Historically, climate and environmental investing focused primarily on clean energy. Fossil fuel consumption was identified as a driving source of pollution, and climate investing became synonymous with renewable energy. While capital poured into decarbonizing our energy grid and reimagining transportation infrastructure, traditional consumer industries and supply chains chugged along, business as usual. As more recent research initiatives begin to illustrate the $4.5T importance of “decoupling economic growth from natural resource consumption,”1 Regeneration.VC identified an opportunity to engage and empower a key stakeholder group that has been effectively sidelined - consumers.
Today, it is difficult to ignore shifting attitudes around the clothes we buy, food we eat, and products we use. Extended producer responsibility conversations, straining global supply chains, and growing consumer awareness have aligned economic incentives for three key stakeholders – manufacturers, distributors, and consumers. Within these groups lies a chance to address the 45% of greenhouse gas emissions not addressed by efforts to transition to clean energy 2. Born of interdisciplinary design principles and championed two decades ago by an architect and chemist duo 3, the circular economy offers a framework to innovate consumer products and supply chains with renewed appreciation for our natural ecosystems
The circular economy has been around far longer than most folks recognize. The greatest designer of all time, Mother Nature, exemplifies circularity; living systems have evolved to symbiotically consume, reuse, and coexist 4. Product lifetime extension, sharing economies, and design for disassembly are example tenets of a framework that prioritizes waste reduction and resource management.
Post-Industrial Revolution, humans have experienced difficulty replicating the circular lifecycles most natural systems exhibit. Today, over 90% of the materials we produce end up polluting native ecosystems 5; one-third of the global food supply is tossed 6; and fashion & textiles are accountable for 20% of industrial water pollution 7. Not only do these linear economy 8 outcomes threaten biodiversity and endanger other species, humankind is struggling to keep afloat in seas of our own waste and pollution. But this is not another Doomsday story. The time has come to focus our energies on cultivating circular solutions that can simultaneously close the gap for renewables and open the door to a next generation of products and materials.
Decades of international climate negotiations have produced several overarching standards that offer structure and common language for climate technology innovation. One of the most widely recognized is the concept of net-zero emissions.

Initially popularized by the Paris Agreement 9, net-zero emissions translates to minimizing the
After reducing initial emission production, there are two main techniques for handling remaining emissions: (1) natural carbon sinks like reforestation and ocean sequestration, and (2) negative-emissions technologies that fall under the carbon capture utilization & storage market. Carbon capture utilization & storage is a burgeoning space in climate tech focused on applying circular principles to curb carbon dioxide (CO2) pollution. “Carbon capture” consists of two primary techniques: “point source” and “direct air capture.” Point source refers to technologies that capture carbon at the point of emission, whereas direct air capture solutions target carbon emissions already in the atmosphere 11.

With the emissions sequestered, there are two paths for next steps: repurpose the emissions (“utilization”) or find the emissions a permanent home (“storage”). As a global pollutant carbon dioxide 12 can be found in any region on Earth. Today, three main channels exist for circulating captured carbon dioxide. The first is carbon uptake. Feeding excess carbon dioxide to hyper-efficient photosynthetic organisms like algae can produce biofuels, fertilizers, and food. The second option is a process called mineralization. Carbon dioxide can mineralize with alkaline reactants to produce materials like cement and other inorganic bicarbonates. Third, carbon dioxide can be chemically upcycled into new materials including biofuels, bioplastics, carbon fibers, and plenty more that we will get to soon 13.
'The New Language of Carbon': Early pioneer of the circular carbon economy and Regeneration.VC Strategic Advisor, Bill McDonough has fought for years to share a more insightful perspective on carbon management. From McDonough's viewpoint, carbon emission reduction strategies and global taxonomies present a misleading framework that positions “carbon” as an enemy. In contrast, McDonough delineates carbon emissions as a byproduct of linear production (“fugitive carbon”), input for circular economies (“durable carbon”), or a safe component of natural ecosystems (“living carbon”). Not only is this positioning more informative of the essential role carbon already plays, it presents an exciting circular opportunity to repurpose waste (emissions) and buy Earth time to regenerate.
CCUS solutions hold massive potential to help achieve net zero emissions targets. The Center for Climate and Energy Solutions estimates that CCUS technology “can achieve 14% of the global greenhouse gas emissions reductions needed by 2050 (~1.4Gt annually) and is viewed as the only practical way to achieve deep decarbonization in the industrial sector.” According to the International Energy Agency, current carbon capture technology has the capacity to sequester 40 MtCO2, annually – approximately triple 2010 capacity. Putting that figure in perspective, global fertilizer production uses ~125 MtCO2 annually. Looking forward, the CCUS market is expected to grow at a 13.8% CAGR and pass $7B by 2030. As the U.S. currently employs about 75% of the global carbon capture capacity to support enhanced oil recovery – a seemingly redundant use of this technology from the climate’s perspective – the CCUS market is evidently nascent. We believe this market is poised for explosive growth as compelling use cases emerge and regulatory tailwinds align with international climate goals.
As an early-stage climate tech investment firm, Regeneration.VC has screened a number of promising carbon capture technology businesses, the most promising of which goes by the name of CleanO2 Carbon Capture Technologies (“CleanO2”), the first Regeneration.VC portfolio company. This small team in Alberta, Canada leveraged expertise in commercial property infrastructure to build patented carbon capture property technology, dubbed the “CarbinX” unit. Targeting the majority of 6M commercial & industrial North American properties using natural gas heating, CleanO2 retrofits HVAC systems with their CabinX unit to capture up to ~9 Mt CO2 (20,000lbs) and reduce energy consumption up to 20% through heat transfer, annually. The company chemically sequesters emissions into a non-toxic carbonate which is added to their premium handmade soaps, other cleaning products, and even fertilizers. Beyond this consumer application, potassium carbonate is a valuable global commodity with conventionally energy and water-intensive production methods.
“CleanO2 aims to lead the market with green chemistry approaches to consumer goods that support efforts to create a circular economy and decarbonize the HVAC industry. I see the CCUS industry in the same position that personal computing was in the ‘80s. In the not-so-distant future, we will see carbon-restrictive technologies become commonplace in every sector.”

Additional businesses that crossed our desks included: Air-Ink*, whose proprietary technology converts sequestered air pollution into black inks, Air Company, which uses electrolysis to convert carbon emissions into spirits and perfumes, and Twelve*, another electrolysis approach converting emissions into industrial materials and fuels.
* Both businesses collaborated with Regeneration.VC portfolio company, Pangaia. See Air-Ink capsule here. See Twelve capsule here.
Three indicators show that scaled CCUS solutions are not far-off: (1) the market opportunity is large and growing fast, (2) this technology is necessary to achieve global climate targets, (3) there is already an array of boundary-pushing ventures in this ecosystem. While clean energy providers vie to optimize their technologies, scale energy grid infrastructures, and fend off oil & gas lobbying efforts, fugitive carbon continues to further planetary degradation. We need the help of a rich ecosystem of ambitious innovators, researchers, and regulators to reimagine carbon emissions – viewed not as an enemy, but a valuable circular input and naturally abundant resource. Without this circular economy collaboration, net zero may forever remain out of reach. Imagine… your next bar of soap, sunglasses, or t-shirt just might help move the needle.
