PUBLIC CDR RESOURCE SURVEYS AND ATLASES

Lever last updated: 14 September 2026

Publicly funded surveys mapping where CDR materials and storage resources exist.

Cost

Very low to High

The commissioning organisation pays for data access, surveys, sampling, analysis, publication and updates. A local assessment using existing records is inexpensive; a multi-year programme of seismic surveys and test wells can require major expenditure. One-off surveys are annualised; resource development is financed separately.

Complexity

Low to Medium

An existing survey agency can analyse records through established procedures. A new programme needs access agreements, common data categories, procurement and a maintained database, particularly when combining geological, forestry and waste information.

Timeline

Short to Medium

Existing records can change developers' screening or sourcing decisions within one to two years of commissioning. New field surveys, test wells or seasonal feedstock sampling may take two to five years before results can reliably change site selection or planned project scale.

Overview

Public CDR resource surveys establish where suitable materials and storage resources may be available, then make the findings accessible to developers and planners. A government, research institution, industry association or foundation commissions teams to investigate biomass supply, reactive minerals, industrial residues or geological formations and publish maps with the supporting data. The assessment shows quantities and quality alongside competing uses, transport needs and environmental constraints. Developers can use it to compare locations and choose which require detailed investigation; authorities can use it to plan infrastructure and resource licensing. Sharing the evidence reduces repeated early research across projects. A published resource estimate gives neither ownership nor a right to use the material, land or underground space.

Key Considerations

The commissioning body should decide which practical questions the survey must answer before gathering data. Estimates need to separate total physical resources from quantities that could actually be used under stated technical, economic and environmental conditions. Biomass studies should account for existing uses, seasonality, collection losses and residues needed to protect soils. Mineral and industrial-residue studies should test composition, contamination and processing needs. Geological studies should assess reservoir quality and containment using existing well records and seismic surveys, which use sound waves to map rock structures, with new fieldwork where records are inadequate. Across these resources, maps should show transport, energy, water and land-rights constraints. Methods, uncertainty and useful underlying data should be published under clear data-sharing terms, with a named institution funded to update them.

Opportunities

Reliable shared resource information helps developers reject unsuitable locations before committing to expensive exploration, plant design or supply negotiations. A biomass assessment can reveal whether a planned biochar plant has enough suitable feedstock after existing users and soil protection are considered. Geological maps can identify formations worth testing, while mineral and residue data can show whether local materials need costly treatment. Reusing public records reduces duplicated investigation and lets smaller developers draw on evidence they could not readily commission alone. Authorities can also compare proposed projects against the same resource assumptions when planning infrastructure or licensing areas. Published methods and uncertainty allow independent experts and communities to scrutinise those assumptions. More credible site and scale choices can reduce wasted investment, although each project still needs its own technical checks, permissions and sourcing agreements.

Risks

A large headline resource estimate can be mistaken for supply that is available now. Total biomass growth does not show how much can be harvested sustainably, and underground pore space does not establish permitted injection capacity. Stale data or assumptions that ignore other users can therefore lead projects to compete for the same inputs, encourage overharvesting or leave infrastructure dependent on unsuitable sites. The assessment can also favour incumbents if publicly funded evidence is withheld from others. Conversely, releasing confidential commercial records or sensitive information about customary land use without permission can harm data providers and communities. Clear distinctions between estimated and verified resources, transparent assumptions and controlled treatment of sensitive information are necessary for a useful public assessment.

Monitoring and Evaluation

The commissioning body should ask whether developers and authorities use the assessment to change site selection, project scale, sourcing or infrastructure plans. Later investigations should be compared with the published estimates, including sites rejected after testing and feedstock supplies that proved too costly or unavailable. Actual samples, seasonal deliveries and storage tests reveal whether the methods predict usable resources. Independent experts should review repeated discrepancies and recommend revised assumptions or further surveys. Downloads show whether information is accessed; documented changes to project and planning decisions provide stronger evidence that the service is useful.

Stakeholder Engagement

Survey teams should obtain existing records from geological, forestry, agricultural, mineral and waste authorities and agree what can be released. Material suppliers and current users can test estimates of supply, competing demand and collection costs. Developers and infrastructure planners should identify the data they need to compare locations, while regulators explain the additional evidence required for permits. Independent specialists should review methods and uncertainty. Landholders, communities and Indigenous or customary-rights holders should identify access restrictions and information that needs protection. Their contribution to a survey must not be treated as agreement to a future project.

Governance Levels

InternationalSupranationalNationalRegional / StateCity / MunicipalCorporate / IndustryPhilanthropy

National and regional survey agencies can commission fieldwork and publish assessments under their geological, forestry or resource-management mandates. Municipal authorities can assess local material and waste streams. International and supranational bodies can commission shared research and datasets across jurisdictions. Industry associations and philanthropic organisations can contract research teams and publish open assessments for wider use.

Implementation Strategies

  • Commissioning bodies should organise the work through institutions with continuing geological, forestry, agricultural or resource-management mandates, starting with existing records and permission to reuse them. The first areas examined should be relevant to credible removal projects, material users and infrastructure plans.

  • Survey teams should separate theoretical resources, technically usable quantities and resources accessible under realistic economic and environmental conditions. They should publish the methods, useful underlying data and uncertainty so developers and independent reviewers can test the estimates. Storage volumes, annual feedstock flows and existing carbon stocks must remain distinct.

  • Where records are insufficient, commissioning bodies should fund new surveys in stages and stop or redirect work when results weaken an area's prospects. Priority areas should receive enough investigation to inform real choices before funding is spread across complete national coverage. Feedstock studies should test composition, collection and competing uses as well as gross quantities.

  • Survey teams should combine resource information with infrastructure, environmental and land-rights constraints without publishing sensitive community or commercial records indiscriminately. They should state what remains unverified and require project developers to obtain their own permits, consents and supply agreements.

  • The commissioning body should give the survey a continuing budget and agree how licensed projects or participating suppliers return new evidence. Comparisons with later investigations, injection results and actual material deliveries should feed into revisions, including locations or resources that proved unsuitable.

Case Studies

Norwegian CO₂ storage atlases

The Norwegian Offshore Directorate, the public authority responsible for knowledge about Norway's offshore resources, publishes CO₂ storage atlases for the North Sea, Norwegian Sea and southern Barents Sea. The North Sea assessment reused more than forty years of petroleum data to examine twenty-one geological formations, assessing the reservoir properties and the presence of rock layers that could contain CO₂. It estimated about 70 billion tonnes of potential storage; the Norwegian Sea atlas added an estimated 5.5 billion tonnes. The directorate stated that the atlas would inform storage announcements and applications, connecting the public research to licensing work. Developers can also compare formations through the interactive atlas before paying for detailed site investigations. This shows how reusing public geological records supports both government planning and private site selection. The figures describe potential underground resources, not permitted annual injection capacity; individual sites still need testing, engineering and customer access.

US Carbon Storage Atlas and regional data

The US National Energy Technology Laboratory, part of the Department of Energy, combined regional evidence in its 2015 Carbon Storage Atlas. The atlas drew on seven regional partnerships involving more than 400 organisations across 43 states and four Canadian provinces, as well as ten separately funded site-characterisation projects. It brought storage estimates together with lessons on investigation, monitoring, operation and public engagement. This gave planners a common resource for comparing areas without first commissioning a separate study of every basin. The example illustrates how a national institution can make distributed research usable across jurisdictions, including by projects seeking storage for removals. Its estimates remain a starting point for site selection; they do not establish the availability or price of commercial storage.

US biomass supply assessment and open data

The US Department of Energy commissioned Oak Ridge National Laboratory, a federal research laboratory, to assess renewable carbon resources in the 2023 Billion-Ton Report, published in 2024. The assessment describes quantities, prices, geographic distribution and market maturity under stated economic and environmental constraints. Agricultural-residue estimates retain material for soil conservation, while forestry estimates exclude sensitive areas and limit harvest relative to growth. The accompanying data portal makes the underlying resource information accessible and records later corrections. These features let developers compare plausible supply conditions instead of treating all biomass as available feedstock. For biochar or biomass-based removals, the transferable mechanism is public assessment of the materials a project could obtain. The report is a biomass-resource assessment, not a finding that those resources are committed to CDR or that using them will necessarily produce net removals.
