How Frontier works

Frontier is an advance market commitment (AMC) that aims to accelerate the development of carbon removal technologies by guaranteeing future demand for them. The goal is to send a strong demand signal to researchers, entrepreneurs, and investors that there is a growing market for these technologies.

Importantly, Frontier aims to grow global supply by helping the most promising carbon removal projects deliver, rather than compete over what exists today. In practice, its team of technical and commercial experts facilitates purchases from high-potential carbon removal companies on behalf of buyers. There are a variety of ways that buyers can participate in Frontier as a part of their climate program.

The concept of an AMC is borrowed from vaccine development and was piloted a decade ago. The first AMC accelerated the development of pneumococcal vaccines for low-income countries, saving an estimated 700,000 lives.

While the market dynamics of carbon removal and vaccines are not identical, they face similar challenges: uncertainty about long-term demand and unproven technologies. AMCs have the power to send a strong and immediate demand signal without picking winning technologies at the start.

1 | Frontier aggregates demand to set an annual maximum spend

Buyers decide how much they want to spend on carbon removal each year. Frontier aggregates commitments to set a total annual demand pool. Suppliers apply for consideration.

2 | Frontier vets suppliers and facilitates carbon removal purchases

For early-stage suppliers, agreements will likely take the form of low-volume prepurchases. For larger suppliers ready to scale, Frontier will facilitate offtake agreements to purchase future tons of carbon removal at an agreed price if and when delivered.

3 | Suppliers remove carbon and pass tons back to buyers

When tons of carbon are removed, suppliers get paid. In the case of offtake agreements, tons are issued back to buyers.

Focusing on scalable, permanent solutions

We look for permanent carbon removal solutions that have the potential to be low-cost and high-volume in the future, even if they’re not today. Specifically, Frontier will focus on technologies that meet the following criteria:

Criteria Description
DurabilityStores carbon permanently (>1,000 years)
Physical footprintTakes advantage of carbon sinks and sources that do not compete for arable land
CostHas a path to being affordable at scale (<$100 per ton)
CapacityHas a path to being a meaningful part of the carbon removal solution portfolio (>0.5 gigatons per year)
Net negativityMaximizes net removal of atmospheric carbon dioxide
AdditionalityResults in net new carbon removed, rather than taking credit for removal that was already going to occur
VerifiabilityHas a path to using scientifically rigorous and transparent methods for monitoring and verification
Safety & regulatoryIs working towards the highest standards of safety, compliance and local environmental outcomes; actively mitigates risks and negative environmental and other externalities on an ongoing basis

Carbon removal needs a bold assist

To avoid the worst effects of climate change, most climate models agree it won’t be enough to just reduce emissions. We’ll also need to remove gigatons of carbon dioxide already in the atmosphere.

Carbon removal has made significant progress over the past few years. Hundreds of companies are being built, and tens of thousands of tons have been delivered. But the field is still nowhere near the scale required.

We need a gigaton-scale portfolio of permanent carbon removal solutions, and the market to get them there. An AMC gives the industry the confidence to keep building, and to do so with urgency.

Q&A

How many tons of removal will Frontier members buy?

We don’t know yet. Frontier will target technologies that are high quality and have the greatest long-term potential, rather than what is cheap today. For that reason, we don’t know in advance how many tons we’ll be able to buy, or what the price per ton will be. Tons contracted and delivered to date are tracked on our dashboard.

Do buyers get a return?

No. Frontier will facilitate purchases of carbon removal on behalf of buyers. It won’t make or facilitate equity investments at this time.

Can additional companies buy through Frontier?

Yes, we welcome new companies to participate in Frontier. Learn about your options to participate.

How is Frontier governed?

Frontier is a public benefit LLC wholly owned by Stripe LLC. It is run by a dedicated team of technical and commercial experts, led by Hannah Bebbington Valori, on behalf of buyers. Frontier founders serve on the Board, which oversees the high-level objectives of Frontier’s activities. Frontier is also advised by a multidisciplinary group of industry experts.
