Key Terms

5 terms

scope 1 technical

"near-term Scope 1, 2, and 3 greenhouse gas (GHG) emissions reduction targets"

Scope 1 are the greenhouse gas emissions a company produces directly from sources it owns or controls, like fuel burned in company vehicles, boilers, or on-site factories. Think of it as the smoke coming out of a business’s own chimney versus electricity it buys from the grid. Investors watch Scope 1 because these direct emissions can create regulatory costs, operational changes, and reputational risks that affect profitability and long-term value.

scope 2 technical

"near-term Scope 1, 2, and 3 greenhouse gas (GHG) emissions reduction targets"

Scope 2 covers the greenhouse gas emissions produced indirectly when a business uses energy it buys from others—most commonly electricity, but also steam, heating or cooling. Think of it like the pollution linked to your household’s electricity bill: you didn’t burn the fuel yourself, but your consumption still causes emissions. Investors watch Scope 2 because it affects a company’s climate footprint, energy costs, regulatory exposure and reputation, all of which can influence long‑term financial performance.

scope 3 technical

"near-term Scope 1, 2, and 3 greenhouse gas (GHG) emissions reduction targets"

Scope 3 describes all greenhouse gas emissions that occur upstream and downstream of a company’s direct operations—things like emissions from suppliers, transportation, product use, and disposal. Think of it as the hidden carbon footprint tied to everything a business buys, sells, or enables; it matters to investors because these indirect emissions can drive regulatory costs, supply-chain disruption, consumer preference shifts, and long-term valuation risk that aren’t visible on a company’s factory floor or utility bill.

ghg technical

"greenhouse gas (GHG) emissions reduction targets"

Greenhouse gases (GHGs) are air pollutants like carbon dioxide and methane that trap heat in the atmosphere, similar to how a blanket holds in body warmth. For investors, GHGs matter because companies' emissions affect regulatory costs, reputational risk, and long-term business viability as governments and consumers push for lower emissions; measuring and reducing GHGs can signal future compliance, efficiency gains, or potential liabilities.

sasb regulatory

"disclosures related to The Sustainability Accounting Standards Board (SASB)"

SASB stands for the Sustainability Accounting Standards Board, an organization that created industry-specific guidelines for companies to report environmental, social and governance factors that are likely to affect their financial performance. Think of it as a standardized checklist that helps investors compare how well different companies manage risks like pollution, labor practices or product safety — similar to using a common recipe so you can fairly judge different cooks. Clear, consistent SASB disclosures make it easier for investors to spot hidden risks and long-term value drivers.
