Scope 1 and 2 carbon emissions regulatory

"Achieved its 2025 target for reducing Scope 1 and 2 carbon emissions per passenger"

Scope 1 and Scope 2 carbon emissions categorize a company's greenhouse gas output: Scope 1 covers direct emissions from sources the company controls (like fuel burned on-site or company vehicles), while Scope 2 covers indirect emissions from purchased energy (such as electricity or steam). Investors use these measures like a carbon balance sheet—showing where emissions come from, which helps judge regulatory, cost and reputational risks, compare firms, and track progress on reduction targets.

Airport Carbon Accreditation (ACA) Level 3 "Optimization" regulatory

"All 13 airports renewed Airport Carbon Accreditation (ACA) Level 3 "Optimization" certification"

GRI Standards regulatory

"The 2025 Sustainability Report has been prepared in accordance with the GRI Standards"

A set of international guidelines for how organizations report environmental, social and governance (ESG) information, the GRI Standards act like a common recipe that helps companies consistently disclose their impacts on people and the planet. Investors use these reports to compare sustainability-related risks and opportunities across companies, much like using a standardized checklist to judge different products, which improves transparency and helps inform long-term investment decisions.

SASB Standards regulatory

"Includes industry-specific disclosures based on the SASB Standards"

SASB standards are industry-specific guidelines that tell companies which environmental, social and governance issues are most likely to affect their financial performance and should be disclosed to investors. Think of them as a practical checklist or scorecard that helps investors compare companies on risks like pollution, worker safety or data security in a consistent way, making it easier to assess long-term value and risk.

Socially Responsible Company (ESR) regulatory

"Recognized as a Socially Responsible Company (ESR) for the fifteenth consecutive year"
