Why in the News?

An opinion article argues that Delhi’s EV Policy 2.0 and India’s air pollution efforts require long-term political will and focus on major pollution sources for effective air quality improvement.

News in Brief

• Delhi plans to ban registration of new petrol, diesel and CNG three-wheelers/LGVs from 2027 and allow only electric two-wheelers from 2028 to reduce emissions at the source.
• The article notes that heavy commercial vehicles and buses remain the biggest transport polluters, making EV measures alone insufficient.
• Effective air pollution control requires long-term, science-based policymaking and consistent implementation beyond election cycles.

Key Issues Highlighted

Gap Between Science and Policy

• Scientific studies have consistently identified the major sources of air pollution and recommended targeted interventions.
• However, environmental policies often change with changes in governments or electoral priorities, resulting in inconsistent implementation.
• Air pollution is a long-term public health challenge that requires evidence-based policymaking, institutional continuity, and bipartisan political commitment rather than short-term electoral considerations.

Transport Sector Pollution

• According to the National Institute of Advanced Studies (NIAS), 2025, the transport sector contributes nearly 41% of Delhi’s PM2.5 emissions, making it the single largest source of urban air pollution.
• Heavy commercial vehicles and buses account for nearly 60% of transport-related emissions despite being fewer in number.
• The primary reason is the widespread use of diesel engines, which emit:
  • PM2.5 (fine particulate matter) that penetrates deep into the lungs,
  • Nitrogen Oxides (NOx) that contribute to smog and respiratory illnesses,
  • Black Carbon, a short-lived climate pollutant that accelerates global warming.
• Reducing emissions from these vehicles can therefore have a significant impact on improving urban air quality.

Electric Vehicle (EV) Transition

• Delhi’s revised EV Policy 2.0 proposes a phased transition towards electric mobility.
• Proposed Timeline
  • January 1, 2027: Ban on registration of new petrol, diesel and CNG three-wheelers and Light Goods Vehicles (LGVs).
  • April 1, 2028: Registration of only electric two-wheelers.
• Benefits
  • Reduces dependence on fossil fuels.
  • Lowers greenhouse gas and particulate emissions.
  • Improves urban air quality.
  • Reduces healthcare expenditure due to pollution-related diseases.
  • Lowers India’s oil import bill and strengthens energy security.
• The transition to EVs also supports India’s commitments under the Paris Agreement and the goal of achieving net-zero emissions by 2070.

Reasons to Target Heavy Vehicles

• Although heavy commercial vehicles, trucks, and buses constitute only a small proportion of the total vehicle fleet, they contribute a disproportionately large share of transport emissions because of:
  • Higher fuel consumption,
  • Greater annual distance travelled,
  • Predominant use of diesel engines.
• Electrifying these vehicles offers the highest pollution reduction per vehicle replaced, making it a more efficient strategy than focusing only on private cars or two-wheelers.

Public Health Benefits

• Air pollution is a major risk factor for non-communicable diseases. Cleaner air can significantly reduce the incidence of:
  • Asthma,
  • Chronic Obstructive Pulmonary Disease (COPD),
  • Lung cancer,
  • Stroke,
  • Cardiovascular diseases,
  • Premature mortality.
• Widespread adoption of electric vehicles could prevent around 800 premature deaths annually and save thousands of Disability Adjusted Life Years (DALYs) by reducing exposure to harmful pollutants.

Economic Benefits

• Reducing air pollution generates substantial economic gains by:
  • Lowering healthcare and treatment costs,
  • Reducing hospital admissions,
  • Improving labour productivity through better worker health,
  • Increasing economic output by reducing absenteeism,
  • Enhancing overall quality of life.
• Thus, investment in clean mobility and pollution control should be viewed as an investment in long-term economic growth rather than merely an environmental expenditure.

Political Economy Challenge

• Implementing ambitious environmental reforms often faces several obstacles, including:
  • Short-term electoral considerations,
  • Resistance from affected industries,
  • Fiscal constraints,
  • Frequent policy reversals with changes in government.
• To achieve sustained improvements in air quality, India requires:
  • Strong and stable environmental institutions,
  • Long-term financial support,
  • Political consensus across governments,
  • Consistent implementation of environmental regulations.
• Without policy continuity, the benefits of pollution-control measures remain limited.

Need to Phase Out CNG

• Compressed Natural Gas (CNG) is cleaner than diesel and petrol but is not a zero-emission fuel.
• It continues to emit:
  • Nitrogen Oxides (NOx), which contribute to urban air pollution,
    Carbon dioxide (CO₂), a major greenhouse gas.
• Therefore, while CNG can serve as a transitional fuel, the long-term objective should be to shift towards Zero Emission Vehicles (ZEVs) powered by electricity or green hydrogen, supported by renewable energy and robust charging infrastructure.
• This transition is essential for achieving cleaner air and India’s climate goals.

Way Forward

• Prioritise electrification of heavy commercial vehicles and public buses, as they contribute the highest transport emissions.
• Expand EV charging infrastructure across urban and rural areas to support large-scale adoption.
• Strengthen public transport to reduce dependence on private vehicles.
• Ensure policy continuity through long-term implementation beyond electoral cycles.
• Promote renewable energy to power EVs and maximise environmental benefits.
• Enforce stricter emission norms for diesel vehicles and phase out highly polluting fleets.
• Improve urban planning by encouraging compact cities, walking, and cycling infrastructure.
• Strengthen air quality monitoring and enforcement through better data, compliance, and regulatory action.

Birthright Citizenship Explained: U.S. Verdict, India’s Citizenship & Indian Diaspora

Source: Indian Diaspora
GS II: Indian Constitution, Indian Diaspora

Overview

1. News in Brief
2. Constitutional Basis of Birthright Citizenship in the U.S.
3. Impact on the Indian Diaspora
4. India’s Citizenship Framework
5. Way Forward

Why in the News?

The U.S. Supreme Court upheld birthright citizenship under the 14th Amendment, blocking attempts to deny automatic citizenship to children born in the U.S. to undocumented or temporary immigrants.

News in Brief

• The U.S. Supreme Court upheld birthright citizenship under the 14th Amendment, ensuring that children born in the U.S. (except those of foreign diplomats) remain eligible for automatic citizenship.
• The ruling reinforces constitutional protections and is a setback to efforts aimed at tightening U.S. immigration and citizenship policies.
• While the verdict benefits the Indian diaspora, concerns remain over H-1B visa restrictions, rising visa costs, and employment uncertainty for Indian professionals.

Constitutional Basis of Birthright Citizenship in the U.S.

• Birthright citizenship in the United States is guaranteed by the 14th Amendment (1868) to the U.S. Constitution. Its Citizenship Clause states:

“All persons born or naturalized in the United States, and subject to its jurisdiction, are citizens of the United States.”

• This provision was adopted after the American Civil War to ensure equal citizenship rights and has since been interpreted to grant automatic U.S. citizenship to almost every child born on U.S. soil, irrespective of the parents’ immigration status.
• Exception
  • Birthright citizenship does not apply to:
  • Children of foreign diplomats, as they are not subject to U.S. jurisdiction.

Challenge to Birthright Citizenship

• The Trump administration sought to restrict automatic citizenship for children born to undocumented immigrants and certain temporary visa holders.
• It argued that:
  • Birthright citizenship encourages illegal immigration.
  • It promotes “birth tourism”, where foreign nationals travel to the U.S. to give birth for citizenship benefits.
  • Existing laws are allegedly misused to obtain long-term immigration advantages.
  • The President should have the authority to restrict citizenship through executive action.

Supreme Court’s Stand

• The U.S. Supreme Court rejected attempts to restrict birthright citizenship and reaffirmed its constitutional protection because:
  • The 14th Amendment explicitly guarantees citizenship by birth.
  • An executive order cannot override the Constitution.
  • Any change requires a constitutional amendment, not executive action.
  • Long-standing judicial precedents have consistently upheld the Citizenship Clause.
  • The judgment reinforces the supremacy of the Constitution over executive decisions.

Difficulty in Amending the U.S. Constitution

• The U.S. Constitution has one of the most stringent amendment procedures in the world.
• A constitutional amendment requires:
  • Approval by a two-thirds majority in both the House of Representatives and the Senate.
    Ratification by three-fourths (38 out of 50) of the U.S. States.
  • Therefore, altering birthright citizenship through constitutional amendment is politically and legally difficult.

Impact on the Indian Diaspora

• Positive Impact
  • The judgment ensures that children born in the U.S. to Indian H-1B visa holders continue to receive automatic U.S. citizenship, providing legal certainty and stability to thousands of Indian families.
  • The ruling is particularly significant as Indians constitute the largest share of H-1B visa beneficiaries and form a major workforce in the U.S. IT, engineering, healthcare, and research sectors.
  • It also safeguards the citizenship rights of children born to Indian professionals during the lengthy employment-based Green Card waiting period, reducing uncertainty for the Indian diaspora.
• Challenges
  • Higher H-1B visa application and renewal costs.
  • Increased immigration scrutiny and compliance requirements.
  • Rising anti-immigrant sentiment in certain sections of society.
  • Employment uncertainty, particularly in the technology sector.
  • Long waiting periods for employment-based Green Cards due to country-wise caps.

India’s Citizenship Framework

• Unlike the United States, India does not follow unrestricted Jus Soli (citizenship by birth).
• The Citizenship Act, 1955 provides five modes of acquiring Indian citizenship:
  • By Birth (subject to statutory conditions)
  • By Descent
  • By Registration
  • By Naturalisation
  • By Incorporation of Territory
• The Citizenship (Amendment) Act, 2003 significantly tightened citizenship by birth provisions.
  • A child born in India does not automatically become an Indian citizen merely by birth.
  • At least one parent must be an Indian citizen, and the other parent must not be an illegal migrant.
• This reflects India’s shift from a broad Jus Soli approach towards a conditional citizenship-by-birth system, with greater emphasis on national security and regulation of illegal migration.

Way Forward

• Strengthen India–U.S. mobility partnership.
• Expose support the Indian diaspora.
• Create high-quality jobs in India to reduce excessive dependence on overseas employment opportunities.
• Encourage greater investment, technology transfer, knowledge sharing, and academic collaboration by the Indian diaspora for national development.
• Modernize India’s migration policy by developing a comprehensive migration framework that protects the rights of Indian migrants, facilitates safe and legal migration, and strengthens global talent mobility.

UPSC Prelims and Mains Practice Question

Consider the following statements regarding Birthright Citizenship:

1. Birthright citizenship is based on the principle of Jus Soli.
2. The U.S. Constitution grants automatic citizenship to every child born in the United States, including children of foreign diplomats.
