The Impact Score
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.
The 5-Star Rating System
5-Stars: Outstanding Sustainability Practices
Reserved for businesses that demonstrate exemplary practices with minimal CO₂ emissions. These companies excel in sustainable operations, energy efficiency, and environmental responsibility
4-Stars: Strong Environmental Commitment
Companies with a 4-star rating have strong sustainability initiatives and low CO₂ emissions relative to industry norms.
3-Stars: Moderate Sustainability Efforts
Businesses with moderate sustainability practices and average CO₂ impact within the industry. They meet basic sustainability standards and are on a path toward improvement.
2-Stars: Developing Environmental Awareness
Companies with emerging sustainability efforts and higher-than-average CO₂ emissions. They have begun to adopt eco-friendly practices but have substantial room for improvement.
1-Star: High Environmental Impact, Needs Improvement
Businesses with significant CO₂ emissions and minimal sustainability practices. They operate with limited regard for environmental impact and are encouraged to adopt more sustainable practices.
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.
By following these globally accepted methodologies, the GTI Score ensures consistency, transparency, and accountability. This alignment allows businesses to benchmark their environmental impact against international best practices, enabling them to take meaningful steps toward sustainability while giving travelers the confidence to choose low-carbon travel options.
Why the Global Travel Impact Score Matters
Sustainability is no longer just a trend—it’s a defining factor in the future of travel. As climate concerns grow, younger generations, particularly Gen Z, are emerging as key decision-makers and market influencers. Over the next 20 years, Gen Z’s purchasing power will expand significantly, shaping the travel industry with their strong preference for ethical, sustainable, and transparent business practices.
The GTI Score provides a clear, standardized rating that empowers eco-conscious travelers to make informed choices about where and how they travel. For businesses, adopting sustainable practices and achieving a higher GTI Score isn’t just about environmental responsibility—it’s about staying competitive in a market where Gen Z and future generations will increasingly prioritize sustainability in their purchasing decisions.
As governments tighten regulations on emissions and consumers demand greater transparency, the GTI Score helps travel companies proactively reduce their carbon footprint, differentiate themselves, and build trust with the next generation of travelers. By embracing sustainability today, businesses can future-proof their operations while contributing to a greener, more responsible travel industry.
