The CEEZER Carbon Coalition—
start commercializing.

Fight for a net-zero economy—together.

Mission

The CEEZER Carbon Coalition program empowers start-ups in the voluntary carbon market and bridges the gap between ideation and commercialization. The program addresses the challenges typically faced by project developers, such as increasing buyer awareness, understanding buyer needs, and navigating MRV, registries, inventory management, and pricing. After several successful editions focused on durable carbon dioxide removal (CDR) technologies, we're thrilled to expand CEEZER's Carbon Coalition with a new edition of the program focused on carbon removal projects from nature-based solutions.

The fight for a net-zero economy requires a united effort. We believe growing the VCM and scaling promising, early-stage developers is vital to accelerate global carbon removal efforts. This includes championing emerging durable (CDR) technologies and nature-based solutions. Through the Carbon Coalition, CEEZER supports ambitious startups to enter the market, and onboards innovative, high-quality projects directly onto the CEEZER platform.

Whether your solution is nature-based or tech-based, if you have a bold, viable approach to carbon removal, we want to hear from you.

Collaborate to scale impact—starting now.

Who should apply

The durable CDR edition is tailored to:

Innovators in durable carbon removal.
Early-stage project developers pursuing unique approaches or venturing into new project types, such as biochar, enhanced rock weathering, mineralization, or direct air capture.
Proven proof of concept with operational pilot projects.
Projects not yet issuing carbon credits but keen on contributing to the carbon market ecosystem.
A clear pathway to certification.

The nature-based solutions edition is tailored to more mature project developers. If the following applies to you, we want to hear from you:

Projects in certification under an ICROA-endorsed registry.
Project developers implementing nature-based solution programs, including blue carbon, afforestation, reforestation, and soil carbon—we're interested in all the ways nature can remove carbon.
Projects with a robust project plan and high environmental and social standards.

CarbonIn Earth

CarbonIn Earth is pioneering Biomass Fossilization, a low-cost, highly durable, breakthrough carbon removal solution that locks biomass waste into permanent storage by replicating natural fossilization.

Circular Impact

Circular Impact partners with Regen Organics to convert sugarcane bagasse into biochar before blending it into Regen Organics' existing organic fertilizer products, scaling carbon removal while enhancing soil health through biochar-infused organic fertilizers.

Neolithe

Neolithe’s proprietary Accelerated Waste Fossilization technology transforms non-recyclable, non-hazardous waste residues into “Anthropocite” aggregates to reuse in the construction sector as a substitute for natural quarried aggregates.

Releaf

Releaf specializes in producing premium biochar from waste nut shells for smallholder yield improvement and carbon sequestration. Its patented method of biomass collection has enabled Releaf to become the largest nut de-sheller in the region.

Sinkco Labs

Sinkco Labs harnesses the untapped potential of the seafloor to deliver safe, permanent, and scalable carbon storage while improving coastal resilience.

HyveGeo

HyveGeo greens the desert to remove CO₂ from the air while boosting food security in arid regions. It turns locally-sourced agricultural residue into a biochar-based formulation that regenerates desert sand into arable land and locks carbon in the soil.

Stack Carbon

Stack Carbon’s ERW project leverages the natural mineralization process to sequester CO₂ while enhancing soil health and supporting local communities.

ZeroEx

ZeroEx develops high-quality, regionally focused enhanced rock weathering projects to sequester CO2 and improve smallholder farmer livelihood.

AirSmat

AirSmat AI-driven Agtech democratizes the production of high-quality biochar to sequester carbon and improve the farmer livelihood across Africa.

SeaO2

SeaO2 develops Direct Ocean Capture technology to sequester CO2 through a scalable and cost-effective electrochemical reaction.

PRONOE

Pronoe develops water treatment systems that integrate downstream of coastal industry, using the oceans natural ability to capture and remove CO2.

Heimdal

Heimdal develops novel limestone-based direst air capture units aiming to scale operations to 1,000,000 metric tons by 2027-2029.

Silica

Silica permanently sequesters CO2 and improves crop yields for smallholder farmers through enhanced rock weathering.

RECOAL

RECOAL converts waste biomass into hydrochar, also known as Negative Emission Coal (NEC). A patented process ensures that the NEC is permanently stored.

InPlanet

InPlanet develops enhanced rock weathering projects in the tropics directed to farmers from aggregate industries’ residuals.

Green Sequest

Green Sequest develops enhanced rock weathering from serpentinite, a rock characterized by a great ability to capture and permanently store CO2.

Ucaneo

Ucaneo develops a pioneering direct air capture technology that mimics the human lung to remove CO2 from the air.

Reverse Carbon

Reverse Carbon develops biochar carbon removal projects. The biochar is sequestered in deep repositories to enable fast scaling and maximize storage durability.

Blusink

Blusink is a novel marine carbon removal and seafloor restoration method relying on biomaterial to harness the power of coralline algal growth.

Cotierra

Cotierra pushes the frontier of decentralized biochar production, focusing on small coffee and cacao farmers in South America.

Carbonsate

Carbonsate captures CO2 through photosynthesis and biomass storage, turning waste wood into carbon removal credits.

Any questions?
We have answers.

What does the application process look like?

Our application process is straightforward and designed to identify projects with the greatest potential. When the application window opens, you will have to complete our application form and provide details on your project’s scope and impact. Don’t hesitate to get in touch with us, and we'll guide you through the steps.

What is the cost of the program?

The CEEZER Carbon Coalition is free of charge for project developers. We will receive guidance from CEEZER and external experts at no cost.

Who qualifies for the CEEZER Carbon Coalition program nature-based solutions edition?

Suppliers that are currently certifying their project under an ICROA-endorsed registry with a robust project plan.

Will your nature-based solutions project be visible to buyers?

Yes, the project will go through our eligibility check to make sure it aligns with our quality thresholds and be visible on our platform at the end of the program for credit sale.

What type of carbon credits is the nature-based solutions program looking for?

CEEZER is interested in supporting a diversity of pathways, ranging from blue carbon, afforestation, reforestation to soil carbon. We are looking exclusively for projects which will issue removal credits.

Who qualifies for the CEEZER Carbon Coalition program CDR edition?

Any early-stage project developer with a unique and scalable durable carbon removal solution. Certification under a registry is not a requirement but should be part of the project roadmap.

Is it possible to purchase credits from CEEZER Carbon Coalition projects?

Projects graduating from our cohorts will be listed as 'Coming Soon' on our platform and are focused more on project visibility and creating early interest rather than credit sales. When your project is ready for a full listing on CEEZER, you can do your first sale.
