Key Terms

scope 1 technical

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.

market-based scope 2 technical

Emissions from a company’s purchased electricity measured using the market-based method, which counts the carbon intensity tied to specific contracts, suppliers, or certificates the company chooses (for example, power-purchase agreements or renewable energy certificates) rather than the average grid mix. Investors care because this measure shows the emissions impact the company claims through its contractual choices, affecting corporate climate disclosures and comparability of reported footprints across firms.

scope 3 technical

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.

fleet telematics technical

Fleet telematics is the combination of hardware (like GPS and sensors) and software that collects real-time data from commercial vehicles to track location, fuel use, driving behavior, and maintenance needs. For investors, it matters because this system helps companies cut operating costs, improve safety and delivery reliability, and extend vehicle life—similar to how a fitness tracker helps a person monitor health and adjust habits to avoid costly problems.
