Carbon removal

Carbon removal actively removes CO₂ from the atmosphere. It uses methods ranging from nature-based to completely engineered.

Removal methods

*We use different projects for each methods composing your carbon removal. The projects used in your removal may vary based on availability.

Direct Air Capture

€€€EUR 700-900 / Ton

Direct Air Capture uses large fan-like machines to pull CO directly out of the atmosphere. Captured CO can either be stored permanently in rock formations underneath the earth’s surface or reused for other materials.


€€€EUR 500-600 / Ton

By heating up biomass to extremely high temperatures without oxygen, carbon is locked up in bio-oil. This carbon-rich material can then either be stored away permanently underground or be refined and used as a green energy source.

Enhanced Weathering

€€EUR 150-400 / Ton

Enhanced weathering is a nature-based carbon removal solution that enhances CO₂ absorption by the ocean. When applying olivine-containing rock onto coastlines, it dissolves in seawater, which increases ocean's CO₂ uptake.

Ocean Blue Carbon

€€EUR 150-250 / Ton

Ocean Blue Carbon is a method that taps into the carbon sequestration potential of ocean biomass. CO₂ is permanently removed from the atmosphere by transporting seaweed to the middle of the ocean and sinking the carbon-rich biomass to its depths.


€€EUR 125-175 / Ton

Heating waste biomass to high temperatures without oxygen turns it into carbon-rich biochar. Applied to soils, biochar is great for storing carbon for a long time while simultaneously increasing agricultural productivity.

Soil Sequestration

EUR 30-60 / Ton

Soils are great at capturing carbon, but the overuse of soils over the past decades has reduced their ability to do so. Diverse techniques can optimize and help regain the carbon-capturing properties of soils.


EUR 20-50 / Ton

Trees are the earth’s natural carbon removal machines. Trees sequester CO₂ using photosynthesis and store it in every part of the tree. A single tree can capture up to a ton of CO₂ in its lifetime.

Coastal Blue Carbon


Coastal blue carbon is the carbon stored in coastal ecosystems, such as mangroves, seagrass meadows, tidal marshes, and shellfish reefs. Carbon is stored in plant biomass and the associated soils and sediments of these ecosystems.


€€€EUR 300-500 / Ton

BECCS involves the combustion of biomass to create carbon-neutral bioenergy and the subsequent capture of the CO₂ produced. The CO₂ is then permanently stored in underground formations, resulting in a net carbon-negative impact.

Carbon Removal Projects

We work with the best carbon removal projects

from around the world to create global impact

Our evaluation framework

Thorough analysis ensures the

highest-quality carbon removal

We analyse projects by looking at four overarching parameters and assess each project using 158 data points.

Climate impact

36 data points

Klimate evaluates the permanence, rapidity and additionality of carbon removal projects to determine the impact they have on climate change.


To ensure genuine and credible carbon removal credits, a project must be 'additional' to what would have happened if the project had not been carried out (the "business-as-usual" scenario).


To effectively sequester and store carbon, the energy, land and water consumption of carbon removal projects must be as low as possible.


Carbon removal projects reduce climate change by removing atmospheric CO₂ , storing it in reservoirs, and preventing it from being re-emitted. The more permanent a removal is, the longer it keeps carbon locked away in reservoirs.


The time period between emissions occurring and carbon removal projects sequestering those emissions (in various reservoirs) affects how much emissions contribute to climate change. Faster reductions mean less warming from CO₂.


50 data points

Beyond carbon removal, we evaluate the social and environmental benefits that carbon removal projects generate.


Carbon removal projects can generate environmental benefits, such as biodiversity or clean air. But they can also cause environmental harm, such as waste, pollution, or biodiversity loss. Both aspects must be considered.


Resulting from its activities, carbon removal projects can generate social benefits, such as jobs and welfare. But they can also cause social harm, such as loss of livelihood or noise pollution. Both aspects must be considered.


34 data points

Klimate analyses the accounting, certification standards, and verification procedures of carbon removal projects to ensure sound and credible projects.


Carbon removal projects must include systems to properly measure and account for the CO₂ emissions sequestered and stored. This enables traceability and fosters transparency, building credibility in carbon removal projects. Accounting builds on specific measurements and typically follow established procedures, such as life-cycle assessment.


Carbon removal projects must have procedures in place to ensure and verify the removal of CO₂ emissions. Projects can follow certification standards, such as Verra, or various technology-specific procedures. In addition, projects might include tailored solutions, such as blockchain.


By rigorously assessing projects, certification standards help ensure the integrity of carbon removal projects. Certification standards include well-defined methods for monitoring, reporting, verifying, and auditing projects.


Carbon removal projects monitor the carbon sequestration and storage to ensure integrity and demonstrate impact. Projects can use technological solutions, such as satellites and artificial intelligence, and sometimes also monitor co-benefits, such as biodiversity impacts.


38 data points

We analyse the potential benefits and risks of the carbon removal projects and technologies to future-proof your investments.


Carbon removal projects differ on many fronts, utilising nature-based, technical or hybrid solutions. These differences cause projects and technologies to have different potentials for scale and scope, which should be considered.

Risk / Mitigation

Carbon removal projects carry inherent risks, both natural and man-made. These must be evaluated and mitigated to ensure the lowest possible risk of carbon removal projects not delivering on their promise of removing CO₂.


Governance means the system and procedures by which a supplier and its projects is controlled and operated. It also includes the mechanisms and policies for holding the company accountable for its actions and outcomes. Elements of governance include ethics, risk management, compliance and administration.


The Sustainable Development Goals consist of 17 goals and 169 targets that strive to eradicate poverty and realize a sustainable world by 2030. Each carbon removal project is measured on how it contributes to the fulfillment of one or more of the 17 goals.

Why carbon removal?

Real net zero requires carbon removal

A lot of companies rely on avoided emissions for offsetting their emissions. Credits from renewable energy or cookstoves result in a reduction of a future emission, but the Net Emission is still the same.

When using carbon removal, you are actively taking CO from the atmosphere, if you remove more than you emit, your company is Net Zero.
