Stripe’s climate initiative is a gift because it removes all barriers to positive action. This program makes it easy, and valuable, to do the right thing. We’re proud to be part of it.
There’s huge potential for Stripe Climate to drive meaningful change in protecting the environment. We're excited to be part of it and to help unlock new solutions to humanitarian and environmental issues.
Stripe Climate is Stripe at their 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.
Stripe’s concept for leveraging technology for climate change – aggregating small actions into significant impact – resonates deeply with us. The combination of ease and rigor made Stripe Climate 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.
Seachange leverages the power and scale of the world’s oceans to remove carbon. Their 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. Their 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 nearly limitless.CaptureStorage
CarbonCure injects CO₂ into fresh concrete, where it mineralizes 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 stabilizes it as limestone on the seafloor.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
