Stripe’s climate initiative is a gift because it removes all barriers to positive action. This programme makes it easy, and valuable, to do the right thing. We’re proud to be part of it.
We need to solve climate change, but individual actions can only get us so far. Because we’re a small team we’re very focused on our core product, so it was an easy decision to join the growing group of companies using Stripe Climate.
Stripe Climate is Stripe at its best: taking something hugely complicated, doing all the work to boil it down to something understandable, and making it as easy as possible for us to be a part of it.
A lightbulb went on for us after we read about Stripe’s initial carbon removal commitment. Being a team of meteorologists, we’re especially concerned about climate change, so signing up to support next-generation climate technologies was a no-brainer.
To accomplish this, the world will likely need to both radically reduce the new emissions we put into the air, and remove carbon already in the atmosphere.
Existing carbon removal solutions such as reforestation and soil carbon sequestration are important, but they alone are unlikely to scale to the size of the problem. New carbon removal technologies need to be developed – ones that have the potential to be high volume and low cost by 2050 – even if they aren’t yet mature.
Today, carbon removal solutions face a chicken-and-egg problem. As early technologies, they’re more expensive, so don’t attract a critical mass of customers. But without wider adoption, they can’t scale production to become cheaper.
Early purchasers can help new carbon removal technologies get down the cost curve and up the volume curve. Experience with manufacturing learning and experience curves has shown repeatedly that deployment and scale beget improvement, a phenomenon seen across DNA sequencing, hard drive capacity and solar panels.
We work with a multidisciplinary group of top scientific experts to help us find and evaluate the most promising carbon removal technologies. Explore our growing portfolio of early-stage carbon removal projects, read the criteria we use to select them, or view our open sourced project applications.
44.01 turns CO₂ into rock, harnessing the natural power of mineralization. Their technology injects CO₂ into peridotite, an abundantly available rock, where it is stored permanently. This storage approach can be paired with a variety of capture technologies.Storage
Ebb Carbon mitigates ocean acidification while capturing CO₂. Using membranes and electrochemistry, Ebb removes acid from the ocean and enhances its natural ability to draw down CO₂ from the air for storage as oceanic bicarbonate.CaptureStorage
Eion accelerates mineral weathering by mixing silicate rocks into soil. Their pelletized product is applied by farmers and ranchers to increase carbon in the soil, which over time makes its way into the ocean where it’s permanently stored as bicarbonate. Alongside their technology development, Eion is also conducting a novel soil study to improve the field's measurement of CO₂ uptake.CaptureStorage
Sustaera uses ceramic monolith air contactors to capture CO₂ directly from the air for permanent storage underground. Their direct air capture system, powered by carbon-free electricity and built with modular components, is designed for quick manufacturing and capture at scale.CaptureStorage
Seachange leverages the power and scale of the world’s oceans to remove carbon. Its experimental electrochemical process sequesters CO₂ in seawater as carbonates, an inert material comparable to seashells, thereby enabling energy-efficient and permanent CO₂ removal.CaptureStorage
Running Tide removes carbon by growing kelp in the open ocean. After maximum growth, the free-floating lines of kelp sink to the deep ocean where the embodied carbon is stored for the long term. Running Tide’s approach is simple and scalable, powered by photosynthesis, ocean currents and gravity.CaptureStorage
Over geological timescales, CO₂ chemically binds to minerals and permanently turns to stone. Heirloom is building a direct air capture solution that enhances this process to absorb CO₂ from the ambient air in days rather than years, and then extracts the CO₂ to be stored permanently underground.CaptureStorage
Mission Zero electrochemically removes CO₂ from the air and concentrates it for a variety of sequestration pathways. Its experimental room-temperature process can be powered with clean electricity and has the potential to achieve low costs and high volumes using modular, off-the-shelf equipment.CaptureStorage
CarbonBuilt’s process readily converts dilute CO₂ into calcium carbonate, creating a “no compromise” low-carbon alternative to traditional concrete. As a profitable and scalable solution for permanent CO₂ storage, CarbonBuilt’s technology platform can serve as a critical component of future carbon removal systems using direct air capture.Storage
Future Forest is conducting a field trial to accelerate mineral weathering by crushing basalt rocks into dust, spreading them onto the forest floor, and then measuring CO₂ uptake. This first-of-a-kind trial will help assess the potential for scale as well as the potential ecosystem impacts associated with enhanced weathering.CaptureStorage
Climeworks uses renewable geothermal energy and waste heat to capture CO₂ directly from the air, concentrate it, and permanently sequester it underground in basaltic rock formations with Carbfix. While it’s early in scaling, it’s permanent, easy to measure, and the capacity of this approach is theoretically almost limitless.CaptureStorage
CarbonCure injects CO₂ into fresh concrete, where it mineralises and is permanently stored while improving the concrete’s compressive strength. Today they source waste CO₂, but represent a promising platform technology for permanent CO₂ storage, a key component of future carbon removal systems.Storage
Project Vesta captures CO₂ by using an abundant, naturally occurring mineral called olivine. Ocean waves grind down the olivine, increasing its surface area. As the olivine breaks down, it captures atmospheric CO₂ from within the ocean and stabilises it as limestone on the sea floor.CaptureStorage
Charm Industrial has created a novel process for preparing and injecting bio-oil into geologic storage. Bio-oil is produced from biomass and maintains much of the carbon that was captured naturally by the plants. By injecting it into secure geologic storage, they’re making the carbon storage permanent.CaptureStorage
