Key Terms

6 terms

scope 1 and 2 greenhouse gas emissions financial

"Total global scope 1 and 2 greenhouse gas (“GHG”) emissions were 198,110 tonnes"

Scope 1 and 2 greenhouse gas emissions are the carbon and other greenhouse gases a company produces directly and indirectly from its energy use: Scope 1 covers emissions from sources the company owns or controls (like fuel burned in company vehicles or boilers), while Scope 2 covers emissions tied to purchased electricity, heat or steam. Investors care because these emissions affect regulatory costs, operating expenses, reputation and long-term risk exposure — like a company’s “tailpipe” and its “electric bill” for climate impact.

emissions intensity financial

"Emissions intensity per ounce of gold equivalent produced ... was 0.37 tCO2e"

Emissions intensity measures how much greenhouse gas a company releases for each unit of output — for example, tons of CO2 per dollar of revenue, per megawatt-hour of electricity, or per ton of product. Investors treat it like a fuel-efficiency rating: lower intensity means a business creates less pollution for the same output, which can signal lower regulatory, operational and reputational risks and potential cost advantages over time.

ISO 50001 technical

"Öksüt earned several site-level certifications including ISO 50001 energy management system"

Zero Waste certifications technical

"ISO 14046 Water Footprint and Zero Waste certifications, reinforcing efforts taken"

World Gold Council’s Responsible Gold Mining Principles regulatory

"5 years of independently assured conformance with the World Gold Council’s Responsible Gold Mining Principles"

local procurement financial

"Local procurement spending across all operating jurisdictions increased by 43% from 2024"
