1. Introduction

Electricity-related climate policies occupy a central position in modern energy law because electricity generation and consumption are closely connected with greenhouse-gas emissions, renewable-energy deployment, energy efficiency, grid development, coal and gas use, and the achievement of net-zero targets. Governments therefore increasingly adopt policies concerning renewable-energy obligations, coal phase-outs, emissions standards, electricity-market design, carbon pricing, transmission infrastructure, energy efficiency, and support for clean technologies.

Judicial review provides a legal mechanism through which courts examine whether governmental and regulatory decisions concerning these policies have been made lawfully. The court generally does not substitute its own preferred energy or climate policy for that of the elected government. Instead, it examines questions such as:

whether the authority acted within its statutory powers;

whether mandatory climate and environmental duties were considered;

whether relevant evidence was ignored;

whether the decision was irrational or unreasonable;

whether environmental-impact assessment requirements were satisfied;

whether fundamental or human rights were respected;

whether the decision-maker properly considered climate targets and emissions consequences; and

whether the decision-making process was procedurally fair.

The importance of judicial review has increased as climate policy has moved from broad political commitments into legally enforceable statutory and regulatory frameworks.

2. Meaning of Electricity-Related Climate Policies

Electricity-related climate policies include measures affecting the production, transmission, distribution, and consumption of electricity for climate-mitigation purposes.

They may include:

Renewable-energy policies – solar, wind, hydro and other renewable generation.

Coal and fossil-fuel phase-out policies.

Carbon-emission standards for power stations.

Renewable purchase or clean-energy obligations.

Green open-access rules.

Electricity-market reforms designed to encourage low-carbon generation.

Energy-efficiency requirements.

Grid-modernisation and transmission policies supporting renewable integration.

Electricity-storage regulation.

Climate-related planning and environmental approvals for power projects.

Carbon pricing and emissions-trading mechanisms.

Government subsidies and financial support for renewable electricity.

Judicial review may arise where a government department, electricity regulator, planning authority or other public body adopts, implements or refuses to implement such measures.

3. Grounds of Judicial Review

A. Illegality

The first question is whether the public authority had lawful power to make the decision.

An electricity regulator cannot, for example, impose a climate-related requirement that falls outside the authority granted to it by electricity legislation.

The relevant statute may, however, give regulators broad responsibilities concerning:

environmental protection;

sustainable development;

consumer interests;

security of supply;

economic efficiency; and

emissions reduction.

Where Parliament has imposed climate-related statutory duties, failure to comply with them may make an electricity policy unlawful.

B. Failure to Consider Relevant Climate Factors

A particularly important issue is whether the decision-maker considered matters that legislation requires it to consider.

For example, when approving a major electricity infrastructure project, the authority may be required to consider:

greenhouse-gas emissions;

environmental impacts;

climate targets;

cumulative environmental effects;

alternatives;

renewable-energy implications; and

long-term sustainability.

A court may intervene if a legally relevant climate consideration was completely ignored.

This does not mean that every climate consideration must automatically determine the outcome. The question is whether the decision-maker approached the statutory task lawfully.

4. Irrationality and Unreasonableness

A climate-related electricity decision can also be challenged on conventional administrative-law grounds.

The claimant may argue that the decision was irrational because the authority:

relied upon demonstrably incorrect information;

ignored critical evidence;

made an internally contradictory decision;

relied on an assumption that had no reasonable evidential basis; or

failed to address an obvious risk relevant to its statutory duty.

Climate cases are particularly significant because electricity policy frequently depends on complex modelling.

Governments may use projections concerning:

future electricity demand;

renewable generation;

grid capacity;

electricity prices;

emissions;

technology costs; and

future energy consumption.

Courts generally recognise the technical nature of these questions, but technical complexity does not immunise decisions from judicial review.

5. Judicial Deference to Technical Energy Authorities

Electricity regulation frequently involves specialised institutions.

Courts may therefore show substantial respect for the expertise of:

electricity regulators;

energy ministries;

system operators;

environmental agencies; and

planning authorities.

However, deference is not immunity.

The distinction is important:

Courts ordinarily do not decide which electricity policy is economically or technologically optimal, but they can determine whether the authority reached its decision through a legally permissible process.

This distinction is particularly important where climate policy involves competing considerations such as:

affordability versus decarbonisation;

energy security versus fossil-fuel reduction;

renewable expansion versus biodiversity protection;

grid reliability versus rapid infrastructure transformation.

6. United Kingdom: Friends of the Earth v Secretary of State for BEIS

R (Friends of the Earth Ltd and Others) v Secretary of State for Business, Energy and Industrial Strategy

[2022] EWHC 1841 (Admin)

This is one of the most important judicial-review decisions concerning government climate policy.

The claim challenged the UK's Net Zero Strategy under the Climate Change Act 2008. The legislation required the Secretary of State to prepare policies and proposals capable of enabling legally binding carbon budgets to be met.

The High Court found important deficiencies in the Government's approach.

The court held, in substance, that the Secretary of State had not been properly informed about the quantified emissions reductions expected from individual policies and had therefore failed to discharge the statutory duty properly. The court also identified deficiencies in the information supplied concerning the risks associated with achieving the carbon budgets. (Bailii)

Importance for electricity law

The case demonstrates that climate policies are reviewable when Parliament has converted climate objectives into statutory duties.

This has direct implications for electricity policy because the power sector is one of the principal sectors through which carbon budgets must be achieved.

A government cannot necessarily say:

"Climate policy is a political question, therefore courts cannot examine it."

Where legislation imposes a specific duty, the court can examine whether that duty has been properly performed.

7. Friends of the Earth v Secretary of State for Energy Security and Net Zero (2024)

The subsequent challenge concerned the Government's Carbon Budget Delivery Plan.

The High Court again examined whether the Secretary of State had properly complied with the Climate Change Act 2008.

The court held that the Secretary of State had acted unlawfully in part because the decision-making process proceeded on an assumption that the government's proposals and policies would be delivered in full, despite the evidential position concerning delivery risks. The case illustrates the importance of evidence and realistic implementation assumptions in climate policymaking. (Courts and Tribunals Judiciary)

Significance

For electricity policy, this is particularly relevant to policies involving:

renewable-energy deployment;

electricity-grid expansion;

energy-efficiency programmes;

clean-power targets;

carbon capture;

electricity storage; and

fossil-fuel retirement.

A policy document may appear ambitious on paper, but judicial review can examine whether the underlying assumptions provide a lawful basis for concluding that statutory climate targets can actually be achieved.

8. Finch v Surrey County Council

R (Finch on behalf of the Weald Action Group) v Surrey County Council

[2024] UKSC 20

This is a major climate-related judicial-review decision.

The case concerned permission for oil extraction in Surrey. The central question was whether the environmental impact assessment had to consider the greenhouse-gas emissions produced when the extracted oil was eventually burned.

The UK Supreme Court, by a 3–2 majority, held that the downstream combustion emissions were within the scope of the environmental impact assessment required by law. (Supreme Court UK)

The Court emphasised that the purpose of environmental impact assessment is to ensure that environmental effects are exposed to public discussion and considered before consent is granted.

Relevance to electricity

Although Finch concerned oil extraction rather than an electricity-generating facility, its reasoning is highly relevant to electricity infrastructure.

For example, where an authority considers:

a new gas-fired power station;

a coal-fired power project;

a major fossil-fuel supply infrastructure project;

a transmission project facilitating fossil generation; or

an integrated energy project,

the question may arise whether consequential greenhouse-gas emissions are legally relevant.

The case demonstrates that climate consequences cannot always be treated as too remote merely because they occur downstream.

9. Climate Impact Assessment and Electricity Projects

Finch strengthens the importance of environmental-impact assessment in energy law.

Consider a hypothetical gas-fired power station.

The authority might assess:

emissions from construction;

emissions from operation;

local air pollution;

water consumption;

land use.

A climate challenge may additionally ask whether the authority properly considered the project's broader greenhouse-gas consequences.

The precise legal answer depends upon the governing legislation and the causal relationship between the project and emissions. But Finch demonstrates that courts can scrutinise a narrow interpretation of environmental effects.

10. India: M.K. Ranjitsinh v Union of India

M.K. Ranjitsinh v Union of India

2024 INSC 280

This is particularly important for Indian electricity and climate law.

The Supreme Court considered the relationship between protection of the Great Indian Bustard, electricity transmission infrastructure and India's renewable-energy transition.

The Court recognised a constitutional right against the adverse effects of climate change, deriving it principally from Articles 14 and 21. The judgment also discussed India's renewable-energy policies and noted the importance of transitioning towards non-fossil-fuel sources. (Indian Kanoon)

The judgment specifically recognised that India's legal and policy framework includes the Energy Conservation Act 2001, the Electricity (Promoting Renewable Energy Through Green Energy Open Access) Rules 2022 and various renewable-energy programmes. (Indian Kanoon)

Why the case matters

The case illustrates an important feature of judicial review of electricity climate policy:

Climate protection and biodiversity protection may themselves conflict.

Renewable-energy projects require:

transmission lines;

substations;

solar installations;

wind infrastructure;

storage facilities.

At the same time, those projects may affect wildlife habitats.

The Court therefore had to balance environmental protection with the need for renewable-energy infrastructure.

This demonstrates that judicial review does not necessarily mean courts will always favour renewable development. Instead, courts can require public authorities to reconcile competing constitutional and environmental interests through lawful decision-making.

11. Constitutional Dimension in India

M.K. Ranjitsinh is significant because it moves climate considerations beyond ordinary environmental policy.

The Court explained that Articles 14 and 21 provide constitutional foundations for protection against adverse climate effects. (Indian Kanoon)

This potentially gives courts a stronger basis for reviewing electricity policies that have substantial climate consequences.

For example, future challenges could potentially concern:

discriminatory access to clean electricity;

arbitrary withdrawal of renewable-energy incentives;

policies producing serious environmental harm;

failure to consider climate vulnerability;

disproportionate effects of electricity policies on vulnerable communities.

The precise scope of this constitutional right will develop through subsequent litigation.

12. European Court of Human Rights: KlimaSeniorinnen

Verein KlimaSeniorinnen Schweiz and Others v Switzerland

Application No. 53600/20, Grand Chamber, 9 April 2024

The European Court of Human Rights held that the European Convention encompasses protection against serious adverse effects of climate change.

The Court found a violation of Article 8 in relation to Switzerland's failure to comply with its positive obligations concerning climate change and also found an Article 6 violation concerning access to court for the association. (HUDOC)

Electricity-policy significance

The judgment is relevant to electricity policy because electricity decarbonisation is a major component of national climate mitigation.

It strengthens the argument that climate policy is not merely an optional political objective where human-rights obligations require effective protection against climate harms.

Nevertheless, the judgment does not mean that courts must design electricity policy themselves. The institutional question remains one of judicial supervision rather than judicial administration.

13. Urgenda Foundation v Netherlands

Urgenda Foundation v State of the Netherlands

The Dutch litigation culminating in the Supreme Court's 2019 judgment is another major climate case.

The courts accepted that the Dutch State had positive obligations concerning climate protection under Articles 2 and 8 of the European Convention on Human Rights.

The case is important because it demonstrates how courts can review the adequacy of governmental climate action where human-rights obligations are engaged.

For electricity policy, the reasoning is relevant to government decisions concerning:

fossil-fuel dependence;

emissions reduction;

renewable electricity;

energy transition;

national climate targets.

Its significance lies less in prescribing a particular electricity technology and more in recognising that inadequate climate protection can, in appropriate circumstances, raise enforceable legal obligations.

14. Milieudefensie v Shell: Limits of Judicial Climate Intervention

Milieudefensie et al v Royal Dutch Shell

This litigation provides an important counterpoint.

In 2021, the District Court of The Hague ordered Shell to reduce its global CO₂ emissions by 45% by 2030 compared with 2019 levels. The case involved Scope 1, 2 and 3 emissions.

However, in November 2024 the Hague Court of Appeal overturned that judgment and dismissed the claim. Among other things, the appellate court concluded that it could not establish a specific reduction percentage for Shell's Scope 3 emissions and questioned the effectiveness of imposing such an order on an individual company. (Shell Nederland)

The case is currently subject to proceedings before the Supreme Court of the Netherlands; a hearing took place in May 2026. (Shell Nederland)

Importance

The case illustrates the boundary between:

judicial enforcement of legal obligations

and

judicial creation of detailed climate policy.

That distinction is especially important in electricity law, where courts may be asked to determine whether a government must:

close coal plants;

accelerate renewable procurement;

impose particular emissions limits;

alter electricity-market rules; or

change its energy mix.

Courts must determine whether such relief is grounded in existing legal duties.

15. Judicial Review of Renewable-Energy Policies

Renewable-energy policies may be challenged from different directions.

Challenges by renewable developers

Developers may challenge:

withdrawal of subsidies;

discriminatory grid-access rules;

renewable auctions;

licensing decisions;

curtailment;

transmission restrictions;

changes to feed-in tariffs.

Challenges by environmental groups

Environmental organisations may challenge:

inadequate environmental assessment;

wildlife impacts;

insufficient climate assessment;

inadequate cumulative-impact assessment.

Challenges by consumers or competitors

They may challenge:

discriminatory tariffs;

preferential treatment;

unlawful subsidies;

regulatory decisions lacking statutory authority.

Thus, climate judicial review is not inherently pro-renewable or anti-renewable. Its legal function is to test lawfulness.

16. Judicial Review of Coal and Fossil-Fuel Electricity Policies

Fossil-fuel electricity policies may be challenged where authorities fail to account properly for:

greenhouse-gas emissions;

statutory climate targets;

environmental impacts;

air pollution;

climate-related financial risks;

alternatives;

cumulative emissions.

The reasoning in Finch is particularly relevant where environmental legislation requires assessment of climate effects. (Supreme Court UK)

Similarly, the UK Net Zero Strategy cases demonstrate that where climate legislation imposes a statutory duty, governmental assumptions about whether emissions targets can be met can become subject to judicial scrutiny. (Bailii)

17. Electricity Regulators and Climate Policy

Electricity regulators increasingly confront climate considerations in decisions concerning:

network investment;

electricity tariffs;

connection queues;

renewable integration;

market rules;

storage;

demand response;

consumer protection;

system reliability.

Judicial review may examine whether regulators have properly exercised their statutory powers.

Suppose an electricity regulator has a statutory duty to promote sustainable development.

If it adopts a regulatory framework that completely ignores a legally relevant climate objective, a claimant could potentially argue:

(1) the regulator misunderstood its statutory mandate;

(2) relevant considerations were ignored;

(3) the decision was irrational; or

(4) the regulator failed to provide adequate reasons.

However, courts are generally unlikely simply to replace the regulator's technical assessment with their own preferred economic model.

18. Climate Policy, Energy Security and Affordability

One of the most difficult issues is the relationship between climate mitigation and electricity security.

A government may justify continued gas or coal generation on the basis of:

electricity reliability;

grid stability;

energy security;

affordability;

geopolitical risks.

A climate claimant may argue that these considerations are being used to avoid statutory climate obligations.

Judicial review requires the court to determine whether the authority:

identified the correct statutory objectives;

considered relevant evidence;

properly balanced competing statutory factors;

gave rational reasons; and

acted within the discretion Parliament provided.

The court ordinarily does not decide the country's entire electricity mix.

19. Proportionality and Human Rights

Where climate and electricity policies affect fundamental rights, proportionality may become important.

A court may ask whether:

the policy pursues a legitimate objective;

it is rationally connected to that objective;

a less restrictive alternative was reasonably available; and

the overall balance between competing interests is justified.

This can become particularly significant where electricity policies affect:

health;

housing;

energy access;

vulnerable communities;

indigenous or local communities;

property rights.

The European climate cases demonstrate how climate protection can intersect with human-rights law. (HUDOC)

20. Procedural Fairness

Climate-related electricity decisions may also be challenged for procedural defects.

Examples include:

inadequate public consultation;

failure to disclose important modelling;

failure to provide legally required reasons;

failure to consider objections;

failure to consult statutory environmental bodies.

Procedural fairness is particularly important for large infrastructure projects because decisions can affect:

landowners;

electricity consumers;

local communities;

renewable developers;

fossil-fuel companies;

environmental organisations.

21. Role of Scientific Evidence

Climate litigation is heavily evidence-based.

Courts may encounter:

emissions models;

climate projections;

electricity-demand forecasts;

renewable-generation scenarios;

grid-stability studies;

biodiversity assessments;

cost-benefit analysis.

The court does not normally become a scientific policymaker.

Instead, it asks whether the decision-maker:

had a lawful and rational evidential basis for the conclusion reached.

This principle is clearly illustrated by the UK Net Zero Strategy litigation, where the problem was not simply disagreement over climate policy but the adequacy of the information and assumptions underlying the government's statutory decision. (Bailii)

22. Separation of Powers

Climate litigation inevitably raises separation-of-powers questions.

Legislature

Parliament creates the statutory framework.

Executive

Government determines detailed energy and climate policy.

Regulators

Specialised authorities implement legislation and regulate electricity markets.

Judiciary

Courts determine whether these institutions have acted lawfully.

The most sustainable approach to judicial review is therefore generally:

review legality without assuming the policymaking function.

This distinction explains why courts may invalidate a climate policy-making process while leaving the government substantial discretion concerning what policy should replace it.

23. Comparative Case-Law Principles

24. Key Principles Emerging from the Case Law

Several principles can be identified.

1. Climate policy is increasingly justiciable

Climate change is no longer treated universally as an exclusively political subject.

Where legislation or constitutional/human-rights norms impose legal obligations, courts can review governmental action.

2. Statutory duties are crucial

The strongest judicial-review claims generally arise where climate objectives have been incorporated into legislation.

The UK Climate Change Act litigation is a strong example. (Bailii)

3. Courts scrutinise reasoning rather than simply policy outcomes

A court may ask whether the authority:

considered the right factors;

relied upon reliable information;

understood its legal duties; and

provided rational reasons.

4. Environmental assessment has become increasingly important

Finch demonstrates the significance of identifying climate consequences at the environmental-assessment stage. (Supreme Court UK)

5. Climate and biodiversity interests must sometimes be balanced

M.K. Ranjitsinh illustrates the complexity of simultaneously protecting biodiversity and developing renewable electricity infrastructure. (Indian Kanoon)

6. Courts have institutional limits

Even where climate change creates serious legal concerns, courts generally have to identify a legal basis for the remedy they grant.

The Shell litigation demonstrates the difficulty of translating broad climate objectives into a precise court-imposed emissions obligation. (Shell Nederland)

25. Application to Electricity Law

The developing jurisprudence has several practical consequences for electricity regulators and governments.

Before adopting a major electricity climate policy, authorities should ideally:

identify all relevant statutory duties;

identify applicable climate targets;

assess greenhouse-gas consequences;

consider energy-security implications;

examine affordability and consumer impacts;

assess biodiversity and environmental effects;

use reliable scientific and economic evidence;

assess implementation risks;

conduct legally required consultation;

provide adequate reasons;

explain how competing objectives have been balanced; and

maintain an evidential record capable of defending the decision under judicial review.

This is particularly important for long-term electricity policies because decisions about power plants and transmission networks can create carbon lock-in for decades.

26. Conclusion

Judicial review of electricity-related climate policies represents the intersection of administrative law, energy law, environmental law, constitutional law and climate law.

The modern case law does not establish that judges should determine the national electricity mix. Instead, it establishes that climate considerations can become legally enforceable when incorporated into statutory duties, environmental-assessment requirements or constitutional and human-rights protections.

The UK cases such as Friends of the Earth demonstrate that governments must comply carefully with statutory climate-planning duties. (Bailii) Finch demonstrates that courts may require decision-makers to confront significant climate consequences within environmental assessment. (Supreme Court UK) In India, M.K. Ranjitsinh significantly strengthens the constitutional dimension by recognising protection against the adverse effects of climate change under Articles 14 and 21 while also illustrating the need to reconcile climate mitigation with biodiversity protection. (Indian Kanoon)

The emerging principle can therefore be stated as follows:

Electricity climate policy remains primarily a function of legislatures, governments and specialised regulators, but the exercise of that function is subject to legal constraints concerning statutory duties, environmental assessment, rationality, procedural fairness and fundamental rights.

Judicial review consequently acts not as a substitute for electricity policymaking, but as a legal accountability mechanism for the climate consequences of public energy decisions.
