UGC NET Questions (Paper – 1)

Carbon credits are units created when a project or activity demonstrably reduces or removes greenhouse gas emissions compared to a baseline. Each credit corresponds to a specific quantity, often one tonne of CO₂ equivalent, and can be traded and used for compliance in emissions trading schemes.

Option A:
Option A is incorrect because credits reward emission reductions, not fossil fuel production; fossil fuel subsidies undermine mitigation goals.

Option B:
Option B is correct as it emphasises both the tradable nature and the quantified emission reduction or removal that a credit represents.

Option C:
Option C is incorrect since a tax on renewable energy would discourage clean energy and is unrelated to the concept of credits.

Option D:
Option D is incorrect because credits exist within capped or regulated systems and do not give unlimited permission to pollute; entities must hold enough credits to match their emissions.

A carbon credit is a unit used in emissions trading schemes that typically corresponds to one tonne of carbon dioxide equivalent reduced or removed from the atmosphere. Firms or countries that over achieve their targets can sell surplus credits to others. The stem describing a tradable certificate for one tonne of emissions reduction fits this definition exactly,so carbon credit is the correct term.

Option A:
Carbon credit schemes aim to lower overall mitigation costs by allowing reductions where they are cheapest. They also create financial incentives for emissions saving projects. This function aligns with the trading and reduction emphasis in the question.

Option B:
Carbon footprint refers to the total greenhouse gas emissions associated with an activity,person or product. It is a measure of impact,not a tradable certificate,so it does not match the stem.

Option C:
Carbon tax is a levy on carbon content of fossil fuels or on emissions themselves. It is a fiscal policy instrument rather than a unit that can be bought and sold in markets,so it is not the correct option.

Option D:
A carbon sink is a process or reservoir,such as forests or oceans,that absorbs more carbon than it emits. While projects that enhance sinks can generate carbon credits, the sink itself is not the tradable certificate described in the question.

In cap-and-trade or similar schemes, a carbon credit typically represents permission to emit a specified quantity of greenhouse gases, often measured as one tonne of CO₂-equivalent. These credits can be bought and sold, allowing entities that cut emissions cheaply to sell excess allowances to those facing higher costs. Hence, the core idea is a tradable emission permit.

Option A:
Option A is correct because it describes carbon credits as quantifiable, tradable rights or allowances to emit a certain amount of greenhouse gases under an overall cap.

Option B:
Option B is incorrect because no certificate can guarantee that a country will never emit greenhouse gases; carbon credits regulate and price emissions, they do not eliminate them entirely.

Option C:
Option C is incorrect since a document showing forest area is about land cover and potential carbon sinks, not a tradable emission permit unit.

Option D:
Option D is incorrect as income tax receipts relate to general fiscal policy, not specifically to climate mitigation instruments like credits and trading.

Statements C and D are wrong, whereas A and B correctly describe carbon taxes and emissions trading. Market-based instruments are important but usually need to be complemented by regulations, technology policies and behavioural measures, so they are not always sufficient on their own. Fossil fuel subsidies in fact encourage continued use of high-carbon fuels and hinder transitions to low-carbon systems. Therefore, the wrong statements are C and D together.

Option A:
Option A is incorrect because it picks C only and ignores D, even though fossil fuel subsidies also contradict the idea of low-carbon transition. Selecting only C fails to identify all wrong statements.

Option B:
Option B is correct as it recognises that both C and D misrepresent mitigation policies. It acknowledges the complementary role of regulatory instruments and notes that fossil fuel subsidies are inconsistent with climate goals. This combination therefore matches the requirement to select the wrong statement or statements.

Option C:
Option C is incorrect because it includes B, C and D as wrong. Statement B is actually correct in explaining how cap-and-trade systems work, so grouping it with the wrong statements makes this option invalid.

Option D:
Option D is incorrect since it singles out D only as wrong and treats C as correct. Accepting C would imply that market instruments alone make regulations redundant, which is not supported by climate policy practice.

In a cap and trade system, the government sets an overall “cap” on allowable emissions and allocates or auctions permits that add up to this cap. Firms that can reduce emissions cheaply may sell surplus permits to others,creating a market price for pollution. The stem describes this type of system with a limit and tradable permits,so the missing word is cap. Hence Option C is correct.

Option A:
Tax and trade is not a standard phrase. Pollution taxes operate differently by charging a fee per unit of emissions rather than fixing a quantity cap and allowing trading within that cap.

Option B:
An offset typically refers to a project or activity that compensates for emissions made elsewhere,for example through tree planting. While offsets can sometimes be linked to trading schemes,they are not the defining word in the cap and trade expression.

Option C:
Cap emphasises that the total quantity of emissions is limited to a specified level,ensuring an environmental outcome. Trading then allows flexibility in how reductions are distributed. This two part mechanism is exactly what the question refers to.

Option D:
Ratio and trade is not a recognised policy term in environmental economics. It would not convey the core idea of a fixed overall limit on emissions,so it is not an appropriate answer.
