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.

Competence greenwashingoccurs when a companymisrepresents its ESG knowledge or expertise, such asoverstating the board’s sustainability qualifications.

Option C describes “selective disclosure” greenwashingrather than competence greenwashing.

Governments and corporations can take steps to internalize externalities,such ascarbon pricing, emissions regulations, or corporate sustainability initiatives.

Externalities (A) are not always reflected in market prices.

Negative externalities mean societal costs exceed private costs, not the other way around (B).

Governance data is generally the easiest to optimize in a portfolio because it ismore standardized, quantifiable, and widely disclosedcompared to social and environmental data. Corporate governance indicators, such as board composition, executive compensation, and shareholder rights, are commonly reported in financial statements and regulatory filings.

In contrast, environmental and social data can be moresubjective, complex, and inconsistentdue to varying reporting standards and lack of historical data. For example, carbon emissions (E) and employee well-being (S) often lack standardized disclosures across regions and industries.
