CFA Institute Updated ESG-Investing Exam Questions and Answers by zunaira

An Emissions Trading System (ETS), also known as a cap-and-trade system, is designed to control and reduce greenhouse gas (GHG) emissions by setting a total emissions cap and allowing participants to trade allowances.

How it works:

A government or regulator sets a cap on total emissions.

Companies receive or buy carbon allowances (permits to emit a certain amount of CO₂).

Companies can trade allowances—if they emit less, they can sell excess permits; if they emit more, they must buy additional permits.

Key examples:

EU Emissions Trading System (EU ETS) (largest globally)

California Cap-and-Trade Program

China’s National Carbon Market (launched in 2021)

Why not A or B?

A is incorrect because an ETS does not directly set a price on carbon—it allows the market to determine the price based on supply and demand.

B is incorrect because an ETS does not involve direct investment in renewable energy (that would be carbon offset programs).

The European Union Audit Reform (Regulation (EU) No 537/2014) imposes strict rules on audit firms to ensure independence and reduce conflicts of interest.

Why C is correct:

The EU restricts non-audit services that auditors can provide to clients they audit.

A monetary cap of 70% of audit fees is imposed on permissible non-audit services to limit financial dependence.

These measures ensure auditors do not compromise audit quality by having financial incentives to approve misleading financial statements.

Why not A or B?

A is incomplete—a list of allowable services alone does not limit the financial influence of consulting fees.

B is incomplete—a monetary cap alone does not specify which services are prohibited.

Quantitative ESG analysis involves analyzing measurable data such as issuer-reported metrics, third-party ESG scores, and other numerical ESG indicators to assess performance. (ESGTextBook[PallasCatFin], Chapter 7, Page 374)

Companies integrating ESG into operations enhance efficiency through improved resource management, governance, and stakeholder engagement.

Why A (Efficiency) is correct:

ESG initiatives lead to cost savings, innovation, and better risk management.

Example: Energy-efficient supply chains reduce waste and increase productivity.

Why not B or C?

B (State intervention) is incorrect—proactive ESG efforts often reduce regulatory risks.

C (Negative externalities) is incorrect—effective ESG integration minimizes externalities, not increases them.
