1. Introduction 

Carbon Capture Biotechnology Law is an emerging interdisciplinary area of environmental, energy, biotechnology, corporate and climate law that governs technologies used to capture carbon dioxide (CO₂), convert it into useful products, store it safely, and potentially remove carbon from the atmosphere using biological systems.

It is not yet a universally recognized, standalone legal doctrine. Instead, it combines established environmental laws, emerging carbon-management regulations, biotechnology rules, intellectual property rights and climate-policy frameworks.

In India, the NITI Aayog report Carbon Capture, Utilization, and Storage (CCUS) Policy Framework and its Deployment Mechanism in India (November 2022) examines capture technologies, biological and industrial utilization pathways, geological storage and potential deployment mechanisms.

3. Industrial carbon capture and utilization

Chemical processes separate CO₂ from industrial emissions. The gas may then be converted into chemicals, mineral products or fuels. The principal legal issues include permits, emissions accounting, occupational safety and product claims.

4. Carbon capture and geological storage (CCS)

Captured CO₂ is compressed, transported and injected into suitable underground formations. The central legal issues are site approval, groundwater protection, leakage, monitoring, financial assurance and long-term responsibility.

An essential legal distinction is that capturing carbon is not necessarily the same as permanently removing it from the atmosphere. Carbon converted into a short-lived fuel or product may return to the atmosphere, whereas verified durable storage can prevent its release over much longer periods.

2. Legal foundations and regulatory framework in India

India does not yet have a single comprehensive statute governing every aspect of carbon capture, utilization and storage. Projects must therefore be assessed under the applicable existing laws, sector-specific regulations and any newer rules governing particular activities.

The following framework is particularly relevant.

The precise permissions depend on the project's location, scale, technology and environmental effects. Not every carbon-capture facility automatically requires every listed approval.

A significant development is that the 2025 amendment to the Oilfields (Regulation and Development) Act expanded the legal framework relevant to decarbonization and carbon storage in oilfields. Nevertheless, this does not amount to a complete, generally applicable CCUS code for every biological and industrial process.

Constitutional dimensions

Three constitutional provisions are particularly important:

Article 21: The Supreme Court has interpreted the right to life to include protection against serious environmental harm.

Article 48A: Directs the State to protect and improve the environment.

Article 51A(g): Establishes the citizen's fundamental duty to protect and improve the natural environment.

These provisions help courts evaluate environmental decisions, regulatory failures and the balance between technological development and ecological protection.

3. Leading case laws and their legal principles

There is no established body of reported judgments specifically defining a comprehensive doctrine called Carbon Capture Biotechnology Law. However, Indian environmental judgments provide important rules for assessing liability, while overseas carbon-storage enforcement illustrates the practical application of permit and monitoring obligations.

A. Indian Supreme Court cases

1. M.C. Mehta v. Union of India (1987) 1 SCC 395

Oleum Gas Leak Case · Absolute liability

Facts and principle: Following a hazardous oleum gas leak from an industrial enterprise in Delhi, the Supreme Court developed the doctrine of absolute liability for enterprises engaged in hazardous or inherently dangerous activities.

Application to carbon capture biotechnology: If a carbon-capture plant, chemical facility or associated hazardous operation causes injury through a dangerous leak or industrial accident, this doctrine may be relevant. Its application depends on the nature of the activity, the harm and the legal circumstances.

Legal significance: Compliance with safety procedures does not automatically eliminate liability under the Indian absolute-liability doctrine.

2. Indian Council for Enviro-Legal Action v. Union of India (1996) 3 SCC 212

Polluter-pays principle · Remediation costs

Facts and principle: Industrial chemical pollution in Rajasthan caused serious environmental damage. The Court required the polluting industries to bear the costs associated with remedying the pollution.

Application: If a carbon-capture facility contaminates groundwater, improperly disposes of chemical waste or damages land through leakage, regulators and affected parties may seek remediation and compensation under applicable law.

Legal significance: A polluter should not shift the environmental cleanup burden to the public merely because its operations serve an economic or climate-related objective.

3. Vellore Citizens' Welfare Forum v. Union of India (1996) 5 SCC 647

Precautionary principle · Sustainable development

Facts and principle: The case concerned pollution caused by tanneries in Tamil Nadu. The Court recognized the precautionary principle and the polluter-pays principle as essential features of Indian environmental law.

Application: Authorities may require risk assessment, appropriate monitoring and preventive safeguards before permitting biological carbon-capture processes or underground CO₂ storage where significant environmental risks are involved.

Legal significance: Scientific uncertainty is not necessarily a justification for ignoring credible risks of serious environmental harm.

4. M.C. Mehta v. Kamal Nath (1997) 1 SCC 388

Public trust doctrine · Protection of natural resources

Principle: The Court applied the public trust doctrine to the protection of natural resources, including rivers and ecologically important areas.

Application: Carbon-storage projects should not be treated as automatically permissible when they threaten groundwater, rivers, wetlands or other resources held for public benefit.

Legal significance: Private investment and technological development must remain consistent with the State's environmental responsibilities.

5. Hindustan Zinc Ltd. v. Rajasthan Electricity Regulatory Commission (2015) 12 SCC 611

Environmental obligations · Regulatory authority

Principle: The Supreme Court upheld the regulatory approach requiring generating companies to comply with renewable-energy obligations under the applicable electricity-law framework.

Application: The decision can support the broader proposition that statutory regulators may enforce environmental and energy-policy obligations within their legal powers.

Important limitation: It is not a judgment directly authorizing carbon capture, mandating CO₂ storage or establishing a standalone CCUS regulatory regime.

Illinois Industrial Carbon Capture and Sequestration Project

Facts: The U.S. Environmental Protection Agency identified violations relating to monitoring and the migration of injected fluids into an unauthorized underground zone at ADM's carbon-storage project in Decatur, Illinois.

In August 2025, the EPA issued a final order requiring compliance measures under the Safe Drinking Water Act and the project's Class VI permit.

US EPA+1

Legal significance: This is a regulatory enforcement example, not a court judgment. It demonstrates that climate benefits do not excuse non-compliance with injection permits, monitoring duties or emergency-response requirements.

Application to biotechnology: A project using fermentation or biofuel production to generate a concentrated CO₂ stream must still comply with the applicable rules governing transportation and storage if that CO₂ is injected underground.

7. U.S. EPA approval of Wabash Carbon Services injection wells (2024)

Underground Injection Control · Class VI permits

The EPA approved construction of two proposed CO₂ injection wells in Indiana in January 2024, subject to a separate approval before injection could begin. The permits followed technical review and public participation.

US EPA+1

Legal significance: Authorization to construct is not necessarily authorization to begin injection. Carbon-storage regimes can impose distinct approval stages and continuing oversight obligations.

Application: Developers should distinguish pilot-plant approval, industrial operating permission, transport authorization and geological injection permission rather than assuming one approval covers the entire project.

8. Illinois SAFE CCS Act, effective 2024

State statutory framework · Landowner safeguards

Illinois enacted a state-specific carbon sequestration law supplementing federal regulation. Its provisions address additional permitting requirements and, in specified circumstances involving significant CO₂ leaks, medical monitoring for affected landowners at the operator's expense.

Carbon Capture and Storage Law+1

Legal significance: This is legislation, not a judicial precedent. It illustrates how a jurisdiction can create additional local protections beyond a general underground-injection permit.

Application: It offers a comparative model for considering landowner notice, leak monitoring, emergency response, financial assurance and community protections in Indian CCUS legislation.

How to interpret these authorities: The first five are judicial decisions establishing general legal principles applicable by analogy. The later examples are regulatory or legislative developments directly concerned with carbon storage. None should be misrepresented as a judgment expressly establishing a universal doctrine of carbon capture biotechnology law.

4. Legal issues specific to biological carbon capture

4.1 Biosafety and environmental release

Biological capture may involve algae, genetically modified microorganisms or engineered biological pathways.

The principal legal questions are:

Does the organism require authorization for laboratory use, contained research or environmental release?

Could it spread beyond the intended facility or affect native species?

Could its metabolites, waste products or interactions with local ecosystems create harm?

Who bears responsibility if the organism causes unexpected ecological damage?

In India, genetically engineered organisms may trigger the Environment (Protection) Act, 1986, and the 1989 Rules governing the manufacture, use, import, export and storage of hazardous microorganisms, genetically engineered organisms or cells, as applicable.

A contained bioreactor is legally and environmentally different from releasing engineered organisms into rivers, oceans or open land. Authorization for one setting does not automatically authorize the other.

4.2 Patents and ownership of biological inventions

Carbon-capture biotechnology may produce valuable inventions, including engineered enzymes, microorganisms, bioreactor configurations and improved conversion processes.

Under the Indian Patents Act, 1970, patentability depends on statutory requirements and exclusions. Section 3(j), for example, excludes plants and animals in whole or in part, other than microorganisms, as well as seeds, varieties and species and essentially biological processes for production or propagation of plants and animals.

This means that a microbial carbon-conversion invention must be evaluated on its actual technical features; it cannot be assumed that every biological invention is patentable.

Relevant questions include:

Who owns the engineered strain or enzyme?

Does a research institution retain rights under a collaboration agreement?

Are biological resources subject to applicable access and benefit-sharing requirements?

Does a licence permit commercial deployment, sublicensing and use in another jurisdiction?

Are trade secrets, process data and genetic sequence information adequately protected?

4.3 Biological resource access and benefit-sharing

Where a project uses biological resources obtained from India, the Biological Diversity Act, 2002, as amended, and applicable rules may be relevant.

The legal analysis should consider the identity of the resource, the nationality and legal status of the applicant, the intended research or commercial use, applicable exemptions, and the rules governing access and benefit sharing.

Not every use of an ordinary microorganism automatically attracts the same requirements. The statutory conditions and applicable exemptions must be examined in each case.

4.4 Carbon credits and measurement

A company cannot legitimately equate the amount of CO₂ captured with the amount of CO₂ permanently removed.

For a biological project, credible accounting should address:

The quantity of CO₂ captured.

The energy and materials consumed by the process.

Emissions from cultivation, transport, processing and waste treatment.

The fate of the biomass or converted product.

The duration and reliability of carbon storage.

Leakage, reversal risks and independent verification.

Where carbon credits are claimed, contractual representations and applicable crediting rules should specify who owns the environmental attributes, how double counting is prevented and what happens if storage later fails.

5. Liability and enforcement doctrines

Carbon capture biotechnology projects can expose developers, technology providers, plant operators, transporters and storage-site owners to different forms of liability.

Important legal doctrines

A. Polluter pays principle

The party responsible for pollution may be required to bear the costs of remediation and compensation. This principle is especially relevant when a project causes environmental damage despite claiming to serve climate objectives.

B. Precautionary principle

Where credible risks of serious environmental harm exist, preventive safeguards and adequate risk assessment may be required even when scientific certainty is incomplete.

C. Absolute liability

Under the Indian doctrine developed in M.C. Mehta v. Union of India (Oleum Gas Leak Case), enterprises conducting hazardous or inherently dangerous activities can be subject to stringent liability for resulting harm.

D. Public trust doctrine

Natural resources cannot simply be treated as unrestricted commercial assets. Government decisions affecting rivers, groundwater, forests and other public resources remain subject to environmental duties.

These doctrines are not automatic substitutes for every statutory requirement. Their application depends on the facts, the nature of the activity, the injury and the relevant legal proceedings.

6. International legal framework

Carbon capture biotechnology projects operating across national borders may need to comply with international climate, biodiversity and marine-protection obligations, as implemented through applicable domestic law.

Paris Agreement: Provides the international framework for national climate action. Article 6 mechanisms also make the integrity of emissions accounting and avoidance of double counting important.

Convention on Biological Diversity: Relevant to biodiversity conservation and the sustainable use of biological resources, subject to the treaty's scope and domestic implementation.

Cartagena Protocol on Biosafety: Relevant to specified transboundary movements of living modified organisms resulting from modern biotechnology.

London Protocol: Relevant to the dumping of wastes and other matter at sea, including certain CO₂ streams intended for geological sub-seabed storage.

UNCLOS: May be relevant to marine environmental protection and offshore activities.

The precise obligations vary with the technology, the location of the project, the substances involved and the applicable treaty provisions. International commitments do not necessarily create a directly enforceable private claim in domestic courts without the required legal basis.

7. India's emerging CCUS policy and regulatory direction

India's 2022 NITI Aayog report provides an important policy foundation for carbon capture, utilization and storage, including biological and industrial utilization options. However, a policy report should not be confused with a binding, comprehensive statute.

The legal direction for future regulation should include:

Dedicated project approvals: Clear rules for capture facilities, pipelines, injection wells and biological systems.

Biosafety safeguards: Appropriate containment, testing, environmental-release and monitoring requirements.

Storage-site regulation: Geological suitability assessments, groundwater protection and continuing monitoring.

Long-term liability: Defined responsibilities for leakage, abandoned wells, site closure and post-closure monitoring.

Financial assurance: Insurance, bonds or other appropriate mechanisms to fund remediation and compensation.

Transparent carbon accounting: Standardized measurement, reporting, verification and reversal procedures.

Community participation: Disclosure of risks, public consultation where required, grievance mechanisms and emergency planning.

Research and commercialization rules: Clear provisions for patents, biological resources, data ownership and benefit sharing.

The OECD's Legal and Regulatory Frameworks for CCUS handbook provides a useful comparative resource for evaluating permitting, monitoring, liability and institutional design.

8. Illustrative legal problem

Suppose an Indian biotechnology company engineers microalgae to capture CO₂ from a cement plant. The company processes the resulting biomass into a commercial product and sends the remaining concentrated CO₂ to an underground storage operator.

Three separate legal inquiries arise.

Stage 1: Biological capture

Determine whether the strain requires biosafety authorization, whether wastewater and emissions are adequately controlled, and whether any biological-resource access obligations apply.

Stage 2: Biomass conversion

Establish product safety, process-waste compliance, patent ownership, commercial licences and accurate carbon-accounting boundaries.

Stage 3: Geological storage

Verify the required project approvals, storage-site suitability, injection monitoring, emergency plans and contractual allocation of long-term liability.

If the underground operator subsequently causes groundwater contamination, the operator's contractual obligations and statutory duties must be examined alongside applicable environmental-liability principles. The biotechnology company may also face liability if its own negligence, contractual undertaking or other legally relevant conduct contributed to the harm.

The fact that the overall project reduces emissions would not, by itself, provide immunity from liability.

9. Conclusion

Carbon Capture Biotechnology Law is best understood as a developing legal field at the intersection of environmental protection, biotechnology regulation, climate governance, intellectual property and carbon-accounting integrity.

The most important Indian precedents for its general legal principles are:

M.C. Mehta v. Union of India (1987) — absolute liability.

Indian Council for Enviro-Legal Action v. Union of India (1996) — polluter pays and remediation.

Vellore Citizens' Welfare Forum v. Union of India (1996) — precautionary principle and sustainable development.

M.C. Mehta v. Kamal Nath (1997) — public trust doctrine.

Hindustan Zinc Ltd. v. Rajasthan Electricity Regulatory Commission (2015) — regulatory authority within the applicable energy-law framework.

Together, these decisions provide a substantial foundation for evaluating environmental risks and accountability in carbon capture projects. They do not, however, replace the need for specific statutory rules governing biological capture, CO₂ transportation, geological storage, carbon-credit verification and long-term liability.

For a more advanced legal study, the most useful next step would be a comparative case-law analysis of India, the United States, the United Kingdom and the European Union, focusing specifically on carbon-storage leakage, biotechnology biosafety, liability allocation and regulatory gaps.
