Climate change (Option A) is a material financial risk that pension fund trustees must consider under their fiduciary duty. Failing to assess climate risks can lead to:
Legal liabilities and lawsuits from beneficiaries.
Financial losses due to stranded assets and regulatory shifts.
Option B (Choice of benchmarks) is relevant, but not the primary fiduciary risk.
Option C (Lack of ESG signals) affects engagement but does not constitute a direct legal risk.

Companies with a more diverse board of directors are most likely associated with lower stock return volatility.
This relationship is based on the following factors:
* Improved Decision-Making: A diverse board brings a range of perspectives and experiences, leading to more comprehensive and balanced decision-making processes. This can result in better risk management and more stable corporate performance.
* Enhanced Reputation and Trust: Diversity on the board can enhance a company's reputation, leading to greater trust from investors, customers, and other stakeholders. This can contribute to more stable stock performance.
* Risk Mitigation: Diverse boards are better equipped to identify and mitigate risks, including ESG-related risks. Effective risk management can reduce the likelihood of negative events that could cause stock price volatility.
* Long-Term Focus: Companies with diverse boards are often better at focusing on long-term strategic goals rather than short-term gains. This long-term perspective can contribute to more consistent and stable stock returns.

The risk that customers will switch to lower GHG energy sources would primarily impact future revenues. It reflects the potential loss of market share to more environmentally friendly competitors. (ESGTextBook[PallasCatFin], Chapter 7, Page 368)

According to the Capitals Coalition, the stock of renewable and non-renewable natural resources that combine to yield a flow of benefits to people is best described as natural capital. Here's a detailed explanation:
* Natural Capital:
* Natural capital refers to the world's stocks of natural assets including geology, soil, air, water, and all living things. It is from this natural capital that humans derive a wide range of ecosystem services that make human life possible.
* The Capitals Coalition defines natural capital as the stock of renewable and non-renewable natural resources (such as plants, animals, air, water, soils, and minerals) that combine to yield a flow of benefits to people.
CFA ESG Investing References:
* The CFA Institute's ESG curriculum discusses natural capital extensively, emphasizing its importance in sustainable investing and the need for integrating natural capital considerations into financial decision-making.

The Inflation Reduction Act (IRA) of 2022 is the largest U.S. investment in climate action, focusing on clean energy incentives, tax credits, and subsidies.
Why A (Clean energies) is correct:
The IRA allocates $369 billion toward energy security and climate change initiatives, with the majority going to clean energy technologies such as:
Renewable energy (solar, wind, geothermal)
Energy storage systems
Hydrogen energy and biofuels
Why not B or C?
B (Clean transport) receives significant investment (EV tax credits, charging infrastructure) but is not the largest category.
C (Clean electricity) benefits indirectly, but the IRA prioritizes energy sources rather than distribution.
