Cuestionario: Introduction to Carbon Pricing and Emissions Trading — 10 preguntas

1. What best describes a carbon tax rate?

A. A voluntary fee paid only by large firms

B. A fixed government price per ton of emitted greenhouse gas

C. A tradable permit price set by market auction

D. A declining cap on total annual emissions

Answer: (B)

Explicación

A carbon tax rate is a fixed per-ton government charge on greenhouse gas emissions. The other options describe features of trading systems or caps, not a tax rate.

2. Which factor is identified as affecting how effective a carbon tax will be?

A. The number of firms holding allowances in circulation

B. The annual auction calendar for permit sales

C. The legal linking status with foreign carbon markets

D. Demand elasticity and the degree of cost pass-through

Answer: (D)

Explicación

Carbon tax effectiveness depends on the tax rate, demand elasticity, and how much firms can pass costs to consumers. The other choices relate more to ETS design than to tax effectiveness.

3. What is an emission trading system (ETS)?

A. A compliance market created under law that uses tradable allowances

B. A voluntary offset program with no regulatory obligations

C. A subsidy scheme for low-carbon equipment purchases

D. A fixed-price environmental levy collected from all households

Answer: (A)

Explicación

An ETS is a legal compliance market that reduces emissions through tradable allowances. It is not a fixed tax or a voluntary program.

4. What must covered entities do to comply in an ETS?

A. Buy enough allowances for verified annual emissions and surrender them to the regulator

B. Request a new cap from the regulator each year

C. Pay a fixed per-ton charge directly to consumers

D. Trade only with firms outside their jurisdiction

Answer: (A)

Explicación

Covered entities must obtain allowances matching verified annual emissions and surrender them for compliance. The other options do not describe the standard compliance obligation in an ETS.

5. What is the main purpose of a periodic declining cap in cap-and-trade?

A. To reduce emissions by shrinking the number of permits over time

B. To keep emissions stable while prices remain fixed

C. To prevent allowance prices from changing between years

D. To replace trading with a direct carbon tax

Answer: (A)

Explicación

A periodic declining cap lowers total permitted emissions by reducing permit supply each year. That creates scarcity and pushes firms toward reductions.

6. Why can allowance prices rise in a cap-and-trade system when permits become scarce?

A. Because permits become identical to tax refunds

B. Because emissions are no longer measured annually

C. Because the regulator removes all compliance duties

D. Because firms may find abatement cheaper than buying scarce permits

Answer: (D)

Explicación

When permits are scarce, their price can rise until firms prefer investing in abatement rather than buying more allowances. The other options do not explain the price effect of scarcity.

7. What is a forward curve in a carbon market?

A. A fixed tax rate announced for the next decade

B. A legal schedule showing annual emissions caps only

C. A list of firms that received free allowances

D. A forward-looking set of carbon prices generated through derivatives contracts

Answer: (D)

Explicación

A forward curve is created by derivatives contracts and reflects expected future carbon prices. It is about future price expectations, not the cap schedule itself.

8. What is one benefit of linking ETS markets?

A. It converts the system into a carbon tax

B. It can create economies of scale and access to lowest-cost abatement opportunities

C. It removes the need for regulators to issue allowances

D. It guarantees that all permits will have the same price forever

Answer: (B)

Explicación

Linking markets expands the trading pool, which can lower costs and expose more low-cost abatement opportunities. The other choices are not stated benefits of linking.

9. Which program is listed as a major emissions trading program in the source material?

A. Fossil Fuel Support Scheme

B. International Clean Air Levy

C. Global Carbon Dividend Program

D. EU ETS

Answer: (D)

Explicación

EU ETS is named as a major active emissions trading program. The other options are not listed programs.

10. Which emissions trading program was developed independently before later linking with the EU ETS?

A. Tokyo Renewable Credit Scheme

B. Swiss ETS

C. California Cap-and-Trade Program

D. China National ETS

Answer: (B)

Explicación

Swiss ETS is identified as having been developed independently before linking with the EU. The other programs are not described that way in the source material.
