The case for funding carbon removal

Carbon removal is critical to counteract climate change

To prevent the most catastrophic effects of climate change, we should aim to limit global average temperature increase to 1.5°C above pre-industrial levels, which corresponds to reducing global annual CO₂ emissions from about 40 gigatons per year as of 2018, to net zero by 2050.

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.

Path to limit global temperature increase to ~1.5°C

Historical emissions ~2°C path ~1.5°C path Current path
Carbon removal needed to limit global temperature increase to ~1.5°C.
Historical emissions via Global Carbon Project,1 "Current path" shows SSP4-6.0,2,3 removal pathways adapted from CICERO.4 For simplicity this chart only shows CO₂, though the modeled scenarios account for other greenhouse gas emissions, all of which will need to be reduced.

However, carbon removal is behind

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 adopters can change the course of carbon removal

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.

This thinking shaped our initial commitment and first purchases. If a broad coalition of like-minded buyers commits substantial investment, we’re optimistic that we can shift the trajectory of the industry and increase the likelihood the world has the portfolio of solutions needed.

Our portfolio

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.


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.


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.


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.


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.


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.
