CFA Institute Sustainable-Investing Based on Real Exam Environment

TheKyoto Protocol(adopted in 1997) was the firstinternational treatyto legallycommit industrialized nationstoreduce greenhouse gas emissions. It setbinding targetsfor developed countries but did not impose obligations on developing nations.

Options A and B are incorrect becauseKyoto focused on emission reductionsrather than corporate disclosures or private finance mobilization.

TheKigali Amendment to the Montreal Protocol(adopted in 2016) is alegally binding international agreementthat aims to phase down the production and consumption ofhydrofluorocarbons (HFCs)—potent greenhouse gases used in refrigeration and air conditioning. Unlike theMontreal Protocol, which focused on ozone-depleting substances, the Kigali Amendment directly addresses climate change by reducing HFC emissions.

The Nagoya Protocol (A) deals with biodiversity and genetic resources, while the Basel Convention (B) regulates hazardous waste.

ESG factors can create new sub-asset classes(e.g.,green bonds, impact investing funds) that affectrisk-return trade-offs in mean-variance optimization (MVO) models.

MVO assumes that ESG factors can impact risk-adjusted returns, meaning ESG data can influenceasset weightings and expected volatility.

Regional asset mixes (B) are still relevant for ESG investing, and ESG factorsdo impact expected returns and volatility (C).

Thelargest driverof global greenhouse gas (GHG) emissions iscarbon dioxide (CO₂) from fossil fuels and industry, accounting for approximately75% of total GHG emissions. This includes emissions from coal, oil, and natural gas combustion for energy, manufacturing, and transportation.

While land-use change (C) contributes significantly (~10–15%), and methane (A) is a potent GHG,CO₂ from fossil fuels remains the dominant factordriving climate change.
