satellite, and Digital MRV
Technology is transforming how carbon projects are measured and verified. Companies like Pachama use satellite imagery and machine learning to monitor forest carbon remotely and continuously, making MRV cheaper, faster, and more accurate.
5. EU Carbon Removal and Carbon Farming (CRCF) Regulation
Adopted in late 2024 and now in implementation, the CRCF Regulation builds a regulatory framework for certifying carbon removals in Europe.
The EU is also establishing a Buyers’ Club to pool corporate voluntary demand for CRCF-certified credits.
6. Consolidation of Buyers
Market demand is increasingly concentrated among fewer, larger buyers.
The top corporate buyers are having outsized influence on which project types scale and which quality standards gain traction.
7. Forward Offtake Agreements
Buyers are moving away from spot purchases toward long-term forward contracts.
By pre-buying future credits, buyers help finance project development, secure future supply, and often gain better pricing.
8. Greenwashing Regulation Tightening
The EU’s Empowering Consumers Directive, banning generic “climate neutral” claims from September 2026, is the clearest sign that regulators are cracking down on greenwashing claims not backed by rigorous verification.
9. Asia-Pacific Growth
Asia-Pacific is poised to become the VCM’s center of gravity, forecast to grow at 36–58% CAGR – outpacing all other geographies. China leads through massive renewable deployment and methane initiatives.
10. Integration with Compliance Frameworks
More compliance regimes are incorporating voluntary market credits. CORSIA uses VCM credits.
California’s cap-and-trade program allows qualifying offsets. As Article 6 operationalizes, the boundary between voluntary and compliance markets will continue to blur.
Real-World Corporate Examples
| Company | VCM Activity |
|---|---|
| Microsoft | Large BECCS offtake agreements; major buyer of biochar and DAC credits; aims to be carbon negative by 2030 |
| Early agreements with DAC projects; committed to 24/7 carbon-free energy and net-zero across all operations by 2030 | |
| Stripe / Shopify / Frontier | Committed nearly $1 billion through the Frontier advance market commitment to purchase CDR credits by 2030 |
| Delta Air Lines | One of the largest aviation buyers of voluntary carbon credits, partly driven by CORSIA compliance |
| Swiss Re | Committed to purchasing carbon removal credits; invested in nature-based solutions as part of a broader sustainability strategy |
Frequently Asked Questions (FAQs)
Q1. What is a carbon credit?
A carbon credit is a tradeable certificate representing the reduction, avoidance, or removal of one metric tonne of CO2 or its equivalent in other greenhouse gases. When a company buys and retires a credit, it claims that tonne as an offset to its own emissions.
Q2. How is the voluntary carbon market different from a carbon tax?
A carbon tax is a government-imposed fee on greenhouse gas emissions – it is mandatory. The voluntary carbon market is optional. A carbon tax makes emitting more expensive. The VCM allows companies to finance climate projects elsewhere to offset their own emissions voluntarily.
Q3. Is buying carbon credits enough to be “carbon neutral”?
No. True carbon neutrality requires measuring your full emissions, reducing them as much as possible, and using high-quality credits only for truly unavoidable residual emissions. Using credits as a substitute for reducing emissions is widely regarded as greenwashing, and EU regulations from September 2026 specifically ban unsupported “climate neutral” claims.
Q4. How much do carbon credits cost?
Prices range from below $1 per tonne for old, low-quality avoidance credits to over $500 per tonne for premium direct air capture removal credits. High-quality, CCP-labeled credits cost far more than market averages suggest. Buyers should budget based on the type and quality of credits they actually need.
Q5. What is additionality in carbon markets?
Additionality means the emission reduction would not have happened without the carbon finance from the credit. If a project would have proceeded anyway – without carbon revenue – the credit has no real climate value because no “additional” reduction occurred.
Q6. What does it mean to “retire” a carbon credit?
Retiring a credit means permanently removing it from the market registry so it can never be used again. Retirement is the moment a credit is actually applied to offset emissions. It prevents double-counting and ensures one tonne of CO2 is only claimed once.
Q7. What is REDD+?
REDD+ stands for Reducing Emissions from Deforestation and Forest Degradation (the “+” represents activities like sustainable forest management). It pays project developers or tropical countries to protect forests that would otherwise be cut down. REDD+ credits have been heavily criticized for overstated baselines, prompting major methodology revisions across standards.
Q8. What is the ICVCM?
The Integrity Council for the Voluntary Carbon Market (ICVCM) is an independent governance body that established the Core Carbon Principles – a global quality benchmark for voluntary carbon credits. Credits from methodologies approved under the CCPs can carry the CCP label, signaling they meet rigorous international integrity standards.
Q9. Can individuals buy carbon credits?
Yes. Many platforms allow individuals to purchase carbon credits to offset personal activities like air travel or home energy use. However, individual retail purchases represent a very small share of total VCM volume compared to corporate buyers.
Q10. What is the future of the voluntary carbon market?
The VCM is expected to grow substantially through 2035, driven by corporate net-zero commitments, Article 6 implementation, tightening greenwashing regulations, and the shift toward high-quality durable carbon removal. The market is consolidating around quality – fewer, better credits replacing a high volume of questionable ones.
Conclusion
The voluntary carbon market is not perfect. It has faced scandals, quality problems, and legitimate criticism.
But it also represents something genuinely important – a mechanism for directing billions of dollars toward real climate action that would not otherwise happen.
As the market matures, the quality revolution is taking hold. The ICVCM’s Core Carbon Principles are reshaping what a credible carbon credit looks like. Article 6 is creating a stronger international foundation for carbon trading.
Biochar, DAC, and ERW are bringing more durable removals to market. Buyers, investors, and regulators are demanding more transparency and accountability than ever before.
The voluntary carbon market in 2026 is not the same market it was in 2021. It is more rigorous, more sophisticated, and more closely scrutinized. That is a good thing.
For companies serious about climate action, the message is clear: reduce first, offset the rest with integrity, and choose credits that deliver real, measurable, permanent climate impact.
The voluntary carbon market, done right, is not a workaround for climate action. It is one of the most powerful tools we have to accelerate it.
