The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), launched by the International Civil Aviation Organization (ICAO), plays a major role in helping airlines offset their emissions and meet climate goals.
International air travel is bouncing back after the pandemic. This drives a surge in demand for carbon credits under CORSIA. A new report by Allied Offsets forecasts strong growth in both demand and prices of eligible carbon credits from 2025 through 2035.
This article explores the latest trends, price scenarios, and what this means for airlines, project developers, and the broader voluntary carbon market.
Rising Demand: Airlines Set to Purchase More Credits
Industry estimates say that demand for CORSIA-eligible carbon credits will hit 101 to 148 million tonnes (MtCO₂e) during Phase I (2024–2026). Demand will rise quickly in Phase II (2027–2035).
Cumulative needs are expected to be between 502 and 1,299 MtCO₂e. This will depend on how much international air traffic grows and how CORSIA expands its coverage.
This big increase comes from the rebound in international air travel and the start of Phase II in 2027. During this phase, most ICAO member countries must take part.
By 2035, demand might exceed 1 billion tonnes in high-growth scenarios. That’s about the same as the yearly emissions of a major industrialized country.
To summarize projected cumulative demand:
-
Phase I (2024–2026): 101–148 MtCO₂e
-
Phase II (2027–2035): 502–1,299 MtCO₂e
This growth presents both challenges and opportunities. Airlines need enough credits to comply with regulations. At the same time, project developers and suppliers face pressure to increase the verified supply of eligible credits.
Price Outlook: A Wide Range with Upward Pressure
The report outlines three price scenarios for carbon credits based on different market dynamics:
-
Low Scenario: Prices start at $14/tonne in a tight supply scenario and grow slowly to $25/tonne in under supply scenario.
-
Medium Scenario: Prices rise from $15/tonne to $29/tonne.
-
High Scenario: Prices climb sharply from $16/tonne to $34/tonne.

Even in the conservative case, prices show modest growth. But in the high-demand scenario, prices could grow over the next decade.
On the other hand, MSCI outlines a range of price scenarios for CORSIA-eligible carbon credits as follows:
-
Phase I (2024–2026): $18–$51 per tonne
-
Phase II (2027–2035): $27–$91 per tonne (by 2033–2035)

This price rise shows that airlines face more pressure to secure high-quality credits. This is especially true as more projects focus on long-term removal instead of just temporary avoidance.
High prices might lead some airlines to invest in sustainable aviation fuel (SAF) or insets. These options help reduce emissions in their operations.
Supply Gaps and Quality Filters
CORSIA doesn’t allow just any carbon credit. ICAO has strict rules for what qualifies — including restrictions on project start dates, crediting periods, and approved methodologies. Only credits from approved programs (like Verra, Gold Standard, and ART TREES) that meet these standards are eligible.
The report estimates that:
-
Only about 543 MtCO₂e of eligible credits will be issued by 2027.

Supply is projected to lag behind demand. Reports suggest possible deficits of 12–43 MtCO₂e in Phase I. Phase II may face even larger shortfalls. This is likely if stricter quality filters are used. These filters include co-benefits, permanence, and additionality. The exact numbers for filtered supply aren’t given, but these criteria would greatly lower the usable pool.

Currently, most eligible supply comes from avoided deforestation (REDD+) and renewable energy projects. As demand increases and quality standards get stricter, the market will likely move toward lasting carbon removal solutions. This includes methods like reforestation, biochar, and direct air capture (DAC).
Regional Insights: Where Supply Comes From
The current credit supply under CORSIA is heavily concentrated in a few countries:
-
India, China, and Brazil together account for over 50% of the available supply.
Africa has fewer CORSIA-eligible credits now. However, it is expected to grow. This growth will focus on nature-based solutions, such as afforestation and cookstove projects.
This geographic concentration means that any changes in policy, political stability, or project approvals in key countries could disrupt supply. For example, if India were to change its rules on carbon credit exports — as some officials have suggested — global supply could shrink quickly.
Interest is growing in boosting credit generation in Southeast Asia and Latin America. Many areas there have good land for reforestation and carbon farming.
Market Trends and Implications for Airlines
CORSIA credits are part of the larger voluntary carbon market. This market has attracted a lot of interest from companies and governments. According to MSCI report, voluntary carbon markets could reach $250 billion annually by 2050.

But today’s CORSIA credits are selling for far less than the cost of removing CO₂ using high-tech methods like DAC, which can exceed $300 per tonne. This price gap has raised questions about credit quality and how buyers can demonstrate real climate impact.

Some key trends include:
-
Airlines such as Delta, United, and Lufthansa are now mixing credit purchases with investments in SAF. They also support offsets from reforestation or engineered removals.
-
Programs like SBTi (Science-Based Targets initiative) encourage firms to reduce emissions. They also promote high-quality removals instead of bulk offsetting.
For airlines, this means they may need to:
-
Budget more for compliance over time
-
Diversify carbon offset portfolios
-
Communicate clearly about the credibility of their offsets
The Bigger Picture: What Comes Next
The Allied Offsets report shows that corporate buyers, like airlines, play a key role in global carbon markets. Their large, long-term offtake agreements — such as Microsoft’s 18 MtCO₂e deal with Rubicon Carbon — are shaping demand signals for the next decade.
ICAO plans to tighten CORSIA rules in future reviews. This may mean more removals and limits on older avoidance projects. This could further reduce supply and raise prices.
Policymakers can boost support for in-sector measures. This includes increasing SAF production and encouraging new removal technologies.
Airlines face challenges now. They must deal with rising prices, new rules, and increased scrutiny on carbon offsetting. In the long run, using durable carbon removals could change aviation and the climate finance system.
CORSIA is entering a critical phase. Demand is set to rise sharply. Meanwhile, supply is tightening due to stricter quality controls. As the report shows, the window to build a balanced, credible carbon market is narrowing. The next few years will shape the cost and credibility of airline decarbonization for decades to come.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.
