With global temperatures continuing to rise, governments and corporations are looking for ways to reduce greenhouse gas emissions. One method that’s gaining popularity is the use of Carbon Credits to incentivize emissions reductions and support renewable energy development. This article is the 3rd in a series we’re doing based on our widely respected Climate Change and Carbon Markets 2023 Report.  Previous posts in the series are: 

In this article we examine what carbon credits are, and how they work as part of a broader emissions reduction strategy.

 

What Are Carbon Credits?

A carbon credit represents one ton of carbon dioxide or other greenhouse gas that is prevented from entering the atmosphere. Each credit is assigned a unique identification number that allows it to be tracked and traded.

 

How Are Carbon Credits Created? 

Carbon credits are generated through activities like renewable energy generation, reforestation projects, or installing technology to reduce industrial emissions. Organizations can then purchase these credits to offset their own emissions and essentially pay someone else to reduce greenhouse gases on their behalf. This gives companies an economic incentive to finance projects that take carbon out of the atmosphere.

 

How big is the Carbon Credit market? 

Globally, the voluntary carbon credit market was estimated at $1 billion in 2021. Meanwhile the compliance carbon credit market, which consists of credits generated under cap-and-trade systems and carbon taxes, was valued around $272 billion. As more jurisdictions enact climate policies, demand for carbon credits is expected to grow.

 

Cap-and-Trade Systems

One of the most common uses of carbon credits is in emissions trading systems, also known as cap-and-trade. This revolutionary approach to controlling carbon emissions sets caps on the amount of carbon that can be released into the atmosphere, and creates a market where companies can trade carbon allowances. Those who wish to emit more can purchase additional allowances, while others might sell their unused ones.

 

How Does Cap-and-Trade work?

Under a cap-and-trade system, the government sets an overall legal limit on greenhouse gas emissions from major sources like power plants and heavy industry. Companies receive or buy emission allowances up to their allotted share of the cap. If they reduce emissions below their cap, they can sell spare allowances to other companies as carbon credits.

 

Using Carbon Credits in Cap-and-Trade Systems

This creates a financial incentive for organizations to cut their carbon footprints, as they can profit from selling excess carbon credit allowances while still meeting their own targets. Meanwhile companies that would struggle to reduce emissions can purchase carbon credits as a flexible, cost-effective way to comply with regulations. The overall emissions cap guarantees the desired environmental outcome is still achieved.

 

Using Carbon Credits in Carbon Tax Systems

In a carbon tax system, governments directly tax emissions from sources like electricity generation and transportation fuels. This gives companies a standing financial reason to look for ways of reducing their tax burden by cutting carbon output.

Carbon credits can provide tax relief in two main ways:

  • Credits can be surrendered to offset tax obligations directly. Each credit represents one tonne of emissions that a company doesn’t have to pay tax on.
  • Revenue from credit sales can help finance emission reduction projects, lowering a company’s overall taxable emissions.
 

Voluntary Carbon Credit Purchases

Beyond regulatory requirements, some organizations and individuals buy carbon credits on a voluntary basis. Reasons for voluntary credit purchases include:

  • Corporate social responsibility – Companies offset their emissions to demonstrate a commitment to sustainability to customers and shareholders.
  • Carbon neutral products – Retailers and manufacturers invest in credits to compensate for emissions associated with making and transporting products, allowing them to sell carbon neutral or “net zero” goods.
  • Voluntary reductions – People offset things like air travel through credits to reduce their personal carbon footprint.
  • Pre-compliance buying – Companies purchase credits speculatively in anticipation of future climate regulations.
 

Carbon Credit Project Categories

There are many types of activities that can generate saleable carbon credits, provided they satisfy the key requirement of demonstrably reducing or removing emissions. Some major project categories include:

  • Renewable energy – Building wind, solar or hydropower instead of fossil fuel generation.
  • Energy efficiency – Upgrading equipment, appliances and processes to reduce energy usage and associated emissions.
  • Fuel switching – Transitioning from higher emission fuels like coal to lower carbon alternatives like natural gas or bioenergy.
  • Industrial gas destruction – Destroying potent greenhouse gases like nitrous oxide or hydrofluorocarbons.
  • Waste management – Installing gas capture systems at landfills and livestock operations to prevent methane release.
  • Forestry – Planting trees or avoiding deforestation through forest conservation programs. Trees naturally absorb CO2 as they grow.
  • Carbon capture and storage – Technologically capturing emissions at source and permanently sequestering them underground.
  • Agricultural practices – Adopting techniques like low/no-till cultivation, crop rotation and organic soil management to boost carbon storage in farmland.

Voluntary demand makes up a relatively small segment of the global carbon credit market, but this segment has seen significant growth over the past decade – According to data from Forest Trends’ Ecosystem Marketplace, voluntary carbon credit retirements have increased over 20-fold from 10 million tons CO2e in 2010 to 220 million tons CO2e in 2020. The value of the voluntary carbon market more than tripled between 2017 and 2021, reaching an estimated $1 billion in transactions last year, and this segment  is expected to play an increasing role as sustainability awareness grows among businesses and consumers.

 

Are Carbon Credits Effective?

Carbon credits are sometimes criticized as an excuse for companies to keep polluting while paying others to enact change. However, when paired with sound climate policies, credits can provide an efficient market mechanism to drive meaningful emissions reductions.

 

Conclusion – Carbon Credits for a Net-Zero Future

With rising worldwide emissions, new strategies are essential for achieving global climate targets. Carbon pricing policies like emissions trading and carbon taxes create regulatory and economic incentives to tackle greenhouse gas output. Within this context, carbon credits offer a market mechanism for driving cost-effective emissions reductions while supporting renewable energy and climate-smart development.

COP30 Moves Into a More Ambitious Phase: Key Updates to Know

COP30 Moves Into a More Ambitious Phase: Key Updates to Know

COP30, held in Belém, Brazil, has shifted into higher gear. Ministers are now at the negotiation table. The talks are shifting from technical discussions to tough political bargaining.

The COP30 presidency has released a new summary document outlining 21 different options for resolving some of the most contentious issues. This is signaling a push for real progress.

A Menu of Options from the Presidency

At the heart of the summit is a 5-page note from COP30 President André Corrêa do Lago. This document does more than guide discussions: it frames possible outcomes by laying out 21 options across four major areas.

These major issue-areas include:

  • Strengthening national climate plans: whether countries should be urged to do more on their new emissions-reduction pledges.
  • Climate finance: especially the allocation of a $300 billion aid target from richer to poorer countries. Current climate finance flows are far too low. About $500 billion is available each year, but the world needs $1.3 trillion by 2030–2035. Rich countries made a promise: to give $100 billion a year by 2020. But they didn’t meet this goal.
  • Trade and climate: how to deal with trade barriers and climate-related trade disputes. Climate-related tariffs and disputes are rising. This shows that COP30 needs to tackle trade measures in a more organized way.
  • Transparency and reporting: improving how countries report their emissions and climate progress.

global climate finance vs COP30 target

The presidency says these options are not fixed decisions. Instead, they reflect different pathways that countries can endorse or reject. This structure is meant to give negotiators flexibility while still working toward a coherent package.

Some options call for a new three-year climate finance program. Others suggest simpler steps, like reaffirming current commitments.

One idea for trade is to host roundtables about how climate policies impact cross-border trade. Another is to create a formal platform to discuss climate-related trade measures under the UNFCCC.

  • The presidency also emphasizes core themes: multilateralism, putting people at the center, and moving from negotiation to implementation.

COP30 metrics show the size of these talks. Nearly 200 countries and many observer groups are represented.

Analysts say the document suggests a bolder COP30 outcome that could lead to roadmaps for phasing out fossil fuels. Also, it may establish a clearer link between climate finance and accountability.

Summary Note on COP30 Presidency consultations

Host Brazil Urges Action, Not Just Words

Brazil, as host, is pressing hard for concrete results. It has sent a strong message through a letter and its draft text, urging parties to negotiate in good faith and aim for real deliverables. And so negotiations extended into the nights to finalize the talks. 

President Lula da Silva and COP President do Lago both emphasize that talks must lead to a practical roadmap, not vague promises. They argue that to meet the challenges ahead, especially on fossil fuels and finance, countries must chart out “who does what, when, and how.”

In particular, Brazil is pushing for a roadmap to phase out fossil fuels. It sees this as both an ethical and strategic move: phasing out fossil fuels in a just way, while respecting development needs.

  • Global fossil fuel subsidies are about $500 billion each year.

Reform efforts are now closely tied to COP talks. This adds urgency to Brazil’s proposals.

Money Talks: Climate Finance Stalls Negotiations

Even though the presidency’s proposal is broad, finance continues to act as a major roadblock. Developing countries say rich nations still haven’t met their climate aid promises. This includes a goal of $300 billion each year by 2035. The shortfall compared to the estimated needs of $1.3 trillion annually illustrates the scale of the finance gap.

300 billion climate finance goal

These financial disputes have even prompted critics to warn that the absence of real funding could undermine the entire summit. Some say that until money flows, other issues — like emissions or transparency — may remain stalled.

South Korea’s Big Coal Shift

Meanwhile, a significant moment came when South Korea announced it would phase out many of its coal-fired power plants by 2040. The country joined the Powering Past Coal Alliance.

Under the plan, 40 out of its 61 coal plants are set to retire by 2040. The remaining 21 will be evaluated for closure later, based on economic and environmental factors.

South Korea aims to have 45% of its electricity supplied by renewables by 2040, supplemented by nuclear and gas. This commitment signals a major step toward a cleaner energy mix and the creation of green jobs.

south korea energy mix

But the pledge also raises geopolitical stakes. South Korea has long been a major coal importer. Its decision could ripple through global coal markets, especially affecting exporting countries.

The country accounts for about 1.5% of global emissions. This shows that its policies, though smaller than those of China or the U.S., still hold significant regional influence.

China Steps Up as the United States Steps Back

Complicating dynamics at COP30 is the notable absence of the United States. As such, China has stepped up its diplomatic efforts. With no top U.S. officials around, it is pushing for stronger cooperation among many countries.

Beijing’s delegation sees itself as a stabilizing force. They push for climate finance, technology cooperation, and working together on the Paris Agreement. China accounts for around 31% of global emissions, making its position critical for the overall climate outcome.

Before the summit, China updated its climate goals. It plans to cut emissions by 7–10% from peak levels and increase non-fossil energy use to 30% of total energy consumption by 2035.

Analysts note that, even with these plans, long-term goals and accountability are still necessary to keep warming within 1.5°C.

What’s at Stake: A Turning Point for COP30

As COP30 presses on, what happens in the next few days could define its legacy. Here are the key things to watch out for as the summit takes its second week run:

  • The presidency’s “menu” of options gives countries flexibility, but risks producing watered-down outcomes.
  • Finance remains the most difficult divide. Without real funding, many fear COP30 could fall short.
  • Brazil is pushing for a fossil-fuel roadmap anchored in fairness — but that depends on buy-in from major emitters.
  • South Korea’s coal commitment could reshape export markets and send a signal to other coal-dependent nations.
  • China’s rising role highlights how power dynamics are shifting, especially in the U.S.’s absence.
  • Trade and climate measures, including tariffs and disputes, remain an area where COP30 could produce tangible frameworks to avoid future conflicts.

In short, COP30 may not just be another negotiation; it could be a turning point. Whether countries seize the moment to deliver real change will determine if this climate conference becomes a source of momentum or just another talking summit.

Carbon Credit Prices Hit New 2025 Highs: 7 Safe Platforms Every Buyer Should Know

Published

on

Carbon credit prices jumped to new 2025 highs this week, sparking intense market activity and a wave of interest from companies and investors racing toward net-zero goals. Fresh data from MSCI showed that high-rated credits traded at more than 300% above lower-rated ones in May.

Meanwhile, the MSCI Global ARR Index—which tracks afforestation, reforestation, and revegetation projects—climbed to a record $21.3 per ton in June. These trends reveal a clear shift: buyers now want transparent, verified, and high-impact credits.

As competition heats up, major players and new platforms are doubling down on quality. Because of this, buyers must choose trusted exchanges that offer verified, high-integrity carbon credits. Below, we break down why prices are rising, what trends are driving demand, and where buyers can find reliable credits in today’s fast-changing market.

Why Carbon Credit Prices Are Climbing in 2025

The 2025 carbon market looks very different from previous years. More than 95 million credits were retired in the first half of the year alone, according to Sylvera. This was the highest six-month total ever recorded. The surge reflects stronger climate action from governments and companies facing stricter rules.

Prices show the same direction. Carbon credits today cost 1.9 times more than in 2018. Demand for high-quality offsets hit new highs, while the supply of credible, recent credits remains tight.

Premium Credits and Removals Capture Big Margins

High-rated credits led the price jump. In 2025, “investment-grade” credits—rated BBB or higher—averaged $14.80 per ton. Lower-rated credits averaged just $3.50. Buyers also paid more for newer credits. According to Ecosystem Marketplace, premiums for credits issued in the past five years reached 217%, up from 53% in 2023.

Carbon removal credits, such as reforestation or direct air capture, gained even more momentum. These credits now trade at a massive 381% premium over traditional reduction credits.

Although prices still vary—sometimes by 11% between credits from the same project—buyers show rising confidence. New standards, such as the ICVCM’s Core Carbon Principles and updated regulations, are making integrity a priority.

Why High-Quality Carbon Credits Are in Such High Demand

Demand for trustworthy credits keeps rising due to tighter rules, corporate pressure, and growing public scrutiny. Programs like CORSIA, the global aviation offsetting system, now require stricter eligibility. In the first half of 2025, more than one-third of all new credits issued were potentially eligible for CORSIA Phase 1, depending on Article 6 approvals.

The Science-Based Targets initiative (SBTi) also pushed companies to use only high-integrity carbon removals for net-zero claims. As a result, businesses are moving away from cheap, low-quality credits. Instead, they are paying more for offsets that deliver proven climate and community benefits.

Technology-based removal credits—such as direct air capture—saw some of the highest prices in the market, often above $1,000 per ton. Nature-based credits remained important but typically traded between $7 and $24 per ton. This widening gap shows how buyers value durability and innovation.

The Top 7 Platforms to Buy Verified Carbon Credits in 2025

Because transparency matters more than ever, selecting the right exchange is essential. Here are seven reliable platforms offering verified carbon credits in 2025:

carbon credit companies

All these platforms work with leading standards bodies like Verra, Gold Standard, and the American Carbon Registry to ensure strong credibility.

How New Standards and Market Forces Are Reshaping 2025 Prices

Integrity-focused reforms, new technologies, and shifting buyer behavior continue to reshape the carbon market. According to the World Bank, new standards have led to fresh price swings—especially for high-quality nature-based credits. Issuances hit record highs, too.

  • Sylvera reported that 77 million credits were issued in Q2 2025, up 39% from Q1 and 14% from Q2 2024. Yet retirements grew even faster, keeping pressure on supply.

Old vintage credits are quickly falling out of favor. Companies now want recent, high-quality offsets that meet new regulatory and investor expectations. As a result, BBB-rated credits and other premium assets are setting the tone for market pricing.

Some older credits still trade below $1 per ton, but high-integrity projects now define the market’s direction and future values.

What the Latest Data Says About Growth and the Road Ahead

The numbers reveal a market growing fast and evolving even faster. BloombergNEF’s High Quality scenario shows potential supply rising from 243 million tons in 2024 to 2.6 billion tons by 2030, and possibly 4.8 billion tons by 2050. Even with rising supply, prices are expected to climb.

  • BNEF forecasts an average of $60 per ton by 2030, increasing to $104 per ton by 2050 as demand for removals outpaces reduction credits.

Notably, Direct air capture will play a major role. By 2050, BNEF expects it to supply 21% of all carbon credits, helping push average prices above $100.

Market structure is also shifting. Bilateral (over-the-counter) deals have exploded—growing 27-fold since 2022—as buyers want tailored, audited solutions. Compliance markets, like those in Singapore and California, continue to raise prices through strong tax and allowance policies.

The Bottom Line for 2025 and Beyond

The carbon market is moving toward a future defined by quality, transparency, and impact. Demand is rising fast, regulations are tightening, and buyers are paying more for verified, high-integrity credits.

In this new environment, the best opportunities will favor informed buyers—those who act early, choose reputable platforms, and prioritize integrity over volume. The road to net zero increasingly depends on credible, premium carbon credits that deliver real climate results.

What the IEA’s New Scenarios Mean for the Global Climate — and for COP30

Published

on

The energy world is changing fast, yet not fast enough to protect the planet from dangerous warming. The International Energy Agency’s (IEA) World Energy Outlook 2025, released at the start of COP30 in Brazil, lays out three futures for global emissions. These scenarios show how close — or far — the world is from meeting the goals of the Paris Agreement. The findings are sobering, but they also give countries clear signals on where action must accelerate.

The IEA makes one point very clear: 2024 was the hottest year ever recorded, and for the first time, global temperatures stayed above 1.5°C across the entire year. The last decade was also the hottest in history. This puts huge pressure on countries as they update their national climate plans at COP30.

Yet the IEA also stresses something important — none of its scenarios are forecasts. They are pathways, and the direction we take still depends on policy choices made today.

A World on a Hotter Track: What the IEA’s Scenarios Show

The IEA’s three major scenarios outline different ways the global energy system could evolve. Two reflect today’s conditions. The third shows what it would take actually to reach net-zero emissions by 2050.

Global energy demand
Source: IEA

Current Policies Scenario (CPS): The Dangerous Path

This scenario assumes governments stop at policies already written into law. No new climate pledges. No new incentives. No strengthened targets.

Under this path:

  • Coal use falls only slightly.
  • Oil and gas demand have been rising for decades.
  • Global energy-related emissions stay close to 2024 levels all the way to 2050.

The result is alarming. Global warming will hit 2°C by around 2050 and reach 2.9°C by 2100, and temperatures will still be rising. The IEA even warns there is a 5% chance of hitting 4°C, a level associated with extreme climate disruptions and irreversible tipping points.

The CPS was removed after 2020 because it seemed unrealistic in a world trying to cut emissions. But political pressure, especially from the Trump administration, pushed the IEA to bring it back. Its return shows how vulnerable global climate ambition can be when big economies shift direction.

Stated Policies Scenario (STEPS): Better, but Still Off-Track

This scenario reflects what governments say they plan to do — but not what they have legally locked in.

Here:

  • Emissions peak within a few years.
  • They fall slightly to 35.2 gigatonnes (Gt) in 2035.
  • Advanced economies and China reduce emissions.
  • But developing economies emit more as energy demand rises.

Even with these changes, the STEPS pathway still results in 2.5°C of warming by 2100. This is far above the Paris goal of “well below 2°C” and nowhere near keeping warming under 1.5°C. The IEA notes that this year’s STEPS outcome is worse than last year’s due to slower clean energy progress and higher expected coal use.

Net Zero by 2050 Scenario (NZE): The Only Path that Stabilizes the Climate

Net Zero by 2050 Scenario, often called the NZE, shows what a 1.5°C-aligned future would require. It is the only pathway that eventually brings warming back below 1.5°C by the end of the century.

But the challenge has grown sharply. Because real-world emissions remain high, the NZE scenario now includes:

  • a higher and longer overshoot of the 1.5°C limit
  • warming peaks around 65°C mid-century and slowly declines

Large-Scale Carbon Removal Technologies: The Saviour

The only way to return below that threshold later this century is to combine deep emissions cuts with large-scale carbon removal technologies. These technologies remain expensive and unproven at the scale required.

So the IEA emphasizes that countries must do everything possible to limit the overshoot by cutting emissions faster now. Notably, in the NZE pathway, global emissions fall by more than half by 2035 and reach net zero by 2050.

By the end of the century, carbon removal technologies would need to eliminate nearly four gigatonnes of CO₂ each year to bring temperatures back down.

A Fossil Peak Nears as Clean Energy Surges — but the World Still Falls Short

The IEA shows the energy system shifting, with coal already at or near its peak and oil expected to peak around 2030, though its decline will be slower than once expected. Gas demand levels off around 2035, but at a higher baseline than earlier forecasts, revealing how deeply rooted fossil fuels remain in the global mix.

At the same time, clean energy is rising fast. Solar capacity could more than triple by 2035, wind is set to nearly triple, and nuclear expands by close to 40 percent. Renewables will even overtake oil as the largest energy source by the early 2040s. Yet the world is still not moving fast enough. Under stated policies, renewable capacity reaches about 13,700 gigawatts by 2035, far short of the roughly 19,600 gigawatts required under the net-zero pathway.

Global Carbon Emissions: Peaks and Plateaus

Both IEA scenarios point to sustained high emissions, though at different levels. In the CPS, global energy emissions stay near 2024 levels through 2050, as small coal reductions are offset by rising oil and gas use. In the STEPS, emissions peak soon, drop to 35.2 gigatonnes by 2035, and decline slowly to 2050.

Reductions in advanced economies and China are balanced by rising emissions in developing regions. The gap between CPS and STEPS comes mainly from higher coal emissions, slower industrial efficiency, and delayed adoption of electric and efficient vehicles.

All in all, this gap underscores the need to accelerate clean energy deployment to align with global climate goals.

Why COP30 Matters More Than Ever

With the world heating faster than expected and the 1.5°C threshold already breached annually, COP30 becomes a turning point. The IEA’s outlook directly shapes negotiations because it:

  • Shows the world is far off-track.
  • Highlights the widening gap between political promises and real action.
  • Makes clear that overshoot is now unavoidable.
  • Warns that delay will force much heavier reliance on expensive CO₂ removals later.

At COP30, countries need to submit new Nationally Determined Contributions (NDCs). The IEA warns that current NDCs do not reflect the full potential of national policies or domestic clean energy momentum. In other words, many countries are doing more at home than they are willing to commit to on paper.

COP30 is a chance to fix this gap.

What Can Be Done to Get on Track? The IEA’s Priority Actions

The message is clear: the world is not on track, and the window to avoid the worst climate impacts is shrinking. Still, the IEA shows that meaningful progress is underway.

It highlights several actions that could quickly bring global emissions closer to the NZE path. The world needs faster renewable energy deployment, stronger energy efficiency improvements, and large reductions in methane emissions from the energy sector.

Electrification of vehicles, buildings, and industry has to accelerate, and sustainable fuels such as biofuels and hydrogen must expand significantly. These steps are well understood, often cost-effective, and achievable with current technology. What remains missing is the political will to scale them up at the speed required.

With COP30, countries certainly have an opportunity to match ambition with action and take decisive steps toward a safer climate future.
