The Global Travel Impact Score is based on a rigorous CO2 emissions calculation for businesses within the travel sector. We assess companies across various metrics—such as energy consumption, transportation impact, and waste management—to provide a transparent and comparable score.

Aligning with International Standards

The Global Travel Impact (GTI) Score is built upon internationally recognized sustainability frameworks to ensure a reliable and standardized assessment of environmental performance in the travel industry. It aligns with the Greenhouse Gas (GHG) Protocol, the world's most widely used standard for measuring and managing greenhouse gas emissions. Additionally, the GTI Score integrates principles from ISO 14064 (Greenhouse Gas Accounting and Verification) and ISO 14001 (Environmental Management Systems) to provide a credible and science-based evaluation of travel-related emissions.

Sustainability is shaping the future of travel, driven by Gen Z’s growing influence and preference for ethical, transparent practices. Over the next 20 years, their purchasing power will define industry standards.

The GTI Score provides a clear rating for eco-conscious travelers and helps businesses stay competitive by adopting sustainable practices. As regulations tighten and demand for transparency grows, the GTI Score enables companies to reduce emissions, build trust, and future-proof their operations while contributing to a greener travel industry.
