UGC NET Questions (Paper – 1)

The polluter pays principle states that the cost of pollution control and remediation should be borne by the polluter. It internalises environmental costs that would otherwise be external to the market. This principle provides an economic incentive for firms and individuals to reduce pollution. Therefore the description in the question clearly refers to the polluter pays principle.

Option A:
The precautionary principle advocates taking preventive action in the face of uncertainty to avoid serious or irreversible damage. It does not specifically assign costs to the polluter. Thus it does not match the definition given.

Option B:
Equity relates to fairness in the distribution of benefits and burdens among different groups. While polluter pays may promote a kind of equity,it is a more general value and not the specific policy rule defined in the question. Therefore it is not the most precise answer.

Option C:
The polluter pays principle directly links responsibility for pollution with financial liability. By making polluters responsible for the full environmental costs,it encourages cleaner technologies and processes. This is exactly the logic captured by the stem.

Option D:
Subsidiarity is a governance principle that decisions should be taken at the lowest appropriate level. It concerns allocation of authority rather than allocation of environmental costs. Hence it is not relevant to the concept described in the question.

The NGT is a specialised judicial body established to handle environmental disputes quickly and with technical expertise. It adjudicates civil cases involving substantial questions relating to the environment, including enforcement of legal rights, compensation and restoration. Its core role is to decide such cases, not to legislate or directly manage resources.

Option A:
Option A is incorrect because making laws is the function of Parliament and state legislatures; the NGT applies existing environmental laws rather than enacting new ones.

Option B:
Option B is correct since the NGT’s mandate is to hear and dispose of environmental cases concerning pollution, forests, biodiversity and other natural resources.

Option C:
Option C is incorrect as day-to-day management of parks and sanctuaries is handled by forest and wildlife departments, not by the NGT.

Option D:
Option D is incorrect because tax collection is carried out by revenue authorities; the NGT may impose penalties or compensation, but it is not a tax-collecting agency.

Human development focuses on expanding people’s freedoms and capabilities in areas such as health, education and participation. Environmental sustainability emphasises maintaining the integrity of ecosystems and resource bases. A coherent development strategy must bring these two together so that improvements in human well-being do not undermine the natural systems on which that well-being ultimately depends. The statement in Option B therefore captures the essential link between the two.

Option A:
Option A is incorrect since it treats technology as a guaranteed solution to all ecological problems and implies that environmental limits can be ignored. This view is risky and not supported by sustainability thinking, which stresses precaution and limits.

Option B:
Option B is correct because it recognises that human and environmental goals are interdependent. It aligns with the idea that development should be both people-centred and ecologically responsible, avoiding trade-offs that harm future generations.

Option C:
Option C is incorrect because environmental sustainability does not require abandoning poverty reduction or health improvements. Instead, it calls for achieving these goals in ways that respect ecological boundaries.

Option D:
Option D is incorrect as human development explicitly goes beyond income, taking into account health, education and freedoms. Environmental issues are increasingly recognised as fundamental to sustaining these achievements.

Statement D is the only wrong statement because population ageing clearly has implications for planning services, infrastructure and resource use. Statements A, B, C, E and F are correct: ageing populations need adapted services, age-friendly design, they contribute to environmental action, heatwaves pose higher risks to them and DRR must consider ageing. Therefore, the correct answer is the combination that identifies D alone as wrong.

Option A:
Option A is incorrect as it groups A with D as wrong, even though A correctly highlights increased demand for adapted services in ageing societies. Treating A as wrong contradicts demographic and planning evidence.

Option B:
Option B is incorrect because it labels C and D as wrong together. C accurately points out that older persons often contribute knowledge and voluntary efforts, so including it with D is unjustified.

Option C:
Option C is incorrect since it combines D with E as wrong. E is correct in noting that climate risks like heatwaves can disproportionately affect older urban residents, as seen in many city experiences.

Option D:
Option D is correct because it singles out D, which wrongly claims that ageing has no planning implications, and implicitly accepts A, B, C, E and F as true. It is consistent with the unit’s emphasis on demographic change and environmental planning.

Statements A, B, C and E are correct because they describe multi-actor governance, unequal burdens on disadvantaged groups, location of informal settlements and the role of participation in improving accountability. Statement D is false since user charges can be designed with lifeline tariffs or subsidies to protect poorer users. Statement F is false because decentralisation outcomes depend on power structures, capacity and accountability mechanisms. Thus, the option containing A, B, C and E while excluding D and F is correct.

Option A:
Option A is incorrect as it omits E and therefore does not mention participatory budgeting and planning, which are important innovations for more inclusive urban governance.

Option B:
Option B is incorrect because it excludes C, so it fails to emphasise the spatial concentration of disadvantaged groups in high-risk locations, which is central to urban environmental inequities.

Option C:
Option C is correct since it integrates governance structures, justice concerns, spatial patterns and participatory tools, while rejecting simplistic claims about user charges and decentralisation.

Option D:
Option D is incorrect as it includes D, which claims user charges cannot be pro-poor, even though carefully designed tariffs can protect vulnerable users.

Statements A, B, D and E are correct because agrobiodiversity covers crops, livestock and associated species, genetic diversity improves resilience, on-farm conservation preserves varieties and dietary diversity relies on a range of species and products. Statement C is wrong since monocultures often reduce resilience by narrowing genetic bases, and F is wrong because seed and gene banks are central ex situ tools for conserving agricultural biodiversity. Thus, the correct combination must include A, B, D and E while excluding C and F.

Option A:
Option A is incorrect because it lists only A, B and D and omits E, thereby ignoring the important link between diversity on farms and diversity on plates. Since dietary diversity is a widely recognised outcome of agrobiodiversity, leaving out E makes the answer incomplete.

Option B:
Option B is incorrect as it includes C, which wrongly asserts that monocultures always enhance resilience, and omits E. Accepting C contradicts evidence that genetically uniform systems can be highly vulnerable to shocks, so this combination mixes valid and invalid statements.

Option C:
Option C is correct since it gathers all four true statements about the roles and implications of agrobiodiversity and excludes the two that misrepresent monoculture effects and the role of gene banks. It provides a balanced view encompassing production, resilience, conservation and nutrition.

Option D:
Option D is incorrect because it includes F, which treats gene banks as irrelevant, even though they are key institutions for conserving genetic resources, and omits A, which defines agricultural biodiversity itself. As a result, this option fails both on definition and on conservation mechanisms.

Environmental Impact Assessment is a preventive environmental management tool used before major projects are approved. Its primary role is to identify and predict potential environmental impacts, evaluate their significance and suggest mitigation measures. By doing so, it helps decision makers consider environmental costs and benefits alongside economic and social factors. Therefore, the main purpose of EIA is impact identification and evaluation prior to decision-making, as indicated in option C.

Option A:
Option A is incorrect because EIA is not a funding mechanism; it does not provide financial assistance. It is an assessment process used to guide decisions on whether and how a project should proceed.

Option B:
Option B is incorrect since EIA may lengthen approval time due to detailed studies and consultations. Its aim is environmental safeguards, not speedy clearance.

Option C:
Option C is correct because it clearly states the core activities of EIA: identifying, predicting and evaluating environmental impacts before decisions. This allows potential negative effects to be avoided, reduced or compensated.

Option D:
Option D is incorrect because increasing land value is not an objective of EIA. Any rise or fall in land prices is incidental and not part of the assessment’s purpose.

Standard disaster risk frameworks express risk as a combination of hazard,exposure and vulnerability. Vulnerability captures the susceptibility of elements at risk to damage, given a hazard of certain intensity. The stem refers to this tripartite conceptualisation,so vulnerability correctly completes the expression.

Option A:
Vulnerability encompasses physical, social, economic and environmental factors that increase the likelihood of harm. Even with the same hazard and exposure, communities with lower vulnerability experience less disaster impact. This fits exactly with the role described in the question.

Option B:
Relief is the immediate assistance provided after a disaster and is part of response,not a component of risk. While important, it does not define the likelihood of loss before an event occurs.

Option C:
Reconstruction involves rebuilding infrastructure and livelihoods in the long term recovery phase. It takes place after a disaster has happened and is not part of the risk formula.

Option D:
Mitigation denotes measures taken to reduce disaster risk by lowering vulnerability or modifying hazards. It is an action applied to components of risk rather than one of those components itself.

Large-scale LED deployment reduces electricity consumption for lighting, which is a major urban end-use. Lower energy use translates into reduced emissions intensity of GDP when the power system still relies partly on fossil fuels. Such efficiency improvements also free up electricity for other productive uses, supporting development. The initiative therefore aligns well with India’s Panchamrit commitments on emissions intensity and clean energy, as well as with broader goals of sustainable urbanisation. (The Times of India)

Option A:
This option correctly links LED rollouts to India’s climate and development vision, where efficiency measures reduce emissions while improving services. It recognises that efficient public lighting contributes to both mitigation and better quality of life.

Option B:
This option is incorrect because the LED programme supports, rather than undermines, the growth of renewables by lowering demand growth and improving system flexibility. Phasing out renewables in favour of coal would contradict India’s stated climate targets.

Option C:
The purpose of the programme is to reduce energy use for a given level of lighting, not to encourage unnecessary lighting. While careful planning is needed to avoid light pollution, the policy focus is efficiency, not more wasteful illumination.

Option D:
Replacing grid-based lighting with diesel generators would increase emissions and costs, going against the rationale for LED deployment. The initiative is about cleaner and more efficient electricity use, not shifting to more polluting fuels.

Statements A, B and D correctly outline features of local environmental planning. Local bodies indeed plan for waste, water and green areas, people’s participation enhances implementation and integrating local knowledge can make plans more effective and context-specific. Statement C is incorrect because local actions aggregate to influence global outcomes, and local planning is essential for achieving broader environmental goals. Thus, the correct combination is A, B and D only.

Option A:
Option A is correct as it brings together the relevant governance, participation and knowledge aspects and excludes the dismissive statement C. It highlights that local planning has both local and broader significance. Therefore, it aligns with the unit’s emphasis on decentralised environmental management.

Option B:
Option B is incorrect because it omits D, which is a valid statement about the value of local and traditional knowledge. This omission makes the description of local planning less comprehensive.

Option C:
Option C is incorrect since it includes C and treats it as correct along with B and D. C wrongly claims that local planning is irrelevant to global issues, ignoring the importance of local-level implementation for global agreements. Hence, this combination cannot be accepted.

Option D:
Option D is incorrect as it groups A, C and D, thereby accepting C as correct. Although A and D are true, retaining C undermines the logic of multi-level environmental governance.

Statements A, B and D are correct because they describe the standard classification of ecosystem services and give examples of regulating and cultural services. Provisioning, regulating, cultural and supporting services are recognised in major assessments, and pollination and climate regulation are key regulating services. Recreation and spiritual values are central cultural services. Statement C is incorrect since the concept explicitly links ecosystem functioning to human well-being. Thus, A, B and D together form the correct combination.

Option A:
Option A is incomplete as it includes only A and B and omits D. Without cultural services, the answer fails to capture the full range of acknowledged ecosystem service categories.

Option B:
Option B is correct because it groups all accurate statements and excludes C, which wrongly claims that human well-being is ignored. This reflects the accepted framework used in environmental economics and ecology.

Option C:
Option C is incorrect because it accepts C along with B and D. Including C undermines the purpose of the ecosystem services framework, which is precisely to highlight human dependence on ecosystems.

Option D:
Option D is incorrect as it combines A with C and D and treats C as true. Although A and D are correct, the presence of C makes the overall combination conceptually wrong.

Statement B is the only wrong statement because coercive measures such as forced sterilisation contradict the principles of human rights and voluntary, informed choice that underlie rights-based population policies. Statements A, C, D, E and F are correct: they describe voluntary approaches, the role of services, education’s influence on fertility, the importance of gender equality and the benefits of integrating reproductive health with broader programmes. Therefore, the correct answer is the option that identifies B alone as wrong.

Option A:
Option A is correct because it isolates B as the single statement that conflicts with contemporary human rights frameworks while treating all the other statements as accurate reflections of rights-based population and reproductive health policies. It aligns with international agreements that emphasise voluntarism and autonomy.

Option B:
Option B is incorrect as it groups C with B, even though C correctly states that reproductive health services influence fertility and maternal health. Including C as wrong would deny strong evidence about service access and demographic outcomes.

Option C:
Option C is incorrect since it treats A and C as wrong along with B. Statements A and C are central to rights-based approaches and service-oriented population policy, so this combination misclassifies two correct statements.

Option D:
Option D is incorrect because it adds D and E to B as wrong statements. In reality, D and E accurately highlight the roles of girls’ education and gender equality, so grouping them with a coercive approach is conceptually inconsistent.

Statements C and F are wrong, while A, B, D and E are correct. Disaster risk is shaped by hazard, exposure and vulnerability, so focusing only on hazard magnitude ignores why some people are more affected. Disasters are not purely natural; human decisions about where and how to build strongly influence impacts. The other statements correctly highlight how bad development creates risk, how disasters erode development gains, how investment in resilience helps, and how inequality shapes impacts. Thus, the wrong statements together are C and F.

Option A:
Option A is incorrect because it identifies only C as wrong and ignores F, which also misrepresents disasters as purely natural. As a result, it fails to list all the incorrect statements required.

Option B:
Option B is incorrect since it includes D as wrong along with C, even though D correctly states that investing in risk reduction protects development investments. Misclassifying D undermines current thinking in disaster risk reduction.

Option C:
Option C is incorrect because it treats E as wrong in addition to C and F. Statement E is correct in noting that social inequality affects who suffers most, so grouping it with wrong statements makes the option invalid.

Option D:
Option D is correct as it selects exactly C and F, both of which deny key elements of risk creation and responsibility. It aligns with the understanding that disasters are shaped by social conditions, not just by natural hazards.

Statements A and C are correct and illustrate curriculum and campus-based approaches in higher education. Integration of environmental themes across disciplines and project work, as well as practical exercises like audits, strengthen learning and awareness. Statements B and D are incorrect because environment and sustainability are relevant to all students and participation in clubs does influence attitudes and behaviours. Therefore, the combination that includes A and C while excluding B and D is the correct answer.

Option A:
Option A is correct because it picks precisely those statements that align with policy recommendations for mainstreaming environmental education. It recognises cross-disciplinary curriculum integration and experiential learning through campus initiatives, both of which are supported by higher education reforms. Excluding B and D avoids endorsing narrow or dismissive views of environmental learning.

Option B:
Option B is incorrect because it adds statement B, which wrongly restricts environmental learning to environmental science students. Sustainability issues cut across all fields including commerce, humanities and engineering, so including B in the set of correct statements is conceptually wrong.

Option C:
Option C is incorrect as it includes statement D along with A and C. While A and C are correct, D is false because environmental clubs and societies are known to foster pro-environmental attitudes and behaviours among students. The presence of D invalidates this option.

Option D:
Option D is incorrect because it includes B and D, both of which misrepresent the scope and impact of environmental education, along with C. Accepting these false statements means the combination cannot be treated as correct.

The Global Stocktake synthesised scientific and policy assessments showing that current efforts are insufficient for 1.5°C. Its decision text therefore urges a transition away from fossil fuels, recognising different national circumstances and the need for just transitions. It also sets collective signals to triple global renewable energy capacity and double rates of efficiency improvement by 2030, guiding investment and planning decisions worldwide.

Option A:
This option misrepresents the decision; there is no carte blanche for fossil expansion based on tree planting alone.

Option B:
This option accurately reflects the key energy-system messages of the stocktake and links them to justice and 1.5°C-compatible development pathways.

Option C:
The decision reaffirms, rather than removes, the Paris temperature limits, so this option is incorrect.

Option D:
The stocktake covers mitigation, adaptation and support; it is not limited to adaptation.
