Why Capture6

Why Capture6

Our carbon removal solution is not about us, it’s about future generations. The decisions we make today are the building blocks of our future. 


To do this we need a long-term science based solution with a focus on circular economy, social responsibility and environmental justice.


Capture6 prioritizes our mission to increase global carbon capture while growing our business. We provide a lasting solution we can deploy now.

Why 6? Carbon is a chemical element with the atomic number 6. Our logo's hexagonal shape and the 6 in our name both represent this powerful element.

Our Framework

Capture6 has developed the SPACERS™ Framework to describe our approach to direct air capture. SPACERS™ is based on the Oxford Principles on Carbon Offsetting that calls for moving to DAC that is permanent, irreversible, and with a small physical footprint to not displace or impact local communities. SPACERS™ similarly aligns with purchase criteria from initiatives such as Frontier’s $925M USD advanced market commitment for CDR or criteria from leading DAC purchasers such as Stripe, Shopify and McKinsey.

Estimates range on the amount of CO₂ that humans must remove from the atmosphere annually to limit warming to 1.5°C or below, but all estimates target billions of tons annually. This is an enormous quantity of CO₂ – and any approach to DAC that is meaningful from a planetary perspective must have the ability to scale to billion-ton removal. Because time is of the essence with climate change, technologies should be able to scale within 10 years.

There’s little point capturing CO₂ only to cause it to be re-emitted or stored in a way that makes it vulnerable. Capture6’s process mineralizes CO₂ – locking it away irreversibly for millennia. 

Purchasers of CO₂ want a clear accounting trail that can be verified. Basic chemistry governing the relations between inputs (CO₂) and outputs (mineralized carbonates) allows us to easily quantify and prove the amount of CO₂ captured. A transparent and verifiable chain of custody and ledger prevents double-counting.

The social costs of carbon are very high and the costs of DAC must be benchmarked against the costs of inaction. The duration of carbon removal from the atmosphere determines its impact – a ton of CO₂ sequestered for one thousand years has greater value than a ton of CO₂ sequestered for 20 years. That said, the efforts that can scale and get traction quickly must be cost-effective in the near-term with the possibility of further driving the cost down over time.

Unfortunately, climate change is not the only major environmental crisis humans face. Capture6 DAC approaches are designed with co-benefits including addressing ocean acidification and air pollution. Land-based installations can improve water resources for agriculture.  Restoring planetary health as part of DAC is crucial to preventing underrepresented communities from shouldering a disproportionate burden from climate change.

Climate change is largely an unintended side-effect of the industrial revolution and the economic growth of nations. In seeking to address climate change, DAC projects must be careful not to create new negative environmental and social problems, particularly those that affect underrepresented communities. Any assessment of a DAC project must include a full life-cycle analysis of the process – also known as a cradle to grave analysis. Such an analysis must also consider the scarcity of resources the DAC project utilizes, including arable land and freshwater. 

Any DAC effort must be compliant with relevant national and international regulations. Facilities must be operated in a safe manner that actively mitigates negative impact to local environments and communities, including health and livelihoods.  As a nascent industry with often scant legal frameworks, DAC efforts must earn and maintain social license from ongoing stakeholder dialogue. As a Public Benefit Corporation, we prioritize our mission to increase global carbon capture while growing our business.

Social and Environmental Benefits

As the world races to curtail greenhouse gas emissions, carbon removal can play a critical role as a planetary insurance policy. Our vision is coupled with a focus on co-benefits and circular economy thinking.

Social Responsibility and Environmental Justice

Our approach to environmental justice is based on inclusive and equitable consideration of multiple perspectives through meaningful and iterative public engagement. We intend to develop trust with stakeholders through transparency, sharing and co-producing data, and responding to concerns. We earn social license from local communities, businesses, and indigenous communities through building consensus that the benefits we produce outweigh the negative consequences, and that the negative consequences are not unfairly distributed by amplifying voices from underserved and indigenous communities.

Mission First

As a Public Benefit Corporation, we prioritize our mission to increase global carbon capture while growing our business. We innovate systems and processes that help protect the planet for future generations. For us, that innovation goes beyond perfecting our process for CO₂ removal. It also means ingenuity in how we think about business models, pursue avenues for rapid commercialization, and form the partnerships and coalitions that can make ambitious plans happen.

Our Approach

Our DAC is one of the world’s leading solutions for permanent and irreversible carbon dioxide removal.
